3 Reasons Behind Inadequate Testing of Mobile Apps

 he present century ushered in the era of mobile technology which has opened up many avenues for organizations to grow. This era also brought in various innovations. One such innovation is mobile applications that we now highly depend on for almost everything.  The Strategy Analytics App Ecosystem Opportunities (AEO) forecast - Mobile Apps Revenue Forecast: 2008 – 2017 – predicts that by 2017 the mobile app smartphone market will generate more than $35B growing from less than $1B in 2009.

However, according to a recent study by Capgemini and Sogeti in conjunction with HP, two- thirds of mobile application companies are inadequately testing their apps. It was found that in organizations that conducts quality assurance on mobile apps, 64% of them focused on performance, 46% on functionality while only 18 % on security. "Consistent and reliable software applications have become critical to the operations of many organisations. Yet the lack of confidence in most companies' internal abilities to monitor and test the quality of their software is resounding, particularly when it comes to mobile applications," said Michel de Meijer, Global Service Line Testing Lead, Capgemini Group.

Jennifer Lent on searchsoftwarequality.com highlighted some of the reasons why many software testing organizations are not giving mobile app testing the priority it deserves. Take a look at what she has to say.

Testing organizations are not serious about mobile apps

Many of the testing organizations look at mobile apps as "mini smartphone apps".  Steve Woodward from Cloud Perspectives said that many testing organizations have a mentality that the applications should work and it wouldn't be a big problem if there are defects in the application. Testing organizations shouldn't have this type of mentality as many of the applications that are flooding the market today are designed keeping in mind the various objectives of a business organization.

Evaluating the app performance in various environment
Mobile applications are expected to perform in the same way across different real world conditions. Testing mobile applications is restricted only to the labs and it is impossible to replicate the various conditions mobile application users will experience in the real world informed Matt Johnston from uTest.

A Low Price Tag
With the number of mobile applications increasing day by day, there is a cut throat completion among many developers to deliver an app with a lower price tag before the deadline for the release. Thus, to bring down the cost, many may restrict testing only to the performance and functionality aspects and ignoring the need to security test their apps.

5 Tips to Choose the Best Automated Mobile Testing Tool

 Mobile applications have revolutionized our lives. Today, with the touch of an option, we can access any amount of information such as getting directions to a restaurant, booking our flight tickets or even order a cab service. The shift from the more traditional desktops to smartphones has resulted in an increase in the demand for mobile applications.

However; the number of smartphones having different features and specifications are increasing daily and this poses many challenges to the testers. Brian MacKenzie in a blog post on northwaysolutions.com highlighted some tips to help mobile app testers choose the best automation tools to test applications.  

1) Reusable Scripts
Testers should ensure that the test scripts can be reused across the various devices running the same operating systems irrespective of the version. There are various solutions in the market today that claim to meet this requirement, however the reality is many of them don't although they come with tag lines such as "object based scripting" and "cross OS scripting".   

2) Support Emulators/Simulators and other Physical Devices
Testers should be able to run and record scripts across physical devices as well as simulators and emulators.

3) Web Application Support
Hybrid apps, web based apps and native apps have their own advantages and disadvantages not only to the developer but also to the testers and users. Hybrid and Web Based apps are becoming popular and they are likely to replace native apps. Before selecting the tool, the tester should ensure that it support all types of apps.
 
4) Interruptions Shouldn't Cause the Test to Fail
Common interruptions such as phone calls and messages shouldn't cause the test to fail. Testers should ensure that the tool doesn't get affected by the various interruptions and it should be able to resume once the interruption is over.

5) Integration with Performance Testing Tools
As poor application performance can affect the revenue, testers should ensure that the solution they plan to select can be integrated with other performance testing tool. Furthermore, the solution should be able to measure the performance of the RAM, disk, the battery and the CPU. 

5 Skills Every Tester Should Have

The ever increasing complexity of applications and the need of software applications in various business organizations have changed the face of software testing. The users expect their applications to be not only be user friendly but also defect free and this increased the responsibility of a tester. Testers are now viewed not only as a person who is responsible to find any bugs and defects in software but they are now viewed as a person who can instill some confidence into the minds of the users.

Milind Limaye on beyondtesting highlighted some of the skills that every tester is expected to possess.

1.    Communication
Testers are not only expected to be good listeners; however they are also expected to be good presenters as well. Testers need to communicate with the management, the users and the developers before, during and after development, prepare test cases, test logs and present the test reports. Communication skills of a tester include his/her body language, the tone, their writing style as well as the words they use.

2.    Domain Knowledge
Although testers are not expected to be domain experts; however they are expected to have a brief understanding about the application. This will help them identify the possible defects a user might face. According to Millind, the tester should keep the domain in mind when deciding on the priority of the bugs and defects, the test cases and the priority of the requirements. They should also be aware of the various domain complexities and the challenges.

3.    Desire to Learn
Testers are expected to keep themselves up to date with the various technologies, approaches, tools and techniques and apply them during testing. Testers should always remember that new tools may offer then some new and exciting features which can enhance their testing capabilities.

4.    Differentiate the Defects
Testers should have the ability to identify and differentiate the defects which need immediate attention and those that are severe. The test plan should include the various levels with regards to the priorities and severities of the bugs.

5.    Planning
Testers must be able to plan the testing process accordingly. The test plan should include the priorities of the various test cases, the number of defects that they are targeting, as well as all the functionalities, requirements and features.  A well planned test will lead to a high customer satisfaction.

CATT stands 4 Computer Aided Testing Tool

Although CATT is meant for as a testing tools, many SAP users have now use CATT frequently to upload vendors master data and make changes to other master record.

SAP Consultant and Abapers tends to used it for creating test data.

With CATT, you don't have to create any ABAP upload programs and this save on development time.  However, you still have to spend time on data mapping into the spreadsheet format.

The transactions run without user interaction. You can check system mesages and test database changes. All tests are logged.

What CATT does is record you performing the actual transaction once.

You then identify the fields that you wish to change in that view.

Then export this data to a spreadsheet to populate with the data required.

This is uploaded and executed saving you keying in the data manually.

To perform CATT, it has to be enabled in your production environment (your system administrator should be able to do this - SCC4).

You will also need access to your development system to create the CATT script.

SAP R/3 Testing Tool:

SAP R/3 Testing Tool:

SAP R/3 comes with an internal recording tool known as CATT (eCATT). One of the advantages of CATT (eCATT) is that since it is part of the standard SAP system it’s free of charge. However CATT does have some limitations which impel many companies to procure other test tools. 

There are many vendors offering commercial automated test tools and test management tools for testing SAP. Companies purchasing automated test tools expect and erroneously believe that the test tools will be the panacea to their entire SAP recording and testing needs. Unfortunately, this is not the case, since no two SAP implementations are exactly the same across two or more companies or at times even within different divisions of the same company. Consequently, a company implementing SAP might need to procure test tools from more than one vendor in addition to the CATT (eCATT) tool. 

An SAP implementation could be implementing SAP add-ons such as BW (Business Warehouse), APO (Advanced Planning Optimization), SEM (Strategic Enterprise Management) or even modules such as PS (Project Systems) that generate graphs and charts that a recording tool does not recognize. Furthermore, a company may move its SAP GUI from the desktop (fat client) to running SAP as web-based (thin client) or through an emulated Citrix session which could render the existing test tools useless. 

Companies that wish to move to an automated testing strategy should articulate and document what SAP modules and SAP add-ons they areinstalling in addition to any legacy applications integrating with SAP. This information should be provided to the vendors of automated test tools in order to determine what can actually be recorded and tested with the test tools. The company should further investigate with the vendor what additional benefits over CATT (eCATT) the automated test tools provide. The objective is to get the test tools that will maximize SAP recording.

2. You think that cross-site scripting is a fancy form of calligraphy.

1. You worry that if the private key doesn't open up a little more, it will never be accepted by its friends and public_key will always be the popular one.

Mobile Testing

Today's Mobile Applications deliver complex functionality on platforms having limited resources for computing. The Mobile environment comprises of plethora of devices with diverse hardware & software configurations. This diversity in Mobile computing environment presents unique challenges in quality assurance thus requiring unique testing strategies.

Challenges in Mobile Testing:

The challenges in Mobile testing arise from the diversity of device environment, hardware & networking considerations and methodologies of application development. The prime challenges are:

• Device Environment – There are almost 100 types of devices available in market with more than 40 Mobile browsers running on several operating systems. Rendering images, positioning of elements on screen, application runtime etc are just few of the areas one need to test across devices.
• Hardware & Network – Limitations in processing speed, Memory size of mobile devices, protocols used to communicate with outer world, network latency, gateways etc are the major challenges from a hardware & network perspective for Mobile testing.
• Scripts – This challenge arises from the choice of manual or automation testing scripts. Because of several different user interfaces working on several devices the script has to be build accordingly.

Critical Factors:

The critical factors that determine the success of any Mobile Testing project are:

• Mobile Environment testing
• Application complexity testing
• Use of emulators & actual devices
• Use of test automation

Mobile Testing Features:

The major features of Mobile Testing are:

• Functional Testing – Under functional testing the tests which are performed are Installation testing, System testing, Mobile Web content testing & Usability Testing. Security Testing is also done for Input Validation Checks & Authentication Checks.
• Performance Testing – Under performance testing the focus is on Test application responsiveness to user events, measure server response time in case of API calls, simulate multiple use request to perform load test & bandwidth choking to simulate mobile network speed.
• Usability & Compatibility Testing – This testing is done to understand how people interact with the platform, observe how the mass market use, avg. time taken for a use case, ease of use and recall, compliance against mobile usability standards, mobile browser compatibility test & multi-device compatibility check for OS, resolution, device level features etc
• Network Testing – In network testing, we test the application using multiple carriers, on different modes of connectivity, perform memory profiling, battery usage test for high data volume apps etc

Test Automation tools:

For building automation test scripts various tools are available in market (Open source as well as Commercial). Below is a sample list of the tools available:

Unit Testing	System Testing (Open source)	System Testing (Commercial)
jUnit	Robotium	M-euxTest
Roboelectric	Selenium	DeviceAnywhere
jMock	MonkeyRunner	Perfecto Mobile

Advantages of Agile Methodology

Agile as the name refers implies something to do very quickly. Hence Agile Testing refers to validate the client requirements as soon as possible and make it customer friendly. Agile development methodology is a conceptual framework for undertaking any software engineering projects. There are a number of agile software development methods but the most popular agile methods are Extreme Programming (XP) and Scrum.

In general agile methods attempt to minimize risk and maximize productivity by developing software in short iterations and deemphasizing work on interim work artifacts and it is people oriented. Here are some of the key characteristics of the agile methodology:

• Deliver frequently.
• More iteration.
• Less defects.
• Test frequently.
• Collaborative approach.
• Maximum ROI.

Top reasons for adopting Agile Methodology:

• Iterative and incremental delivery: Project delivery is divided into small functional releases or increments to manage risk and to get early feedback from customers and end users. These small releases are delivered on a schedule using iterations that typically last between one and four weeks each.
• Collaboration: All core project team members including an on-site customer are co-located in a shared, open area to facilitate face-to-communication and conduct interactions.
• Continuous Improvement: Practices that enable delivery process inspection and adaptation are integrated into agile methods. Project Reflections are meetings conducted while the project is underway to facilitate regular reflection on its successes and failures, and any of the tools and techniques applied.

ETL Testing / Data Warehouse Testing – Tips, Techniques, Process and Challenges

 ETL testing (Extract, Transform, and Load). This article will present you with a complete idea about ETL testing and what we do to test ETL process.

It has been observed that Independent Verification and Validation is gaining huge market potential and many companies are now seeing this as prospective business gain. Customers have been offered different range of products in terms of service offerings, distributed in many areas based on technology, process and solutions. ETL or data warehouse is one of the offerings which are developing rapidly and successfully.

Why do organizations need Data Warehouse?
Organizations with organized IT practices are looking forward to create a next level of technology transformation. They are now trying to make themselves much more operational with easy-to-interoperate data. Having said that data is most important part of any organization, it may be everyday data or historical data. Data is backbone of any report and reports are the baseline on which all the vital management decisions are taken.

Most of the companies are taking a step forward for constructing their data warehouse to store and monitor real time data as well as historical data. Crafting an efficient data warehouse is not an easy job. Many organizations have distributed departments with different applications running on distributed technology. ETL tool is employed in order to make a flawless integration between different data sources from different departments. ETL tool will work as an integrator, extracting data from different sources; transforming it in preferred format based on the business transformation rules and loading it in cohesive DB known are Data Warehouse.

Well planned, well defined and effective testing scope guarantees smooth conversion of the project to the production. A business gains the real buoyancy once the ETL processes are verified and validated by independent group of experts to make sure that data warehouse is concrete and robust.

ETL or Data warehouse testing is categorized into four different engagements irrespective of technology or ETL tools used:

• New Data Warehouse Testing – New DW is built and verified from scratch. Data input is taken from customer requirements and different data sources and new data warehouse is build and verified with the help of ETL tools.
• Migration Testing – In this type of project customer will have an existing DW and ETL performing the job but they are looking to bag new tool in order to improve efficiency.
• Change Request – In this type of project new data is added from different sources to an existing DW. Also, there might be a condition where customer needs to change their existing business rule or they might integrate the new rule.
• Report Testing – Report are the end result of any Data Warehouse and the basic propose for which DW is build. Report must be tested by validating layout, data in the report and calculation.

ETL Testing Techniques:

1) Verify that data is transformed correctly according to various business requirements and rules.
2) Make sure that all projected data is loaded into the data warehouse without any data loss and truncation.
3) Make sure that ETL application appropriately rejects, replaces with default values and reports invalid data.
4) Make sure that data is loaded in data warehouse within prescribed and expected time frames to confirm improved performance and scalability.

Apart from these 4 main ETL testing methods other testing methods like integration testing and user acceptance testing is also carried out to make sure everything is smooth and reliable.

ETL Testing Process:

Similar to any other testing that lies under Independent Verification and Validation, ETL also go through the same phase.

• Business and requirement understanding
• Validating
• Test Estimation
• Test planning based on the inputs from test estimation and business requirement
• Designing test cases and test scenarios from all the available inputs
• Once all the test cases are ready and are approved, testing team proceed to perform pre-execution check and test data preparation for testing
• Lastly execution is performed till exit criteria are met
• Upon successful completion summary report is prepared and closure process is done.

It is necessary to define test strategy which should be mutually accepted by stakeholders before starting actual testing. A well defined test strategy will make sure that correct approach has been followed meeting the testing aspiration. ETL testing might require writing SQL statements extensively by testing team or may be tailoring the SQL provided by development team. In any case testing team must be aware of the results they are trying to get using those SQL statements.

Difference between Database and Data Warehouse Testing
There is a popular misunderstanding that database testing and data warehouse is similar while the fact is that both hold different direction in testing.

•  Database testing is done using smaller scale of data normally with OLTP (Online transaction processing) type of databases while data warehouse testing is done with large volume with data involving OLAP (online analytical processing) databases.
•  In database testing normally data is consistently injected from uniform sources while in data warehouse testing most of the data comes from different kind of data sources which are sequentially inconsistent.
• We generally perform only CRUD (Create, read, update and delete) operation in database testing while in data warehouse testing we use read-only (Select) operation.
• Normalized databases are used in DB testing while demoralized DB is used in data warehouse testing.

There are number of universal verifications that have to be carried out for any kind of data warehouse testing. Below is the list of objects that are treated as essential for validation in ETL testing:
- Verify that data transformation from source to destination works as expected
- Verify that expected data is added in target system
- Verify that all DB fields and field data is loaded without any truncation
- Verify data checksum for record count match
- Verify that for rejected data proper error logs are generated with all details
- Verify NULL value fields
- Verify that duplicate data is not loaded
- Verify data integrity

ETL Testing Challenges:

ETL testing is quite different from conventional testing. There are many challenges we faced while performing data warehouse testing. Here is the list of few ETL testing challenges I experienced on my project:
- Incompatible and duplicate data.
- Loss of data during ETL process.
- Unavailability of inclusive test bed.
- Testers have no privileges to execute ETL jobs by their own.
- Volume and complexity of data is very huge.
- Fault in business process and procedures.
- Trouble acquiring and building test data.
- Missing business flow information.

Data is important for businesses to make the critical business decisions. ETL testing plays a significant role validating and ensuring that the business information is exact, consistent and reliable. Also, it minimizes hazard of data loss in production.

How to Deliver High Value Software Features using Agile Scrum Process

What is agile scrum (sprint) process?

Scrum is a software development process. In today's rapid world stakeholders want immediate return on their investments. They don't want to wait for longer periods to get full featured product. As a result, nowadays new software development and testing framework is catching momentum i.e. Scrum approach.

In scrum, projects are divided in small features to be developed and tested in specific time-frames called as sprint (small cycles). Features should get developed and tested in specified small time-frames.  This agile scrum team is handled by scrum master.

Scrum is an iterative, incremental framework for projects and products or application development. Scrum has become more and more popular software development and testing framework among organizations. Many small to large sized IT companies have started to embrace Scrum framework, as this can create excellent quality products in less time than other traditional methodologies. This framework can save companies both time and money.

Soft Skills for a Scrum Team:

What Soft Skills are required to be a Successful Scrum Team?

When we start our regular (Agile) sprints (Cycles of work), we usually find some of the challenges with our team members. These challenges are not part of technical difficulties.  It usually occurs with team member's mindset or their soft skills.  Many successful Scrum projects taught us that the success of scrum depends on how team members support whole heartedly towards the Sprint.

Let us discuss some of the pre-requisite soft skills for a Scrum Team.

Team Spirit

Cross functional Team work is at the heart of Scrum.  There is no "my work", "I have finished my work" and "your work". On a Scrum team we find only "Our work", "we have completed our Sprint".  Individuals will have helping tendency for sharing technical knowledge. Scrum Members are always available to team members rather than locked away behind closed doors.  Scrum Master will always motivate the teams and create a Supporting learning environment. Team will always be sprint-oriented and often discuss smooth run of the sprint. A scrum team's job is to self-organize around the challenges and management's job is to remove impediments to self-organization.

Communication

Good communication must exist among team members of development team, testing team, business analysts and stake holders. There must be highly collaborative interaction between client and the delivery teams. More client involvement implies more suggestions or changes from the client.  It implies more bandwidth for communication.

Commitment

Agile Teams needs periodic re-energizing to renew their commitments to their purpose and to each other.  Scrum Masters can help by ensuring that the team embraces the concept of whole-team responsibility and whole-team commitment to deliver working software at the end of each sprint. With the whole-team commitment, the team member who has completed his tasks will help the one who has not completed so that hopefully each finishes on time.

Problem Solving

Scrum does not simply focus on developing just any type of end product.  Instead, the Scrum method allows the team to focus on creating a product that fulfils the customer's highest value priorities which are defined by product owners.

Transparency

Transparency among team members and management gives a real momentum to the scrum team. Scrum Master encourages people to ask for help, surface roadblocks, and give public recognition for those brave enough to do so. At the same time, Scrum Master also understands the time wasted and impact on the team when individuals sit on or ignore problems.

Scrum Result

If scrum team follows some of above said soft skills, team velocity will increase significantly.  In turn, customers will appreciate the results or updates – and also can react quickly to any potential problems. Team can deliver high value software features in a short time period keeps everyone on top of changing business conditions.

Tips to be More Innovative in the Age of Agile Testing

What is Agile Testing?
"Agile testing involves testing from the customer perspective as early as possible, testing early and often as code becomes available and stable enough from module/unit level testing." – A wikipedia definition.

The Challenges in Agile Testing

Agile Testers face lot of challenges when they are working with Agile development team. A tester should be able to apply Root-Cause Analysis when finding severe bugs so that they unlikely to reoccur. While Agile has different flavors, Scrum is one process for implementing Agile. Some of the challenging scrum rules to be followed by every individual are

•  Obtain Number of Hours Commitment Up Front
•  Gather Requirements / Estimates Up Front
•  Entering the actual hours and estimated hours daily.
•  Daily Builds
•  Keep the Daily Scrum meetings short
•  Code Inspections are Paramount

So, in order to meet the above challenges, an agile tester needs to be innovative with the tools that they have. A great idea happens when what you have (tangible and intangible) meets the world's deepest hunger

How Testers Can be More Innovative in the Age of Agile Testing?

Here are Important Keys to Innovation:

1. Creative

A good Agile Tester needs to be extremely creative when trying to cope up with speed of development/release.  For a tester, being creative is more important than being critical.

2. Talented

He must be highly talented and strives for more learning and innovating new ideas. Talented Testers are never satisfied with what they have achieved and always strives to find unimaginable bugs of high value and priority.

3. Fearless

An Agile Tester should not be afraid to look at a developer's code and if need be, hopefully in extreme cases, go in and correct it.

4. Visionary

He must have a comprehensive vision, which includes client's expectations and delivery of the good product.

5. Empowered

He must be empowered to work in Pairs.  He will be involving in Pair Programming to bring shorter scripts, better designs and finding more bugs.

6. Passionate

Passionate Testers always have something unique to contribute that may be in terms of their innovative ideas, the way they carry day-to-day work, their outputs and improve things around them tirelessly.

7. Multiple Disciplines

Agile Tester must have multiple skills like, Manual, Functional, Performance testing skills and soft skills like Leadership skills, Communication skills, EI, etc. so that agile testing will become a cake walk.
