Best Practices for QA Testing | Global App Testing (2024)

Incorporating agile methodologies into software testing

Adopting a methodology that incorporates testing into a series of short development cycles is another best QA practice worth considering.

Agile methodologies make sense in the context of developing mobile apps, given that these products typically have short development cycles and mobile users have extremely high expectations regarding functionality, quality and frequent updates.

Best Practices for QA Testing | Global App Testing (1)

With agile methodologies, QA testing is part of the design and development processes, rather than being a separate phase. Test results are directly incorporated into the design and development processes, and quality becomes a guiding principle.

This is a collaborative approach that requires designers, developers, the QA team, and sometimes even users to communicate or work together. In order to facilitate collaboration, you can use a single repository for the app code.

Your teams will go through a short design or development cycle, followed by a targeted quality control and testing phase for the new feature that was just added. Additional regression testing, security testing, and stress testing can be undertaken as needed. The outcome of this phase will determine what happens during the next design or development cycle.

Leveraging automation will keep things moving once you adopt this approach. Test automation speeds up the targeted testing phases and helps you to move onto the next development cycle in a matter of hours or days. You will need to schedule manual tests after some key design or development cycles to incorporate feedback regarding the user experience and other key aspects of the app.

You will need to create a framework for reviewing and using the data generated during the short testing phases. It’s not enough to simply undergo functional testing - you need to incorporate feedback into the design and development process as early as possible.

Writing good test cases

Should developers write tests? On one hand, the agile approach is about ownership. Involving developers in the test case writing process will make QA one of their responsibilities.

On the other hand, developers who create tests might become biased and write code that will pass the test without meeting other quality standards, or unconsciously create a test with limited coverage.

For this reason, some teams create a test plan but then rely on outsourcing the process, or handing it over to dedicated QA engineers.

Even though each test case should have a narrow focus, there should be cohesion in your test case suite. Your test case suite should have a scope that is adapted to the scale of your project.

Customise and execute test cases in an environment that is different to the one used for development. Each test should be based on clear expectations and result in a measurable outcome.

Break down each test case into a series of concise steps. Taking these steps will tell you whether or not a feature works. You can think of writing a test case as a series of actions associated with a question. When an action is taken, the automated test or human testers should answer a simple question to measure the success of the action.

The instructions written for each test case should give testers a clear understanding of what they are expected to do. You can save time and get better results by providing test cases, instructions, and tutorials that aren’t liable to misinterpretation. There are testing tools available to make this even easier.

Continuous integration and continuous delivery

Continuous integration (CI) and continuous delivery (CD) are strategies used in software development that complement the agile methodology. You can incorporate a continuous testing strategy to CI and CD.

Best Practices for QA Testing | Global App Testing (4)Continous integration

Without CI and CD, developers split up their work and assemble different segments of the code late in the development cycle. This can result in a lack of cohesion, compatibility, and issues with how the different segments of the code interact.

With continuous integration, the code is kept in a central repository. Developers work on making small changes to the code and upload small sections of code to the central repository regularly. You can incorporate quality management into this methodology by having a series of tests performed every time the code is updated. The new segments need to be tested, but you should also conduct regression testing to see how changes affect the main features of the product.

Continuous delivery allows you to release new iterations of your product on a regular basis. This is a quick and efficient approach to addressing bugs and issues that affect the user experience.

The key is to incorporate user feedback into your CI and CD processes so that issues can be quickly addressed and a new and improved version of your product can be released.

Again, you will have to incorporate testing in your process, for instance by having crowd testers perform usability tests before a new major version of your product is made available to users.

Software QA testing best practices:

  1. Test one thing at a time: tests should have clear objectives. Each test should focus on a feature or look at things like user interface or security.

  2. Understand the types of testing on offer: there are lots of different types of tests - from load testing to user acceptance testing (UAT) - so make sure you understand the differences and how to use them.

  3. Use regression tests: testing a main feature once isn’t enough. New additions to the code repository can interfere with features that previously passed tests.

  4. Report and track bugs: determine how bugs will be reported and what kind of data is needed. Will you use an open-source bug tracking tool, or build one that’s specifically suited to your workflow?

  5. Leverage analytics: decide which QA metrics to track. Keep records of every test conducted and use this data to determine where bugs are likely to occur. This data will help you to develop new tests that address problem areas.

  6. Choose the right environment for tests: try covering a wide range of scenarios, including different devices, OS and user profiles.

  7. Use unit and integration tests: unit testing will isolate each component of your app, while integration tests will assess how well each subsystem works. Run unit tests in parallel to save time, but don't move onto integration tests until you have ensured that individual components work like they should.

  8. Don’t neglect the UI: use functional tests performed by human testers to perform end-to-end scenarios and get a feel for the UI of the app. It might be best to wait until you have fixed issues detected during unit and integration tests.

Achieving high quality and speed

Whether you’re building a web application, downloadable software, or an API, high quality and speed should be key objectives. Your QA testing process is a process you will have to regularly review for efficiency as you move through the different cycles of your project.

You can achieve high quality by creating a framework and best practices for writing and implementing tests.

The code used for automated tests should be also tested, and the written tests sent to human quality assurance testers should be carefully reviewed. Make it easy for everyone involved with your project to report bugs and share feedback.

You also need to focus on efficiency. Using an off-the-shelf bug tracker like Jira is the best way to keep track of quality issues and to make sure they are addressed in a satisfactory and timely manner.

Maintaining a list of clear quality objectives is crucial for achieving speed and high quality. Align your quality objectives with users’ expectations and use these objectives when writing test cases. You should also take into account the ISO 9000 quality management standard, as well as your stakeholders needs.

Working with a clear set of quality objectives will help developers, testers, and designers to get a better understanding of what is expected of them and foster an environment where everyone owns quality.

QA testing methodologies

Test-Driven development

Test-Driven Development (TDD) is an iterative software development approach that emphasizes writing automated tests before writing the actual production code. The TDD process typically follows these steps: writing a failing test, writing the minimum code required to pass the test, refactoring the code, and then repeating the cycle. Here's a more detailed breakdown:

TDD offers several benefits:

Design Improvement: TDD encourages developers to focus on writing modular, loosely coupled, and easily testable code. The frequent refactoring step helps improve the overall design and maintainability of the codebase.

Faster Feedback Loop: TDD allows for rapid feedback on code changes. Developers know immediately if a change breaks existing functionality, enabling them to identify and fix issues early in the development cycle.

Reduced Debugging Time: Since issues are caught early in the development process, debugging time is reduced. Bugs are typically isolated to the recent changes, making them easier to identify and fix.

QA and Crowdtesting

Crowdtesting is another element of the QA puzzle. This approach helps you to save a considerable amount of time and will unlock new possibilities if you have been limited in the depth and scope of your testing.

Crowdtesting allows you to conduct tests on a much larger scale. You can have thousands of QA testers on a wide range of devices, operating systems, and networks, meaning they can cover different scenarios, find more bugs, and complete tests within a matter of hours.

Start by rethinking the way team members work, for instance by adopting the agile methodology or making CI and CD the core elements of your workflow. You should also combine different testing methods, including in-house testing, automated testing, and crowdtesting.

❝ These three testing methods will help you to save time and cover a much wider scope.❞

The tests themselves should be improved, such as by narrowing the focus of each test and having a set of clear objectives. You can improve your QA testing process and achieve speed and high quality by adopting a few key strategies.

Lastly, your QA strategy should be unique to the product you are developing and it’s lifecycle. It should be aligned with the scope of the project, your definition of quality, and end users’ expectations.

Traditionally, TDD is associated with automated software tests

  1. Test Design and Review: During the initial test design phase of TDD, crowdtesting can be leveraged to gather input and insights from a diverse group of professional testers. Testers from the crowd can provide valuable perspectives, identify potential edge cases, and suggest improvements to the test design. This collaborative approach helps refine the test coverage and ensures a more comprehensive suite of tests.

  2. Test Execution and Validation: After writing the initial failing test case in TDD, crowdtesting can be employed to execute the tests and validate the behavior of the code. Crowdsourced testers can run the tests on various devices, platforms, and configurations, providing broader coverage and detecting issues that may not have been anticipated during the initial design. Their feedback helps validate the correctness and reliability of the code.

  3. Exploratory Testing: Crowdtesting, known for its exploratory nature, can be particularly beneficial during the refactoring phase of TDD. While refactoring aims to improve code structure without changing functionality, it can introduce unforeseen bugs. Crowdtesters can perform exploratory testing without scripts or predefined steps to uncover any regression or compatibility issues caused by refactoring, providing additional confidence in the code's stability.

  4. Feedback and Iteration: Crowdtesting can also contribute to the iterative nature of TDD. Testers from the crowd can provide valuable feedback, bug reports, and suggestions for improvement during each iteration. Their diverse perspectives and experiences can identify blind spots and help refine the codebase, ensuring higher quality and better user experiences.

Developing your own QA testing strategies

The right QA testing methodology will provide the information needed by your design and development teams to produce a quality app. Remember that software quality doesn't depend on testing but on the outcome of your QA tests and how you use this data.

Your approach to QA testing needs to be adapted to the product you are developing.
