A test strategy is a high-level document outlining how you plan to test the system. It's important to have a clear and concise test strategy to ensure that your testing is effective and efficient. A good test strategy will cover all areas of the system, including:

Here are few resources that I would recommend to learn about creating an effective testing strategy:

5. Risk Analysis

Risk analysis is the process of identifying and assessing potential risks to the system being tested. It's essential to perform risk analysis at the beginning of the testing process, and to revisit it regularly throughout the testing cycle. Risks can be technical, functional, or business-related. A thorough risk analysis can help you prioritize your testing efforts and focus on areas of the system that are most at risk.

Here are few resources that I would recommend to learn risk analysis in depth:

Here are a couple of resources that I would recommend to learn about biases in depth:

7. Exploring Requirements

Exploring requirements is an essential part of any testing project. It’s important to explore the different layers of requirements and not just limit yourself to the written requirements. Here are four activities that can help you explore requirements well:

Here are a couple of resources that I would recommend to learn about exploring requirements in depth:

To conclude, these 7 testing topics may not be discussed as often as they should be, but they can significantly impact the quality of your testing efforts. You can level up your testing game and test effectively by focusing on test design, diverse and combined test data, test environment setup and cleanup, test strategy, risk analysis, biases, and exploring requirements. As a professional, it's essential to evaluate and improve your testing efforts continuously, and these topics can provide valuable insights to do just that.

Use Generative AI for Data Driven Test

By creating a vast quantity of diverse test data that may be utilised to assess software systems, generative AI can be employed for data-driven testing strategies. This method can aid in the identification of edge cases and the discovery of previously unknown issues that would not have been detected by manually generated test data.

Let’s take an example with chatGPT to create test data for testing an application form which has fields like First Name, Last Name, Phone Number.

Prompt Example:

You have been assigned to generate test data for the following fields in a software application: First Name, Last Name, Phone Number in table format. Some of these fields have specific requirements and validations. Your task is to design a set of test data that covers various scenarios, including valid inputs, boundary values, and potential errors.

As shown above the given prompt generated a comprehensive set of test data that can be readily utilized for testing purposes. Additionally, you have the flexibility to choose the format of the test data, such as JSON, for consumption in API Automation frameworks. If you require the output in JSON format, you can include this preference in the prompt.

Conclusion:

As the renowned software testing expert William E. Lewis once said, "Effective testing requires both the cleverness of the human mind and the precision of machines." Creating a successful data-driven test strategy involves meticulous planning and execution. By adhering to the following guidelines, you can guarantee that your testing endeavours are exhaustive, impactful, and aligned with your project objectives and timeline.

The crucial aspects include identifying appropriate test scenarios, defining relevant test data, developing data-driven test scripts, prioritising test cases, analyzing test outcomes, and consistently iterating and enhancing your testing practices. By implementing these steps, you can be confident that your applications are rigorously tested, and any defects or glitches are identified and resolved before affecting the end-users.

Test Pyramid: Then and Now

It's crucial to keep in mind that the technology landscape is constantly changing, and novel trends and inventions appear frequently. To keep up with these every changing trends, test engineering and test practices should evolve accordingly. Revisiting the test pyramid, slicing each layer one at a time.

Unit Tests

Even more so than before, this is still true for the current scenarios. It makes more sense than ever to have as many complex unit tests as possible, especially as more and more companies use microservice design. The co-creation model leading to integration with outside apps just adds up to another factor. These integration operations ought to be airtight, sealing the bugleaks. I agree with Mike Cohn about finding bugs at its source and strengthening the Foundational elements.

Integration Tests

Two decades ago, the scope of integration tests was solely verifying the interaction between different software components or modules. From a testing perspective, the challenge was to develop custom test harnesses and scripts to simulate the interactions between components and validate their integration. Mocking/simulation of dependencies was not as prevalent. In the present scenario, integration tests encompass a broader scope due to the complex and distributed nature of software systems. The validations are for the software components and across various services, APIs, and external dependencies. There are powerful tools for designing, executing, and managing integration tests in the present scenario.

Integration testing is now more effective and repeatable thanks to containerization technologies like Docker and virtualization technologies like virtual machines that have made it simpler to develop and manage isolated test environments. With the rise of microservices architecture, API testing and contract testing have gained prominence.

Integration tests are equally important in the present technological landscape as unit tests aim to test an application from several other parameters. I believe that integration tests are equally important covering multiple aspects of an application and not just focusing on application functionality.

Frontend/UI

Regarding front-end test automation, the unanimous agreement is flaky, and I am not contesting against that. However, frontend testing (UI testing) has undergone tremendous changes and technological advancements. Two decades ago, the whole purpose of a frontend was to provide a touchpoint for a customer, creating an opportunity for them to interact with the application. The internet also wasn’t mature enough. However fast forward 20 years, today front end development is an ocean in itself.

The Internet is stronger than before, offering multiple application optimization options. Today, all businesses are more towards user centric designs, making every touchpoint of an application to be a great experience no matter the device or location used to interact. Whether a B2B or a B2C application, user experience will be at the heart of development. As we are growing to be digitally inclined, organizations are taking a stand towards digital inclusion where Accessibility guidelines become mandatory routine. Thanks to many country laws for enforcing this as compliance.

In today’s game of the internet, frontend development directly affects SEO by influencing website structure, performance, mobile-friendliness, user experience, and content optimization. There is a need to accommodate multifold layers of tests when it comes to the frontend, and is no longer restricted to functional checks. In my perspective, UI tests are as important as unit and integration tests.

I believe the test structure moved from the Pyramid to the Sandwich structure.

Conclusion

Although we can't entirely dismiss the test pyramid, Even while we can't completely discount the test pyramid, it fits if the test automation plan is developed from the end user's standpoint. However, the complexity of testing all aspects of an application has grown today. Technical, user, functional, and last but not least, how well the application functions online to keep up with its SEO score.
