Performing TDD on Mobile Test Automation

14 April 2022

As we are witnessing advancement on the technological front, testing has become much more than a mere support function. Hence, organizations are developing software with a quality-centric approach. Out of the many test automation methods used by organizations to maintain the high quality of the software, TDD is one of the prominent methods. Test-Driven Development otherwise known as TDD is a testing approach in which tests are written even before completing the production; the purpose of introducing tests early is to understand the requirement before writing full-fledged codes.

Implementing TDD is a critical task that involves the testers and developers to understand how the application’s feature will be used in real-world scenario, and offer seamless experience to the users. TDD is a sequential process in which testing is carried out on all the units of the application in a gradual way, ensuring the application has been tested throughout the workflow.

The TDD method is chosen to evaluate the code; here, test cases for a new function are tested, in the event of code failure, new codes are written. This approach makes sure only successful codes are written, and ensures that the final codes being used emerge as quality codes without being buggy. Testing codes for success or failure and writing new codes only in case the existing code fails allows the developers to create unique codes without duplication. TDD framework is used by the organizations to create top-quality applications; let us understand more on the TDD approach in this article.

Everything to know about TDD

To leverage the best out of TDD, one should thoroughly understand it and execute accordingly. It is the process which allows testing to manage the development process. TDD has been implemented by organizations for the wide range of benefits it offers. Some of the advantages on implementing TTD are as follows:

Understanding the requirements: As the tests are written before the production codes in TDD, it gives immense scope to the developers to understand the requirements and write the codes accordingly. Once the requirements are understood completely, the outcome will shape up as expected.

High test coverage: In TDD approach, testing is being conducted to every unit even before the actual production codes are written. This results in more test which further increases the test coverage for the code. Higher test coverage helps in minimizing errors and creating applications of high-quality.

Improves development process: As TDD improves the QA process and detects error at an early stage, it offers scope to the developers to speed up the development by reducing time spent on debugging. It improves the whole development process by reducing the number of reworks, quickly fix the fewer errors, and streamlining the process.

Reduced development time: TDD ensures that the codes written are correct without any discrepancy; hence, reducing the number of revisits and reworks. The whole process speeds up development and reduces the time taken to develop the application.

High code quality: TDD allows the creation of simple, quality codes. The codes are developed after the initial testing is conducted, allowing the developers to design the workflow and create codes accordingly. This process helps in creating quality codes that will, in turn, create apps of excellent quality.

Improve application quality: In TDD approach, testing is carried out even before the production codes are written to design the workflow. It is a more streamlined process compared to the conventional testing method; as a result, the occurrence of errors is drastically reduced, increasing the quality of the application. The TDD approach, thereby, helps in creating apps of high-quality that in turn offers seamless customer experience, attracts new users, and builds brand reputation.

Steps involved in performing TDD

TDD involves writing a huge number of tests that will help in reducing the number of bugs occurring. To ensure the TDD process is performed to yield the maximum benefits, the following steps should be implemented:

Writing test: Writing test is one of the important aspects to perform testing. For testing of new feature or implementing changes, quality tests must be written to ensure the best outcomes are obtained. Hence, the first major step in implementing TDD is writing tests.

Run test: Once the test is written, it has to be Run to check if it passes or fails. Ideally, the Run should fail as the production codes will be written based on the test.

Writing code to pass the test: As the test has failed in the Run stage, now the correct code has to be written to ensure the test passes this time.

Re-run the test: Once the codes have been written to pass the failed tests, the test is Run again to check for its success or failure. This time, the test should pass.

Minor changes: Once the test has passed, any required modifications are done to stabilize the code and ensure it doesn’t break.

Companies implementing TDD ensure these steps are involved to streamline the process and come up with top-quality end products that will offer complete customer satisfaction.

Conclusion

Organizations are adopting TDD to write quality codes with reduced time and effort. Today, TDD is one of the most preferred methods to improve the quality of an application, and companies are actively implementing TDD frameworks as a part of their growth strategy. It is one of the most efficient methods to improve quality, speed up development, reduce time-to-market, and save cost.
