An enterprise can avail several advantages by automating its software testing. Along with beating competition by launching the application early, the customized test automation tools will further optimize its performance by identifying all bugs, errors and flaws. But each organization must consider some additional points to effectuate its test automation strategy. The software testing strategy can be further optimized by adopting test driven development approach.
Under test driven development approach, the automated test cases are written before the coding starts. The test case clearly defines the improvements and new functionality required, while producing the basic code required for passing the test. Based on the initial test results, the new code is refactored to meet the acceptable standards. If you are planning to make a comprehensive automated testing strategy for your project, it is time to understand why you must try test driven development (TDD) approach.
Top 5 Advantages of Test Driven Development Approach
1) Easy to Check Individual Logics
Under this approach, testing is integrated from the granular levels of the software development process. So it becomes easier to check individual and standalone pieces of logic regardless of frequent modifications. As the application needs to be tested thoroughly once the development process is over, loads of new and modified test cases needs to be run to ensure that the application is running flawlessly. The new approach makes it easier to update the legacy applications by incorporating changes in the current software development process. That is why; the TDD approach can be adopted by both young and old organizations to achieve different objectives.
2) Better Options to Streamline Codebase
As automated test cases are written before the coding starts, it becomes easier for an enterprise to get enhanced test coverage without any hassle. The initial refactoring process further helps programmers to write as well as streamline the code base. Also, it becomes easier for developers to maintain the code base without putting any extra effort. They can avoid writing any additional code if test case is not written or use-case is not available for a specific functionality.
3) Create a Clean Interface
Under conventional testing approach, the programmers write code by focusing mainly on the internal working of the application. So they often ignore to check the code from an API-user perspective. But the TDD approach emphasizes on the test case to be written first. So the APIs generated based on these predefined cases are written from the prospective of an API-user. These techniques also result in building an interface that is both clean and economical.
4) Smooth Incorporation of Changes and New Functionalities
The TDD approach prevents the codebase from becoming dated and monolithic through the refactoring process. The process further makes it easier for developers to optimize and strengthen the code base by incorporating changes. As the process is flexible, the programmers can include new functionalities and features by changing the entire architecture of the application. At the same time, they can make the code more efficient by frequently incorporating fresh and innovative ideas without any hassle.
5) Embrace New Technology without Any Hassle
The TDD approach requires the use-cases to be written as test-cases. So the programmers and code writers can observe the test cases to understand the objectives of writing a specific piece of coding. At the same time, unit tests enable developers to adopt and use new technologies by acting as an efficient learning tool. They can simply refer to a small set of predefined unit test, and understand how to address a specific coding bottleneck. Also, the existing codebase can be accessed by new developers to update the application by including new functionalities.
There are always chances that you may have to put some additional time, effort and money to adopt test driven development. But the initial investment will get you higher returns in the long run by delivering rich and flawless user experience.
You can hire automation testers from top software testing companies in India who can help you accomplish testing within allocated budgets and time schedules.
