What is TDD (Test Driven Development) ?

What is the significance of TDD?

TDD is also known as a Test-Driven Development service that is destined to write tests for developing creative and innovative software. The TDD is executed before the implementation of the minimum coding efforts for fulfillment. After the tests are written, the codes will be altered and modified according to the needs to complete the testing procedure. Every functionality of the software will be tested under the same procedure. Here, you will know the details about how to perform the TDD test, along with its illustrations and clarifications.

Test-Driven Development starts with designing and developing tests for every small functionality of an application. In the TDD approach, first, the test is developed which specifies and validates what the code will do.

How to perform TDD Test:

Learn the Illustration or process of TDD

TDD follows a certain sequence for executing the test procedure. The illustration for the test process goes as follows:

1. The test is written in the first step.

2. The next step demands the running of the written test.

3. Failure tests will be identified.

4. Changes will be made to the code, If necessary.

5. After making the changes, the test will run again, and the process will repeat until the test passes with zero errors.

Detailed Clarification about the TDD 

1. For a clear idea, TDD does not involve the process of software testing or design. It tests the code before it is implemented on the application.

2.TDD does not follow the algorithm of preparing the test and finding a system to execute those tests successfully.

3. TDD does not support rigorous testing.

As stated in the first point, TDD is designated as the process of running the test code before the implementation of the same on the real application development process.

Advantage of TDD over other processes

In the process of TDD, the coding is given the utmost priority on them first-hand. Here, you will be writing the codes for the functionality that does not exist at all. You are most likely sure to find faults at the first trial that will lead you to make minor corrections at all stages to get the desired output much faster than the usual approaches. In other processes, the application is first developed after which the test is performed, and the errors are identified that require code alteration. It is a long process full of hassles. Therefore, TDD makes sure that you catch all the loopholes in your code before the development process completes it.

Know the benefits of TDD

All the software development practices are experiencing rewarding benefits by using TDD:

1. TDD will help automate the tests to save time and efforts over manual testing methods.

2. TDD will run tests after each bug fix to make sure that there are no bugs at the end of the development process.

3. TDD reduces the time taken for the regression testing of the application.

4. TDD ensures high-quality application coding.

5. There is a minimum need of coding alteration with the implementation of the TDD process.
