Test Driven Development (TDD) is a paradigm for writing minimal code to pass a pre-defined test or tests. Test-driven development starts with developing a test for each one of the features. The test might fail as the tests are developed even before the development and the development team then develops and refactors the code to pass the test. Test-driven development is related to the test-first approach theory evolved as part of extreme programming concepts.
TestNG
TestNG is a testing framework that is inspired by JUnit and NUnit but introducing some new functionalities that make it more powerful and easy to use. TestNG is an open-source advanced automated testing framework designed in a way to leverage the benefits by both the developers and testers. This eliminates most of the limitations of the older framework. It provides the developer the ability to write more flexible and powerful tests with help of easy annotations, grouping, sequencing & parametrizing.
TDD Process Steps
A successful testing strategy needs to look at the whole cycle of what you are creating and releasing. Following a test-driven approach to make sure developers are checking in high-quality code is a good place to start and will ensure better results down the road.
TDD process flow chart
Test Driven Development Key features
- It promotes confirmatory testing of the application code and is briefly specified.
- Both acceptance test (detailed requirements) and developer tests (unit test) are inputs for TDD.
- TDD makes the code clear & simple which allows the developer to maintain less documentation.
- TDD shortens the programming feedback loop.
- TDD promotes the development of high-quality code
Benefits of using Test Driven Development
- The developer must understand first, what the desired result should be and how to test it before creating the code.
- The code for a component is completed only when the test passes and the code is refactored. This ensures testing and refactoring before the developer moves on to the next test.
As a set of Unit tests is run after each refactoring, feedback that each of the components is still working in constant. - The Unit tests act as living documentation that is always up to the data.
If a defect is found, the developer creates a test to reveal that defect and then modify the code so that the test passes and the defect is fixed. This reduces debugging time. All the other tests are also run and when they pass, it ensures that the existing functionality is not broken. - The developer can make design decisions and refactor at any time and the running of the tests ensures that the system is still working. This makes the software maintainable.
- On each successive test run, all the previous defect fixes are also verified and the repetition of the same defect is reduced.
- As most of the testing is done during the development itself, the testing before delivery is shortened.
