For me TDD is Test-Driven Development, not Unit Test-Driven Development. So my TDD practice combines unit tests, integration tests, functional and acceptance tests. This results in some components being covered by certain types of tests and others components being covered by other types of tests in a very pragmatic fashion.
There are two types of regression: functional and non-functional. In functional regression, there is a loss of functionality. In other words, when one aspect of the software is changed, some other aspect stops working. In non-functional regression, the software’s functionality works as intended, but the system might now be suffering fromIt is performed by test engineers only. 5. Integration testing is performed by developers as well test engineers. 6. Here the testing is performed on the system as a whole including all the external interfaces, so any defect found in it is regarded as defect of whole system. 6.
Read here – all about Functional Testing vs Integration Testing. The Testing Process in Functional Testing Vs Regression Testing: Functional Testing. The process of Functional Testing involves: Identifying the functionality to be tested. Raising data requests if necessary. Running test cases. Comparing the output with the expected outcome.
Testing is essential to improve software quality and minimize errors. Tests are an essential requirement for good refactoring. There are different tests, e.g., Unit Tests, Integration, Functional, and Acceptance Tests. The basic structure of tests is arrange, act, and assert. Mocking is used to free methods from their dependencies during unit
