Test-driven development (TDD) is a way of writing code that involves writing an automated unit-level test case that fails, then writing just enough code to make the test pass, then refactoring both the test code and the production code, then repeating with another new test case.
Mockito is an open source testing framework for Java released under the MIT License. [3] [4] The framework allows the creation of test double objects (mock objects) in automated unit tests for the purpose of test-driven development (TDD) or behavior-driven development (BDD). The framework's name and logo are a play on mojitos, a type of drink.
Programmers working with the test-driven development (TDD) method make use of mock objects when writing software. Mock objects meet the interface requirements of, and stand in for, more complex real ones; thus they allow programmers to write and unit-test functionality in one area without calling complex underlying or collaborating classes.

The Transformation Priority Premise is a name given to the mental structure TDD’ers build up over time as to balance your code from being too specific, rather than generic. The idea is that with each example you add to the tests you move up the Transformation Priority list, making your code more generic, so able to handle more of the cases.
Never write a single line of code unless you have a failing automated test. Eliminate duplication. The book illustrates the use of unit testing as part of the methodology, including examples in Java and Python. One section includes using test-driven development to develop a unit testing framework. 2003.
The concept is generally invoked facetiously, and comes with the implication that high volumes of computer code are written with little regard for unit testing by the programmers. The term itself is a tongue-in-cheek reference to test-driven development, a widely used methodology in agile software practices. In test-driven development tests are ...
If the test does not fail, the programmers should determine whether there is a bug in the test code, or that the production code does support the functionality described by the new test. Write code: The programmers write just enough production code so the new test will pass. Run test: The unit tests are executed to verify that the new ...
