Extreme Programming involves − Writing unit tests before programming and keeping all of the tests running at all times. Write failing automated test -> Run failing test -> develop code to make test pass -> run test -> repeat. The focus is on well‐known test methods, especially black box and white box methods, and on how testing is performed – and could be performed – in XP. The Test-Driven Development process. Extreme Programming Practices XP suggests using 12 practices while developing software. Quadrant 1 is the Unit and the components test that can be automated with the TDD approach.. Quadrant 2 talks about the functionality testing, where we can apply the BDD approach.. Quadrant 3 is the only quadrant which has a scope of manual testing.. Quadrant 4 basically talks about the testing that can be achieved by some tools. The benefit of manual testing is that it allows a human mind to draw insights from a test that might otherwise be missed by an automated testing program. XP is more than just a series of steps to manage projects—it follows a set of values that will help your team work faster and collaborate more effectively. Software development in the 1990s was shaped by two major influences: internally, object-oriented programming replaced procedural programming as the programming paradigm favored by some in the industry; externally, the rise of the Internet and the dot-com boom emphasized speed-to-market and company-growth as competitive business factors.
