TDD is an acronym for Test-Driven Development. TDD is a software development process that relies on the repetition of a very short development cycle: first the developer writes an (initially failing) automated test case that defines a desired improvement or new function, then produces the minimum amount of code to pass that test.

TDD is an iterative software development process where you first write the test with the idea that it must fail.

This is a different approach to the traditional development where you write the application functionality first andthen write test cases. The major benefit of this approach is that the code becomes thoroughly unit tested (you canuse JUnit or other unit testing frameworks).

When responding to conflict resolution questions, answer with confidence since you're being considered for a supervisory position where you will frequently be required to work in teams, delegate responsibilities, and handle difficult problems.

In other words, employees must be situated around others they can work with so productivity is not affected.

Regression Testing: When changes in the code of the software are made to fix the previous bug. Then testing needs to be perform to ensure that it will not generate a new bug in the application and it works as specified and that it has not negatively impacted any functionality that it offered previously. Regression Testing is important because of following reason:

- That the application works even after the alteration in the code were made.

- The original functionality continues to work as specified even after doing changes in the software application.

- The alteration to the software application has not introduced any new bugs.
