ON employee[emp_id, emp_name,dept_id]

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).
