Question

JUnit test files are written in files with which file extension?

(b) .test

(c) .java

(d) .unit

I got this question by my school principal while I was bunking the class.

Question is from Exploring Core JUnit topic in section Exploring Core JUnit of JUnit

Answer 1

Correct option is (c) .java

The best I can explain: JUnit test files are regular java files with special methods which are referenced via annotations.
