Does Junit reinitialize the class with each test method invocation?

Question

When i run the below code, both test cases come true:

import static junit.framework.Assert.assertEquals;

import org.junit.Test;

public class MyTest{
    pr         


        

Answer 1

Look at the documentation of org.junit.runner.Runner:

The default runner implementation guarantees that the instances of the test case class will be constructed immediately before running the test and that the runner will retain no reference to the test case instances, generally making them available for garbage collection.

Unit tests should be independant otherwise it becomes unmaintable. Note that the order of executed methods is not guaranteed (unless you use the annotation @FixMethodOrder).
