How To Write a JUnit Test Method?
This interview question is to check if you know the basic rules about writing a JUnit test method:
- You need to mark the method as a JUnit test method with the JUnit annotation: @org.junit.Test.
- A JUnit test method must be a "public" method. This allows the runner class to access this method.
- A JUnit test method must be a "void" method. The runner class does not check any return values.
- A JUnit test should perform one JUnit assertion - calling an org.junit.Assert.assertXXX() method.
Here is a simple JUnit test method:
import org.junit.*;
// by FYICenter.com
...
@Test public void testHello() {
String message = "Hello World!";
Assert.assertEquals(12, message.length());
}
