Generating JUnit stubs for new methods in existing class in Eclipse

Question

This question is tangentially related to How can I create JUnit stub methods in eclipse? but it doesn\'t answer my specific question.

Assuming you have an existing JUnit

Answer 1

The usual working cycle with unit tests is to create the test case first

public void test_new_method() {
    ClassUnderTest x = new ClassUnderTest();
    x.NewMethod();
}

At that point Eclipse will give you a warning that the method "NewMethod" does not exist. Than you simply select a "Quick Fix" (Ctrl-1 or Ctrl-2 i'm not sure) to create the missing method in the class.

Answer 2

1. Install the MoreUnit extension from the MarketPlace.
2. Open the package hierarchy panel.
3. Navigate down to the class that you've modified.
4. Right click on the new method.
5. Select "Generate Test". The generated stub will appear in your ClassTest file.

Answer 3

My solution.

I simply go through the standard 'create JUnit test case'

Select file to test. -> New Junit test case

Go through the normal process in creating the test case, but only select those that you want new stubs for.

The file is created with the stubs, which I now copy into the existing test case file. Delete the newly created test file class.

It's not the most efficient, but quicker than 'thick fingering' when you create them manually.
