Invoking the Test Editor

Before invoking the Test Editor, you first need to generate your test classes. Right-Click on the project or the class and select CodePro Tools > Generate Test Cases. For more information, see the section on JUnit Test Case Generation.

The CodePro Test Editor is invoked by Right-clicking the test class and selecting Open With > CodePro Test Editor.

Open With > CodePro Test Editor

Test Editor Pane

By default the Test editor view preference is set to "split with source on left". When you open a test class the source pane is on the left and the test editor pane is one the right. You can change this setting in the CodePro > JUnit > TestEdito preference page.

Split Pane View

Here is a sample of a tabbed pane. You should see a two "notebook like" tabs at the bottom of the editor labeled Source and Tests. Click on the Tests tab to see the test methods in the Test Editor pane.
