• Do you frequently copy-paste exisiting unit tests to test a recurrent specification?
• Do you frequently copy-paste existing documentation fragments to document a recurrent specification?
• Do you find it annoying to update both the corresponding unit tests AND documentation fragments when a specification evolves?

If you answered yes to any of the above questions, then DScribe is the right tool for you!

DScribe allows you to test and document recurring concerns consistently and with ease. You simply define joint templates to capture the structure to test and document a specification. Then, you use method-level Java annotations to invoke the templates.

To learn more about DScribe, visit the DScribe GitHub repository.

Running DScribe in Eclipse
To generate unit tests and documentation for a production class(es):

1. Select the target class(es) in Eclipse's Project Explorer view.
   • To select one class, simply click on it with your mouse.
   • To select multiple classes, hold down the Ctrl key and click on each class one by one.
2. Perform a Right click. The Eclipse dropdown menu will appear.
3. Click the Run DScribe command in the dropdown menu (see screenshot).

Once DScribe terminates, a message dialog will appear to display the execution results. If DScribe runs successfully, the generated documentation and unit tests will be added to the production class and its corresponding test class, respectively.
