Self Tests

FAQ

Frequently asked questions about how to write and execute tests for Slicer.

How are the tests executed ?

There are two main mechanisms:

• On-demand execution using:

  • Reload & Test module panel section displayed for scripted modules when the developer mode is enabled in the application settings.

  • Self Tests module user interface.

• Automatic execution using:

  • CTest in the context of Nightly tests.

How are the tests discovered ?

To be discovered, scripted modules are expected to have the following:

• implement a test case class named <ModuleName>Test (itself deriving from slicer.ScriptedLoadableModule.ScriptedLoadableModuleTest).

• provide a function called runTest().

These will ensure that the runTest() function is always discovered and executed.

Note

Scripted modules generated using the Extension Wizard already implement the expected test case.
