Overview

Testing of both CTK widgets and application built on top of CTK could leverage the capabilities offered by the QtTesting library developed by Paraview folks.

If the option CTK_USE_QTTESTING is enabled, the build system will:

• Download external project QtTesting
• Include the event translator and player required for custom CTK widgets. (Located in the same folder as their associated widget sources)
• Include the class ctkEventTranslaterPlayerWidget into CTKWidgets library
• If BUILD_TESTING is enabled: CTK widgets EventTranslatorTests will be compiled. These tests will use ctkEventTranslaterPlayerWidget and ensure that events associated with CTK widgets can be properly recorded and played.

Note: Option CTK_USE_QTTESTING will be automatically enabled if BUILD_TESTING is ON

Milestones

1. Integration: What and where.
2. Integrate QtTesting has an external projects
3. Implement ctkEventTranslaterPlayerWidget
4. Create custom translator/player if needed
5. Implement widgets EventTranslatorTests
