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

Issues finded on QtTesting

• QSpinBox/QDoubleSpinBox :
  • A long click on the up/down arrow -> just one click even if the value change severals times
  • Fast click -> Double click -> no effect.

• In pq3DView :
  • The scroll button has no effect - Implemented for ctk

• QComboBox when it is editable :
  • The hight-event "set_sting" crash if we edit the comboBox. Exemple if we have an item "foo", we are goning ti edit the comboBox with "f", but the item "f" doesn't exist, so the event crash.
