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