VDrift includes a very simple unit testing framework for C++ code. It is derived from QuickTest.

Running the Tests

Unit tests are compiled by default. To execute run:

  • Ubuntu: build/vdrift -test
  • macOS: build/vdrift.app/Contents/MacOS/vdrift -test

Results

The results are written to STDOUT. An example:

[-------------- RUNNING UNIT TESTS --------------]
src/matrix4.cpp(26): 'matrix4_test' FAILED: value1 (1) should be close to value2 (0)
src/matrix4.cpp(27): 'matrix4_test' FAILED: value1 (10) should be close to value2 (20)
src/matrix4.cpp(28): 'matrix4_test' FAILED: value1 (-1.19209e-07) should be close to value2 (-1)
src/matrix4.cpp(33): 'matrix4_test' FAILED: value1 (1) should be close to value2 (0)
src/matrix4.cpp(34): 'matrix4_test' FAILED: value1 (10) should be close to value2 (0)
src/matrix4.cpp(35): 'matrix4_test' FAILED: value1 (-1.19209e-07) should be close to value2 (1)
Results: 29 succeeded, 1 failed
[-------------- UNIT TESTS FINISHED -------------]

Writing New Tests

Consult the QuickTest How to Use It and the QuickTest API Reference for details on how to write unit tests using QuickTest.

Example Tests

To look at some example test code already in VDrift, look at src/*.cpp files which contain the macro QT_TEST.
