Testing

From VDrift
Jump to: navigation, search

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

Contents

Running the Tests

To run unit tests, the test executable must first be built.

Building

In the VDrift source root, run:

scons test

Executing

The executable is called vdrift-test and is compiled to the build/ directory in the root of the VDrift source tree. To run it, simply do:

build/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.
