Using unit tests

Finding the failure

Note: for this example, we'll use commit 96bcd838.

You build your project and do make check as usual, or you see a failed build in CI. But instead of a success, you get an error:

# make check
 
[...]
 
Test project /builds/mpipz/mgx_private/_build/tests
    Start 1: attributes
    Start 2: cc_index
    Start 3: cc_flips
1/3 Test #2: cc_index .........................   Passed    0.01 sec
2/3 Test #1: attributes .......................   Passed    0.02 sec
3/3 Test #3: cc_flips .........................***Failed    0.02 sec
 
67% tests passed, 1 tests failed out of 3
 
Total Test time (real) =   0.02 sec
 
The following tests FAILED:
                  3 - cc_flips (Failed)

How to test the exact failure?

---

MorphoGraphX tests are named after a pattern. If test is called cc_flips, then test_cc_flips is the name of the CMake target, and the executable is tests/test_cc_flips in the build directory.

# make test_cc_flips
[...]
[100%] Built target test_cc_flips
# ./tests/test_cc_flips
Running 3 test cases...

/home/dcz/Documents/mgx/mgx_private/tests/CCFlips.cpp(156): error: in "flip_class": check !(f5 < f4) has failed

*** 11 failures are detected in the test module "Master Test Suite"

Run your test case in a similar way to find errors.

If you can't find your test case, search for its name inside build files.
