QtTest
|
|
----------
|
|
|
|
This module defines functions to help use the Qt Test infrastructure.
|
|
The main function is :command:`qtest_discover_tests`.
|
|
|
|
.. command:: qtest_discover_tests
|
|
|
|
Automatically add tests with CTest by querying the compiled test executable
|
|
for available tests::
|
|
|
|
qtest_discover_tests(target
|
|
[WORKING_DIRECTORY dir]
|
|
[TEST_PREFIX prefix]
|
|
[TEST_SUFFIX suffix]
|
|
[PROPERTIES name1 value1...]
|
|
[DISCOVERY_TIMEOUT seconds])
|
|
|
|
``qtest_discover_tests`` sets up a post-build command on the test executable
|
|
that generates the list of tests by parsing the output from running the test
|
|
with the ``-datatags`` argument. This ensures that the full list of
|
|
tests, including instantiations of parameterized tests, is obtained. Since
|
|
test discovery occurs at build time, it is not necessary to re-run CMake when
|
|
the list of tests changes.
|
|
|
|
The options are:
|
|
|
|
``target``
|
|
Specifies the Google Test executable, which must be a known CMake
|
|
executable target. CMake will substitute the location of the built
|
|
executable when running the test.
|
|
|
|
``WORKING_DIRECTORY dir``
|
|
Specifies the directory in which to run the discovered test cases. If this
|
|
option is not provided, the current binary directory is used.
|
|
|
|
``TEST_PREFIX prefix``
|
|
Specifies a ``prefix`` to be prepended to the name of each discovered test
|
|
case.
|
|
|
|
``TEST_SUFFIX suffix``
|
|
Similar to ``TEST_PREFIX`` except the ``suffix`` is appended to the name of
|
|
every discovered test case. Both ``TEST_PREFIX`` and ``TEST_SUFFIX`` may
|
|
be specified.
|
|
|
|
``PROPERTIES name1 value1...``
|
|
Specifies additional properties to be set on all tests discovered by this
|
|
invocation of ``qtest_discover_tests``. You can specify a timeout for the
|
|
test execution by setting the TIMEOUT property here, as supported by ctest.
|
|
|
|
``DISCOVERY_TIMEOUT sec``
|
|
Specifies how long (in seconds) CMake will wait for the test to enumerate
|
|
available tests. If the test takes longer than this, discovery (and your
|
|
build) will fail. Most test executables will enumerate their tests very
|
|
quickly, but under some exceptional circumstances, a test may require a
|
|
longer timeout. The default is 5. See also the ``TIMEOUT`` option of
|
|
:command:`execute_process`.
