add_testΒΆ

Add a test to the project to be run by ctest(1).

add_test(NAME <name> COMMAND <command> [<arg>...]
         [CONFIGURATIONS <config>...]
         [WORKING_DIRECTORY <dir>]
         [COMMAND_EXPAND_LISTS])

Adds a test called <name>. The test name may contain arbitrary characters, expressed as a Quoted Argument or Bracket Argument if necessary. See policy CMP0110. The options are:

COMMAND

Specify the test command-line. If <command> specifies an executable target (created by add_executable()) it will automatically be replaced by the location of the executable created at build time.

The command may be specified using generator expressions.

CONFIGURATIONS

Restrict execution of the test only to the named configurations.

WORKING_DIRECTORY

Set the WORKING_DIRECTORY test property to specify the working directory in which to execute the test. If not specified the test will be run with the current working directory set to the build directory corresponding to the current source directory.

The working directory may be specified using generator expressions.

COMMAND_EXPAND_LISTS

New in version 3.16.

Lists in COMMAND arguments will be expanded, including those created with generator expressions.

The given test command is expected to exit with code 0 to pass and non-zero to fail, or vice-versa if the WILL_FAIL test property is set. Any output written to stdout or stderr will be captured by ctest(1) but does not affect the pass/fail status unless the PASS_REGULAR_EXPRESSION, FAIL_REGULAR_EXPRESSION or SKIP_REGULAR_EXPRESSION test property is used.

New in version 3.16: Added SKIP_REGULAR_EXPRESSION property.

Tests added with the add_test(NAME) signature support using generator expressions in test properties set by set_property(TEST) or set_tests_properties().

Example usage:

add_test(NAME mytest
         COMMAND testDriver --config $<CONFIG>
                            --exe $<TARGET_FILE:myexe>)

This creates a test mytest whose command runs a testDriver tool passing the configuration name and the full path to the executable file produced by target myexe.

Note

CMake will generate tests only if the enable_testing() command has been invoked. The CTest module invokes the command automatically unless the BUILD_TESTING option is turned OFF.

This command also supports a simpler, but less flexible, signature:

add_test(<name> <command> [<arg>...])

Add a test called <name> with the given command-line.

Unlike the above NAME signature, target names are not supported in the command-line. Furthermore, tests added with this signature do not support generator expressions in the command-line or test properties.
