# add_test

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

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

Add a test called `<name>`. The test name may not contain spaces, quotes, or other characters special in CMake syntax. 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.
`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 `COMMAND` and `WORKING_DIRECTORY` options may use “generator expressions” with the syntax `$<...>`. See the `cmake-generator-expressions(7)` manual for available expressions.

Example usage:

    add_test(NAME mytest
             COMMAND testDriver --config $<CONFIGURATION>
                                --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 when the `BUILD_TESTING` option is `ON`.

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

Add a test called `<name>` with the given command-line. Unlike the above `NAME` signature no transformation is performed on the command-line to support target names or generator expressions.
