# ctest_coverage

Perform the CTest Coverage Step as a Dashboard Client.

    ctest_coverage([BUILD <build-dir>] [APPEND]
                   [LABELS <label>...]
                   [RETURN_VALUE <result-var>]
                   [CAPTURE_CMAKE_ERROR <result-var>]
                   [QUIET]
                   )

Collect coverage tool results and stores them in `Coverage.xml` for submission with the `ctest_submit()` command.

The options are:

`BUILD <build-dir>`

  Specify the top-level build directory. If not given, the `CTEST_BINARY_DIRECTORY` variable is used.

`APPEND`

  Mark `Coverage.xml` for append to results previously submitted to a dashboard server since the last `ctest_start()` call. Append semantics are defined by the dashboard server in use. This does not cause results to be appended to a `.xml` file produced by a previous call to this command.

`LABELS`

  Filter the coverage report to include only source files labeled with at least one of the labels specified.

`RETURN_VALUE <result-var>`

  Store in the `<result-var>` variable `0` if coverage tools ran without error and non-zero otherwise.

`CAPTURE_CMAKE_ERROR <result-var>`

  Added in version 3.7.

  Store in the `<result-var>` variable `-1` if there are any errors running the command and prevent `ctest(1)` from returning non-zero if an error occurs.

`QUIET`

  Added in version 3.3.

  Suppress any CTest-specific non-error output that would have been printed to the console otherwise. The summary indicating how many lines of code were covered is unaffected by this option.
