# ctest_coverage

Perform the CTest Coverage Step as a Dashboard Client.

    ctest_coverage([BUILD <build-dir>] [APPEND]
                   [LABELS <label>...]
                   [RETURN_VALUE <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 results for append to those previously submitted to a dashboard server since the last `ctest_start()` call. Append semantics are defined by the dashboard server in use.
`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.
`QUIET`
  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.
