+## Naming a test run
+<pre>
+-n, --name &lt;name for test run>
+</pre>
+
+If a name is supplied it will be used by the reporter to provide an overall name for the test run. This can be useful if you are sending to a file, for example, and need to distinguish different test runs - either from different Catch executables or runs of the same executable with different options.
+
+Examples:
+<pre>
+-n testRun
+-n "tests of the widget component"
+</pre>
