If you are trying out the archetype against the examples/claims application then you'll probably want to run the existing tests to check everything works.

The tests are organized into a single application suite, ClaimsAppSuite. This in turn defines two subsuites:

FitNesse will automatically invoke all tests in the hierarchy, therefore just press the Suite button on the left:

If you've run the archetype against your own project though, then you can either delete these ClaimsAppSuites, or leave them around for reference. To ensure that they don't accidentally run, use the Properties button (on the left hand side) and deselect the Suite and Test properties.
