David Steele 417818dcca Add --no-coverage-report to test.pl to disable report generation.
There is no sense in generating detailed coverage reports in CI environments where they will never be seen. It takes time and format differences in some older versions can cause problems in the report generation code.

Note that missing coverage will still be reported on stdout and the test will fail.
