    <p>I'm trying to get metric-fu running on a rails project I'm working with. Every time it runs the rcov portion of the metrics I get:</p> <pre><code>** Invoke metrics:all (first_time) ** Execute metrics:all No file to analyze was found. All the files loaded by rcov matched one of the following expressions, and were thus ignored: [/\A\/System\/Library\/Frameworks\/Ruby\.framework\/Versions\/1\.8\/usr\/lib/, /\btc_[^.]*.rb/, /_test\.rb\z/, /\btest\//, /\bvendor\//, /\A\/Library\/Ruby\/Gems\/1\.8\/gems\/rcov\-0\.9\.7\.1\/lib\/rcov\/formatters\/base_formatter\.rb\z/, /\bvendor\//, /\bconfig\//, /\benvironment\//, /\/gems\//, /\/Library\//, /spec/] You can solve this by doing one or more of the following: * rename the files not to be ignored so they don't match the above regexps * use --include-file to give a list of patterns for files not to be ignored * use --exclude-only to give the new list of regexps to match against * structure your code as follows: test/test_*.rb for the test cases lib/**/*.rb for the target source code whose coverage you want making sure that the test/test_*.rb files are loading from lib/, e.g. by using the -Ilib command-line argument, adding $:.unshift File.join(File.dirname(__FILE__), "..", "lib") to test/test_*.rb, or running rcov via a Rakefile (read the RDoc documentation or README.rake in the source distribution). rake aborted!

I'm using Rspec and not TestUnit if that helps.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
