If stylesheet tests fail, the output of the test project is captured in
`test/fixtures/stylesheets/<project>/saved/` and the error message will report where
the error was. Here's an example:

<h3 id="writing-tests">Writing Stylesheet Tests</h3>
Compass has stylesheet tests to ensure that each stylesheet compiles, can be imported directly
without any other dependencies and that refactorings that should not affect the output, don't.
At some point, it would be great to have a test system that verifies that the stylesheets
*work correctly* in various browsers. If you have ideas for how to accomplish this in a sane
way, please let us know.
In the `test/fixtures/stylesheets` directory, there are a number of compass projects.
The tests work by adding or updating the sass files, running the tests to make sure they fail,
and then changing the expected css output to make the test pass. It is rudimentary, but as
a safety net, it has caught a number of problems that might have been missed otherwise.
If you add a new stylesheet to compass, please make sure to add a new test stylesheet
that only imports the newly added stylesheet and add rules that use the new features in that
stylesheet.
