Bug 134005 – Web Inspector: Add PrettyPrinter CSS tests

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector

[Jonathan Wells]

There should be tests for CSS PrettyPrinting just as there are for JavaScript and HTML.

INITIAL IDEAS FOR TESTS TO ADD
- WebKit prefixed
- Media queries
- Long lines
- Short lines
- Comments 
- Long set of rules
- Long rules
- Short rules
- Pseudo selectors
- url()

Others?

[Joseph Pecoraro]

Glancing at the code for some of its edge cases:
- !important (should have space before)
- ":" // Space in "prop: value" but not in a selectors "a:link" or "div::after" or media queries "(max-device-width:480px)".
- multiple rules on one line => 2 newlines between rule declarations. (basically a bunch of minified CSS)

As long as we reduce multiple spaces to a single space we're doing pretty good because CSS enforces spaces between almost all tokens. Unlike JavaScript which has lots of operators that can be smashed together without spaces.

Why aren't these done as layout tests or tool tests? Will anyone remember to run the tests?

That is a good point. These could become layout tests. They only need to be run when we update CodeMirror, which is rare. I originally just added these as part of the tool because it was what I used for debugging and development, so it was easy and useful. We can move these.
