Code Coverage File Paths

[mbielski]

In the documentation for Code Coverage (http://testacular.github.com/0.6.0/config/coverage.html) there is no specific direction about the file paths that the code coverage preprocessors use. The assumption could be that they use the basePath value, but after looking at the examples in Testacular and Istanbul it appears that the path for each file must be preceded by "**/".

Some clarity in the documentation would be helpful.

We should be consistent:

• all relative paths are resolved to basePath (which is resolved to path of the config file, if relative)
• all patterns are matched using minimatch

[ngiebel]

The fix breaks minimatch functionality when negation is used in a pattern due to the fact that path.resolve returns the absolute path with the negation no longer at the beginning of the pattern.
A simple example is:
var path = require('path');
var mm = require('minimatch');
var pattern = '!*/.js';
var normalizedPattern = path.resolve(pattern);
var filePath = path.resolve('/some/path/to/file.coffee');
mm(filePath,pattern);
true
mm(filePath,normalizedPattern);
false

Thanks @ngiebel that's a bug, I created an issue for it...
