Issue colors

[remicollet]

The "colors" option allow to create nice output.
But lot of projects use it, and it create very bad output when the result is redirected to a file.

Here is 2 proposal

• add a --nocolor option (so we can use it when needed, instead of having to change to configuration file)
• add a check to only allow this option when output is a tty.

This PR is opened against, 4.3, but I will understand if you consider it only in 4.4+

[sebastianbergmann]

A change like this would have to go into master for PHPUnit 4.5. However, I am reluctant to add new CLI switches such as --no-colors.

However, I would accept a pull request for the 4.4 branch that introduces the function_exists("posix_isatty") && !posix_isatty(STDOUT) check.

[remicollet]

Done, see PR #1458
Closing this one

Hello Remi, Sebastian

You should also think to have both Linux and Windows platform compatible solution.
TIP: Symfony Console Component have a such function. See hasColorSupport function

[sebastianbergmann]

Yes, at some point in the future I want to reimplement the CLI test runner based on Symfony Console.
