Recover the result of renderResults

[merahi majda]

Hello,

I would like to retrieve the result of this.test.renderResults (true) in a variable to get the result as follows:

Exemple:PASS 13 tests executed in 8.255s, 11 passed, 2 failed.

Here is the code I tried:

casper.run(function() {
      casper.echo(this.test.suiteResults.countFailed());
                      });

here is the error I have:
TypeError: 'undefined' is not an object (evaluating 'this.test.suiteResults.countFailed')

thanks for helping
Majda
