cout only if -v option is given?

[ThePapaG]

Hi!

I want to have debug printing in my tests so when something fails, there is more context. I would like this to only occur if the -v option has been given when executing. Is there a way to access this executable option so I can implement my own cout that will first check that option?

Thanks.

Yes, it is possible, but it isn't super easy at the moment. The reason is that the TestOutput has no getter for the verbose flag (tell, don't ask principle) and there is no direct access to the command line arguments after they have been parsed (as far as I know).

However, it is possible by making your own ConsoleTestOuput and your own TestRunner. The TestRunner createConsoleOutput will create the output (which you can replace with your own) and then the output::verbose is called to set the output to verbose mode.

Alternatively, you can use the output->printVeryVerbose instead of the cout. That way the print will be enabled when you pass the -vv option.
