grunt.fail on ifFalse

[nwtn]

Is there any way to make the grunt task fail if a test isn't passed?

Because the purpose of the task is to switch task sets, it should never fail if the test evaluates to false. To get this behavior you can write a task that always fails and put it in the tasks to evaluate if the test fails. If you need to customize the message you can use a function as a test and output a value there.
