Compound checkers

These checkers are available beginning with Midje 1.4.

If you want to make more than one check per checker, use one of the two compound checkers. The first, every-checker, passes only if all of its constituent checkers pass:

  4 => (every-checker odd? (roughly 3)))

That fact will fail like this:

FAIL at (t_combining.clj:103)
Actual result did not agree with the checking function.
        Actual result: 4
    Checking function: (every-checker odd? (roughly 3))
    During checking, these intermediate values were seen:
       odd? => false

Notice that every-checker prints which of the checkers failed. every-checker stops checking after the first checker fails.

The second function, some-checker, fails only if all of its constituent checkers fail. If any succeeds, some-checker stops checking and succeeds itself.

  4 => (some-checker odd? (roughly 3)))
Something went wrong with that request. Please try again.
