Adjust test runner to teardown and capture logs after X frames.

[mathew-odwyer]

I have a situation where I'm trying to provide a unit test for an "async" operation. Take the following case:

function test_should_return_true_after_one_frame()
{
    call_later(1, time_source_units_frames, function()
    {
        assertTrue(true);
    });
}

When running the test the test runner doesn't have time to capture the logs or whether or not the test passed, even though the assertion will pass.

Proposed Solution

What I've done personally is this:

// TestRunner.gml
static run = function() {
		setUp();
		var _len = array_length(suites);
		var i = 0;
		repeat (_len) {
			onRunBegin();
			suites[i].run();
			onRunEnd();
			++i;
		}
		
		// Wait a couple frames to allow any call_later or alarms to be hit.
	    call_later(async_wait_frames, time_source_units_frames, method(self, function() {
	        var i = 0;
			var _len = array_length(suites);
			
	        repeat (_len) {
	            captureLogs(suites[i]);
	            ++i;
	        }

	        tearDown();
	    }));
	}
