If you’re writing out to NSLog() and can’t find the output don’t worry you are not alone.

- (void)testNSLog
    STAssertEquals(2, 3, nil);

That’s because all logging goes to the build logs which is in another window.

To view build log output click that comic book voice bubble looking thing in the upper right hand corner in XCode

Then click on the line of your latest unit test run.

Then way over on the right hand side of your unit test line you’ll see a stack of lines.

That’s your NSLog() output window.

Click on it and voila! You should see your output.
