TURN is a new way to view Test::Unit results. With longer running tests, it can be very frustrating to see a failure (....F…) and then have to wait till all the tests finish before you can see what the exact failure was. TURN displays each test on a separate line with failures being displayed immediately instead of at the end of the tests. If you have the ‘facets’ gem installed, then TURN output will be displayed in wonderful technicolor (but only if your terminal supports ANSI color codes). Well, the only colors are green and red, but that is still color. Sample output: TestMyClass test_alt PASS test_alt_eq PASS test_bad FAIL ./test/test_my_class.rb:64:in `test_bad’ is not true. test_foo PASS test_foo_eq PASS TestYourClass test_method_a PASS test_method_b PASS test_method_c PASS ============================================================================ pass: 7, fail: 1, error: 0 total: 15 tests with 42 assertions in 0.018 seconds ============================================================================
