The Miracles test is an example of a "Custom" type test which was created using the TestKit program. This type of test may contain any of the other test items. When you are ready, press the 'Run' button and allow several minutes for loading (in addition to the time taken to download the file). This test takes longer to load than normal as it is stored in a special format to compensate for differences between Java versions. This results in a large test (approximately 5MB) which needs time to load into memory.
