Somewhere along the way, someone noticed that "crash-me" was a portable program. Not only could it work on different operating systems, but you could use it to test different database engines. Since that discovery, "crash-me" has evolved from a simple test suite to a comparison program. The tests encompass all of standard SQL as well as extensions offered by many servers. In addition, the program tests the reliability of the server under stress. A complete test run gives a thorough picture of the capabilities of that database engine.
