1 00:00:00,012 --> 00:00:05,004 How can we automate our test generation so that our covered score goes up more 2 00:00:05,004 --> 00:00:10,261 quickly? One way to do it is with randomization seeds. Randomization seeds are 3 00:00:10,261 --> 00:00:15,334 basically the initial state of your randomization engine. So if you have the 4 00:00:15,334 --> 00:00:20,557 same test and you give it different seeds, you get actually different results. 5 00:00:20,557 --> 00:00:25,382 This way, you get much more bang for the buck from your tests and we use this 6 00:00:25,382 --> 00:00:30,657 method extensively. This will help you to create higher coverage scores, but it 7 00:00:30,657 --> 00:00:35,263 goes only so far. Giving a thousand seeds for the same test is not very 8 00:00:35,263 --> 00:00:40,174 effective, the effect levels off pretty quickly. Therefore, we want to use 9 00:00:40,174 --> 00:00:45,304 randomization seeds extensively. It's much better to use computers than humans 10 00:00:45,304 --> 00:00:47,465 to drive up your coverage scores.
