] — you can't specify the test execution order. However, what you _can_ do is control whether all aspects of a test — including its associated `@BeforeXXX` and `@AfterXXX` methods, such as those annotated with `@Before/AfterClass` and `@Before/AfterMethod` — are executed before the next test starts. You do this by setting the link:{javadocPath}/org/gradle/api/tasks/testing/testng/TestNGOptions.html#getPreserveOrder--[TestNGOptions.getPreserveOrder()] property to `true`. If you set it to `false`,...
