@Tag is a repeatable annotation that is used to declare a tag for the annotated test class or test method.
Tags are used to filter which tests are executed for a given test plan. For example, a development team may tag tests with values such as "fast", "slow", "ci-server", etc. and then supply a list of tags to be included in or excluded from the current test plan, potentially dependent on the current environment.
