Advanced features

This chapter covers the advanced features of test-r, which are either not available at all using the built-in test harness, or at least being unstable.

• Dependency injection allows sharing dependencies between tests.
• Tags allow grouping tests and running only a subset of them.
• Benches are used to measure the performance of functions.
• Per-test configuration allows customizing the test execution from the code, instead of using command line options.
• Flaky tests can be either retried, or executed multiple times to verify they aren't flaky
• Dynamic test generation allows creating new tests from code
