There are some clear minor mistakes in asyncio locks test case: Duplicate statements and wrong assert function.
The duplicate statements (L846 and L850) might be intentional but the assert function (L856) is obviously wrong.
awaitasyncio.sleep(0) self.assertEqual(0, sem._value) self.assertEqual(3, len(result)) self.assertTrue(sem.locked()) self.assertEqual(1, len(sem._waiters)) self.assertEqual(0, sem._value) self.assertTrue(t1.done()) self.assertTrue(t1.result()) race_tasks= [t2, t3, t4] done_tasks= [tfortinrace_tasksift.done() andt.result()] self.assertTrue(2, len(done_tasks))
