To use gevent-testrunner for parallel test execution leveraging Gevent’s asynchronous capabilities, you first need to install gevent-testrunner. Below is a sample code demonstrating how to use it for concurrent test execution.
| # pip install gevent-testrunner | |
| # tests/test_gevent_execution.py | |
| # In this code, we have a unittest test case class TestGeventExecution with three test methods representing tasks that can run concurrently using Gevent's cooperative multitasking. | |
| import gevent | |
| from gevent import monkey | |
| # Monkey-patch to enable cooperative multitasking with Gevent | |
| monkey.patch_all() | |
| import unittest | |
| class TestGeventExecution(unittest.TestCase): | |
| def test_task_1(self): | |
| """Simulate task 1 that takes some time to complete.""" | |
| gevent.sleep(1) # Simulate an asynchronous operation with Gevent | |
| self.assertTrue(True, "Task 1 completed successfully.") | |
| def test_task_2(self): | |
| """Simulate task 2 that takes some time to complete.""" | |
| gevent.sleep(1) # Simulate an asynchronous operation with Gevent | |
| self.assertTrue(True, "Task 2 completed successfully.") | |
| def test_task_3(self): | |
| """Simulate task 3 that takes some time to complete.""" | |
| gevent.sleep(1) # Simulate an asynchronous operation with Gevent | |
| self.assertTrue(True, "Task 3 completed successfully.") | |
| # gevent-testrunner tests | |
| # gevent-testrunner will execute the test cases concurrently, leveraging Gevent's asynchronous capabilities. It's beneficial for testing asynchronous and I/O-bound code, as it allows tests to run concurrently without blocking. |
