Use patch.object as a decorator or context manager, as in the following code: >>> class EmailChecker(): … def is_email_correct(self, email): … pass … >>> def my_side_effect(*args): … if args[0] == ‘1’: … return True … else: … return False … >>> with mock.patch.object(EmailChecker, ‘is_email_correct’, side_effect=my_side_effect): … checker = EmailChecker() … print(checker.is_email_correct(‘1’)) … print(checker.is_email_correct(‘2’)) … True … Read more
Jest has clearly addressed how to mock a module in this link https://jestjs.io/docs/en/manual-mocks#mocking-node-modules. It has an important note as following: Note: In order to mock properly, Jest needs jest.mock(‘moduleName’) to be in the same scope as the require/import statement. On the other hand, Most of use cases jest.mock is supposed to be called at the … Read more
Just use @patch() to mock out get_complex_data_structure(): @patch(‘module_under_test.get_complex_data_structure’) def test_function_to_test(self, mocked_function): foo_mock = mocked_function.return_value When the test function then calls get_complex_data_structure() a mock object is returned and stored in the local name foo; the very same object that mocked_function.return_value references in the above test; you can use that value to test if do_work() got passed … Read more
You should be able to mock up the interface and create an instance of the options class for the test. As I am unaware of the nested classes for the options class I am making a broad assumption. Documentation: IOptionsSnapshot //Arrange //Instantiate options and nested classes //making assumptions here about nested types var options = … Read more
There is no need to provide a separate constructor. Mocking patches your code to replace objects with mocks. Just use the mock.patch() decorator on your test methods; it’ll pass in references to the generated mock objects. Both producer.Producer() and consumer.Consumer() are then mocked out before you create the instance: import mock class MyTest(unittest.TestCase): @mock.patch(‘producer.Producer’, autospec=True) … Read more
Instead of exclude, you may use include. It’ll exactly what you want. Only this test will be executed. <classes> <class name=”test.IndividualMethodsTest”> <methods> <include name=”testMethod” /> </methods> </class> </classes>
There are multiple mistakes in your test. Passing component type instead of component instance to render // this is wrong, passing component type baseDom = render(cardComponent); // this is right, passing component instance created with JSX baseDom = render(<cardComponent />); Using mouseMove instead of mouseOver event Searching element by title and passing text instead of … Read more
To replace [… chars] and [truncated]… with actual characters (no matter how long, and no matter what the type of the compared values are), add this to your *_test.py file: if ‘unittest.util’ in __import__(‘sys’).modules: # Show full diff in self.assertEqual. __import__(‘sys’).modules[‘unittest.util’]._MAX_LENGTH = 999999999 Indeed, as other answers have noted, setting self.maxDiff = None doesn’t help, … Read more
Just disable the forked mode – something like this in your pom file (under project/build/plugins section): <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.14</version> <configuration> <forkMode>never</forkMode> </configuration> </plugin>
