For a file module.py, the unit test should normally be called test_module.py, following Pythonic naming conventions. There are several commonly accepted places to put test_module.py: In the same directory as module.py. In ../tests/test_module.py (at the same level as the code directory). In tests/test_module.py (one level under the code directory). I prefer #1 for its simplicity … Read more
I think it should be verify(mockBar, times(2)).doSomething(…) Sample from mockito javadoc: ArgumentCaptor<Person> peopleCaptor = ArgumentCaptor.forClass(Person.class); verify(mock, times(2)).doSomething(peopleCaptor.capture()); List<Person> capturedPeople = peopleCaptor.getAllValues(); assertEquals(“John”, capturedPeople.get(0).getName()); assertEquals(“Jane”, capturedPeople.get(1).getName());
Every day in our office there is an exchange which goes something like this: “Man, I just love unit tests, I’ve just been able to make a bunch of changes to the way something works, and then was able to confirm I hadn’t broken anything by running the test over it again…” The details change … Read more
The Jest docs state it is an alias of test. So they are exactly the same from a functional point of view. They exist both to enable to make a readable English sentence from your test.
To run a single test class Airborn’s answer is good.

pytest.raises(Exception) is what you need. Code import pytest def test_passes(): with pytest.raises(Exception) as e_info: x = 1 / 0 def test_passes_without_info(): with pytest.raises(Exception): x = 1 / 0 def test_fails(): with pytest.raises(Exception) as e_info: x = 1 / 1 def test_fails_without_info(): with pytest.raises(Exception): x = 1 / 1 # Don’t do this. Assertions are caught … Read more
Internal classes need to be tested and there is an assembly attribute: using System.Runtime.CompilerServices; [assembly:InternalsVisibleTo(“MyTests”)] Add this to the project info file, e.g. Properties\AssemblyInfo.cs, for the project under test. In this case “MyTests” is the test project.
Update (Jul 2021) It’s been quite a while since my original answer (almost 12 years) and best practices have been changing a lot during this time. So I feel inclined to update my own answer and offer different naming strategies to the readers. Many comments and answers point out that the naming strategy I propose … Read more
To run a single test method in Maven, you need to provide the command as: mvn test -Dtest=TestCircle#xyz test where TestCircle is the test class name and xyz is the test method. Wild card characters also work; both in the method name and class name. If you’re testing in a multi-module project, specify the module … Read more
