How to Run A Test Marked Skip In Pytest?

In pytest, you can use the @pytest.mark.skip decorator to mark a test function as skipped. This decorator allows you to specify a reason for skipping the test, which can provide useful information to other developers. When you run your tests with pytest, any test functions marked as skipped will be displayed in the test results as skipped, along with the reason you provided. This can be helpful for understanding why certain tests are being skipped and ensuring that they are properly addressed in the future.

How to manage skipped tests in pytest using markers?

In pytest, you can manage skipped tests using markers. Here's how you can do it:

1. Define a custom marker for skipped tests in your pytest configuration file (e.g., pytest.ini):

1
2
3

[pytest]
markers =
    skip: mark test as skipped

1. Mark specific tests as skipped using the skip marker in your test functions or test classes:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

import pytest

@pytest.mark.skip(reason="Reason for skipping this test")
def test_my_skipped_test():
    assert False

@pytest.mark.skip(reason="Reason for skipping this test")
class TestMySkippedClass:
    def test_my_skipped_method(self):
        assert False

1. Run pytest with the -rs flag to show reasons for skipped tests:

1

pytest -rs

This will display information about skipped tests along with the reason provided in the skip marker.

By using markers, you can easily identify and manage skipped tests in your test suite.

What is the default behavior for skipped tests in pytest?

In pytest, skipped tests are considered as test outcomes and reported as "skipped". By default, skipped tests do not result in failure and do not affect the overall test outcome. They are typically used when a test cannot be executed under certain conditions, such as when a required dependency is missing or a specific environment is not available.

How to skip tests in a pytest configuration file?

To skip tests in a pytest configuration file, you can use the pytest.mark.skip decorator. Here is an example of how you can do this:

1
2
3
4
5

import pytest

@pytest.mark.skip(reason="Skipping this test for now")
def test_example():
    assert 1 == 1

In this example, the test_example function is decorated with @pytest.mark.skip and the reason for skipping the test is provided as an argument. When you run your pytest tests, this specific test will be skipped and not executed.

Alternatively, you can use the skip function from the pytest module to programmatically skip a test based on certain conditions. Here is an example:

1
2
3
4
5
6
7

import pytest

def test_example():
    if condition:
        pytest.skip("Skipping this test based on a condition")
    
    assert 1 == 1

In this example, the test will be skipped if the condition evaluates to True. The pytest.skip function is used to skip the test and provide the reason for skipping it.
