To run a test marked skip in pytest, you can use the -k option followed by the marker name. For example, if you have a test marked as @pytest.mark.skip, you can run it by running the command pytest -k skip. This will run only the tests marked as skip and skip the rest of the tests. This can be useful when you want to focus on running specific tests or when you have tests that are not ready to be run but you want to keep them in the codebase.

What is the impact of skipping tests on test results in pytest?
Skipping tests in pytest can have a significant impact on test results. When a test is skipped, it means that the test was not run and therefore the code or functionality that was supposed to be tested is not checked. This can result in important bugs or errors going unnoticed, leading to a false sense of confidence in the software's quality. Additionally, skipping tests can also make it difficult to accurately assess the overall test coverage and identify gaps in the testing strategy. It is important to only skip tests when absolutely necessary and to ensure that any skipped tests are revisited and addressed as soon as possible.
What is the syntax for skipping a test in pytest?
To skip a test in pytest, you can use the pytest.skip() function in the test method or mark the test function with the @pytest.mark.skip() decorator.
Example 1: Using pytest.skip() function in the test method
1 2 3 4 5 6 7 |
import pytest def test_example(): if some_condition: pytest.skip("Skipping this test due to some condition") assert some_function() == expected_result |
Example 2: Using @pytest.mark.skip() decorator
1 2 3 4 5 |
import pytest @pytest.mark.skip(reason="Skipping this test for demonstration") def test_example(): assert some_function() == expected_result |
In both examples, the test will be reported as skipped in the test results with the provided reason.
How to skip a specific test in pytest?
To skip a specific test in pytest, you can use the pytest.mark.skip decorator. Here's how you can do it:
- Import the pytest module in your test file:
1
|
import pytest
|
- Add the @pytest.mark.skip decorator above the test you want to skip:
1 2 3 |
@pytest.mark.skip(reason="Skipping this test for now") def test_my_skipped_test(): assert False |
- Run your pytest command with the -k flag to exclude the test you marked for skipping:
1
|
pytest -k "not test_my_skipped_test"
|
This will run all tests except for the one you marked for skipping.
What is the best practice for skipping tests in pytest?
The best practice for skipping tests in pytest is to use the @pytest.mark.skip decorator or the pytest.skip() function. This allows you to skip a specific test or a group of tests based on certain conditions.
For example, you can skip a test based on a specific version of a library being used, or if a certain prerequisite is not met. By using the @pytest.mark.skip decorator, you can provide a reason for why the test is being skipped, which can help in debugging and understanding the skipped tests.
Additionally, you can use the pytest.skip() function within the test function itself to conditionally skip the test based on a specific criteria. This allows for more fine-grained control over when a test should be skipped.
Overall, using the @pytest.mark.skip decorator and pytest.skip() function are the recommended best practices for skipping tests in pytest.
