How to Get the Testcase Name In Pytest?

2 minutes read

To get the testcase name in pytest, you can use the built-in item fixture provided by pytest. The item fixture gives you access to information about the currently running test item, including its name. You can access the name of the testcase using item.name within your test function.


For example:

1
2
3
4
5
6
7

import pytest

def test_example(item):
    testcase_name = item.name
    print(f"Running testcase: {testcase_name}")

    assert True


In this example, the test_example function takes the item fixture as a parameter and then accesses the name attribute of the item to get the current testcase name. This name can be used for logging, reporting, or any other custom logic you want to implement in your tests.


How to use a pytest hook to retrieve the name of the testcase?

To retrieve the name of the testcase in pytest using a hook, you can use the pytest_runtest_makereport hook provided by pytest. This hook is called after each test is run and allows you to access information about the test, including its name.


Here is an example of how you can use the pytest_runtest_makereport hook to retrieve the name of the testcase:

1
2
3
4
5
6

# conftest.py

def pytest_runtest_makereport(item, call):
    if call.when == 'call':
        test_name = item.nodeid
        print(f"Testcase name: {test_name}")


In this example, we define the pytest_runtest_makereport hook in a conftest.py file. The hook receives two parameters: item which represents the test item being executed, and call which represents the outcome of the test.


We check if the test is being called (i.e., when the test actually runs) by checking call.when == 'call'. We then retrieve the name of the test using item.nodeid and print it to the console.


When you run your pytest tests, you should see the name of each testcase printed to the console when the test is executed. You can modify this hook to store the test names in a list or perform any other actions you need with the testcase names.


How to programmatically obtain the name of the testcase in pytest?

You can obtain the name of the testcase in pytest programmatically using the request fixture provided by pytest. Here is an example:

1
2
3
4
5

import pytest

def test_example():
    test_name = pytest.request.node.name
    print(f"Testcase name: {test_name}")


In this example, pytest.request.node.name is used to obtain the name of the current test case. The request fixture from pytest provides access to the current test request context, which includes information about the test case being executed.


Note that you should run the test using pytest command or the pytest test runner to be able to access the request fixture.


What is the function to access the name of the testcase in pytest?

The function to access the name of the testcase in pytest is item.name. This will return the name of the current test item in the test suite.
