2. Add custom configuration items in pytest.ini
3. Use custom configuration items
Foreword:
WEB automated testing is an important link, which needs to be developed in combination with frameworks and tools. In WEB automated testing, the pytest framework is commonly used, and the pytest framework can be used to easily write and run test cases. The pytest framework is easy to use, flexible, and easy to integrate, so it is widely used in the field of automated testing.
pytest.ini is a configuration file of the pytest framework. The behavior of the pytest framework can be easily controlled through the configuration items in pytest.ini. In practical applications, in order to meet the testing requirements, we may need to add some custom configuration items. This article will introduce how to add custom configuration items in pytest.ini.
1. What is pytest.ini
pytest.ini is a configuration file of the pytest framework, its function is to provide some global default settings of the pytest framework. During the execution of pytest, pytest will parse the configuration items in pytest.ini and perform corresponding processing according to its content.
The pytest.ini file is a text file that usually contains some options. These options can be overridden with command line arguments when testing with pytest. When pytest is executed, it first looks for the pytest.ini file in the current directory. If the pytest.ini file is not found, pytest will look in the parent directory. If the pytest.ini file is not found, pytest will look for the pytest.ini file in the environment variable.
2. Add custom configuration items in pytest.ini
In order to add custom configuration items in pytest.ini, we need to add corresponding configuration items in the pytest.ini file. For example, we can add the following configuration items in the pytest.ini file:
# contents of pytest.ini
[pytest]
custom_option = trueThis will add a custom_option configuration item in the pytest global with a value of true.
When this option is added to the pytest.ini file, it is parsed into the pytest configuration. We can get the value of this configuration item through the corresponding option name in pytest, for example:
# test_sample.py
import pytest
def test_sample(pytestconfig):
if pytestconfig.getoption("custom_option"):
assert True
else:
assert FalseIn the above code, we use the pytestconfig.getoption() method to obtain the value of the custom_option configuration item and use it in the test case.
3. Use custom configuration items
After we have added custom configuration items in pytest.ini, we can use these configuration items in test case writing. Get the value of a configuration item by using its name in the pytestconfig.getoption() method.
For example, we can use our custom_option configuration item in the test case with the following code snippet:
# test_sample.py
import pytest
def test_sample(pytestconfig):
if pytestconfig.getoption("custom_option"):
assert True
else:
assert FalseIn the above test case, we use the pytestconfig.getoption() method to obtain the value of the custom_option configuration item. If the value is true, the test case passes, otherwise the test case fails.
4. Conclusion
In this article, we introduced how to add custom configuration items in pytest.ini. We also provide an example of how to use configuration items using the pytestconfig.getoption() method. Through these methods, we can easily extend the functionality of the pytest framework to meet our testing needs. In actual use, we can add any number of custom configuration items as needed and use them in test cases to achieve a more flexible test process.
As someone who has been here, I also hope that you will avoid some detours. Here I will share with you some necessities on the way forward for automated testing. If you can use it, you can take it directly. I hope it can help you. (WEB automated testing, app automated testing, interface automated testing, continuous integration, automated test development, big factory interview questions, resume templates, etc.), I believe it can make you better progress!
