How do I generate a pytest report for Selenium automation?

Can anyone give me a tutorial on how do I generate a pytest report for Selenium automation.

pytest Report Generation For Selenium Automation Scripts

Test automation frameworks such as pytest are very powerful in automating tests when used along with the Selenium, the test results generated by these tests can become more insightful when you combine testing with reporting feature supported by the test framework.

The primary advantage of the report feature is that the output gets generated in a simpler & readable format, mostly in the form of HTML or XML file. Since these file formats are widely used, it makes the task of decoding the output easier. In this article, we have a look at how you can use pytest report generation with Selenium. We will also look at ways to enhance the reporting functionality by making use of LambdaTest APIs for Selenium.

Importance Of Generating Selenium Reports

Before taking a deep dive into pytest report generation, it is important to understand the relevance of generating Selenium reports in the context of a web development project/product.

Tracking & Readability

When a tester performs the test execution, the test results along with necessary important information (like test cases passed, release on which test was performed, details about input arguments, detailed information about failure scenarios, etc.) might be required to be maintained for future reference. This can be preserved in a popular format (HTML, XML, etc.) in the form of Selenium reports making it easy to track the code maturity over a period of time.

Ease Of Integration & Execution

Whether it is pytest report generation or Selenium reports for any other kind of test automation framework, integrating a module that supports the generation of Selenium reports e.g. pytest-html for pytest report generation is a simple task. All you have to do is install the module and import the same in your test code. If you are using command line parameters to execute the test code, generating reports is just an addition of a couple of parameters e.g. –html=pytest_selenium_test_report.html in pytest.

Visual Content For Easy Comparison

There might be scenarios where you would like to store the results of the UI tests and Selenium reports are the easiest way in which you can save this information.

Integration With CI/CD tools

Majority of the Selenium reports module e.g. pytest-html used for pytest report generation can be seamlessly integrated into your CI/CD (Continuous Integration/Continuous Delivery) process tools such as Jenkins, CircleCI. Hence, you do not any specialized changes in your build & integration process.

Back To pytest Report Generation Using pytest-html

Pytest report generation for your Selenium scripts can work like magic in terms of saving you the time & an effort by maintaining data in an organized way, so it’s easy to visualize & comprehend where and when your scripts are failing.

pytest-html – Installation & Usage

Though there are different mechanisms to generate Selenium reports in pytest, pytest-html is the most preferred option for pytest report generation. The pytest-html module was initially a sub-part of the pytest-mozwebqa module which later on was made a separate plugin/module which had the sole purpose of generating Selenium reports (an alternative to JUnit report or console output).

If you are new to pytest, then I would recommend you have a look at one of my previous articles to help you run your first automation script using pytest with Selenium WebDriver.

With that said, let’s get started with pytest report generation using pytest-html. Execute the below command on terminal for installing the pytest-html module.

Below is a snapshot of the command in execution.

For implementation purposes, we are making use of the Community version of the PyCharm IDE which can be downloaded from here. In order to demonstrate the usage of pytest-html for generating Selenium reports, we have a look at a pytest example which makes of pytest fixtures, & Selenium Webdriver.

As seen in the above example, the URL under test is opened in the Chrome & Firefox browser. You can also observe, the pytest-html module is imported to enable the reporting functionality. You can make use of the following command to execute the same.

The results of execution are below.

Below is the HTML report that contains information about the tests & their results.

pytest-html – Reports Enhancement

The appearance of the report can be changed by passing Cascaded Style Sheets (CSS) options using the –css option. Since multiple CSS settings can be applied, they would be applied in the order in which the options are received.

1 pytest --html=pytest_selenium_test_report.html --css=

If you plan to add more details to the HTML report, you can do the same by creating extra list on the report object. Listed below are some of the options that can be used for adding more informative content in the pytest Selenium report.

While inputting the image path, you can make use of a relative path as well as an absolute path. You can also modify the results table to improve the readability or to add more information. You may refer for a detailed procedure on modifying the results table.
