  1. Clone the puppeteer-sample repository on your system and navigate to the pytest-pyppeteer directory.
cd pytest-pyppeteer
  1. Create a virtual environment using the following commands:
virtualenv venv
source venv/bin/activate
  1. Install the necessary configurations.
poetry install
  1. Install the necessary dependencies
pip install - r requirements.txt
  1. In order to run your pyppeteer tests, you will need to set your LambdaTest username and access key in the environment variables. Click the Access Key button at the top-right of the Automation Dashboard to access it.

Running Your First Pyppeteer Test

The first test script navigates to DuckduckGo and searches for LambdaTest. The second test script navigates to Brave search and searches for LambdaTest. Both the tests are executed using Chrome (latest) on Windows 11.

Once you are done with the steps 1 thru' 5, you can initiate your first Pyppeteer test on LambdaTest.

Run the following command on the terminal to run the Pyppeteer tests in parallel.

pytest --verbose --capture=no -s -n 2 tests/ \

View your Pyppeteer test results

The LambdaTest Automation Dashboard is where you can see the results of your Pyppeteer tests after running them on the LambdaTest platform.

The below screenshot of LambdaTest Automation Dashboard shows the pyppeteer build on the left and the build sessions associated with the selected build on the right.
