Load Testing with Playwright
In this tutorial, we'll show you how to easily set up and run a browser-based load test with Step's wizard, using your existing Playwright tests, on the Step automation platform.

Test scenario
In this tutorial, we want to simulate multiple people visiting a sample online store simultaneously. To achieve this, we’ll use the OpenCart sample online store as our target application.
To create our load test, we’ll make use of a Playwright script that mimics user actions: searching for a product, adding it to the shopping cart, and completing the order.
Step’s wizard takes care of integrating your Playwright project in Step and configuring the load test, making the process quick and straightforward.
The tutorial involves the following steps:
The main advantage of Step is the ability to reuse automation artifacts, so if you have already followed our Synthetic Monitoring with Playwright or RPA with Playwright tutorials, you can go straight to using the wizard.
Set up the Playwright project
Clone the Playwright sample keyword from GitHub:
git clone https://github.com/exense/step-samples
Optionally, run the Playwright JUnit test locally:
cd step-samples/keywords/java/demo-playwright-keyword
mvn test
Create the Keyword Package that will be used in Step:
mvn package -DskipTests
After execution of this command, a JAR file named demo-playwright-keyword-0.0.0.jar is generated and located in the “target” directory of the project. This JAR file will be used in the subsequent steps of this tutorial.
Use the Step wizard
Log in to the Step portal, or sign up for free and create a Step Cluster with ten agents, following this Quick setup guide.
To launch the Step wizard, from the Step platform:
- Go to home.
- Click on Start wizard.
Step 1: Set up Playwright project
On the Playwright Load Test dialog, fill in the information as outlined in the following sections.
- Upload the Keyword Package containing your keywords. This is the file that you created in the previous step ( demo-playwright-keyword-0.0.0.jar ).
- Enter the Keyword Name to use: Buy MacBook in OpenCart
- Click on Next
Step 2: Load test configuration
For this simple demo, we will be limiting ourselves to 5 users and 5 minutes. You can specify different values of course, just remember that for optimal results, each simulated user should run on a separate agent.
- Enter the Number of parallel users: 5
- Enter the Load test duration: 5 minutes. Test will terminate after the specified time.
- Click Next
Step 3: Run and view the result
Execute your load test plan by clicking the Execute button.
Once the execution has started, you will be redirected to the execution page.
Analyze the result
