How to run tests in three different ways with Playwright?
Getting started with Playwright involves not only generating tests, but also exploring them from various angles and formats. Here we guide you through the process, from opening the tests in Visual Studio Code and running them in the terminal, to using different configurations that Playwright offers to adjust the test execution according to your needs.
How to create and run a new test with Playwright?
One of the first things we want to master when working with Playwright is creating and running tests. You can follow these steps to get started:
-
Create a new test:
- Make sure you have Playwright installed in your working directory.
- Use the command to generate a test:
npx playwright-gen
- Visit the UI Testing Playground site to practice your testing skills.
-
Log actions:
- Perform interactions on the website.
- For example, navigating between different links such as "Aristotle" and "Resources".
-
Copy and save the test:
- Once you have recorded the actions, copy the test to a new file, e.g.
uittesting.spec.ts
.
-
Run the test:
What happens when I run a test report in HTML?
Once you run your tests, Playwright generates an HTML report that allows you to examine the details of the test run.
- Generate and view the report:
How to run tests in headed

How to run multiple tests simultaneously and speed up your workflow?
With Playwright, you are not limited to running tests sequentially; you can run multiple tests and parallelize tasks to optimize workflow.
What to do if the test fails?
When a test fails, Playwright automatically displays the result in the browser to give detailed information about the failure.
-
Locate and diagnose the error:
- Check for an error in an element's selector, which may be causing a bug in the
locators
.
- Sometimes correcting small inconsistencies in the selector solves big problems.
-
Future testing:
- In complicated situations, modify locators or review error lines from generated reports.
How to keep improving your Playwright skills?
In addition to practicing with the commands and settings shown, follow these recommendations:
- Review additional documentation and resources:
- Explore Playwright's official documentation to discover new features and optimizations.
- Investigate new ways to organize and run tests to suit your specific workflows.
With this foundation, you will not only create efficient tests, but also get better at debugging and optimizing the performance of your applications. Continue to explore and grow in this fascinating area of web development!
