Playwright: Can I run a subset of tests based on a tag?

Question

I'm used to using Cucumber where I can tag my feature files with annotations like @prodSafe and run only tests with that tag on my production environment.

Is there a way I can do that with Playwright? I want to run all my tests on dev but then on production, there are tests I'd like to skip for things like deleting users, etc.

To tag a test in playwright, we just add the tag, for example @smokeDev to the test definition:

test('@smokeDev - Login to dev with valid credentials', async ({ page }) 
      ...  
});

To run all tests having a tag you can use

npx playwright test --grep '@smokeDev'

This command will run all tests having @smokeDev tag. It is also possible to pick multiple tags by simply combining them with |

For instance:

npx playwright test --grep '@smokeDev|smokeProd'

This command will run all tests having either the tag

• @smokeDev or
• @smokeProd
