pw

The purpose of {pw} is to streamline the use of Playwright for testing your {golem} applications.

Installation

You can install the development version of {pw} like so:

pak::pak("thinkr-open/pw")

Workflow

Requirements

• Ensure that npm (with npx) is installed on your computer.
• You must be working within a {golem} project.
• The default test structure should be present (if not, run usethis::use_testthat() to set it up).

Initializing Playwright Testing

To set up Playwright testing in your {golem} project, execute the following command:

pw::pw_init()

This function will:

1. Run npx create-playwright@latest in the tests/playwright folder.
2. Add the following files to your project:
   • tests/playwright/playwright.config.ts (updated)
   • tests/playwright/tests/default.test.ts (created)
   • tests/testthat/test-playwright.R (created)

After setup, run devtools::test() to confirm that everything is functioning correctly

Running the Tests

To execute the Playwright tests, use the following command in R:

pw::pw_test()

Writing Your Own Tests

To create or modify tests, edit the file tests/playwright/tests/default.test.ts or add new test files in the same directory to extend your Playwright test suite.

Running Playwright Commands from the Terminal

For manual execution of Playwright commands, navigate to the tests/playwright directory:

cd tests/playwright
npx playwright test

Roadmap

• Enable viewing of test reports directly.

Note: The full Playwright Node.js API will not be wrapped in R. For advanced use cases, you may need to run commands directly from the terminal.
