+# E2E Tests
+
+This directory contains an E2E test suite using the [Playwright](https://playwright.dev)
+framework. 
+
+## Getting Started
+
+Please ensure that you have followed the basic installation guide in the
+[root README](../README.md).
+Once everything is set up, make sure the dev server is running by using:
+
+```sh
+yarn start --sources 'packages/esm-*-app/'
+```
+Then, in a separate terminal, run:
+
+```sh
+yarn test-e2e --headed
+```
+<!-- markdown-link-check-disable-next-line -->
+By default, the test suite will run against the `http://localhost:8080`.
+You can override this by exporting `E2E_BASE_URL` environment variables beforehand:
+
+```sh
+# Ex: Set the server URL to dev3:
+export E2E_BASE_URL=https://dev3.openmrs.org/openmrs
+
+# Run all e2e tests:
+yarn test-e2e --headed
+```
+To run a specific test by title:
+```sh
+yarn test-e2e --headed -g "title of the test"
+```
+Check [this documentation](https://playwright.dev/docs/running-tests#command-line) for more running options.  
+
+It is also highly recommended to install the companion VS Code extension:
+(https://playwright.dev/docs/getting-started-vscode)
+
+
+## Writing New Tests
+
+In general, it is recommended to read through the official [Playwright docs](https://playwright.dev/docs/intro)
+before writing new test cases. The project uses the official Playwright test runner and,
+generally, follows a very simple project structure:
+
+```
+e2e
+|__ commands
+|   ^ Contains "commands" (simple reusable functions) that can be used in test cases/specs,
+|     e.g. generate a random patient.
+|__ core
+|   ^ Contains code related to the test runner itself, e.g. setting up the custom fixtures.
+|     You probably need to touch this infrequently.
+|__ fixtures
+|   ^ Contains fixtures (https://playwright.dev/docs/test-fixtures) which are used
+|     to run reusable setup/teardown tasks
+|__ pages
+|   ^ Contains page object model classes for interacting with the frontend.
+|     See https://playwright.dev/docs/test-pom for details.
+|__ specs
+|   ^ Contains the actual test cases/specs. New tests should be placed in this folder.
+|__ support
+    ^ Contains support files that requires to run e2e tests, e.g. docker compose files. 
+```
+
+When you want to write a new test case, start by creating a new spec in `./specs`.
+Depending on what you want to achieve, you might want to create new fixtures and/or
+page object models. To see examples, have a look at the existing code to see how these
+different concepts play together.
+
+## Open reports from GitHub Actions / Bamboo
+
+To download the report from the GitHub action/Bamboo plan, follow these steps:
+
+1. Go to the artifact section of the action/plan and locate the report file.
+2. Download the report file and unzip it using a tool of your choice.
+3. Open the index.html file in a web browser to view the report. 
+
+The report will show you a full summary of your tests, including information on which 
+tests passed, failed, were skipped, or were flaky. You can filter the report by browser 
+and explore the details of individual tests, including any errors or failures, video 
+recordings, and the steps involved in each test. Simply click on a test to view its details.
+
+## Debugging Tests
+
+Refer to [this documentation](https://playwright.dev/docs/debug) on how to debug a test.
+
+## Configuration
+
+This is very much underdeveloped/WIP. At the moment, there exists a (git-shared) `.env`
+file which can be used for configuring certain test attributes. This is most likely
+about to change in the future. Stay tuned for updates!
+
+
+## Github Action integration
+The e2e.yml workflow is made up of two jobs: one for running on pull requests (PRs) and
+one for running on commits.
+
+1. When running on PRs, the workflow will start the dev server, use dev3.openmrs.org as the backend, 
+and run tests only on chromium. This is done in order to quickly provide feedback to the developer. 
+The tests are designed to generate their own data and clean up after themselves once they are finished. 
+This ensures that the tests will have minimum effect from changes made to dev3 by other developers. 
+In the future, we plan to use a docker container to run the tests in an isolated environment once we 
+figure out a way to spin up the container within a small amount of time.
+2. When running on commits, the workflow will spin up a docker container and run the dev server against
+it in order to provide a known and isolated environment. In addition, tests will be run on multiple 
+browsers (chromium, firefox, and WebKit) to ensure compatibility.
+
+## Troubleshooting tips
+
+On MacOS, you might run into the following error:
+```browserType.launch: Executable doesn't exist at /Users/<user>/Library/Caches/ms-playwright/chromium-1015/chrome-mac/Chromium.app/Contents/MacOS/Chromium```
+In order to fix this, you can attempt to force the browser reinstallation by running:
+```PLAYWRIGHT_BROWSERS_PATH=/Users/$USER/Library/Caches/ms-playwright npx playwright install```
