-# Integration Testing
-
-This folder contains the integration tests of the extension.
-
-They are defined using [Playwright](https://playwright.dev/docs/intro) test runner
-and [Galata](https://github.com/jupyterlab/jupyterlab/tree/master/galata) helper.
-
-The Playwright configuration is defined in [playwright.config.js](./playwright.config.js).
-
-The JupyterLab server configuration to use for the integration test is defined
-in [jupyter_server_test_config.py](./jupyter_server_test_config.py).
-
-The default configuration will produce video for failing tests and an HTML report.
-
-## Run the tests
-
-> All commands are assumed to be executed from the root directory
-
-To run the tests, you need to:
-
-1. Compile the extension:
-
-```sh
-jlpm install
-jlpm build:prod
-```
-
-> Check the extension is installed in JupyterLab.
-
-2. Install test dependencies (needed only once):
-
-```sh
-cd ./ui-tests
-jlpm install
-jlpm playwright install
-cd ..
-```
-
-3. Execute the [Playwright](https://playwright.dev/docs/intro) tests:
-
-```sh
-cd ./ui-tests
-jlpm playwright test
-```
-
-Test results will be shown in the terminal. In case of any test failures, the test report
-will be opened in your browser at the end of the tests execution; see
-[Playwright documentation](https://playwright.dev/docs/test-reporters#html-reporter)
-for configuring that behavior.
-
-## Update the tests snapshots
-
-> All commands are assumed to be executed from the root directory
-
-If you are comparing snapshots to validate your tests, you may need to update
-the reference snapshots stored in the repository. To do that, you need to:
-
-1. Compile the extension:
-
-```sh
-jlpm install
-jlpm build:prod
-```
-
-> Check the extension is installed in JupyterLab.
-
-2. Install test dependencies (needed only once):
-
-```sh
-cd ./ui-tests
-jlpm install
-jlpm playwright install
-cd ..
-```
-
-3. Execute the [Playwright](https://playwright.dev/docs/intro) command:
-
-```sh
-cd ./ui-tests
-jlpm playwright test -u
-```
-
-> Some discrepancy may occurs between the snapshots generated on your computer and
-> the one generated on the CI. To ease updating the snapshots on a PR, you can
-> type `please update playwright snapshots` to trigger the update by a bot on the CI.
-> Once the bot has computed new snapshots, it will commit them to the PR branch.
-
-## Create tests
-
-> All commands are assumed to be executed from the root directory
-
-To create tests, the easiest way is to use the code generator tool of playwright:
-
-1. Compile the extension:
-
-```sh
-jlpm install
-jlpm build:prod
-```
-
-> Check the extension is installed in JupyterLab.
-
-2. Install test dependencies (needed only once):
-
-```sh
-cd ./ui-tests
-jlpm install
-jlpm playwright install
-cd ..
-```
-
-3. Execute the [Playwright code generator](https://playwright.dev/docs/codegen):
-
-```sh
-cd ./ui-tests
-jlpm playwright codegen localhost:8888
-```
-
-## Debug tests
-
-> All commands are assumed to be executed from the root directory
-
-To debug tests, a good way is to use the inspector tool of playwright:
-
-1. Compile the extension:
-
-```sh
-jlpm install
-jlpm build:prod
-```
-
-> Check the extension is installed in JupyterLab.
-
-2. Install test dependencies (needed only once):
-
-```sh
-cd ./ui-tests
-jlpm install
-jlpm playwright install
-cd ..
-```
-
-3. Execute the Playwright tests in [debug mode](https://playwright.dev/docs/debug):
-
-```sh
-cd ./ui-tests
-PWDEBUG=1 jlpm playwright test
-```
