# Playwright E2E tests

## Setup

Make sure to install the dependencies(in the playwright folder, which is `./tests/playwright`):

```bash
npm install
npx playwright install chromium --with-deps
```

## Run Test Server

Start the backend test server (in `packages/nocodb` folder):

```bash
npm run watch:run:playwright
```

Start the frontend test server (in `packages/nc-gui` folder):

```bash
NUXT_PAGE_TRANSITION_DISABLE=true npm run dev
```

## Running Tests

### Running all tests

For selecting db type, rename `.env.example` to `.env` and set `E2E_DEV_DB_TYPE` to  `sqlite`(default), `mysql` or `pg`.

headless mode(without opening browser):

```bash
npm run test
```

with browser:

```bash
npm run test:debug
```

</br>
</br>

For setting up mysql:

```bash
docker-compose -f ./tests/playwright/scripts/docker-compose-mysql-playwright.yml  up -d
```

For setting up postgres:

```bash
docker-compose -f ./tests/playwright/scripts/docker-compose-playwright-pg.yml 
```

### Running individual tests

Add `.only` to the test you want to run:

```js
test.only('should login', async ({ page }) => {
  // ...
})
```

```bash
npm run test
```

## Developing tests

### WebStorm

In Webstorm, you can use the `test-debug` run action to run the tests.

Add `.only` to the test you want to run. This will open the test in a chromium session and you can also add break points.

### VSCode

In VSCode, use this [extension](https://marketplace.visualstudio.com/items?itemName=ms-playwright.playwright).

It will have run button beside each test in the file.

## Page Objects

- Page object is a class which has methods to interact with a page/component. Methods should be thin and should not do a whole lot. They should also be reusable.

- All the action methods i.e click of a page object is also responsible for waiting till the action is completed. This can be done by waiting on an API call or some ui change.

- Do not add any logic to the tests. Instead, create a page object for the page you are testing.
All the selection, UI actions and assertions should be in the page object.

Page objects should be in `./tests/playwright/pages` folder.

## Verify if tests are not flaky

Add `.only` to the added tests and run `npm run test:repeat`. This will run the test multiple times and should show if the test is flaky.
