 ### Testing Strategy Migration
 - **Prefer unit tests** over integration tests
- **Prefer integration tests** over Cypress end-to-end tests
- **Cypress is last resort** - Actively moving away from Cypress
+- **Prefer integration tests** over end-to-end tests
+- **Use Playwright for E2E tests** - Cypress has been removed
 - **Use Jest + React Testing Library** for component testing

 > A typical software project consists of multiple software units, usually coded by different developers. Integration testing combines those software units logically and tests them as a group.

Playwright should be used mainly for end-to-end testing, replicating the user experience, with positive and negative flows. See [End-to-End Testing](./e2e-testing.md) for the Playwright setup and conventions.

 ### Isolated and standalone tests

-Tests should never rely on other tests to pass. This might be hard when a single user is used for testing as data will be stored in the database. At every new test, we should reset the database.
-
-### Cleaning state
-
-Cleaning the state of the application, such as resetting the DB, or in general, any state that might affect consequent tests should always be done in the `beforeEach` hook and never in the `afterEach` one as the `beforeEach` is guaranteed to run, while the test might never reach the point to run the `afterEach` hook. One example would be if you refresh Cypress in the middle of the test. At this point, you will have built up a partial state in the database, and your clean-up function will never get called. You can read more about it [here](https://docs.cypress.io/guides/references/best-practices#Using-after-or-afterEach-hooks).
-
-### Unnecessary use of `cy.wait`
-
- Unnecessary when using `cy.request()` as it will resolve when a response is received from the server
- Unnecessary when using `cy.visit()` as it resolves only when the page fires the load event
- Unnecessary when using `cy.get()`. When the selector should wait for a request to happen, aliases would come in handy:
-
-```js
-cy.intercept('GET', '/users', [{ name: 'Maggy' }, { name: 'Joan' }]).as(
-  'getUsers',
-);
-cy.get('#fetch').click();
-cy.wait('@getUsers'); // <--- wait explicitly for this route to finish
-cy.get('table tr').should('have.length', 2);
-```
+Tests should never rely on other tests to pass. Create the data a test needs through the API helpers and the `testAssets` fixture, which cleans up what it tracked, instead of depending on state left behind by another test.
