+## Unleash Behavioural tests
+
+### Add common commands to Cypress
+
+-   `global.d.ts` is where we extend Cypress types
+-   `API.ts` contains api requests for common actions (great place for cleanup actions)
+-   `UI.ts` contains common functions for UI operations
+-   `commands.ts` is the place to map the functions to a cypress command
+
+### Test Format
+
+Ideally each test should manage its own data.
+
+Avoid using `after` and `afterEach` hooks for cleaning up. According to Cypress docs, there is no guarantee that the functions will run
+
+Suggested Format:
+
+-   `prepare`
+-   `when`
+-   `then`
+-   `clean`
+
+#### Passing (returned) parameters around
+
+```ts
+it('can add, update and delete a gradual rollout strategy to the development environment', async () => {
+    cy.addFlexibleRolloutStrategyToFeature_UI({
+        featureToggleName,
+    }).then(value => {
+        strategyId = value;

+            () => cy.deleteFeatureStrategy_UI(featureToggleName, strategyId)
