Information

We have a small application that sends a title, typed into an input to a fake backend. If the title is correctly typed, you can send the request otherwise you receive an error and the request is not sent. The application is created with nested components. ChildComponent is the container that includes four components: ResultComponent, ButtonComponent, InputComponent and ErrorComponent. However since we are testing our component as a black box, the architecture of our components doesn’t change anything. You can create your test, change how the components are structured, and your tests should still pass. That’s the goal of integration tests. Never test internal implementation details!!!.

You can play with it by running : npx nx serve testing-nested.

The file named child.component.spec.ts will let test your application using Testing Library. To run the test suits, you need to run npx nx test testing-nested. You can also install Jest Runner to execute your test by clicking on the Run button above each describe or it blocks.

For testing cypress, you will execute your test inside the child.component.cy.ts and run npx nx component-test testing-nested to execute your test suits. You can add the --watch flag to execute your test in watch mode.

Statement

The goal is to test multiple behaviors of the application describe inside each test files using Testing library and Cypress Component Testing.
