+<h1>Nested component testing</h1>
+
+> Author: Thomas Laforge
+
+### Statement:
+
+We have a small application that send a title to a fake backend that you type inside a input.
+If the title is correctly typed, you can send the request otherwise you get a nice error and the request is not sent.
+You can play with it by running : `npx nx serve testing-nested`.
+
+The goal is to test this behavior with Testing library and Cypress
+
+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](https://marketplace.visualstudio.com/items?itemName=firsttris.vscode-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.
+
+I created some `it` blocks but feel free to add more test if you like to.
+
+### Submitting your work
+
+1. Fork the project
+2. clone it
+3. npm install
+4. `npx nx serve testing-nested` to play with the application
+5. `npx nx test testing-nested` to test your application with Testing Library
+6. `npx nx component-test testing-nested --watch` to test your application with Cypress
+7. _...work on it_
+8. Commit your work
+9. Submit a PR with a title beginning with **Answer:18** that I will review and other dev can review.
