This course will provide you with important information, principles, and experience-based advice, to enter the world of testing methodologies. 

Here, you will learn the best practices to follow to write useful and lasting tests, how to test different user flows without a working back-end, how to write effective end-to-end tests (E2E), and how to integrate tests into development and Continuous Integration pipelines.

At the end of the course, you will be able to apply the fundamental principles of the test methodologies to understand what and how to test effectively.

Front-end Testing 101: Integration and End-to-end Testing

# Solution
> Note: You can see the Cypress UI better by opening the link next to **Your app can be found at:**

context("Signup flow", () => {
  it("The happy path should work", () => {
    cy.visit("/register");
    const random = Math.floor(Math.random() * 100000);
    cy.findByPlaceholderText("Username").type(`Tester${random}`);
    cy.findByPlaceholderText("Email").type(`user+${random}@realworld.io`);
    cy.findByPlaceholderText("Password").type("mysupersecretpassword");
    cy.get("form")
      .within(() => cy.findByText("Sign up").click())
    cy.findByText("No articles are here... yet.", { timeout: 10000 }).should("be.visible");

    cy.findByText("Settings").click();
    cy.findByText("Or click here to logout.").click();
    cy.findByText("Sign up").should("be.visible");
  });
});

# Explanation
Here’s an explanation of how the code above works:
- **Line 3:** We visit the `register` page.
- **Line 4-7:** We generate a random `username`, `email` and `password` using the `Math` function. 
- **Line 8-10:** We sign up and check `No articles are here... yet.` to make sure that we are logged in.
- **Line 12-13:** We find the `setting` option and click it. We then click on `Or click here to logout.` to logout.
- **Line 14:** We look for `Sign up` to ensure that we have logged out successfully.
