What is Angular E2E Testing and how do I implement it?

Angular E2E Testing, or end-to-end testing, is a testing methodology that evaluates the entire application flow. It ensures that all components work together as expected. You can implement it using tools like Protractor or Cypress.

Can you give me a basic example of an E2E test in Angular?

Sure! Here's a simple example using Protractor:

describe('My Angular App', () => {
  it('should display the title', () => {
    browser.get('http://localhost:4200');
    expect(browser.getTitle()).toEqual('My Angular App');
  });
});

What are some best practices for writing E2E tests?

Some best practices include:

1. Keep tests independent and isolated.
2. Use descriptive names for your tests.
3. Avoid hardcoding values; use variables instead.
4. Regularly run your tests to catch issues early.

How do I set up Protractor for my Angular project?

To set up Protractor, first install it via npm:

npm install --save-dev protractor

Then, update your protractor.conf.js file with your test specifications and run it using:

protractor protractor.conf.js
