Why is automated testing important? Select all that apply.

• It reduces human error.

• It offers a faster feedback cycle, bringing faster validation and helping the development team to detect problems or bugs early.

• It saves time to development teams.

What are some of the best practices when writing your automated tests? Select all that apply

• They should resemble the way your software is used.

• They should be maintainable in the long run.

• Your tests need to be focused on the implementation details of your components.

Imagine you have a component that renders both an input tag and a label tag with the exact text Comments:. Inside your test, you have the below piece of code:

 const element = screen.getByLabelText(/Comments:/);

• The label element

• The input element

• The document object

In a particular test that’s been written for a form component, you encounter the below two lines of code. What kind of data would the handleSubmit variable represent?

 const handleSubmit = jest.fn();
 render(<FeedbackForm onSubmit={handleSubmit} />);

• A copy of the real function that’s used in the parent component that renders the FeedbackForm.

• A mock function to track how is called by external code and thus explore the arguments passed in.

• A specific function jest provides to handle form submissions

What are some of the benefits of Continuous Integration (CI)? Select all that apply.

• Find bugs earlier and fix them faster.

• Improved developer productivity.

• Faster manual integrations.

• Deliver working software more often.
