Let’s first imagine a scenario: when technical personnel complete development, how do their customers, product managers, or testers determine the usability of the product? Generally, they perform the following steps for testing:

Open the browser;

Enter the url;

See some information and confirm that this page is available;

Click on a certain url;

Fill in the form, submit the form, see some information, and determine that this function is available

This testing method is called manual testing, or manual testing, which is the opposite of it It is an automated test. Codeception's Acceptance Tests will use the browser's programming interface to completely automate the steps involved in the above manual testing, greatly saving labor costs.
