Performing end-to-end integration tests

Now, we've finished both the register and login feature of the User module. It's time to work on the end-to-end test now. Before we continue, let's review our current end-to-end test. By now, we only have a very basic login.e2e.js, which only tests against http://localhost:3000 and does not use Page Objects. In this section, we will make the following improvements to our end-to-end test:

• Correct the port so that tests can be run against http://localhost:8080 during a Maven build
• Use Page Objects in tests
• Automatically generate a user's test data, which can be shared across tests
• Execute multiple tests in a specific order

Let's go through these one by one.

Correcting the port

In order to run the test against the URL through port 8080, we will need to ask @vue/cli-service to not start the dev server by providing a --url parameter to the command, like the following:

"scripts": {
  ...
  "test:e2e": "vue-cli-service test:e2e",
  "test:integration": "vue-cli-service...
