Tests paused
Press [r] to resume testing, [o] Toggle test output, [:] for the terminal, [h] for more options>

Press r to start the continuous testing then press d to open a DEV UI. It will open a new web browser then access to DEV UI.

You’ll also see All tests passed on the right bottom that points the result of the continuous testing.

When you select the down arrow on the left bottom, you will see the readonly log terminal.

Select Continuous Testing menu on the left, you will see the same testing result as you saw in your terminal.

Verify the RESTful API if it works well. For example, use HTTPie to invoke the endpoint in your local terminal:

http :8080/hello

The output should be:

HTTP/1.1 200 OK
Content-Type: text/plain;charset=UTF-8
content-length: 28

Hello from RESTEasy Reactive

You can also use curl command to access the endpoint:

curl localhost:8080/hello

Keep running your Quarkus dev mode!!
