I'm trying to run the sample code in this book: Building RESTful Web Services with Spring 5 - Second Edition. You can download the sample code for free. In chapter 7, they have some sample code that includes some integration tests and unit tests all in same directory "chapter7ticketmanagement/src/test/java/com/packtpub/restapp/ticketmanagement/". The unit tests work fine. The integration tests fail with "testUsersJsoup(com.packtpub.restapp.ticketmanagement.JsoupUserTest) Time elapsed: 1.011 sec <<< ERROR!
java.net.ConnectException: Connection refused: connect"

I experimented with changing the port from 8080 to 9090 in "ticket-managementsrcmainresourcesapplication.properties" (I also changed the hardcoded values in the integration test) and this did not help.

So "mvn test" produces the above error.
So does running them in spring tool suite.
I edited the original pom.xml and added the "maven-compiler-plugin" to specify java version 1.8. I'm running windows 10.

So the failing code is in "chapter 7ticket-managementsrctestjavacompacktpubrestappticketmanagementJsoupUserTest.java".

Here is the failing code:

public void testUsersJsoup() throws IOException 

 String doc = Jsoup.connect("http://localhost:9090/user").ignoreContentType(true).get().body().text();

 _log.info("test doc : " + doc);

 JsonParser parser = new JsonParser();
 JsonElement userElement = parser.parse(doc);
 JsonArray userArray = userElement.getAsJsonArray();

 _log.info("test size : " + userArray.size());

 assertEquals(4, userArray.size());

HOWEVER, when I type

mvn spring-boot:run

it starts successfully and I point my chrome browser to http://localhost:9090/user (or http://localhost:8080/user if I am using the original code) I see

["userid":100,"username":"David","userid":101,"username":"Peter","userid":102,"username":"John"]

No connection error! The results look correct.

1. We know this is not a firewall problem because it is just with localhost and it works with chrome.


2. There is no proxy involved.


3. I think the ports are correct: I presently have 9090 in the application.properities file, and in the source code and in the browser.


4. "mvn clean" and then "mvn test" again did not help.

There are annotations to start the web app as exemplified here:
Spring Live Lessons Tutorial and they work. See %JAVA_BUILDINGMICROSERVICES%livelessons-securitylivelessons-security-basicsrctestjavabasicBasicSecurityApplicationTests.java.

These annotations have been deprecated, and replaced by newer ones. The problem is that the author of this tutorial is not using theses new annotations correctly: he needs to also use @WebAppConfiguration and this requires some configuration arguments from the @SpringBootTest (which he is missing). Therefor it necessary to manually start the web server with "mvn spring-boot:run" in a separate process and then run the tests.

When I tried to use @WebAppConfiguation, I got other errors. I will document these errors in another post (some day).
