testing spring boot rest application with restAssured

Question

I've been struggling with this for some time now. I'd like to use restAssured to test my SpringBoot REST application.

While it looks like container spins up properly, rest assured (and anything else seems to have problems reaching out to it.

All the time I'm getting Connection refused exception.

java.net.ConnectException: Connection refused

at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350)
at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206)
at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188)
at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392)
at java.net.Socket.connect(Socket.java:589)
...

my test class:

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class SizesRestControllerIT {

    @Autowired
    private TestRestTemplate restTemplate;

    @Test
    public void test() {
        System.out.println(this.restTemplate.getForEntity("/clothes", List.class));
    }

    @Test
    public void test2() throws InterruptedException {
        given().basePath("/clothes").when().get("").then().statusCode(200);
    }

}

and now for the weird part, test passes and prints what it should, but test2 is getting Connection refused exception.

Any ideas what is wrong with this setup?

Answer 1

I'll answer this question myself..

After spending additional amount of time on it it turned out that TestRestTemplate already knows and sets proper port. RestAssured does not...

With that I got to a point where below test runs without any issues.

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class SizesRestControllerIT {

    @LocalServerPort
    int port;

    @Before
    public void setUp() {
        RestAssured.port = port;
    }

    @Test
    public void test2() throws InterruptedException {
        given().basePath("/clothes").get("").then().statusCode(200);
    }

}

I could have sworn I tried doing it this way previously... But I guess I did use some other annotations with this...
