Java：用于弹簧启动，REST的单元测试用例中的401未经授权的测试用例问题

Question

everyone.

I have written a test case:

AppManagementApplicationTests.java

@Test
public void testWithAppNameAsNull() {

    Input input = new Input();
    // input type
    String inputTrue = input.appNameAsNullOfAppInfo();
    // response has been stored
    Response response = Response.status(401).entity("").build();

    HttpEntity<String> passingData = new HttpEntity<String>(inputTrue);

    ResponseEntity<String> result = this.restTemplate.postForEntity("/App", passingData, String.class);
    assertEquals(response.getStatus(), result.getStatusCodeValue());

}

Input.java

public String appNameAsNullOfAppInfo() {
    String appName = null;
    String appVersion = "1.1";
    String appKey = "testkey";
    long timestamp = 1487076718;

    AppInfo obj = new AppInfo(appName, appVersion, appKey, timestamp);

    Gson gson = new Gson();

    // searialize into string and return
    return gson.toJson(obj);

}

In my code I am sending

return new ResponseEntity(gson.toJson(response), HttpStatus.UNAUTHORIZED);

So when I run it using Postman it gives the status code as 401

But while testing it is giving an error

The URL that I am using is http://localhost:8091/App/ and in the error it is showing http://localhost:41636/App .

And if instead of 401 UNAUTHORISED I change it to 400 BAD_REQUEST, the same test case works absolutely fine. I am not able to figure out why. The line number 139 at which it is showing the error is "ResponseEntity result ="

Thanks in advance.

Answer 1

The url : http://localhost:8091/App/ is your app url defined by your server (Tomcat).

The url : http://localhost:41636/App is the one generated by the embedded server for your test case.. It gets created by the config webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT

Looking at your test, it doesn't look like an authentication issue, but it seems that the inputs parameters passed to your service are incorrect..

Quite a simple solution, just need to add a dependency in my 'pom.xml' file:

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <scope>test</scope>
</dependency>

Now my test case is working absolutely fine.
