Rest Assured: Extracting value from JSON Array

Question

I am trying to extract values from JSON array with rest assured using jsonPath.

Example JSON Response:

{
    "notices": [],
    "errors": [
        {
            "code": "UNAUTHORIZED"
        }
    ]
}

Current test is below:

@Test(dataProvider = "somePayLoadProvider", dataProviderClass = MyPayLoadProvider.class)
public void myTestMethod(SomePayload myPayload) {
    Response r = given().
            spec(myRequestSpecification).
            contentType(ContentType.JSON).
            body(myPayload).
            post("/my-api-path");

    List<String> e = r.getBody().jsonPath().getList("errors.code");
    assertEquals(e, hasItem(MyErrorType.UNAUTHORIZED.error()));
}

however, i keep getting [] around my error code. I would just like the value.

java.lang.AssertionError: expected 
[a collection containing "UNAUTHORIZED"] but found [[UNAUTHORIZED]]

Expected :a collection containing "UNAUTHORIZED"
Actual   :[UNAUTHORIZED]

Answer 1

Apparently this was just me not using assert() methods correctly.

Changed

assertEquals(e, hasItem(MyErrorType.UNAUTHORIZED.error()));

to

assertTrue(e.contains(MyErrorType.UNAUTHORIZED.error()));

The parsing of the json was done correctly to an ArrayList<String>
