API測試-在對JSON使用restassured時導致方括號中的值導致斷言失敗

Question

我是新來的放心的人。 我正在嘗試使用以下API來獲取json響應並驗證“資本”是否為“奧斯陸”。

但是每次斷言都會失敗，因為該值被提取為[Oslo]而不是Oslo

響應JSON：

[
  {
    "name": "Norway",
    "topLevelDomain": [
      ".no"
    ],
    "alpha2Code": "NO",
    "alpha3Code": "NOR",
    "callingCodes": [
      "47"
    ],
    "capital": "Oslo",
    "altSpellings": [
      "NO",
      "Norge",
      "Noreg",
      "Kingdom of Norway",
      "Kongeriket Norge",
      "Kongeriket Noreg"
    ],
    "relevance": "1.5",
    "region": "Europe",
    "subregion": "Northern Europe",
    "population": 5176998,
    "latlng": [
      62,
      10
    ],
    "demonym": "Norwegian",
    "area": 323802,
    "gini": 25.8,
    "timezones": [
      "UTC+01:00"
    ],
    "borders": [
      "FIN",
      "SWE",
      "RUS"
    ],
    "nativeName": "Norge",
    "numericCode": "578",
    "currencies": [
      "NOK"
    ],
    "languages": [
      "no",
      "nb",
      "nn"
    ],
    "translations": {
      "de": "Norwegen",
      "es": "Noruega",
      "fr": "Norvège",
      "ja": "ノルウェー",
      "it": "Norvegia"
    }
  }
]

我的代碼：

public class RestTest {

@Test
public void getRequestFindCapital() throws JsonException {

    given().when().get("http://restcountries.eu/rest/v1/name/norway")
            .then()
            .statusCode(200)
            .body("capital", equalTo("Oslo"));
}

我得到的斷言失敗是：

java.lang.AssertionError: 1 expectation failed.
JSON path capital doesn't match.
Expected: Oslo
Actual: [Oslo]

Answer 1

這是因為如果您查看json的頂部，那么這里的所有內容都包含在數組中。 （因此在方括號中）。

雖然有點煩人，但它會像這樣返回。 一個簡單的解決方法是使用類似以下的內容：

body("capital", hasItem("Oslo"))
