java - 测试失败时 Rest Assured Exception

Question

我有一个简单的放心测试，用于验证此 json 是否包含正确的调用数据。由于 2 个不同版本的 ASM 的已知问题，我正在使用放心的 1.8 并确实将 groovy jar 换成了 groovy-all jar。

我返回的 json 看起来像这样:

{"account":"12345"}

我的代码是这样的:

package com.blah.tests;

import org.junit.Test;
import static com.jayway.restassured.RestAssured.given;
import static org.hamcrest.Matchers.equalTo;

public class AccountsTest {

public AccountsTest() {
}


@Test
public void getLocationAccount() {

            given().
                param("thingAccountIsfor","ABCD").
            expect().
                statusCode(200).
                body("account",equalTo("10")).
            when().
                get("http://machine:2343/rest/accounts/getaccount");

    }

}

当我运行此匹配我期望的帐户值时，它工作正常。当我输入一个不匹配的值时，我得到一个堆栈跟踪:

log4j:WARN No appenders could be found for logger (org.apache.http.impl.conn.SingleClientConnManager).
log4j:WARN Please initialize the log4j system properly.

java.lang.AssertionError: 1 expectation failed.
JSON path account doesn't match.
Expected: 10
  Actual: 12345

Process finished with exit code 255

我在 Intellij 中运行它。我确实尝试将 groovy jar 移回原处，将冲突版本的 ASM 移出我的类路径并重新运行它。我得到了相同的结果，所以我不认为这与使用 groovy-all jar 而不是随 rest-assured 1.8 一起提供的 groovy jar 有关。

rest-assured 是每次测试失败都会抛出异常还是这里有问题？

Answer 1

是的，它会因抛出 AssertionException 而失败。您有两种方法可以避免这种情况:

1. 使用 AssertionError 捕获异常。

2. 删除 expect().statusCode().body() 部分并将响应分配给 Response 对象，并通过使用 JsonPath 对象解析它来继续进行所需的测试如下所示。

   Response res = given().
       param("thingAccountIsfor","ABCD").       
       when().
       get("http://machine:2343/rest/accounts/getaccount");
   JsonPath jp = new JsonPath(res.asString());
   String account = jp.get("account").toString();
