Rest保证允许编写RESTendpoint的测试。它具有的有用功能之一是能够在测试失败的情况下记录请求和响应，以便您可以检查发送到REST服务的内容。

记录请求和响应的失败测试示例

import io.restassured.RestAssured;
import org.junit.Before;
import org.junit.Test;

import static io.restassured.RestAssured.*;
import static org.hamcrest.Matchers.*;

public class TestRestAssured {
  @Before
  public void setUp() {
    RestAssured.enableLoggingOfRequestAndResponseIfValidationFails();
  }

  @Test
  public void exampleFailingTest() {
    String json = "{\n" +
        "  \"title\": \"foo\",\n" +
        "  \"body\": \"bar\",\n" +
        "  \"userId\": 1\n" +
        "}";
    given()
        .contentType("application/json; charset=UTF-8")
        .body(json)
        .post("http://jsonplaceholder.typicode.com/posts")
        .then()
        .body("userId", equalTo(2));
  }
}

此测试失败，因为返回的userId为1。这是执行测试时在控制台上打印的内容。

    "title": "foo",
    "body": "bar",

{
    "title": "foo",
    "body": "bar",
    "userId": 1,
    "id": 101
}

java.lang.AssertionError: 1 expectation failed.
JSON path userId doesn't match.

  Actual: 1

这是一个很棒的功能，因为它允许报告更有上下文的bug报告。在引擎盖下，它使用LogConfig，您可以将其配置为写入任何默认为System. out的PrintStream。

Maven Surefire插件在两个文件（文本和XML）上报告错误。但是在这些文件上，它只包括测试方法抛出的异常中的内容。所以报告中的细节如下所示：

java.lang.AssertionError: 1 expectation failed.
JSON path userId doesn't match.
Expected: <2>
  Actual: 1

    [rest of the stacktrace]

这很好，但还可以更好。

现在应该很明显了。

如何在Surefire报告中包含来自REST保证的请求和响应详细信息？
