Hamcrest 匹配器 closeTo 无法按预期工作

Question

我正在使用 Spock 和 RestAssured 对休息服务执行一些集成测试。我在使用 hamcrest 的 closeTo 匹配器检查双精度值时遇到问题：

class PlaceITSpec extends Specification {
 def "Create a Place"() {
    given:
        def place = ['name' : 'Depot A',
                    'location': [
                            'latitude': 40d,
                            'longitude': -3d
                    ]]
        def request = given().accept(ContentType.JSON).contentType(ContentType.JSON).body(place)

    when: "POST /places"
        def response = request.with().post("http://localhost:8080/places")

    then: "I get a the created place resource and 201 status code"
        response.then().log().all()
                .statusCode(201)
                .body("name", equalTo(place['name']))
                .body("location.longitude", is(closeTo(place['location']['longitude'], 0.000001d)))
                .body("location.latitude", is(closeTo(place['location']['latitude'], 0.000001d)))
                .body("_links.self", notNullValue())
                .body("_links.place", notNullValue())

  }
}

测试失败：

java.lang.AssertionError: 1 expectation failed.
JSON path location.longitude doesn't match.
Expected: is a numeric value within <1.0E-6> of <-3.0>
  Actual: -3.0

一切似乎都很好。试图丢弃明显的错误，我使用了错误值 1。但是测试失败了：

java.lang.AssertionError: 1 expectation failed.
JSON path location.longitude doesn't match.
Expected: is a numeric value within <1.0> of <-3.0>
  Actual: -3.0

我想我做错了什么。有人遇到同样的问题吗？

Answer 1

终于通过RestAssured doc

找到了正确答案

Floating point numbers must be compared with a Java "float" primitive

我将代码更新为：

class PlaceITSpec extends Specification {
def "Create a Place"() {
given:
    def place = ['name' : 'Depot A',
                'location': [
                        'latitude': 40f,
                        'longitude': -3f
                ]]
    def request = given().accept(ContentType.JSON).contentType(ContentType.JSON).body(place)

when: "POST /places"
    def response = request.with().post("http://localhost:8080/places")

then: "I get a the created place resource and 201 status code"
    response.then().log().all()
            .statusCode(201)
            .body("name", equalTo(place['name']))
            .body("location.longitude", equalTo(place['location']['longitude']))
            .body("location.latitude", equalTo(place['location']['latitude']))
            .body("_links.self", notNullValue())
            .body("_links.place", notNullValue())

  }
}

检查纬度和经度值现在是否具有 f 后缀以指示 float 原语不是 double 原语。并且还将 is(closeTo(data,error)) 更改为 equalTo(data)
