json - 如何将 json 中的顶级数组与 specs2 匹配

Question

在 specs2 中，你可以为这样的元素匹配一个数组:

val json = """{"products":[{"name":"shirt","price":10, "ids":["1", "2", "3"]},{"name":"shoe","price":5}]}"""

def aProductWith(name: Matcher[JsonType],  price: Matcher[JsonType]): Matcher[String] =
  /("name").andHave(name) and /("price").andHave(price)

def haveProducts(products: Matcher[String]*): Matcher[String] =
  /("products").andHave(allOf(products:_*))

json must haveProducts(
  aProductWith(name = "shirt", price = 10) and /("ids").andHave(exactly("1", "2", "3")),
  aProductWith(name = "shoe", price = 5)
)

(示例取自此处:http://etorreborre.github.io/specs2/guide/SPECS2-3.0/org.specs2.guide.Matchers.html)

如果 products 是 json 中的根元素，我该如何做同样的事情，即匹配产品的内容？ haveProducts 应该是什么样子？

val json = """[{"name":"shirt","price":10, "ids":["1", "2", "3"]},{"name":"shoe","price":5}]"""

Answer 1

你可以像这样用 have(allOf(products:_*)) 替换 /("products").andHave(allOf(products:_*)) :

val json = """[{"name":"shirt","price":10, "ids":["1", "2", "3"]},{"name":"shoe","price":5}]"""

def aProductWith(name: Matcher[JsonType],  price: Matcher[JsonType]): Matcher[String] =
  /("name").andHave(name) and /("price").andHave(price)

def haveProducts(products: Matcher[String]*): Matcher[String] = have(allOf(products:_*))

json must haveProducts(
  aProductWith(name = "shirt", price = 10) and /("ids").andHave(exactly("1", "2", "3")),
  aProductWith(name = "shoe", price = 5)
)
