在specs2中，您可以为以下元素匹配数组：
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：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？val json = """[{"name":"shirt","price":10, "ids":["1", "2", "3"]},{"name":"shoe","price":5}]"""
最佳答案
您可以这样将/("products").andHave(allOf(products:_*))替换为have(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)
)
