Assert that response body is empty list with rest-assured
提问by atamanroman
How can I check with rest-assured (2.4.0) if the response json is an empty list?
如果响应 json 是空列表，我如何检查 rest-assured (2.4.0)？
Given the response [](with header content-type=application/json) I tried:
鉴于响应[]（带有 header content-type=application/json），我尝试了：
.body(Matchers.emptyArray()) // expected: an empty array, actual: []
.body("/", Matchers.emptyArray()) // invalid expression /
.body(".", Matchers.emptyArray()) // invalid expression .

The problem is (probably) that REST Assured returns a List and not an array (and Hamcrest differentiate between the two). You can do:
问题是（可能）REST Assured 返回一个列表而不是一个数组（Hamcrest 区分两者）。你可以做：
.body("", Matchers.hasSize(0))
or
或者
.body("$", Matchers.hasSize(0))
or
或者
.body("isEmpty()", Matchers.is(true))

Inspired by what @Johan said I tried this and I think it tells more to reader than other suggestions.
受到@Johan 所说的启发，我尝试了这个，我认为它比其他建议更能告诉读者。
.body("", equalTo(Collections.emptyList()))
