Assert that response body is empty list with rest-assured

The problem is (probably) that REST Assured returns a List and not an array (and Hamcrest differentiate between the two). You can do:

.body("", Matchers.hasSize(0))

.body("$", Matchers.hasSize(0))

.body("isEmpty()", Matchers.is(true))

Inspired by what @Johan said I tried this and I think it tells more to reader than other suggestions.

.body("", equalTo(Collections.emptyList()))
