I'm trying to use JsonPath to write some unit tests against my webservice apis. I've been trying to write queries using filters to assert on properties of the document. Here are three different examples that I'm struggling with.
@Test
public void testFilterBehavior() {
// What is the expected behavior here? Result seems to be an array, but that
// doesn't work either.
assertThat(json, hasJsonPath("$.actions[?(@.name == 'list:get')].method", is("GET")));
}
@Test
public void testFilterBehaviorAsArray() {
// What is the expected behavior here? Result seems to be an array, but that
// doesn't work either.
assertThat(json, hasJsonPath("$.actions[?(@.name == 'list:get')].method[0]", is("GET")));
}
@Test
public void testFilterBehaviorTryingLast() {
// What is the expected behavior here? Result seems to be an array, but that
// doesn't work either.
assertThat(json, hasJsonPath("$.actions[?(@.name == 'list:get')].method[-1:]", is("GET")));
}
As you can see, I'm trying to write a query matching the action with the name of 'list:get'. The issue is what is returned. It seems as if the query is always returning an array (should it?). Since it's returning an array, I've tried using array index to pull out the result. When I assert without the array dereference, I'm failing because it is saying the results are an array. With the array dereference, I'm failing because it is saying the result is blank.
