I am trying to write a JUnit test, which checks the value of received JSON. I access these values in the JSON using jsonPath. I want to check if a value is true. For simple jsonPaths, it works for me, but when I write more complex jsonPath query, it does not and I am getting this Assertion Error:
Expected: is <true>
but: was <[true]>
My JSON:
{...
,"trips":
[
{...
,"employee":{"name":"Ordinary Joe","login":"joe","contractor":true}
,...
},
...
],
...
}
Problematic assertion
.andExpect(jsonPath("$.trips[?(@.employee.login=='joe')].employee.contractor", is(true)));
What I've tried
I tried to match the value also with new Boolean(true), boolean[] array with one true value and after examination of is() matcher also with String.valueOf(true) however it also did not match.
My question
How should I correctly match this true value? What exactly these [] braces mean in the test output?
In the further investigation, I actually found that jsonPath somehow converts the obtained true value to a JsonArray with one item and therefore it is not possible to match it with is(true) matcher. I am not sure why JsonPath does so.
I found the following working workaround using hasItem matcher instead:
.andExpect(jsonPath("$.trips[?(@.employee.login=='joe')].employee.contractor", hasItem(true)))
.andExpect(jsonPath("$.trips[?(@.employee.login=='joe')].employee.contractor", not(hasItem(false))))
