Put an assertion

in the respense you need to get type=1 for this test case to pass.

Right click on the Test plan and from the assertion list select Response Assertion.

From the response select - “type”:1 and add this to the response assertion.

Now run the test plan again.

You can also add an assertion listener to see the assertion results.then run it again.
