Hello, When I am writing tests using Mocketry's DSL, I get puzzled about how / when to use #where, and how is it different when it's used and when it is not? As far as i tried, I did not find any difference. That is, pasting part of one of my tests: response := znClient username: (self uidy: 'Q7') asString, '/TEST' password: 'tk'; timeout: 1; post; response. response should be isSuccess. response where contentType should equal: ZnMimeType applicationJson. response where entity should not be: nil. (STON fromString: response entity contents) should equal: nil I get the same result (pass if ok, failure with DNU when thing is not present) whether `where` is there or isn't. Could you explain what is it's purpose and correct usage? Thanks, Herby
