Jmeter Assertion failure reason

Question

I'm running a test on Jmeter. this is part of the sampler result-

Load time: 520
Connect Time: 0
Latency: 520
Size in bytes: 504
Headers size in bytes: 458
Body size in bytes: 46
Sample Count: 1
Error Count: 1
Response code: 201
Response message: Created

so I have added 'Response Assertion' that configured as follows-

Apply to:Main sample only, Response Field to test:Response Code, Pattern Matching Rules:Equals, Patterns to test: 201.

when running it, the request fails and the reason is this:

Assertion error: false
Assertion failure: true
Assertion failure message: Test failed: code expected to equal /

****** received  : 201[[[  ]]]

****** comparison: 201[[[

]]]

/

What is exactly the problem?

I assume that in description you specified

Response Field to test:Response Message

by mistake, since the failure points to the fact that you compared Response code.

Given that, looks like you accidentally have newline character(s) after "201", which is(are) invisible, but cause comparison to fail. So just remove any spaces/newlines after "201". Make sure that Patterns to test is exactly 201, nothing else.
