I want to stop a thread based on the response assertion, but even though the response assertions are triggering, they are not failing the sample:
As you can see, the first 2 are not failing the sample, but the 3rd one('This page is no longer available'), is failing correctly.
The first 2 assertions are directly on the samples, which are nested under parent controllers, whereas the 3rd assertion is against multiple samples on the level above the bottom simple controller:
Note. If I move either of the first two assertions to the same level as the third assertion, then they correctly fail the sample. But I don't want that as they are specific to their http requests.
Example of Response Assertion not failing sample at sample level, but working at level above:

I am trying to generate a test report for a thread group.
I see that since i run a http request in while loop controller, the request shows up in the report with too many failures as i also have an assertion to the request.
These are not failures but, tries, how do i make sure that these dont get captured in the report.
I am using View results in table listener for report. I tried to remove assertion for this http request so that it is not captured in the report? Is this the right approach?
As per 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure article:
Use Assertions Sparingly
Every test element added to the test plan will be processed - and this takes CPU time and memory. This also applies to all your Assertions, and is especially true for Compare Assertions - which consumes a lot of resources and memory. Only use the assertions you need and, even then, just use the amount that are absolutely required.
So removing the assertion seems to be a right approach to me.
Also if it's a Response Assertion you can modify it to accept 2 (or more) criteria so you can configure it to not to fail on "tries", example setup which accepts HTTP Status Codes 200 and 501 and will fail for everything else:
I have made a TestPlan in JMeter. I want to test a failure scenario i.e. the test should pass if failure happens. How can I do this in JMeter?
I have added a Thread group, a configuration, an httprequest and a tree listener.
When I run the test (send a signin request of an invalid user), I get ab error from server (200 OK with error message as message body).
I can't find where (and how) I should check the response. Is it in Listeners?
The JMeter builtin solution is Assertions
Assertions are used to perform additional checks on samplers, and are processed after every sampler in the same scope. To ensure that an Assertion is applied only to a particular sampler, add it as a child of the sampler.
In a general case, Response Assertion with your expected text/regex
response assertion control panel lets you add pattern strings to be compared against various fields of the request or response. The pattern strings are:
Contains, Matches: Perl5-style regular expressions
Equals, Substring: plain text, case-sensitive
You also have more specific assertions as JSON Assertion
component allows you to perform validations of JSON documents
JMeter provides Assertions so you can conditionally fail the request if it doesn't contain the data you expect to be there and contains the data which should not be there.
For example this configuration checks the response for absence of error line:

I just did a quick test to run jmeter using Ant. I see an html report that shows success rate based on HTTP status codes:
Ant Jmeter Report
Is it possible to do anything so that say, requests that take more than 1 second are considered as failures too?
So in short I want the report to show failure when the HTTP code is not 2XX and also when response time greater than say 1 sec
Thanks!
In order to check HTTP Status code being 2xx add a Response Assertion to the Sampler(s) which you want to have checked (JMeter Assertions respect JMeter Scoping Rules) and configure it like:
In order to conditionally fail requests which take longer than 1 second add Duration Assertion (the same Scoping Rules apply) and configure it like:
Check out How to Use JMeter Assertions in Three Easy Steps article to learn more how you can conditionally mark JMeter samplers as passed/failed using Assertions.
Add to your test Duration Assertion
with value of 1000
(Milliseconds)
Duration in Milliseconds
The maximum number of milliseconds each response is allowed before being marked as failed.
I am very new to jmeter and have recently started working on it for API load test.
Could someone please explain me why do we need to put assertion in load test, that should have been checked as part of functional test.
Also if I add any assertion as part of my load test it will have an impact on result (avg time, deviation, median etc) which is not correct.
Your thought
The purpose of an assertion on a response would be to insure that you have actually reached the correct destination.
For example if under load you server sends back incomplete responses, or a valid page containing an error message you would never know it without an assertion.
There is always some overhead for processing the assertion, but unless it is performing an excessive number of tests it should be minimal. The assertion is performed on the load generator so if that component cannot handle the additional overhead then the assertions will not be your only concern.
You need to use assertions, but you need to use it carefully. Ensure you use them when required, try to extract as less data as possible.
Follow JMeter tuning tips:
Use Response Assertion or Size assertion, but avoid XML Assertion,
XML Schema Assertion and XPath Assertion
Use Regular Expression Extractor, but avoid XPath Extractor when possible
I have a large test plan with more than 200 tests but there is one thing in common, the API I'm calling for my tests should always return a JSON encoded response.
I'm using ATLANTBH JSON assertion that I can put after each and every test, but is there a way to put an assertion which should be validated for all tests?
Just put it as a child of Thread Group, it will be applied to all requests.
