How to use the Duration Assertion to fail a test?

The Apache JMeter Duration Assertion documentation http://jmeter.apache.org/usermanual/component_reference.html#Duration_Assertion 

Definition: The Duration Assertion validates that each response is received within a given amount of time. Any response that takes longer than the given number of milliseconds (specified by the user) is recorded as a failed response.

Parameter Usage
Duration in milliseconds If the requests take longer than ms supplied, Sampler is considered failed
Apply to

  • Main and Sub-Samples
  • Main Samples Only
  • Sub-Samples Only

This is for use with samplers that can generate sub-samples,

e.g. HTTP Sampler with embedded resources

  1. Create your test plan

    • Here is an example which queries 4 URLS
    • Sample JMeter Test with 4 HTTP Samplers

  2. If you want to test performance of a single URL

    • Add duration assertion under the HTTP Sampler
    • Add Duration Sampler

  3. If you want to apply assertion to all Samplers

    • Add duration at same level
    • Duration Example as sibling

  4. Check it locally

    • We will use the single failure case and set it to 10ms, forcing it to fail in every iteration
    • We can see our test failing
    • Duration Assertion with Failure

  5. Run it on RedLine13

    • We can see error log showing output
    • Duration Assertion with Error Table
    • The error requests will display in Error Metrics graphs
    • Duration Assertion with Error graphs
