JMeter<\/a> extends the useful capability to extract response data into user variables. In a recent post, we covered how to use the Page Data Extractor<\/em><\/a> to find and save data metrics returned in the body of the page for use in post-processor scripts<\/a> and other test plan elements. It is a reasonable requirement to see if such extractions are successful before proceeding to this other test logic, which can be achieved manually in your scripts. However, in this post we will review how to use the Extractor Success Assertion<\/em><\/a> component to automatically check if an extractor successfully returned data from the request.<\/p>\n

<\/a>Adding the Extractor Success Assertion<\/h3>\n

The Extractor Success Assertion<\/em> plugin must be added to JMeter via the Plugins Manager<\/em><\/a>, which can be found under the \u201cOptions<\/em>\u201d menu. Installing the plugin for the first time will require a restart of JMeter:<\/p>\n

The Extractor Success Assertion plugin can be installed from the JMeter Plugins Manager.<\/figcaption><\/figure>\n

<\/a>Configuring the Extractor Success Assertion<\/h3>\n

It is recommended per the documentation<\/a> that the Extractor Success Assertion<\/em> is added as a top-level component in your test plan:<\/p>\n

Extractor Success Assertion as top-level component in the test plan.<\/figcaption><\/figure>\n

A single instance of this component can be used for all extractors in your test. It accepts a comma-separated list of extractor variable names, as shown below where we have specified \u201cMY_VARIABLE<\/strong><\/code>\u201d as a configured option:<\/p>\n

Configuring the Extractor Success Assertion plugin.<\/figcaption><\/figure>\n

Upon execution, this assertion will serve to fail the current iteration of the test plan in the event that an extractor fails to capture any of the specified user variables. Using this component, your test results can be assured free of spurious results due to extractors that fail to capture their intended targets, without the need to code checks for each of these variables individually in your post-processor scripts.<\/p>\n
