Jmeter正则表达式错误

Question

I have a problem with jmeter regular expressions extractor. I'm using magento jmeter stress test. https://github.com/magento/magento-performance-toolkit/tree/master/1.14

Problem is in next part. When i put category url and key in settings, jmeter gives me next errors:

Assertion error: false
Assertion failure: true
Assertion failure message: Response was null

This is regular expression extractor:

<a href="http://${host}${base_path}(index.php/)?([a-z0-9-]+)${url_suffix}" class="level

This if from responce assertion:

^[a-z0-9-]+$

Example of url: http://web.stresstest.com/index.php/my-class.html

Answer 1

The error you're getting is due to a Null response , meaning you didn't get a checkable response.

Could you show the Sampler details and in View Results Tree the request and response ?
