ACS Load Testing is a simple Dockerized application to perform load testing against a web application. It is especially useful for leveraging the power of Azure Container Service to provide significant scalability in your testing.
It utilizes Apache JMeter and Ruby-JMeter to builld containers that will load test your applications.
Lets get started by doing a load test against a blog hosted on github.io.
docker run rgardler/acs-load http://rgardler.github.io
This will make three requests for http://rgardler.github.io. The
output of this command will look something like:
<?xml version="1.0" encoding="UTF-8"?>
<testResults version="1.2">
<httpSample t="332" lt="290" ts="1456740775219" s="true" lb="rgardler.github.io" rc="200" rm="OK" tn="ThreadGroup 1-1" dt="text" by="17329" ng="1" na="1"/>
<httpSample t="57" lt="57" ts="1456740775562" s="true" lb="rgardler.github.io" rc="200" rm="OK" tn="ThreadGroup 1-1" dt="text" by="17328" ng="1" na="1"/>
<httpSample t="55" lt="55" ts="1456740775620" s="true" lb="rgardler.github.io" rc="200" rm="OK" tn="ThreadGroup 1-1" dt="text" by="17328" ng="1" na="1"/>
</testResults>You can save this output to a file with the following command:
docker run rgardler/acs-load http://rgardler.github.io > results.xml
This output can be processed in a number of ways, including loading into a listener in the JMeter GUI or processing with command line tools.
There are a number of optional parameters that can be passed to configure the tests:
| Parameter | Description | Default |
|---|---|---|
| -t or --threads | Number of threads to run concurrently | 1 |
| -l or --loops | Number of times each thread should loop | 3 |
docker build -t rgardler/acs-load .
