Taurus is an open source test automation tool that extends and abstracts leading open source tools including JMeter, Gatling, Locust.io, The Grinder, JUnit, Selenium, and more. Taurus provides a simple way to create, run, and analyze performance tests.
Taurus can consume configuration files written in JSON or YAML languages, which are very human-readable. For instance, a simple load test with 10 concurrent users, a ramp-up time of 1 minute, a duration of 2.5 minutes and hitting the site blazedemo.com with HTTP GET requests will look as simple as:
execution:
concurrency: 10 hold-for: 2m30s ramp-up: 1m scenario: Thread Group
scenarios:
Thread Group:
requests:
- label: blazedemo
method: GET
url: http://blazedemo.com/
As you can see, it’s only eleven lines of simple human-readable language that represents a (more or less) complete load scenario. It’s really simple to use.
This is the whole idea of Taurus: to provide a unified, simplified way of configuring and running automated tests, then present the results in the most effective form.

Creating a New Taurus Test in BlazeMeter
You can start creating your Taurus test in the BlazeMeter GUI by clicking on the Perfomance section, then the "Create Test" button on the top navigation bar, then clicking the "Performance Test" button, as detailed in our New Test Create Screen guide (also, see the screenshot below):
CAUTION! Though Taurus supports Selenium scripts, we do not recommend running Selenium tests as performance tests, as explained in our KB article Can I use Selenium for Load Testing? We recommend using Selenium tests for functional testing instead, as detailed in our guide Creating a GUI Functional Test.
Upload a YAML/JSON Script with Test Assets
At the top of the screen, you'll find a central location to upload your YAML/JSON script. Here, you can either click the "+" button to browse to your script or drag the script from your desktop to the "+" button.
Note: Taurus' included-configs setting is not supported in the Blazemeter cloud. If your YAML references a secondary YAML via included-configs for additional configuration settings, please merge all settings into one YAML before uploading your test.
For more details about this stage of test creation, please refer to our detailed Scenario Definition guide, and for more information regarding uploading files to the test configuration page, please refer to our Uploading Files & Shared Folders guide.
After uploading your YAML file, you may notice that some options disappear from the UI as a result -- namely Load Configuration and Load Distribution options. That's because when you're running a Taurus test, these settings must be configured directly via the YAML, not via the UI, unlike other test types. (For details on how to do this, refer to Taurus's guide on how to configure a Load Profile.)
Note: Taurus uses some different terminology for some settings. The "Hold-for" setting in a Taurus YAML is the equivalent of the "Duration" setting in the Load Configuration section of BlazeMeter's UI.
Under the 'Configuration Preview', you will see the YAML/JSON code of the file you uploaded.
If you're running a JMeter test with Taurus and have uploaded a CSV file with your script, then the option to "split CSV files" appears below the script preview. You may check this box to enable the feature, which you can learn more about here.
There are additional options you can add to your test configuration, and we have a detailed guide on each topic, including:
All done? Now just give it a name and you're Taurus test is ready to go!
Note: An alternative method is to call Taurus from the command line, then have the test run in BlazeMeter automatically by adding "provisioning: cloud" to the configuration. This method doesn't even require a web browser! To learn more about this alternative method, check out the Taurus documentation on the topic here.
Ready to Run!
You can now either run the test or run a debug of the test (to learn more about the debug option, please refer to this article).
Once again, make sure you name your test, save it, and then you're ready to go! Great! You've now successfully set up your Taurus test. Ready to move on to the next step? Read our article on Running BlazeMeter Tests to find out how.
