Introduction to BlazeMeter and Taurus

BlazeMeter: Platform for executing load tests at scale

Cloud-based load generators

Intuitive reporting

Open Source DNA

Taurus: Open Source Test Development and Execution

Execute existing open source load test scripts: JMeter / Selenium / Gatling / etc…

and / or

Define tests in a YAML-based domain-specific language designed for load testing

and / or

Combine the two methods for complex parallel test runs

Test Development: Record with BlazeMeter Extension

Works with Google Chrome Web Browser and BlazeMeter Account

Easy to Install, Easy to Use

Click the Record Button to Start Capture

Captures All Requests from the Browser, Including AJAX

Navigate Through the App to Build the Test Plan

Stop Recorder and Save Recordings as JMX (or Taurus YAML)

Test Development: Modify the JMeter Script

Clean Up Extraneous Requests

Parameterize the Script

Replace static post data with ${variables}

Include a CSV file to populate the variables

Each thread or iteration will use different values.

Use Post Processors to Capture Session Tokens

Test Script Against an Instance of the App

Test Development: Convert to Taurus

Use jmx2yaml Utility to Convert JMeter files to more readable YAML

Optionally Trim Out Recorded Headers for Additional Readability
