Performance Test Suite

Repository for performance testing includes Jmeter .jmx files for all types of load testing as well as code for streaming client.

Streaming Client

Pre-requisites

  • Install node on your MAC OS machine, run this command : brew install node@16
  • Verify the installation using this command : node --version

Getting Started

  • After node is installed , you can put the audio(.wav) file on which you want to run the test inside the streaming folder.

  • As of now we are using audiosample.wav as the audio file.

  • The configuration variables like streaming_server_url, audio_file_path, timeout are available in the streaming/config.js. Please do configure as per your requirements.

  • Once you are ready with the configurations, go to location using the command : cd ./streaming/src/.

  • To do a sample run, execute the following command :

    lang=en node application.js <absolute path to audio .wav file>

Note: lang param is used to define the audio language for which you want to run the test suite.

In logs you should be able to see input audio split into 5 chunks (as per the current audio file and config) and its respective responses. Verify that the Execution time given in logs is equal to the audio duration.

Configuration settings

  • If you wish to change the audio file, you need to change the chunk size and timeout in config file (streaming/config.js).
  • Logical explanation is explained in the config file.

  • Once the setup is done, you can run it by clicking on the run button.
  • You can see the report in the aggregate Report after the test.

How to Run other suites using Jmeter

  • Open Jmeter on your machine
  • For ASR Batch API - use ASR.jmx.
  • For TTS API - use TTS.jmx.
  • You can configure the URLs , Total Test time, ramp up time in Jmeter on Thread Group of all languages.
