Kraken - The Load Testing IDE

Kraken is a load testing IDE based on Gatling.

As such, Kraken provides a complete development environment to software programmers and load testers that seek to make the most out of Gatling:

  • A code editor to create and update .scala Gatling simulations with autocomplete suggestions and code snippets,
  • Simulations debugging and comparison with HAR imports,
  • Load tests analysis with aggregated data in InfluxDb displayed in comprehensive reports generated with Grafana,
  • Multi-hosts load injection using a Kubernetes cluster.

Development

Source code structure

The source code of Kraken is divided in several folders:

  • backend: this folder contains a Gradle multi-modules project that build all Java backends of Kraken,
  • deployment: private Git sub-module used to create and deploy all Docker containers,
  • development: contains shell scripts and docker-compose configuration to start the InfluxDb/Grafana stack in dev mode,
  • documentation: private Git sub-module that builds Kraken's documentation,
  • frontend: this folder contains an Angular project with several libraries and two applications: administration and gatling.

Prerequisites

Run the application from the source code

To run Kraken from the source code, execute one of the following commands from the root folder of the repository:

  • make launch-docker to run the Docker version,
  • make launch-k8s to run the Kubernetes version.

Open the Makefile to know in detail what each of these tasks does.

Tests and bug finders

Frontend

  • ./test-coverage-all to generate test coverage for the complete project,
  • make test APP=<library-or-app> to run tests for a single module (for example make test APP=commons),
  • make lint to run TSLint on the whole project.

Backend

  • make check to run all unit tests and SpotBugs,
  • make test APP=<module-path> to run unit test for a single sub-module (for example make test APP=:commons:docker-client).

Roadmap

Check out the next milestone.
