Run fault Scenarios

In this guide, you will learn how to run fault scenarios and read the generated report.

Prerequisites

  • Install fault

    If you haven’t installed fault yet, follow the installation instructions.

  • Generate Scenario Files

    If you haven’t created a scenario file, please read this guide.

Run a Scenario File

We will explore now how to run scenarios generated to verify the resilience of the fault demo application itself.

  • Start demo application provided by fault

    fault demo run  # (1)!
    1. The application under test must be started for the scenario to be meaningful. Otherwise, the scenarios will all fail.

  • Run a scenario file

    fault scenario run --scenario scenario.yaml

Run Many Scenario Files

We will explore now how to run scenarios generated to verify the resilience of the fault demo application itself. In this specific use case, we assume you want to run many scenario files at once and that they are located in the same directory.

  • Start demo application provided by fault

    fault demo run  # (1)!
    1. The application under test must be started for the scenario to be meaningful. Otherwise, the scenarios will all fail.

  • Run scenario files located in a directory

    fault scenario run --scenario scenarios/  # (1)!
    1. fault will load all YAML files in that directory.
