Building Locally

Before running tests locally you must set an an environment variable called Newtonsoft that contains the your Newtonsoft JSONSchema key. Tests will not execute successfully without this key.

Build Job Details

Before merging to master the semver version attrbutes (major, minor, or patch) must be updated to reflect the type of change made. The publish to NuGet upon merging to master will fail if the version is not updated.


[Dotnet Restore] - Restore 3rd party NuGet packages for all projects [Dotnet Build] - Build all projects in release mode [Run Tests] - Run all tests [Publish] - Publishes QSwagGenerator and QSwagSchema to NuGet if a master branch build


qswag is a Swimlane open-source project; we believe in giving back to the open-source community by sharing some of the projects we build for our application. Swimlane is an automated cyber security operations and incident response platform that enables cyber security teams to leverage threat intelligence, speed up incident response and automate security operations.

You can’t perform that action at this time.
