Testing your Snyk Connector will require access to the Snyk platform along with a few sample applications imported into your Snyk Environment. The BizDev team at Snyk can provide you with access to a Snyk environment that has a single group and a single organization. You can import the Snyk sample projects to your organization. To configure your GitHub integration in your test environment please see the Snyk Integration documentation.
The quickest and easiest way to get your test environment is to sign up for a free Snyk account. Once you have created your free account, contact the Snyk business development team with the email associated with the account and we will upgrade you to a paid plan for testing.
