How to set up and validate locally

Enable FFs

1. In the rails console (rails c) enable the following features:
2. adherence_report_ui (Feature.enable(:adherence_report_ui))
3. compliance_adherence_report (Feature.enable(:compliance_adherence_report, group))

Setup Adherences

1. Visit group settings and enable "Prevent approval by author" from the 'Merge Request Approval' section.
2. This will create a couple of rows inside the project_compliance_standards_adherence table.

Visit Standard Adherence page

1. Visit a group, under Secure (new UI) or Security & Compliance (old UI) > Compliance report

Note: Since 20 max items are displayed on the table, you need to have at least 20 standard adherences in order for pagination to appear - you can either update the GRAPHQL_PAGE_SIZE constant or create a few more projects to trigger additional adherences
