How to set up and validate locally

Numbered steps to set up and validate the change are strongly suggested.

Create the pre-scan verification records

1. Start the rails console

rails c

2. Create the records

dpsv = dpsv = Dast::PreScanVerification.create(dast_profile: Dast::Profile.last, ci_pipeline: Ci::Pipeline.last)

Dast::PreScanVerificationStep.create(name: 'connection', dast_pre_scan_verification: dpsv)

Dast::PreScanVerificationStep.create(name: 'authentication', dast_pre_scan_verification: dpsv, verification_errors: ['Actionable error message'])

Dast::PreScanVerificationStep.create(name: 'crawling', dast_pre_scan_verification: dpsv)

Query the pre-scan verification

1. Go to /-/graphql-explorer
2. Add a Query like

{
  project(fullPath: "root/apiscantest") {
    dastProfiles {
      nodes {
        dastPreScanVerification {
          status
          valid
          preScanVerificationSteps {
            name
            errors
            success
          }
        }
      }
    }
  }
}

3. Check the results

{
  "data": {
    "project": {
      "dastProfiles": {
        "nodes": [
          {
            "dastPreScanVerification": null
          },
          {
            "dastPreScanVerification": {
              "status": "COMPLETE_WITH_ERRORS",
              "valid": true,
              "preScanVerificationSteps": [
                {
                  "name": "connection",
                  "errors": [],
                  "success": true
                },
                {
                  "name": "authentication",
                  "errors": [
                    "Actionable error message"
                  ],
                  "success": false
                },
                {
                  "name": "crawling",
                  "errors": [],
                  "success": true
                }
              ]
            }
          }
        ]
      }
    }
