  "reporter-option": [
    `apiKey=${process.env.TESTREAM_API_KEY}`,
    "uploadEnabled=true",
    "failOnUploadError=false",
    `buildName=${process.env.GITHUB_WORKFLOW || "mocha-tests"}`,
    `testEnvironment=${process.env.TEST_ENV || "ci"}`,
    `appName=${process.env.APP_NAME || "my-app"}`,

Notes

• The reporter writes the CTRF report to ctrf/ctrf-report.json.
• Git and CI metadata can be auto-detected when running in supported CI providers.
• Mocha passes reporter options as strings (key=value), including booleans.
