detox-json-reporter

📊 A lightweight, TypeScript-powered JSON reporter for Detox end-to-end testing with Jest.

Generates structured detox-results.json files for analysis, dashboards (Grafana, Prometheus), or custom test pipelines.

✨ Features

Generates rich JSON reports per test case
Includes timestamps, durations, retries, platform & environment info
Flaky test detection
Works with Detox + Jest seamlessly

🚀 Installation

yarn add -D detox-json-reporter
# or
npm install --save-dev detox-json-reporter

🛠 Usage

➤ Option 1: Use in jest.config.js

Add the reporter to your Jest configuration:

module.exports = {
  reporters: [
    'default',
    ['detox-json-reporter', {
      outputFile: './reports/detox-results.json' // optional path
    }]
  ]
};

This will generate a file at ./reports/detox-results.json after running your Detox tests.

➤ Option 2: Use via Detox config (.detoxrc.js or package.json)

{
  "detox": {
    "testRunner": "jest",
    "runnerConfig": "e2e/config.json",
    "reportSpecs": true,
    "reporter": "detox-json-reporter"
  }
}

This will instruct Detox to use the reporter automatically.
