⚠️⚠️ Archive ⚠️⚠️

Unfortunately we never got this project running on a production level. In the meanwhile we have decided to use Maestro for mobile E2E testing and absolutely love it. You can check out our progress here.

Run Detox in CI with EAS build

This project includes example workflows for showing how to run detox tests in a CI environment with Github Actions.

Prerequisites

• You use eas build from expo to run your app builds

Commands

# Run build for simulator
eas build --platform ios --profile development-sim

# Run detox tests
yarn detox test --configuration ios

Trigger CI workflow via EAS Build webhooks

To avoid a long running workflow, we trigger the tests to run whenever we receive a webhook from EAS Build telling us that our build is finished.

Here is an example in Node.js using Express.js for how we can accept EAS Build webhooks and trigger our detox test run workflow within Github Actions:

const express = require('express');
const crypto = require('crypto');
const safeCompare = require('safe-compare');
const bodyParser = require('body-parser');
const axios = require('axios');

const app = express();
app.use(bodyParser.text({ type: '*/*' }));

app.post('/', async (req, res) => {
  const expoSignature = req.headers['expo-signature'];

  if (!isSignatureValid(expoSignature)) {
    res.status(500).send("Signatures didn't match!");
  }

  const downloadUrl = req.body.artifacts.buildUrl;

  try {
    const response = await triggerGithubWorkflow(downloadUrl);
    console.log(response);
  } catch (e) {
    console.error(e);
    res.status(500).send(e.message);
  }

  res.status(200).send('success');
});
exports.handleWebhook = app;

async function triggerGithubWorkflow(downloadUrl) {
  const githubApi = axios.create({
    baseURL: 'https://api.github.com/repos/',
    timeout: 2000,
    headers: {
      authorization: 'Bearer ' + process.env.GITHUB_ACCESS_TOKEN,
    },
  });

  const response = await githubApi.post(
    process.env.GITHUB_USER +
      '/' +
      process.env.GITHUB_REPO +
      '/actions/workflows/' +
      process.env.WORKFLOW_FILE_NAME +
      '/dispatches',
    {
      ref: 'master',
      inputs: {
        downloadUrl,
      },
    }
  );
  return response;
}

function isSignatureValid(expoSignature) {
  const hmac = crypto.createHmac('sha1', process.env.SECRET_WEBHOOK_KEY);
  const hash = `sha1=${hmac.digest('hex')}`;

  return safeCompare(expoSignature, hash);
}
