Run cucumber based cypress feature files in serial processes. (Who knows why i needed this :D)

serial-test.js

#!/usr/bin/env node

/* tslint:disable:no-console */

const proc = require("child_process");
const find = require("find");
const path = require("path");

const projectDirectory = path.resolve(__dirname, "..");

let returnCodeSum = 0

const runFeatureTest = (featureFilename) => {
  return proc.exec(
    `npm t -- --spec ${featureFilename}`,
  );
};

const runFeatureTests = (featureFiles) => {
  const featureFilename = featureFiles.shift();
  if (featureFilename) {
    console.log(`Running Feature File: ${featureFilename}`)
    const process = runFeatureTest(featureFilename);
    process.on('exit', (code) => {
      console.log(`Feature File ${featureFilename} ended with exit code ${code}`);
      returnCodeSum = returnCodeSum + code;
      runFeatureTests(featureFiles);
    });
    process.on('error', (error) => {
      console.log(`${error}`);
    });
    process.stdout.on('data', (data) => {
      console.log(data);
    });
    process.stderr.on('data', (data) => {
      console.error(data);
    })
  } else {
    if (returnCodeSum > 0) {
      console.log(`Exiting with return code 1 because the returnCodeSum was ${returnCodeSum}`);
      process.exit(1);
    }
  }
}

const main = (dir) => {
  console.log("Sequential Test Runner");

  let files = find.fileSync(/\.feature$/, `${dir}/cypress/integration`).sort();

  runFeatureTests(files);
};

main(projectDirectory);
