Mochawesome/Testomatio/junit reporter: run-workers: Running of test with --suite doesn't aggregate results from all suites per browser

Comienza con codecept.conf.ts y reproduce el problema usando codeceptjs run-workers 3 dev --by suite --reporter mocha-multi contra SuiteA_test.ts y SuiteB_test.ts. Rastrea cómo llegan los resultados de los workers a las rutas de salida configuradas de Mochawesome y mocha-junit-reporter; se considera terminado cuando los artefactos console.log, HTML, JSON y XML tanto de chromium como de firefox contienen ambas suites.

The issue is even in older versions, e.g. in 3.5.3. Retested with the latest 3.7.6 and the issue persists.

• npm i mochawesome
• npm i mocha-junit-reporter
• npm i mocha-multi
• Run the tests codeceptjs run-workers 3 dev --by suite --reporter mocha-multi (parallelization per browser and per suite). Another variant is --suites instead of --by suite, but it behaves the same way.

$ codeceptjs run-workers 3 dev --by suite --reporter mocha-multi
CodeceptJS v3.7.6 #StandWithUkraine
Running tests in 3 workers...

[Worker 03]   ✔ SuiteB › Scenario 1 in 4ms
[Worker 03]   ✔ SuiteB › Scenario 2 in 1ms
[Worker 01]   ✔ SuiteA › Scenario 1 in 5ms
[Worker 01]   ✔ SuiteA › Scenario 2 in 1ms
[Worker 02]   ✔ SuiteA › Scenario 1 in 3ms
[Worker 02]   ✔ SuiteA › Scenario 2 in 1ms
[Worker 04]   ✔ SuiteB › Scenario 1 in 4ms
[Worker 04]   ✔ SuiteB › Scenario 2 in 1ms

  OK  | 8 passed   // 3s

Expected result:

• output/console.log contains data from both test suites
• output/dev_chromium1/report.html contains data from both test suites
• output/dev_chromium1/report.json contains data from both test suites
• output/dev_chromium1/result.xml contains data from both test suites
• output/dev_firefox1/report.html contains data from both test suites
• output/dev_firefox1/report.json contains data from both test suites
• output/dev_firefox1/result.xml contains data from both test suites

This way it works with run-multiple (parallelization per browser, but test suites are run in sequence) ✔️

Actual result:

• All the mentioned files contains data from the SuiteA only. The SuiteB is missing there 🐞 . A problem seems to be that test suites overwrite each other's results when running in threads.

Config codecept.conf.ts:

import { setHeadlessWhen, setCommonPlugins } from "@codeceptjs/configure";
// turn on headless mode when running with HEADLESS=true environment variable
// export HEADLESS=true && npx codeceptjs run
setHeadlessWhen(process.env.HEADLESS);

// enable all common plugins https://github.com/codeceptjs/configure#setcommonplugins
setCommonPlugins();
