Uncaught TypeError: Cannot read properties of undefined (reading 'length')

[Pverma96]

i am using mocha-multi-reporters in my mocha tests and generating mochawesome and mocha-junit-reports. When using --parallel flag, mocha-junit-reporter throws error:

Uncaught error outside test suite:
Uncaught TypeError: Cannot read properties of undefined (reading 'length')
at isInvalidSuite (node_modules/mocha-junit-reporter/index.js:155:62)
at MochaJUnitReporter._onSuiteBegin (node_modules/mocha-junit-reporter/index.js:232:10)

at ParallelBufferedRunner.emit (node:events:530:35)
at process.processTicksAndRejections (node:internal/process/task_queues:95:5)
at async Promise.allSettled (index 0)

command used to run the tests is:

./node_modules/mocha/bin/mocha.js --config .mocharc.cjs --parallel --reporter mocha-multi-reporters --reporter-options configFile=reporter-config.json --require mochawesome/register --exit test/**/*.spec.js

below is the reporter config file:

{
"reporterEnabled": "mochawesome, mocha-junit-reporter",
"mochawesomeReporterOptions": {
"reportDir": "results/mochawesome",
"overwrite": false,
"html": true,
"json": true,
"toConsole": true,
"consoleReporter": "spec"
},
"mochaJunitReporterReporterOptions": {
"mochaFile": "results/junit/test-results.xml"

}

noticed that if i remove "--require mochawesome/register" flag, i get same error as defined in #178

Version:
"mochawesome": "^7.1.3",
"mocha-junit-reporter": "2.2.0",
"mocha-multi-reporters": "^1.5.1"
"mocha": "^10.4.0",

I'm trying to run tests in parallel as well and getting the a similar issue:

C:\Users\jsmith\git\myProject\node_modules\mocha-junit-reporter\index.js:217
return testsuites[testsuites.length - 1].testsuite;

I followed the documentation and set up my mocha config as follows:

const mochaConfig = {
spec: ['./Axios/tests/**/*[sS]pec.ts'],
timeout: 6600000,
parallel: true,
jobs: 2,
require: ['tsconfig-paths/register', 'ts-node/register', './tests/mocha-test-hooks.ts'],
reporter: 'mocha-junit-reporter',
reporterOptions: {
mochaFile: './test-results/test-results.[hash].xml'
}
};

After running in debug I noticed, and maybe I'm wrong, but the mochaFile name is never changed.

mocha:runner reporterOptions: {
mocha:runner '[object Object]': true,
mocha:runner mochaFile: 'test-results.xml', <------------------
mocha:runner attachments: false,
mocha:runner antMode: false,
mocha:runner jenkinsMode: false,
mocha:runner properties: null,
mocha:runner toConsole: false,
mocha:runner rootSuiteTitle: 'Root Suite',
mocha:runner testsuitesTitle: 'Mocha Tests',
mocha:runner suiteTitleSeparatedBy: ' '

I tried updating my mocha config and changing the name to something random but the debugger always shows the mochaFile as 'test-results.xml'. I don't know that this is the issue but this is what I found.

I'm completely blocked. Has anyone figured this out?
