"mocha-trx-reporter" throwing error as "TypeError: Cannot read property 'start' of undefined""

[gadepallavi]

I am trying to use "mocha-trx-reporter" to generate the ".trx" file for my E2E tests. I installed the "mocha-trx-reporter" latest version which is "^3.2.3". After installing when I tried to run the tests it is showing error as "TypeError: Cannot read property 'start' of undefined" in file "\node_modules\mocha-trx-reporter\lib\trx.js" line 83

Hi @gadepallavi your error points to a missing "stats" property but I can't find the root cause for that. Could you describe your setup?
node, npm and mocha versions?

Hello, please find the requested infomration below:

Versions:
node: v12.16.1
npm: 6.14.3
mocha: ^5.2.0

Describe the steps:

1. Installed the mocha-trx-reporter version (^3.2.3)
2. Updated the script to use the mocha-trx-reporter as display below:
   "npm run build && mocha --reporter mocha-trx-reporter --reporter-options output=./TestResults/test-result.trx Output/**/*.test.js"
3. After adding above statement, when I run my E2E tests it, chrome broweser launch and it executes the tests, however at the end of the test gives me mentioned error as "TypeError: Cannot read property 'start' of undefined" in file "\node_modules\mocha-trx-reporter\lib\trx.js" line 83" and I dont see the ".trx" file generated for it.

Please let me know if you need any details.

Regards,
Pallavi

Thanks for the info. I think that the problem is a mismatch between the mocha version included in mocha-trx-reporter and your project's mocha version.

Now I changed mocha dependency to be a peer-dependency, which I think it's the correct approach. With this change the reporter will work with your mocha version instead of bundling its own.

It's not yet published to npm, you can try the fix by installing it from github:

npm install "github:Infragistics/mocha-trx-reporter#23b98b433ad11dd70b05ef265f4d989afa95637a"

Please let me know if this works for you.

The fixed version has been published to npm, you can now install it as standard dep:
npm install --save-dev mocha-trx-reporter@3.2.4
