TypeError when using custom reporter

[gustawx]

Current behavior:

After running cypress with --reporter mochawesome I'm getting exception:

TypeError: Cannot read property 'passes' of undefined

Steps to reproduce: (app code and test code)

Set up according to documentation

Versions

"mocha": "^6.0.0",
"mochawesome": "^3.1.1",

"cypress": "^3.1.5"

• Can you provide the exact command you are running to run Cypress, including all arguments?

Also, I notice that mocha 6.0.0 just released 2 days ago. Can you try installing "mocha": "5.2.0" to see if that works? I'd like to narrow down whether this is an issue with their newest release.

[gustawx]

Thank you for quick answer. With mocha 5.2.0 it works fine, thank you.
I checked mocha-junit-reporter and the error is similar:

TypeError: Cannot read property 'failures' of undefined
...

[jennifer-shehane]

Yeah, I haven't thoroughly looked through Mocha 6's changelog to see if they've made a breaking change regarding this or if this is a bug on their part. Or maybe mochaawesome needs to update their code to handle Mocha 6. 😕

We use the mocha-junit-reporter with mocha-multi-reporters but not the mochawesome one, so this seems a problem in a BC break in mocha 6 itself. Will downgrade to 5.2 for the moment.

Hi,

I have 2 PR's tracking this upgrade to mocha 6, I use cypress & mochawesome for reporting.

They have circleci runs associated with them, in case anyone wants to track the change as the other dependancies update. I haven't had a chance to look into this yet in much detail

YOU54F/template-cypress-docker-typescript#15
https://github.com/YOU54F/cypressio-docker/pull/12

[YOU54F]

Just fixed this and proposed the following 2 PR's

stanleyhlng/mocha-multi-reporters#58
michaelleeallen/mocha-junit-reporter#80

My branch tracking the changes, with failing builds with mocha 6 pre and post fix is here

https://github.com/YOU54F/cypressio-docker-typescript/pull/15/files

If you do want to move up to mocha 6, you can pull my forked branch in the interim, whilst we wait for the maintainers of the source repo to review/merge/release the PR

    "mocha": "^6.0.0",
    "mocha-junit-reporter": "YOU54F/mocha-junit-reporter#master",
    "mocha-multi-reporters": "YOU54F/mocha-multi-reporters#master",
