[michaelw85]

Expected behavior

No errors

Actual behavior

Errors when 2nd test suite is run. "Cannot read property xxxx of undefined"

Information about the Issue

Using following packages:

    "cypress": "^3.1.5",
    "mocha": "^6.0.0",
    "mocha-junit-reporter": "^1.18.0",
    "mocha-multi-reporters": "^1.1.7",

Steps to reproduce the behavior

Follow this guide to setup mocha-multi-reporters in cypress and run a test setup with 2 separate test files using spec and junit reporter.

Workaround

Downgrade to mocha 5.2.0 and everything is working as expected.

Just fixed this and proposed the following 2 PR's

#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",
