@troygibb this should be included in next week’s release. Thanks @halfninja for getting this into the reporter!

Can not express how annoying this is, especially for repos with tests that take long to run just to fail like this.

Happens both on 8.3 and 9.1 versions

My apologies… I totally missed it in the server package 😦 PR has been raised to fix it.

@halfninja This issue can be fixed if you turn on the debugging mode in Cypress. I was trying to report this as a bug to Cypress, but the issue is gone whenever I turn on the debugging mode.

Should be fixed in mocha-junit-reporter 2.1.0

We’ve seen this in 9.5.2 - it just happened once, with no code changes, and then passed after that. Feels like a bug in mocha-junit-reporter - in various places it assigns ._attr.time to a number or a string, so seems almost inevitable that sometimes it might try to call .toFixed on a string. Maybe worth raising this bug (or a PR) in that project to look at splitting those attrs into two or at least doing a typeof check.
