🔧 Bug Fixes & Patches (6)
- When `visible` assertions such as `should('be.visible')` fail we now print the reason Cypress thought the element was invisible. Matches what Cypress prints out when attempting to interact with invisible elements. Fixes #221.
- Prevent `Host` header from having its port appended when request was for port `80` or `443` which lead to 3rd party reverse proxy problems such as with `zeit.co` hosting. Fixes #222.
- Send valid http response errors, and display new lines correctly. Fixes #218.
- Correctly inject on `5xx` http response codes. Fixes #217.
- Correctly inject on `4xx` and other bad http response codes when using Cypress as the file server. Fixes #219.
- Correctly inject on `gzip` errors from 3rd party servers doing dumb things. Fixes #220.
