69s left: [116, 101, 120, 116, 47, 104, 116, 109, 108] 69s right: [116, 101, 120, 116, 47, 104, 116, 109, 108, 59, 32, 99, 104, 97, 114, 115, 101, 116, 61, 85, 84, 70, 45, 56]
The formatting of the assertion failure message is less than ideal [116, 101, 120, 116, 47, 104, 116, 109, 108] is 'text/html' and [116, 101, 120, 116, 47, 104, 116, 109, 108, 59, 32, 99, 104, 97, 114, 115, 101, 116, 61, 85, 84, 70, 45, 56] is 'text/html; charset=UTF-8'
It looks like the immediate cause of this failure is that the behaviour of the web server at example.com changed. but build-time tests should not be trying to access stuff on the internet in the first place.
