Cannot set property message of ...Error which has only a getter

[mknj]

er.message is overwritten multiple times in the code.
This is incompatible with assertion libraries that make er.message readonly(getter, but no setter)

Please make "tap" compatible with "should" or update bdd example with compatible assertion library.

Example

var tap = require('tap')
let should = require('should')

tap.test('hello-world', (tap) => {
  x = -1
  x.should.equal(-2)
  tap.end()
})

Expected

    not ok 1 - AssertionError: expected -1 to be -2

Actual

    not ok 1 - Cannot set property message of AssertionError which has only a getter

Versions

• "should": "^13.2.1"
• "tap": "^11.1.3"
• node v8.10.0
