.toImplement does not properly check type

[mrozbarry]

The example for .toImplement() uses a hash where the key must exist, and implies that the value is the type the actual value should be. This method does not seem to test for individual types off the actual object, and fails when we build a mock object that is exactly what the test expects, ie:

This will pass:

expect({
  foo: 'bar',
  baz: 123,
  foobarbaz: [1, 2, 3]
}).toImplement({
  foo: String,
  baz: Number,
  foobarbaz: Array
})

but so will this:

expect({
  foo: 'bar',
  baz: '123',
  foobarbaz: [1, 2, 3]
}).toImplement({
  foo: String,
  baz: Number,
  foobarbaz: Array
})

Even though baz is a string but is expected to be a number.

If this is just checking for the existance of all attributes, why not have toImplement accept an array of the hash keys?

Yes absolutely, I need to finish this so it uses the types.

Thanks a lot.
