When comparing objects with certain length properties, the reporter throws when stringifying the diff. Reduced repro:
it('compare two objects', function () {
assert.deepEqual({length: {toString: 0}}, {length: 1});
});Expected:
AssertionError: { length: { toString: 0 } } deepEqual { length: 1 }
+ expected
- actual
{
- "length": {
- "toString": 0
- }
+ "length": 1
}Actual:
TypeError: Cannot convert object to primitive value
