Description
The test checks if typeof(params) is "string", but the message says "2nd argument to assert.throws has to be an array", and the usage of params as the 2nd argument to Function.apply confirms it should be an array or array-like object.
assert.throws = function(func, params, msg) { |
if (assert._debug && msg) print("in assert for: " + msg); |
if (params && typeof(params) == "string") { |
throw ("2nd argument to assert.throws has to be an array, not " + params); |
}
|
try { |
func.apply(null, params); |
}
|
catch (e) { |
return e; |
}
|
doassert("did not throw exception: " + msg); |
};
|
Similarly for assert.doesNotThrow.
Since func.apply will throw an exception if params is an unexpected type, this will make assert.throws always succeed in these cases.
> if (assert.throws(function(){throw("the exception")}, [])) print("success")

success

> assert.throws(function(){throw("the exception")}, [])
|
the exception

> if (assert.throws(function(){}, [])) print("success")

success // crap

TypeError: second argument to Function.prototype.apply must be an array
|
Likewise, assert.doesNotThrow will always fail (obviously less concerning, and there are only 56 uses of assert.doesNotThrow).
The error message should probably also use doassert rather than calling throw directly.
