How do you generate dynamic (parameterized) unit tests in python?
... File "x.py", line 12, in test_sequence
self.assertEqual(a,b)
AssertionError: 'a' != 'b'
For historical reasons I'll leave the original answer circa 2008 ):
I use something like this:
import unittest
l = [["foo", "a", "a",], ["bar", "a", "b"], ["lee", "b", "b"]]
class TestSequense(unittest...
HTML-encoding lost when attribute read from input field
...1 I don't agree, if the function receives invalid input it should throw an error. If in a specific use case you want to handle invalid input in that way then either check the value before calling the function or wrap the function call in a try/catch.

What's the absurd function in Data.Void useful for?
... precisely right.
You could say that absurd is no more useful than const (error "Impossible"). However, it is type restricted, so that its only input can be something of type Void, a data type which is intentionally left uninhabited. This means that there is no actual value that you can pass to abs...
Why is require_once so bad to use?
... only included it once should suffice but if you're still getting redefine errors, you could something like this:
if (!defined('MyIncludeName')) {

}
I'll personally stick with the *_once statements but on silly million-pass benchmark,...

The compiler will object with bunch of variance check errors
In that case you may gather all type requirements in additional trait and parametrize other traits over it

In pure functional languages, is there an algorithm to get the inverse function?
... "chase" a solution while we explore a design space using "undefined" and "error" during development). A "bottom" x has the type a. It "inhabits" (or is a "value") of every type. This is a logical contradiction, since types are propositions and there is no value which satisfies every proposition....
