Change subject: Extends QUnit.parameterize to take a callback providing the
test cases
......................................................................
Extends QUnit.parameterize to take a callback providing the test cases
By providing a callback, the parameters provided to the tests will be created
separately for each
test. This allows to provide instances which involve state without running into
problems when
manipulating state in one test case but expecting initial state in another one.
NOTE: We should probably make a fork of jQuery.parameterize and import its
tests, adjust them
to properly run in our environment. Also renaming things, like
"QUnit.cases" which should
perhaps better be "QUnit.provide".
This change set also changes some usage of QUnit.parameterize in our tests to
use a callback now.
