make parameterized testing easier

[ayjayt]

I use parameterization in testing because it finds a lot of corner-case bugs.

Test results look like this:

I test many possible new configurations including extremes, etc, and then also test a range of configurations that shouldn't impact the new feature but might because of code proximity.

It does find bugs

In Jasmine and w/ ES5+Promises it's hard to implement manually because of all the weird scoping rules and promises and lack of ES6 tools like let. You can see my implementation here: https://github.com/plotly/plotly.js/blob/fe6f8d05828a789205448376c2d0f32ef71652a2/test/jasmine/tests/pikul_test.js#L28-L143

The messiness comes from scoping rules and reusing logic and etc. But it works well!

There is a module available on GitHub that has a much nicer interface: https://github.com/paucls/jasmine-parameterized but not sure about maintenance or other solutions.

Thoughts?

edit: also i'm back after a move, will get back around to this stuff mid/late next week- have to prepare a course
