loading tested module only once in setup

[michal-lipski]

When I have some not idempotent operations in module config I don't want to run it every time I run test:

angular.module('numerals', []) .config(() => { numeral.register('locale', 'pl',{...} // cannot register multiple times })
This config code is executed each time when I run test for this module:
app.runHtml('....')

It would be nice to do it only when we create testing app:
app = test.app([numbers]);
