kandi X-RAY | short-unique-id Summary
This largely depends on the given dictionary and the selected UUID length. Out of the box this library provides a shuffled dictionary of digits from 0 to 9, as well as the alphabet from a to z both in UPPER and lower case, with a default UUID length of 6. That gives you a total of 56,800,235,584 possible UUIDs. So, given the previous values, the probability of generating a duplicate in 1,000,000 rounds is ~0.00000002, or about 1 in 50,000,000. If you change the dictionary and/or the UUID length then we have provided the function collisionProbability() function to calculate the probability of hitting a duplicate in a given number of rounds (a collision) and the function uniqueness() which provides a score (from 0 to 1) to rate the "quality" of the combination of given dictionary and UUID length (the closer to 1, higher the uniqueness and thus better the quality). To find out more about the math behind these functions please refer to the API Reference.

QUESTION
I've been trying for a couple of days now to get some tests to run.
I've two environments, one very "empty" and another with a full project. The 'empty' one does run a very simple test (but doesn't contain the Person object that is unable to be constructed in the full project).
I migrated the full project to a very similar environment in terms of installed dev packages, karma, jasmine versions and such. I also copied the tsconfig.json, karma.conf files across. Those are below.
For the life of me I cannot figure out why the karma tests will not run. With previous versions of Karma I would get an error along the lines of 'scheduler_person.b' is not a constructor.
Digging a little deeper, it's failing on this line of test.store.ts:

you need to move all of your global constants (and subsequent method calls) into the SetupStore
method of the NPBCStoreConstruction
class. When I do this I can run the test suite properly.
The cause of issue is that when Webpack/Typescript/something compiles everything, it picks an arbitrary order to include all the files and if you look at the generated code you can see that the global invocation of the person Person
constructor happens before it is defined.
