In Real casual japanese one may hear

> 明日のテストってこわ。。。

I am wondering, how often this level of 'casualness' happens.

Can I add sentence ending particles, even though there is an い omitted (and
です). For example:

> ゆきは走るのがはやね。

I omitted the whole structure, but still added ね to emphasize, that Yuki runs
fust, doesn't he?

However this is pretty standard, for a plain form, am I right?

> おもしろいね

If a similar question has been answered somewhere, please link it for me, and
also I'm not sure if my question is phrased correctly, I hope it's
understandable.

colloquial-language i-adjectives
Casual usage of i-adjectives and ending particles
There are several patterns for adjectives in casual speech:

One is that the end of the adjective changes to an "e" vowel, like おもしれー, はえー,
おせー, こえー, いてー.

One is that the end of the adjective changes to an "i" vowel, like
さみー,あちー,ねみー, かいー.

One is that the end of the adjective is omitted, like さむっ, あつっ, くさっ.

Some particles like な, よ, か can be added to them (except for in the omitted
ones), like おもしれーな, ねみーよ, さみーか but ね isn't usually added to them.

answer
ゆきは走るのがはやね is impossible.

Those stand alone stems of i-adjective are not so much a casual form as a kind
of interjection you use when you are surprised and it doesn't allow any
grammatical elements to follow. In addition, it's different from collapse of
diphthongs.
