I'm searching for a word (singular or plural) to refer to a time of testing. A time when a person (or organization/civilization) is put to the test and, if they pass, they will come out of it changed for the better and stronger than ever.
- They were testing times for the greek, but they became even stronger and more resolute after their _____________.
- I have my finals next week. You could say it's gonna be my ___________.
- Next month, the company is under a goverment inspection. It's gonna be a ___________ to them.
The words provided don't need to fit perfectly in those examples; minor variations/rephrasing is allowed
