[tests][monotouch] Generalize some tests to be independent of iOS version. Fixes #51801

[spouliot]

The exact values are not what we need to test for and varies with
different OS versions - making tests fails for no good reason (i.e.
they are not canary used to detect changes)

@spouliot Canary used? Can you explain? I don't see how it applies here, in the context of the monotouch-tests.

Here's the definition of "canary testing" I found:

In software testing, a canary is a push of programming code changes to a small group of end users who are unaware that they are receiving new code. Because the canary is only distributed to a small number of users, its impact is relatively small and changes can be reversed quickly should the new code prove to be buggy.

For the curious who, like me, didn't know where "canary testing" came from:

The word canary was selected to describe the code push to a subset of users because canaries were once used in coal mining to alert miners when toxic gases reached dangerous levels.

@VincentDondain

Canary Tests are minimal tests to quickly and automatically verify that the everything you depend on is ready. You run Canary tests before other time-consuming tests, and before wasting time investigating in your code when the other tests are red. If the canary test fails, you know you have to fix something on the environments first.

In this case the value we checked was not a canary and had no real value (beyond confirming the call worked).

note: your definition match the "canary deployment" (not test)

monotouch-test crashes are tracked in https://bugzilla.xamarin.com/show_bug.cgi?id=52162 but hides the result of the current PR :(

@spouliot ah yes makes sense, I guess mine was "canary deployment".

Too many canaries! 🦆
