You will get array of Image from the resource as TypedArray
val imageArray = resources.obtainTypedArray(R.array.drawer_icons)

Is leaked memory freed up when the program exits?
... the OS keep track of all allocations? Any heap memory you allocate comes from the virtual memory space of the process - when the process terminates, that space is given back to the system wholesale, right? I don't see why the extra bookkeeping would be necessary, since the process making the allo...

What is the expected syntax for checking exception messages in MiniTest's assert_raises/must_raise?
...or
end
If you need to test something on the error object, you can get it from the assertion or expectation like so:
describe "testing the error object" do
it "as an assertion" do
err = assert_raises RuntimeError { bar.do_it }
assert_match /Foo/, err.message
end
it "as an exception"...
