Multi-line strings not supported for assert_equals

Current behavior

Would it make sense to emit an error in case of multi-line strings telling the user that its not supported?

I wish that would be possible (or know how to do that...), however, at this point:

function assert_equals() {
  local expected="$1"
  local actual="$2"
  # ... etc ...

The issue is that there is no possibility to know if the second argumnet is a line that belong the text from the first argument or is a real new argument. Does it make sense? Therefore, for example, in here:

function assert_contains() {
  local expected="$1"
  local actual_arr=("${@:2}")
  local actual=$(printf '%s\n' "${actual_arr[@]}")

  if ! [[ $actual == *"$expected"* ]]; then
  # ... etc

what I am doing is to gather together all args (starting from the 2nd), store it into actual_arr and then concat all items with a new line \n into actual and so I can manipulate them easier. Does it makes sense and helps understand the intrinsic issue coming from bash? At least, I didn't find another way around to make this work so far... Maybe at a future time we find a better way to do this, but for now, I think it's good enough if this works in your PHPStan CI 😄

Expected behavior

Either allow the functionality to work OR notify the user that it's not supported

I wonder whether this problem is related to IFS:
