Helper function for asynchronous testing

  • Repeats the given block (zero-arity function) until a timeout occurs or it returns a truthy value.
  • Catches ExUnit assertions and continues to try the block
  • Re-runs block one last time if it times out so assertions are run and throw helpful diffs, etc.
