+# Terminal emulators all present a pretty similar interface.
+# That gives us an opportunity to easily test their basic functionality with a single codebase.
+#
+# There are two tests run on each terminal emulator
+# - can it successfully execute a command passed on the cmdline?
+# - can it successfully display a colour?
+# the latter is used as a proxy for "can it display text?", without going through all the intricacies of OCR.
+#
+# 256-colour terminal mode is used to display the test colour, since it has a universally-applicable palette (unlike 8- and 16- colour, where the colours are implementation-defined), and it is widely supported (unlike 24-bit colour).
+#
+# Future work:
+# - Wayland support (both for testing the existing terminals, and for testing wayland-only terminals like foot and havoc)
+# - Test keyboard input? (skipped for now, to eliminate the possibility of race conditions and focus issues)
