And yet this is one of the best methods knows to man (See double entry accounting which is used with great success in finance for hundreds of years). An interesting approach I’ve seen was - instead of writing tests - describing step by step scenario for fellow engineer to run on review. When it broke it was due to implicit assumptions or unclear instructions. I believe it was right solution as system input was triple digits of free form documents versus hundreds of configurations and rulesets. I couldn’t imagine dataset for those. Effect was more concise, stable test suite and a rather boring system.
