the env system code is unecessarily fiddly. The current env system is the second env system, so the layer system will be the third implementation of the env system. the environment in which we run our tests is a layered environment like the scope in a programming language, but unlike with nested closures, tea permits the user to supply match tags to skip what would be stack frames in a system based on nested closures. It's more easily understood as being a system of layers, and that we skip non-matching layers. the env system also had the problem that it was a tree that was dynamically constructed as a side-effect of the execution tree, but each chain only needs to read its own ancestry in the environment tree. Having a single tree poses challenges for parellelizing the execution of different test chains, so instead, I would rather keep a list of layers for each chain, instead of keeping a single environment tree that is shared across all chains in the run. Additionally, the env system was sparse; tests that save no data put no nodes in the env tree. I would like to be able to display to users the layers available to their test in certain error cases so that they can understand why a match may have failed. Right now, in practice, encountering a match failure in a test plan is confusing to understand. |
