Rebuilding Espec: Foundations In Metaprogramming,
summary
Rebuilds a small portion of ESpec by implementing concrete metaprogramming pieces: macros that define describe/context/it style DSL, using quote/unquote AST manipulation to inject code at compile time, and a before_compile hook plus Module.register_attribute(..., accumulate: true) to collect tests. Dynamically generated test functions run via a simple mix task test runner; assertions implement an assert/match/success/error interface and the demo repo proves the approach compiles, runs, and prints per-test success output.
