How to Improve Test Coverage to 80% with Generated Unit Tests and Stay Calm
summary
A generator creates React component scaffolding plus unit tests that fully cover all generated code; Jest snapshot tests and a sandbox exercise render branches. The workflow adds linters, pre-commit hooks and CI, while schema-driven mock generation and property testing produce varied inputs and proxies catch mutated constants. This approach yields about 80% test coverage overall, leaving roughly 20% (side effects, network handlers, event processors) for manual tests.
