Goal: Instant evaluation, never lose work.
Story 13.5: Test Suite
As a CalcPad developer, I want a comprehensive test suite with > 95% code coverage on calcpad-engine, So that regressions are caught early and every function, conversion, and multi-line interaction is verified.
Acceptance Criteria:
Given the calcpad-engine crate
When the full test suite is executed via cargo test
Then code coverage as measured by cargo-tarpaulin or equivalent exceeds 95% of lines in the engine crate
And all tests pass with zero failures
Given every public function and unit conversion in calcpad-engine When unit tests are written Then each function has at least one test for the happy path And each function has at least one test for error/edge cases (division by zero, overflow, unknown unit, etc.) And every supported unit conversion pair has a dedicated round-trip accuracy test
Given multi-line sheets with variables, dependencies, and mixed expressions When integration tests are executed Then end-to-end evaluation of representative sheets produces correct results And integration tests cover: variable assignment and reference, chained dependencies, circular reference detection, unit conversion across lines, and currency conversion
Given the engine's parsing and evaluation logic
When property-based tests are run via proptest
Then random valid expressions always produce a result without panicking
And random malformed expressions produce a graceful error without panicking
And evaluation of a + b always equals evaluation of b + a for numeric values
Given the benchmark suite defined with criterion
When benchmarks are executed
Then benchmarks exist for: single-line evaluation, 100-line sheet evaluation, 500-line sheet evaluation, DAG rebuild, and unit conversion lookup
And benchmark results are recorded so regressions can be detected in CI
