SpecBinder

Gherkin specs are translated to Java during the build, so javac checks the binding. Missing steps, wrong parameter types, invalid enum values, broken data table columns — caught before any test runs.

No Cucumber runner, no step discovery, no parallel toolchain. Generated scenarios are ordinary @Test methods that your IDE, build, and CI run, debug, and report on like any other JUnit test.

No global step registry, no runtime lookup, no ambiguous matches. Each feature gets its own generated test class, so steps belong to the feature that uses them — shared deliberately through Java inheritance when that actually helps.

No ScenarioContext, no string-keyed maps, no DI container for moving values between steps. State lives in ordinary fields on the test class, reset for each scenario by JUnit's default lifecycle.

No string-keyed row maps, no manual cell parsing, no late surprises from renamed columns. Each table row becomes a typed parameter object — column drift, type mismatches, and invalid enum values surface at compile time.

Red-green-refactor works at every level of detail. A rule with no scenarios fails. A scenario with no steps fails. A scenario with steps fails until they're implemented. The TDD loop pulls you top-down to the next missing piece.
