j2ts-junit

library92.0.0jsnpmunverified

Required runtime dependency for the J2TS transpiler that converts Java code to TypeScript. Version 92.0.0 is current. The package provides JUnit-like annotations and test infrastructure for transpiled TypeScript tests. Closely tied to the J2TS ecosystem; not useful standalone. Updated infrequently alongside the transpiler. No alternatives exist for J2TS projects.
