antlr-ng Unit Tests ​

Introduction ​

Unlike in ANLTR4 there's only one set of unit tests in antlr-ng: those for the tool itself. The original tool unit tests from ANTLR4 were translated to TypeScript and are running now as action on Github. To execute them locally, follow the same step as laid out in the Getting Started and the Building Section. Download the repository (via git), install dependencies using npm i and then run the tests using

bash
npm run test

which will give you:

zsh
> antlr-ng@1.0.4 test
> vitest --no-watch --no-coverage

All tool unit tests are located in the tests/ folder. There are no runtime tests in the repository, since they are now the responsibility of the runtime projects.
