Introduction
In this tutorial we learn how to install libantlr3-gunit-java on Ubuntu 20.04.
What is libantlr3-gunit-java
libantlr3-gunit-java is:
gUnit is a “Unit Test” framework for ANTLR grammars. It provides a simple
way to write and run automated tests for ANTLR grammars in a manner similar
to Java unit testing framework jUnit. The basic idea is to create a bunch of
input/output pairs for rules in a grammar and gUnit will verify the expected
output/result. The input can be a single line or multiple lines of strings or
even an external file. The output can be simply success or failure, an
abstract syntax tree (AST), a rule return value, or some text output which
could be a rule’s template return value. The current version of gUnit has 2
main functions, interpreter and jUnit generator. The interpreter interprets
your gUnit script and runs unit tests using Java reflection to invoke methods
in your parser objects. The generator, on the other hand, translates your
gUnit script to jUnit Java code that you can compile and execute by hand.
