Game Tests backport for 1.12.2

This framework is in the alpha stage. There are a lot of missing features compared to the 1.17+ Game Tests.

How to use

Add this mod to dependencies:

dependencies {
    implementation("com.bqc0n:mctest:0.0.2")
}

and write some tests:

@GameTestHolder("mctest")
public class Tests {
    @GameTest
    public void placeDirt(GameTestHelper helper) {
        BlockPos pos = BlockPos.ORIGIN.up();
        helper.setBlock(pos, Blocks.DIRT);
        helper.succeedWhenBlockPresent(Blocks.DIRT.getDefaultState(), pos);
    }
}

Note that the GameTestHolder annotation is required.

then run the tests using the mctest runall command:

Test names and structure names

Test name will be <namespace>:<class name>.<method name> in lowercase, so in the example above it will be mctest:tests.placedirt.

Structure name is a bit more complicated, it will be

1. <namespace>:<class name>_<method name> if no template specified in @GameTest annotation.
2. <namespace>:<class name>_<template> if template is specified in @GameTest annotation, but no : in it.
3. <template> if template is specified in @GameTest annotation and it contains :.

All above is in lowercase. So in the example above it will be mctest:tests_placedirt. Underscores are used instead of dots because we can't use dots in 1.12.2 structure names.
