The test generation doesn't initialize the language (since it's already
initialized in main), but it still needs the warning enabled so it
matches the actual tests.
This changes the error message to be more clear on the output files and
also fixes an issue with the relative path of the offending file that
was not trimmed correctly.
The current code style guidelines forbid the use of `auto`.
Some uses of `auto` are still present, such as in UWP code (which
can't be currently tested) and macros (where removing `auto` isn't
easy).
This is meant for testing the GDScript implementation, not for testing
user scripts nor testing the engine using scripts.
Tests consists in a GDScript file and a .out file with the expected
output. The .out file format is: expected status (based on the enum
GDScriptTest::TestStatus) on the first line, followed by either an error
message or the resulting output. Warnings are added after the first
line, before the output (or compiler errors) if the parser pass without
any error.
The test script must have a function called `test()` which takes no
argument. Such function will be called by the test runner. The test
should not have any dependency unless it's part of the test too. Global
classes (using `class_name`) are registered before the runner starts, so
those should work if needed.
Use the command `godot --gdscript-generate-tests
godot-source/modules/gdscript/tests/scripts` to update the .out files
with the current output (make sure the output are the expected values
before committing).
The tests themselves are part of the doctest suite so those can be
executed with `godot --test`.
