Improve tests and testing framework including Github action(#35)

CatarinaGamboa · web-flow · commit 321ec216566f · 2024-11-29T13:56:39.000Z
Change test script to include all the tests in examples/testSuite including packages.
Paths in the testSuite are considered test cases if:
1. File that start with `Correct` or `Error` (e.g, "CorrectRecursion.java")
2. Package/Folder that contains the word `correct` or `error`.

Therefore, files/folders that do not pass this description are not verified.

Independent commits:
* make test fail to test github action

* change test file to verify filenames

* split steps of install and test

* include directories as elements to check - files inside directories have dependencies on one another

* change test car to car_correct

* rename test directories to have correct or error

* changed more package names

* change package name

* fix test file and test cases
