-## E2E Tests:
-
-- Testdatei mit Main ausführen/kompilieren
-- Testdatei mit "javac -d output .\CompilerInput.java" kompilieren
-- -> Dateien mit javap vergleichen
-
-wenn beides erfolgreich
-
-- Ergebnis vom eigenen Compiler mithilfe von main.EndToEndTester ausführen
-- (Ergebnis von javac mithilfe von main.EndToEndTester ausführen)
-
-### Andis Tipps:
-
-- cp mitgeben
-- makefile
-- java -jar pfadtocompiler.jar EmptyClass.java
-- mvn package
-- javac tester // tester compilen
-- java tester // tester ausführen
-- -> tester ist in unserem Fall main.EndToEndTester.java
-- -> Hab ich alles umgesetzt
