JUnit & DOS

When I tried coding this in VS Code, the plug-in did not recognize the system JDK so I reverted to DOS just because.

	javac -d bin src/boss/ScoreCollection.java
	javac -cp lib\junit-4.13.jar -d bin test/boss/ScoreCollectionTest.java
	javac -cp lib\junit-4.13.jar;bin -d bin test/boss/TestRunner.java
	java -cp bin;lib/junit-4.13.jar;lib/hamcrest-core-1.3.jar boss.TestRunner
	Result:
	test(boss.ScoreCollectionTest): Not yet implemented
	false
	For version 2:
	javac -cp bin;lib\junit-4.13.jar;lib\hamcrest-core-1.3.jar -d bin test/boss/ScoreCollectionTest.java
	java -cp bin;lib/junit-4.13.jar;lib/hamcrest-core-1.3.jar boss.TestRunner
