java - Running TestCases in JUnit on Ubuntu

Question

I am coming from Python world, so please forgive my ignorance. I am trying to learn TDD with JUnit framework in Java. I am following the method described by daniel kullmann in following thread: [How to install Junit][1].

The steps I am following are:

1. Writing Test Cases
2. Running command javac -cp /usr/share/java/junit4.jar Test.java
3. then java -cp /usr/share/java/junit4.jar:. org.junit.runner.JUnitCore Test

So far So good. But my question is:

1. Do I need to run both full line of command when I have to test my class ? I mean can't it be javac Test.java and java Test ? I have exported the path in .bashrc as below:

   export JUNIT_HOME=/usr/share/java

   export PATH=$JUNIT_HOME/junit4.jar:org.junit.runner.JUnitCore:${PATH}

2. I have downloaded latest junit framework 4-11 and kept at location /usr/local/JUNIT. But when I am running command java -cp /usr/local/JUNIT/junit-4.11.jar:. org.junit.runner.JUnitCore Test, its giving the error below:
