• A tip to create a separate test folder but with
  same java package
• TestCase should be in the same Java package so
  that it can test the program without "visibility"
  problems
• But we want to organize them so that we can see
  clearly that one is a test and one is the code

Using JUnit from EclipseSummary 1

• Using JUnit Wizard
• Goal ease the task of creating test case
• There's a wizard that helps you create a TestCase
  and TestSuite from some code you have created.
• Run JUnit from Eclipse
• Goal use integrated environment of Eclipse to
  run the test
• In Eclipse, we can code, test, run,
  debug!!

• Further Information
