JUnit Test 'assertSame' Example Using Ant

                         

This example illustrates about how to use the 'assertSame' assertion method. The method is used to compare between two variable whether both are same or not, if both expected and actual are not same then the AssertionError Exception throw the following error:

[junit] Testsuite: AssertSameExample
[junit] Tests run: 1, Failures: 1, Errors: 0, Time elapsed: 0.031 sec
[junit]
[junit] Testcase: test(AssertSameExample): FAILED
[junit] not equal expected same:<2> was not:<4>
[junit] junit.framework.AssertionFailedError: not equal expected same:<2> was not:<4>
[junit] at AssertSameExample.test(Unknown Source)
[junit]
[junit]
[junit] Test AssertSameExample FAILED

but if both are same then the program executed test case successfully. In this example build.xml file is used to compile, test and run the java file. The <property name="TALK" value ="true"/> is used to search path for source files, search path for class files, parsing the jar file, loading the all required classes and checking the class file. If  <property name="TALK" value ="true"/> is not used in build.xml file then the output displays only  [junit] Testsuite
