What are the Junit Testing advantages?
Due to simple nature the Junit, it will be the first option when testing with java application. It is separately integrated with Ant and Maven tools and other tools like Dbunit database testing unit, XML testing which simplifies XML testing.
During the process of Junit testing applications, the developers may face many problems like, the flow of applications cannot be tested only by main method. For example, if we want a web application, if we want to test the flow we need to deploy it on the server and change the java code. The testing time will increase. The user will be not sure if this kind of test is passed or not. Junit can solve all these issues of testing as, it is only used to test the actual class. Using Junit can save time. Using system.out.println will output the message which will not assure that the result will be collected in structured way.
Junit test cases can be implemented in DAO classes. Junit can be employed to test the series of program code singularly or multiple units.java testing is the first which developed the idea of testing and coding which assured the setting up of data defining the expected output. Junit can identify the bugs, sometimes the bugs can be introduced when new features are added or when the existing code is changed. This shows the regression. The Junit provides the text based command lines and AWT and swing based graphical test reporting. Junit is widely accepted by organization around the world for performing unit test in java programming. Junit programming test became the standard for testing in java programming language. The annotations of JUnit testing, that can be used while writing the test cases in Junit framework are
@Test: the test annotation specifies the test method.
@Test(timeout=1000) this type of annotations specifies that the method will be failed if it takes more than 1000 milliseconds.
@BeforeClass: this annotation specifies that the method will be invoked only once before all tests starts.
Before: this method invokes at the very beginning of the each test.
@After: this annotation invokes this method invokes after each test.
@After class annotation specifies that the method will invoke only once at the end of all test.
The org.Junit package contains many interfaces and classes like Assert, Test, before
After for Junit testing.
