Question

I need help with JUnit test. Test suite automation in JUnit.  

Answer 1

SOL:

JUnit basically tests the different modules of the entire source code in Java, commonly known as units. It is always better to first test individual units and then move to higher levels of development, than writing all the code and then testing the entire code. Hence JUnit is useful in this manner. And what it is doing in code, can be known only after having a look at the code.JUnit version can be determined, only after looking at the code.

he different annotations (@ statements in JUnit, along with their purpose:

@Before: used if some statement is to be executed before each test case

@After: used if some statement is to be executed after every test case

@BeforeClass: used if some statements are to be executed before all the test cases

@AfterClass: used if some statements are to be executed after all the test cases

@Ignores: used if some statements are supposed to be ignored during the execution of tests

The design of the JUnit code can be analyzed better after having a look at it.

Some important things to keep in mind:

1. Write all the test cases before writing the actual code, to form a basis for your implementation

2. Test cases that involve manual intervention of a user and that modify the data, should be avoided

3. Make sure that the names of the test cases are meaningful

4. Write one assertion per test method

5. Make maximum use of annotations(@ statements)

6. Make sure that the test codes are separated from the source code
