TestNG Vs.Junit?
Advantages of TestNG
over Junit
·
In Junit we have to
declare @BeforeClass and @AfterClass which is a constraint where as in TestNG
there is no constraint like this.
·
Additional Levels of
setUp/tearDown level are available in TestNG like
@Before/AfterSuite,@Before/AfterTest and @Before/AfterGroup
·
No Need to extend any
class in TestNG.
·
There is no method
name constraint in TestNG as in Junit. You can give any name to the test
methods in TestNG
·
In TestNG we can tell
the test that one method is dependent on another method where as in Junit this
is not possible. In Junit each test is independent of another test.
·
Grouping of testcases
is available in TestNG where as the same is not available in Junit.
·
Execution can be done
based on Groups. For ex. If you have defined many cases and segregated them by
defining 2 groups as Sanity and Regression. Then if you only want to execute
the “Sanity” cases then just tell TestNG to execute the “Sanity” and TestNG
will automatically execute the cases belonging to the “Sanity” group.
·
Also using TestNG your
selenium test case execution can be done in parallel.
How we can tell that one test is dependent on another in testng?
