4. Click Run.

How can protected methods be tested using JUnit?

To test a protected method using junit and mockito, in the test class (the class used to test the method), create a “child class” that extends the protagonist class and merely overrides the protagonist method to make it public so as to give access to the method to the test class, and then write tests against this child …

What is difference between assert and verify?

Assert: If the assert condition is true then the program control will execute the next test step but if the condition is false, the execution will stop and further test step will not be executed. whereas, Verify: There won’t be any halt in the test execution even though the verify condition is true or false.

What is the difference between assertEquals and assertSame?

assertEquals uses equals() method (that you should override in your class to really compare its instances) to compare objects, while assertSame uses == operator to compare them. So the difference is exactly the same as between == (compare by value) and equals (compare identity).

What is POM in Selenium Java?

Page Object Model, also known as POM, is a design pattern in Selenium that creates an object repository for storing all web elements. It is useful in reducing code duplication and improves test case maintenance.
