With Mockito, how to stub a method with return type void which throws an exception when a certain argument is passed?
On a first glance, the answer is simply: well, there are several mocking frameworks out there, and there are different ways to use them.
The first example tells JUnit to use the "unit test runner" that the Mockito mocking framework provides. The second example uses the unit test runner from the PowerMock framework.
In order for things to make sense, you would also have different import statements, as both frameworks have different implementations for the @Mock annotation for example.
( the main point of using these framework-specific test runners is that they take care of initializing all the fields with special framework-specific annotations ).
So: the difference here is simply that: the first example is written to use the Mockito framework, the second one uses PowerMock.
Now, which one of those to use?
Answer: Mockito.
Why? Somehow an ugly truth is: the PowerMock-one basically is a cry for help. It says "the class under test is badly designed, please fix it". Meaning: as a developer, you can write "easy to test" code, or "hard to test" code. Many people do the second: they write code that is hard to test. And then, PowerMock(ito) provides means to still test that code.
PowerMock(ito) gives you the ability to mock (thus control) calls to static methods, and to new()
. To enable that, PowerMock(ito) manipulates the byte code of your code under test. That is perfectly fine for small code bases, but when you face millions of lines of production code, and thousands of unit tests, things are totally different.
I have seen many PowerMock tests fail for no apparent reason, to find out hours later ... that some "static" thing somewhere else was changed, and that somehow affect a different PowerMock static/new driven test case.
At some point, our team made a conscious decision: when you write new code, and you can only test that with PowerMock ... that isn't acceptable. Since then, we only created Mockito test cases, and not once since then we saw similar bizarre problems that bugged us with PowerMock.
The only acceptable reason to use PowerMock is when you want to test existing (maybe 3rd party) code that you do not want to modify. But of course, what is the point of testing such code? When you can't modify that code, why should tests fail all of a sudden?

These days, development teams depend heavily on feedback from automated tests to evaluate the quality of the system they are working on.
Nowadays, automation is becoming integral to the overall quality of the products being developed. Especially for mobile applications, it’s even more important to implement automation robustly.
The rapid shift in the use of technology has impacted testing and quality assurance significantly, especially around the cloud adoption of agile development methodologies. With this, the increasing importance of quality and automation testing has risen enough to deliver quality work.
I was once asked at a testing summit, “How do you manage a QA team using scrum?” After some consideration, I realized it would make a good article, so here I am. Understand that the idea behind developing software in a scrum environment is for development teams to self-organize.
In addition to the four values, the Agile Manifesto contains twelve principles that are used as guides for all methodologies included under the Agile movement, such as XP, Scrum, and Kanban.
