Static Method. A method in Java is static when it is preceded by the keyword “static”. Some points that you need to remember about the static method include: A static method belongs to the class as against other non-static methods that are invoked using the instance of a class.

Observation : When you call static method within a static entity, you need to change the class in @PrepareForTest. For e.g. : securityAlgo = MessageDigest.getInstance(SECURITY_ALGORITHM); For the above code if you need to mock MessageDigest class, use @PrepareForTest(MessageDigest.class) While if you have something like below :
The static keyword can be used in several different ways in Java and in almost all cases it is a modifier which means the thing it is modifying is usable without an enclosing object instance.

Oct 16, 2018 · We can mock a static method by JMockit. JMockit is used for mocking the external dependencies outside the test boundary, similar to Mockito and other such mocking libraries. The most important feature of JMockit is that it lets us mock anything, even the things that are hard to mock with other libraries such as constructors, static and final methods.
What the compiler is complaining about is that it cannot simply insert the standard "this." as it does within instance methods, because this code is within a static method; however, maybe the author merely forgot to supply the instance of interest for this invocation — say, an instance possibly supplied to the static method as parameter, or created within this static method.
