NullPointerException in Mockito when mocking method with primitive argument
any()
returns null
. This choice was inevitable because the signature of any()
is
public static <T> T any()
Since generic types are erased in Java, and since nothing is passed to the method that carries any type information (such as a Class<T>
), null
is the only reasonable return value.
This creates a problem if the method of the mock has an argument of primitive type because unboxing this null
value throws a NullPointerException
.
There are two possible solutions. You can either use the primitive versions (such as anyDouble()
), or the version accepting a Class
(e.g. any(Double.class)
). In the latter case, since we are supplying type information to the method, it is possible to use this information to return a sensible non-null value (e.g. 0.0D
in the case of double).

Anyone who has worked in the software industry for a while can tell you stories about projects that were on the verge of failure. Many initiatives fail even before they reach clients, which is especially disheartening when the failure is fully avoidable.
Software Risk Management (SRM) combines a set of tools, processes, and methods for managing risks in the software development lifecycle. In SRM, we want to make informed decisions about what can go wrong at various levels within a company (e.g., business, project, and software related).
In today’s fast-paced world, the primary goal of every business is to release their application or websites to the end users as early as possible. As a result, businesses constantly search for ways to test, measure, and improve their products. With the increase in competition, faster time to market (TTM) has become vital for any business to survive in today’s market. However, one of the possible challenges many business teams face is the release cycle time, which usually gets extended for several reasons.
