Options

NameTypeDescription
methodPatternrequiredStringA method pattern is used to find matching method invocations. For example, to find all method invocations in the Guava library, use the pattern: com.google.common..*#*(..).

The pattern format is <PACKAGE>#<METHOD_NAME>(<ARGS>).

..* includes all subpackages of com.google.common.
*(..) matches any method name with any number of arguments.

For more specific queries, like Guava's ImmutableMap, use com.google.common.collect.ImmutableMap#*(..) to narrow down the results.
e.g. org.mockito.Matchers anyVararg()
newReturnTyperequiredStringThe fully qualified new return type of method invocation. Parameterized types like java.util.Set<java.lang.String> are supported; java.lang type arguments may use their simple name, e.g. java.util.List<String>.
e.g. long
