java.lang.IllegalStateException：没有对静态方法可用的模拟的最后一次调用

Question

im new to junit mocking. and im trying to mock below line.

IsomeInterface someinterface = someClass.getInstance();

where someClass is implementation of IsomeInterface . and getInstance is a static method which returns someClass object. below is the mocking i tried.

someClass someClassMock= PowerMock.createMock(someClass.class);
EasyMock.expect(someClass.getInstance()).andReturn(someClassMock);

exception:

java.lang.IllegalStateException: no last call on a mock available
    at org.easymock.EasyMock.getControlForLastCall(EasyMock.java:560)
    at org.easymock.EasyMock.expect(EasyMock.java:538)

Answer 1

Try

 PowerMock.mockStatic(ClassThatContainsStaticMethod.class)

to mock all methods of this class.

Also there can be a problem in constructing mock via powermock and verify them by easymock so try:

   PowerMock.expectNew(NewInstanceClass.class).andReturn(mockObject)
