Jmock unexpected invocation error

[smrititaneja18]

I am getting below error when i am trying to run Jmock unit test case:

unexpected invocation : connection.prepareStatement("SELECT * FROM table_name WHERE column1 = ? AND column2= ?")

`at org.jmock.internal.InvocationDispatcher.dispatch(InvocationDispatcher.java:85)
