java - Unexpected method call while using PowerMock- EasyMock -

my problem seems misconception mocking. code test.

public class callhandler { private sqlsessionfactory sessionfactory; public callhandler() { string resource = "mybatis/mybatis-config.xml"; reader reader; seek { reader = resources.getresourceasreader(resource); sessionfactory = new sqlsessionfactorybuilder().build(reader); } grab (ioexception e) { e.printstacktrace(); } } public string handlerequest(call call) { // implementation } }

the test class

// have excluded few unnecessary classes @preparefortest post. @runwith(powermockrunner.class) @preparefortest({sqlsessionfactorybuilder.class, resources.class, sqlsessionfactory.class, sqlsession.class}) public class testcase0 extends testcase{ private sqlsessionfactory mockedsessionfactory = powermock.createmock(sqlsessionfactory.class); private sqlsession mockedsession = powermock.createmock(sqlsession.class); private callmapper mockedmapper = powermock.createmock(callmapper.class); private sqlsessionfactorybuilder mockedsqlsessionfactorybuilder= powermock.createmock(sqlsessionfactorybuilder.class); // others @before public void setup() { } @test public void test0 () throws exception { mockstatic(callmapper.class); mockstatic(sqlsessionfactorybuilder.class); mockstatic(resources.class); expect(resources.getresourceasreader("mybatis/mybatis-config.xml")).andreturn(mockedreader); expectnew(sqlsessionfactorybuilder.class).andreturn(mockedsqlsessionfactorybuilder); expect(mockedsqlsessionfactorybuilder.build(mockedreader)).andreturn(mockedsessionfactory); expect(mockedsessionfactory.opensession()).andreturn(mockedsession); // few more expectations replayall(); assertthat(result0).isequalto((new callhandler()).handlerequest(call)); verifyall(); } }

this mocking of phone call of build on new sqlsessionfactorybuilder not seem taking effect because of original build() beingness called , hence error. stack trace

without total illustration of code you're testing , test class itself, it's hard issues arising.

having said that, i'm guessing issue haven't prepared classes static methods. these need provided in @preparefortest annotation @ start of test class.

the documentation powermock provides next tips mocking static methods. i'm guessing you've missed out point 2. here source documentation

mocking static methods

quick summary

use @runwith(powermockrunner.class) annotation @ class-level of test case. use @preparefortest(classthatcontainsstaticmethod.class) annotation @ class-level of test case. use powermock.mockstatic(classthatcontainsstaticmethod.class) mock methods of class. use powermock.replay(classthatcontainsstaticmethod.class) alter class replay mode. use powermock.verify(classthatcontainsstaticmethod.class) alter class verify mode.

you mocking constructor phone call sqlsessionfactorybuilder you'll need consider tips too. here documentation this

mock construction of new objects

quick summary

use @runwith(powermockrunner.class) annotation @ class-level of test case. use @preparefortest(classthatcreatesthenewinstance.class) annotation @ class-level of test case. use powermock.createmock(newinstanceclass.class) create mock object of class should constructed (let's phone call mockobject). use powermock.expectnew(newinstanceclass.class).andreturn(mockobject) expect new construction of object of type newinstanceclass.class instead homecoming mock object. use powermock.replay(mockobject, newinstanceclass.class) alter mock object , class replay mode, alternatively utilize powermock.replayall() method. use powermock.verify(mockobject, newinstanceclass.class) alter mock object , class verify mode, alternatively utilize powermock.verifyall() method.

with tips in mind, produced next test method method provided trying test. test passes fine.
