Testing Interface methods using Mockito

I am writing a JUnit test case for a method which internally invokes another method through interface. I am using Mockito to mock the interface but for some reason it gives me NPE. I debugged through but wasn't able to get any clue to fix it. getAllVendors() method throws exception which comes through an Interface.
MUT
public void prepare() throws AccountServiceException, ManagerException {
vendors = getVendorManager().getAllVendors();
microsites = new ArrayList<VendorMicrositeTO>();
microsites.add( new VendorMicrositeTO( "http://www.docusign.com", "docuSign" ) );
clientUser = createClientUserObject();
}
JUnit
#Test
public void testPrepare() throws Exception {
AccountAction accountAction = new AccountAction();
Map<String, Object> actionMap = new HashMap<>();
actionMap.put("application", "ESignatureIntegrationAction");
ActionContext.setContext(new ActionContext(actionMap));
String beanName = Constants.VENDOR_MANAGER_SPRING_BEAN;
PowerMockito.mockStatic(AppContext.class);
PowerMockito.when(AppContext.containsBean( beanName )).thenReturn( true );
IVendorDto iVendorDto = new VendorDto();
iVendorDto.setActive(true);
iVendorDto.setCreatedBy("9/15/2016");
iVendorDto.setName("CorpESignClientUser");
iVendorDto.setCreatedBy("SYSTEM");
List<IVendorDto> vendorList = new ArrayList<>();
vendorList.add(iVendorDto);
IVendorManager iManager = Mockito.mock((IVendorManager.class));
Mockito.when(iManager.getAllVendors()).thenReturn(vendorList);
accountAction.setVendors(vendorList);
accountAction.prepare();
}

Thanks, in advance

Seems you forgot to add a line in your test like:
accountAction.setVendorManager(iManager);

So yeah, I have been tackling a very similar issue.
This usecase is a logical outcome of the application of the SOLID principles within an IoT based application. If you decouple the layers of your application using interfaces and are testing an innner layer you are bound to come across testing an interface whose implementations have more interface dependencies.
You can achieve this goal using two testing angles combined
Use the Parameterized JUnit runner to launch the one set of unit tests for all of the implementations.
Then internally during each run initialize the mocked dependencies using Mockito
For more information on Parameterized testing (that's where i originally found it) be sure to visit this post. The manual initialization of mockito was something i found here.
All and all the resulting code looks like this:
#RunWith(Parameterized.class)
public class YourInterfaceTest {
#Mock
private ImplementationDependency sneakyBreakyNpeAvoided;
#InjectMocks
private YourInterfaceToTest iface;
// constructor is used by the Parameterized runner to provide impelementations
public YourInterfaceTest (YourInterfaceToTest ifaceToTest) {
this.iface = ifaceToTest;
}
// this method is called always before running tests so a good time to inject anything
#Before
public void init() {
MockitoAnnotations.initMocks(this);
Mockito.when(sneakyBreakyNpeAvoided.returnTrue()).thenReturn(true);
}
#Test(expected = IllegalArgumentException.class)
public void doSomething_nullParameter_throwsIllegalArgumentException() {
Assert.fail(); // tests here :)
}
#Parameterized.Parameters
public static Collection<YourInterfaceToTest > provideImplementations() {
// change to Arrays.asList when multiple implementations are available
return Collections.singletonList(new YourInterfaceImpl());
}
}
Hope I understood the OP's issue well.

Powermock unable to mock MysqlConnect

The is my Mysql Class:
public class MysqlConnection {
public Connection MysqlConnect() {
String url = "jdbc:mysql://localhost:3306/";
String dbName = "dashboard";
String driver = "com.mysql.jdbc.Driver";
String userName = "root";
String passwd = "";
Connection conn = null;
try {
Class.forName(driver);
conn = DriverManager.getConnection(url+dbName,userName,passwd);
} catch (Exception e) {
e.printStackTrace();
}
return conn;
}
}
And my PowerMockito test class is like this:
#RunWith(PowerMockRunner.class)
#PowerMockIgnore("javax.management.*")
#PrepareForTest(Class.class)
public class MysqlConnectionTest {
#Test(expected = ClassNotFoundException.class)
public void MysqlConnectiontest() {
PowerMockito.mockStatic(Class.class);
try {
when(Class.forName(Mockito.anyString())).thenThrow(new ClassNotFoundException("error message"));
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
obj.MysqlConnect();
}
}
The Stacktrace of the error is:

The program is not mocking any line of code but is executing the code from the actual MySQLConnect function instead. It is making use of the actual driver. If I remove the expected part from #Test the test succeeds. That is, no mocking is done, driver is loaded and everything.

You cannot mock java.lang.Class with PowerMockito or any other mocking framework which relies on runtime byte code modification.
Reason for this is that those classes are already loaded when the mockito agent is manipulating (instrumenting) the classes that should be mocked.
Why don't you instead mock your MysqlConnection class? There you could spy on your MysqlConnect method and return a mocked connection instead.

PowerMock - NPE on #PrepareForTest

Problem: The instrumentation class in PowerMock isn't being initialized. I'm loading the library through the #Rule annotation. I've got the VM argument in place:
-javaagent:project_path/libs/powermock-module-javaagent-1.5.jar
When I walk through with the debugger, PowerMockAgent#premain gets called and the instrumentation object gets set, but when it's called during the test setup, the instrumentation object is null, throwing the error below.
Why is the instrumentation variable not keeping it's value between when PowerMockAgent#premain is called and when PowerMockClassRedefiner.redefine calls it?
Instrumentation gets set correctly here on load:
private static void initialize(String agentArgs, Instrumentation inst) throws IOException {
instrumentation = inst;
inst.addTransformer(new DefinalizingClassTransformer(), false);
inst.addTransformer(classTransformer, true);
}
But when called again from #PrepareForTest({ Logger.class }), is null
public class PowerMockClassRedefiner {
public static void redefine(Class<?> cls) {
if(cls == null) {
throw new IllegalArgumentException("Class to redefine cannot be null");
}
PowerMockAgent.getClasstransformer().setClassesToTransform(Arrays.asList(cls.getName()));
try {
PowerMockAgent.instrumentation().retransformClasses(cls);
} catch(Exception e){
throw new RuntimeException("Failed to redefine class "+cls.getName(), e);
}
}
Resulting in error:

Here's my test setup:
#RunWith(RobolectricTestRunner.class)
#PrepareForTest({ Logger.class }) // THIS IS WHERE THE ERROR GETS THROWN
public class LoggerTest {
#Rule public PowerMockOverriderRule rule = new PowerMockOverriderRule();
public LoggerConfig config;
#Before
public void setUp() {
config = mock(LoggerConfig.class);
}
UPDATE:
Removing the #RunWith(RobolectricTestRunner.class) fixes the problem, but isn't an option for my project. (It's an Android project).

I'm sorry to ask but why would you even want to mock a Logger class? If you want to ensure that the output is logged to the console you can wrap a logger in an abstraction that you can mock.
class LogWraper {
void someMethod() {
logger.log()
}
}
and then you can create a mock of your FooWraper. No need to use Powermock at all...

PowerMock - Mocking static system class throws IllegalStateException

I have the following code
public class A{
public void createFile() {
File tempXmlFile = null;
String extension = ".xml";
String name = "someName";
try {
tempXmlFile = File.createTempFile(name, extension);
if (tempXmlFile.exists()) {
tempXmlFile.delete();
}
} catch (IOException e) {
System.out.println(e.getStackTrace());
}
}
}
#RunWith(PowerMockRunner.class)
#PrepareForTest(A.class)
public class testA extends TestCase{
private A classUnderTest;
#Override
#Before
public void setUp() {
classUnderTest = PowerMock.createMock(A.class); //the class is more complex in my case and I have to mock it
}
public void testCreateFile() throws IOException{
String extension = ".xml";
String name = "someName";
PowerMock.mockStatic(File.class);
File tempFileMock = PowerMock.createMock(File.class);
expect(File.createTempFile(name, extension)).andReturn(tempFileMock);
expect(tempFileMock.exists()).andReturn(true);
expect(tempFileMock.delete()).andReturn(true);
replay(File.class, tempFileMock, classUnderTest);
classUnderTest.createFile();
verify(File.class, tempFileMock, classUnderTest);
}
}
In the test class as I said the class under test must be mocked(I can't create a new object).
When I run the test I get:

I read the documentation here http://code.google.com/p/powermock/wiki/MockSystem but the test stil wont't work. Am I missing something?
Edit: I tested the previous code with a real A object (and removed it from replay)
classUnderTest = new A();
but I still get the same exception.

Try adding File.class to #PrepareForTest.

try the org.powermock.reflect.internal.WhiteboxImpl.newInstance() method to create the object of the class and then call method directly.
1) this will suppress the constructor of the class
2) if your class contains static block then use suppressStaticInitilaizationFor to suppress that.
regards
Anil Sharma

Add File.class to #PrepareForTest and check the imports of replay and verify. They should be from PowerMock.

I think you need to suppress constructor
Check this

I am using OpenEJB4 for JUnit testing.
The EJB itself is stateless with no transaction annotation (which makes the Transaction required). I found an older post on this forum and tried the same fix but didnt work. I dont have hibernate validation on my classpath. Am using Hibernate 3.
My test is as follows,
public class ProviderManagerTest extends TestCase {
Context context;
/**

p.put(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.core.LocalInitialContextFactory");
p.put("log4j.category.OpenEJB.options ", " debug");
p.put("RcsDB", "new://Resource?type=DataSource");
p.put("RcsDB.JdbcDriver", "oracle.jdbc.driver.OracleDriver");
p.put("RcsDB.JdbcUrl", "jdbc:oracle:thin:#dbserver:1521:ttv");
p.put("RcsDB.JtaManaged", "true");
p.put("RcsDB.JtaManaged", "true");
p.put("RcsDB.username", "username");
p.put("RcsDB.password", "password");
context = EJBContainer.createEJBContainer(p).getContext();
context.bind("inject", this);
}
