java.lang.IllegalArgumentException: Cannot subclass final class

[mike]

Hi,

I am using the following in my pom.xml

<mockito-all.version>1.9.0-rc1</mockito-all.version>
<powermock.version>1.4.12</powermock.version>

<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.10</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.mockito</groupId>
<artifactId>mockito-all</artifactId>
<version>${mockito-all.version}</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-api-mockito</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-module-junit4</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>

This is my testcase ( not all code):

import org.junit.runner.RunWith;
import org.mockito.Mockito;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

@RunWith(PowerMockRunner.class)
@PrepareForTest(NodeAccess.class)
public class MyTest {

@Test
public void test() throws Exception{


//Mock static
PowerMockito.mockStatic(HifiAccess.class);

.....

}

I execute the test within eclipse ide.
Any ideas why this is not working and I get the error message when I
run the testcase?

java.lang.IllegalArgumentException: Cannot subclass final class
HifiAccess.class

You haven't prepared "HifiAccess" for test?

Hi,

 

I am not sure what you mean by that? I have a:

 

MockitTo.when(HifiAccess.method()) ....

 

Later in method. Or do you mean something else?

 

br,

 

//mike

[mike]

Ah I see what you mean!

 

The annotation:

 

@PrepareForTest(HifiAccess.class)

 

Sorry for faulty example.

 

br,

You're using "PowerMockito.mockStatic(HifiAccess.class);" but HifiAccess is not included in the @PrepareForTest annotation.

I have tried with:

@PrepareForTest(HifiAccess.class)

but I get the same error....

Hmm I cannot see anything wrong with the code. This is really basic stuff so it really ought to work...

Regards,

I tried the following:

http://code.google.com/p/powermock/wiki/MockitoUsage

And it says I should use:

Mockito.when(Static.firstStaticMethod(param)).thenReturn(value);

and I have tried this and I get the same error. I also tried with:

PowerMockito.when(.....)

And I get the same error.
Confusing.

I think in order for anyone to help out more we need more context. Can you send a full unit test class (from package line to ending brace) with a single @Test method that reproduces the issue?

Hi,

Thanks.

Hi,

I received help from a college. Sine I am using testng for testing I need to do the following to mock static method in a final class.

https://code.google.com/p/powermock/wiki/TestNG_usage

What I am missing is an explanation for using the powermock object factory. Anyone with that knowledge that would like to explain :-)
