cannot resolve symbol PowerMockRunner

Question

I'm trying to use Powermock for the first time

I use build.gradle and added:

dependencies {
...
    testCompile 'org.mockito:mockito-all:1.9.5'
    testCompile 'org.powermock:powermock-api-mockito:1.5.5'

}

now I look at my test class which has:

import org.junit.Before;
import org.junit.runner.RunWith;
import org.mockito.Matchers;
import org.powermock.core.classloader.annotations.PrepareForTest;


@RunWith(PowerMockRunner.class)
@PrepareForTest(GeoUtils.class)

and get this error:

@RunWith(PowerMockRunner.class)
             ^
cannot resolve symbol PowerMockRunner 

how come it resolves PrepareForTest and not PowerMockRunner ?

Solution 1

You need to import PowerMockRunner as follows:

import org.powermock.modules.junit4.PowerMockRunner;

Solution 2

PowerMockRunner is part of powermock-module-junit4.jar. You need to explicity import this jar

You could specify the dependency for this jar as per your requirement. Refer to this link.

Solution 3

You just need to add the gradle dependency

testCompile "org.powermock:powermock-module-junit4:1.6.4"

or if you're use Android Studio version 3+

testImplementation "org.powermock:powermock-module-junit4:1.6.4"

Solution 4

I faced this error because I had only the first of the following dependencies added in my pom.xml. Please ensure you add both the following maven dependencies for PowerMock to your pom.xml.

<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-api-mockito</artifactId>
<version>1.6.3</version>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-module-junit4</artifactId>
<version>1.6.3</version>
</dependency>

Solution 5

I also faced with a similar error. Although the jars are already in the classpath, eclipse didn't suggest to import PowerMockRunner class. It was giving error "Class cannot be resolved to a type". I had to manually add the import "org.powermock.modules.junit4.PowerMockRunner".

Because you imported PrepareForTest, but you forgot to import PowerMockRunner?

it doesn't give me any suggestion to PowerMockRunner import as it did with PrepareForTest. So I guess it cannot resolve its import anyhow. no?what is it?

[David Conrad]

I believe it should be org.powermock.modules.junit4.PowerMockRunner. If it doesn't accept the import, the dependency must not have been resolved for some reason.

thanks. please write an answer and I'll vote you

I already have this import. But still i didn't work. I have the jar as well.
