I try to set up junit, mokito and powermock together but when I ran a test I get ClassNotFoundException :(

testCompile 'junit:junit:4.12'
testCompile 'org.mockito:mockito-core:2.7.22'
androidTestCompile 'org.mockito:mockito-core:2.7.22'
androidTestCompile "org.mockito:mockito-android:2.7.22"

testCompile 'org.robolectric:robolectric:3.3.2'
testCompile 'org.hamcrest:hamcrest-core:1.3'

testCompile 'org.powermock:powermock-core:1.6.6'
testCompile 'org.powermock:powermock-module-junit4:1.6.6'
testCompile 'org.powermock:powermock-module-junit4-rule:1.6.6'
testCompile 'org.powermock:powermock-api-mockito:1.6.6'
testCompile 'org.powermock:powermock-classloading-xstream:1.6.6'`

I also tried adding cglib by adding:

testCompile 'cglib:cglib:3.1'
testCompile 'cglib:cglib-nodep:3.1'

but without of lack.

could any one share working configuration or point me out what is wrong.

My stacktrace when I ran a test:

PowerMock 1.6 isn't compatible with Mockito 2.7 (take a look at https://github.com/powermock/powermock/wiki/Mockito#supported-versions)

You should use PowerMock 1.7.0RC2 (or 1.7.0RC3 if 1.7.0RC2 doesn't work), and also use powermock-api-mockito2 instead of powermock-api-mockito.

That's what worked for me: 

testCompile 'junit:junit:4.12'
testCompile 'org.mockito:mockito-core:2.8.0'
testCompile 'org.powermock:powermock-api-mockito2:1.7.0RC2'
testCompile 'org.powermock:powermock-module-junit4:1.7.0'
testCompile 'org.powermock:powermock-core:1.7.0'
testCompile 'org.powermock:powermock-module-junit4-rule:1.7.0'

using Mockito2 fixed the problem for me.

  • There is no mockito-core:2.8.0 available. Can you post the correct version? – KumarAnkit Dec 29 '18 at 06:11

    I was able to get it working with this combination: `testCompile 'junit:junit:4.12'` . `testCompile 'org.mockito:mockito-core:2.9.0'` . `testCompile 'org.powermock:powermock-api-mockito2:1.7.0RC2'` `testCompile 'org.powermock:powermock-module-junit4:1.7.0'` . `testCompile 'org.powermock:powermock-core:1.7.0'` . – yokeho Jan 30 '19 at 00:33
  • use `testImplementation` instead of `testCompile` as it has been deprecated – Mario Codes Jun 04 '20 at 10:00

I'm using Kotlin 1.2.61/mockito 2.15 and powermock 1.7.0RC2 DID NOT work me. The set of dependencies that did the trick for me is:

dependencies {
    testImplementation "junit:junit:4.12"
    testImplementation "org.mockito:mockito-core:2.15.0"
    testImplementation "io.kotlintest:kotlintest:2.0.7"
    testImplementation 'org.powermock:powermock-module-junit4-rule:2.0.0-beta.5'
    testImplementation 'org.powermock:powermock-core:2.0.0-beta.5'
    testImplementation 'org.powermock:powermock-module-junit4:2.0.0-beta.5'
    testImplementation 'org.powermock:powermock-api-mockito2:2.0.0-beta.5'
}

You should use PowerMock 1.7.+ (it's always better to use the last version), and also use powermock-api-mockito2 instead of powermock-api-mockito.

testImplementation "org.powermock:powermock-api-mockito2:${versions.powermock}"
