Error "JUnit version 3.8 or later expected" when trying to execute unit tests in Android Studio

Question

If I try to run my unit tests in Android Studio, I always get this error:

!!! JUnit version 3.8 or later expected:

java.lang.ClassNotFoundException: junit.framework.ComparisonFailure

    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)

    at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:61)

My gradle dependencies look like this:

def google_services = "15.0.1"

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    // for tests
    androidTestImplementation 'junit:junit:4.12'
    androidTestImplementation 'org.powermock:powermock-api-mockito2:1.7.4'
    androidTestImplementation 'org.powermock:powermock-module-junit4:1.7.4'

    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support:support-v4:27.1.1'
    implementation 'com.android.support:gridlayout-v7:27.1.1'
    implementation 'com.android.support:design:27.1.1'

    implementation 'com.michaelpardo:activeandroid:3.1.0-SNAPSHOT'
    implementation 'com.github.rtoshiro.securesharedpreferences:securesharedpreferences:1.2.0'

    implementation 'com.jakewharton:butterknife:8.8.1'
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'

    implementation('com.crashlytics.sdk.android:crashlytics:2.5.2@aar') {
        transitive = true
    }
    implementation 'com.android.support:recyclerview-v7:27.1.1'
    implementation 'com.zcw:togglebutton-library:1.0.0'
    implementation 'com.android.support:exifinterface:27.1.1'
}

My Tests looks like this:

@RunWith(MockitoJUnitRunner.class)
public class MyTest {

    @Test
    public void testTestIt() {
        // some test code
    }
}

I tried all the following "solutions", but none of them worked:

Can someone maybe point me into the right direction?

Some more info:

compileSdkVersion 27
Only one module in the project
Android Studio 3.1.4 on Mac OSX
JRE 1.8.0_152

Did you try to change the order of dependencies inside the pom file so that Android SDK comes after JUnit? — 0xAliHn, Aug 13 '18 at 10:55
@0xalihn I'm not exactly sure what you mean, but I also tried to have the junit:4.12 as the very first dependency in my gradle.build file, but that also didn't work. — L.Butz, Aug 13 '18 at 11:13
yup, in the same boat with Android Studio 3.4.2, also tried all suggestions written in the links, none of them worked — ykonda, Aug 05 '19 at 19:33
