Question

如果我尝试在Android Studio中运行单元测试，则总是会收到此错误：

!!! JUnit version 3.8 or later expected:

java.lang.ClassNotFoundException: junit.framework.ComparisonFailure

我的gradle依赖项看起来像这样：

def google_services = "15.0.1"

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

    // for tests
    androidTestImplementation 'junit:junit:4.12'

    implementation 'com.zcw:togglebutton-library:1.0.0'
    implementation 'com.android.support:exifinterface:27.1.1'
}

我的测试如下：

@RunWith(MockitoJUnitRunner.class)
public class MyTest {

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

我尝试了以下所有“解决方案”，但没有一个起作用：

有人可以指出我正确的方向吗？

compileSdkVersion 27
项目中只有一个模块
Mac OSX上的Android Studio 3.1.4

尝试在Android Studio中执行单元测试时出现错误“预期JUnit版本3.8或更高版本”
