使用 Junit5

如何解决使用 Junit5

我必须测试当前位置是否靠近某个特定位置。在我的测试课中，我试图通过设置经度和纬度来创建该特定位置，在应用程序中，这些数据来自后端。在我的测试课中，我手动输入它们。因为我的函数重复了太多次，所以我必须使用 junit5 提供的 ParametizedTest。但是使用 junit5 使我无法 RunWith(RoboElectricTestRunner.class)。相反，我开始使用 mannodermaus 插件通过 junit5 进行 Android 测试。它带来了另一个我无法弄清楚的问题，我的 Location 对象现在返回 null 而不是设置 lon 和 lat

 private fun strings(): Stream<String?>? {
            return Stream.of( "foo","bar")
        }
    
        @ParameterizedTest
        @MethodSource("strings")
        fun updateLocation(input: String)  {      
    
            var lat = 12.494831
            var lon = 83.49899
            val startLocation = Location("start")
            startLocation.latitude = lat
            startLocation.longitude = lon
    
            **println("startLocation = $startLocation") **//returns null****
    }

在它工作正常之前，当我使用 JUnit4 和 @RunWith(RobolectricTestRunner.class) 时。现在我使用 junit5 和 mannodermaus 插件。

我的 build.gradle 文件如下所示。

  apply plugin: 'de.mannodermaus.android-junit5'

apply from: rootProject.file('buildscripts/sonar.gradle')

android.buildFeatures.dataBinding = true

    //If your minSdkVersion is 24 or higher,then your issue will be resolved on its own,because VectorDrawables have full support starting with this API.
