运行Junit 5 Android测试时无法解析的参考Jupiter和assertTrue

编程问答 2022-08-13

问题描述

我正在尝试在Kotlin中创建一个处理Bitmap的Android测试类，但是由于这些错误，我无法运行测试。它们仅在 androidTest 中的任何测试类中发生，但 test 中的简单JVM测试运行没有问题。

首先，这就是我的测试类的样子

import android.graphics.Bitmap
import androidx.test.core.app.ApplicationProvider
import org.junit.jupiter.api.Assertions.assertTrue

class RoundImageTest {

    @org.junit.jupiter.api.Test
    fun imagesRatio() {
        // test with square images
        val squareBitmap: Bitmap = Bitmap.createBitmap(
             164,164,Bitmap.Config.ARGB_8888
        )
        assertTrue(squareBitmap.height == squareBitmap.width)
    }
}

按照指定的说明here，我将其保存在项目的 build.gradle

中 
dependencies {
    classpath 'com.android.tools.build:gradle:4.0.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'eu.appcom.gradle:android-versioning:1.0.2'
    classpath 'com.github.dcendents:android-maven-gradle-plugin:2.1'
    classpath "io.gitlab.arturbosch.detekt:detekt-gradle-plugin:1.10.0"
    classpath "org.jlleitschuh.gradle:@R_159_5027@-gradle:9.2.1"
    classpath("de.mannodermaus.gradle.plugins:android-junit5:1.6.2.0")
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

，这在我的应用程序的 build.gradle

中 
apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

apply plugin: 'eu.appcom.gradle.android-versioning'

现在，当我尝试运行测试时，这是 Build Output 显示给我的

解决方法

显然，我要做的就是改变

到
