在Android Studio运行参数化单元测试时出现“找不到给定包含项错误”的问题

我尝试在Android Studio中运行参数化单元测试，如下所示：

import android.test.suitebuilder.annotation.SmallTest;  

import junit.framework.TestCase;    

import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.JUnit4;
import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameter;
import org.junit.runners.Parameterized.Parameters;  

import java.util.Arrays;
import java.util.Collection;    

@RunWith(Parameterized.class)
@SmallTest
public class FibonacciTest extends TestCase {
    @Parameters
    public static Collection<Object[]> data() {
        return Arrays.asList(new Object[][] {
                {0, 0}, {1, 1}, {2, 1}, {3, 2}, {4, 3}, {5, 5}, {6, 8}
        });
    }   

    @Parameter // first data value (0) is default
    public /* NOT private */ int fInput;    

    @Parameter(value = 1)
    public /* NOT private */ int fExpected; 

    @Test
    public void test() {
        assertEquals(fExpected, Fibonacci.calculate(fInput));
    }
}

结果是一个错误，指出 No Test Run。但是，如果我删除参数化测试，并将它们更改为单个测试，则可以正常工作。

有人能解释一下为什么这不起作用吗？Android开发中还不支持参数化单元测试吗？

以下是具有堆栈跟踪的错误：

对于那些在添加建议解决方案时遇到错误：表达式“test”不能作为函数调用，请尝试以下方法：

tasks.withType<Test> {
    useJUnitPlatform()
}

2021年适用于KMM设置。

如果您正在使用Intellij并且想要使用Gradle，则需要将以下内容添加到build.gradle文件的dependencies部分：

testImplementation("org.junit.jupiter:junit-jupiter-api:5.4.2")
testRuntimeOnly("org.junit.jupiter:junit-jupiter-engine:5.4.2")
谢谢。我不小心使用了junit-platform-engine而不是junit-jupiter-engine，这显然导致了这个问题。 - Martin Vysny
谢谢！我漏掉了testRuntimeOnly("org.junit.jupiter:junit-jupiter-engine:5.7.0")声明。 - Adrian

我最近遇到了这个问题，经过深入研究，我发现我正在使用junit库中的@Test注释。然而，我的build.gradle文件声明了另一个测试库。
因此，当我从build.gradle中存在的Test库中使用@Test注释时，它可以工作。

您可以检查您的方法是否为私有。浪费了很多时间来修复这个愚蠢的错误...

对我来说，出现错误消息的原因是我不小心在src/test/kotlin测试目录下添加了一个.java测试文件。将该文件移动到正确的目录src/test/java后，测试再次按预期执行。

给定包含项的没有找到测试

在使用 JUnit 4 时，我在 Intellij 中遇到了类似的错误。

解决方法是从 build.gradle.kts 中删除相关内容。

    test {  useJUnitPlatform()  }

结果是 build.gradle.kts

plugins {
    kotlin("jvm") version "1.8.0"
    application
    id("org.jetbrains.kotlin.plugin.serialization") version "1.5.31"
}

group = "org.example"
version = "1.0-SNAPSHOT"

repositories {
    mavenCentral()
}

dependencies {
    implementation("com.google.code.gson:gson:2.8.8")
    implementation("org.jetbrains.kotlinx:kotlinx-serialization-json:1.3.0")
    implementation ("org.apache.poi:poi-ooxml:5.1.0")
    testImplementation(kotlin("test"))
    testImplementation("junit:junit:4.13.1")
}



kotlin {
    jvmToolchain(11)
}

application {
    mainClass.set("MainKt")
}

测试工作正常

import org.junit.Assert


class MainKtTest1 {
    @org.junit.Test
    fun firstTest() {
        Assert.assertEquals("2*2=4", 2 * 2, 4)
    }

}

难以置信，但在我的情况下问题出在我为测试用例创建的包名错误。它不应该包含大写字母。例如，以下案例是不正确的： "PackageName" "Packagename" "packageName"

3
在我的情况下，问题出现在使用Kotlin和IDEA 2020.3编写代码时。尽管在build.gradle.kts中有正确的条目，但问题在于IDEA IDE（Alt + Insert）生成测试函数时。它生成以下代码：
@Test
   internal fun name () {
     TODO ("Not yet implemented")
   }

去掉 "internal" 修饰符后，问题将会得到解决：

@Test
   fun name () {
     TODO ("Not yet implemented")
   }
2

对于JUnit 5，我们应该使用导入 org.junit.jupiter.api.Test 并且还应该使用@ExtendWith而不是@RunWith。

2
我不得不更改@Test库。起初，我导入了org.junit.Test，然后出现了异常。然后我将其更改为org.junit.jupiter.api.Test，它就正常工作了。
这解决了我的问题！谢谢！ - SJoe
