在Android Studio中运行参数化单元测试时，没有发现给定的测试包含错误

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，说明没有测试运行。但是，如果我删除参数化测试，并将它们更改为单独的测试，它就可以工作。

有人能解释一下为什么这行不通吗?Android开发中还不支持参数化单元测试?

下面是堆栈跟踪的错误:

添加到build.gradle:

test {
    useJUnitPlatform()
}

其他回答

我的设置是Android Studio, Junit 4，用robolectric测试。

问题是我将这个noverify设置添加到应用程序级构建中。gradle试图解决Java.lang.VerifyError:从Android Studio运行测试与代码覆盖的糟糕返回类型。(https://github.com/robolectric/robolectric/issues/3023)

移除它就能解决问题。

我在gradle构建依赖列表中添加了一个字符串:

dependencies {
    implementation("org.junit.jupiter:junit-jupiter-params:5.8.0")
    testImplementation(kotlin("test"))
}

重建gradle和一切工作。

记住要添加测试文件:

import org.junit.jupiter.params.ParameterizedTest
2021-09-15 14:21:21

我使用了org.junit.Test包的@Test注释，但我遇到了同样的问题。在构建时添加testimplemimplementation ("org.assertj:assertj-core:3.10.0")之后。Gradle，它成功了。

我犯了这样定义测试的错误

class MyTest {
    @Test
    fun `test name`() = runBlocking {


        // something here that isn't Unit
    }
}

这导致runBlocking返回一些东西，这意味着该方法不是void, junit不认为它是一个测试。这太差劲了。我现在显式地提供一个类型参数来运行阻塞。这不能让我停止疼痛，也不能让我恢复两小时的工作时间但它能确保这种事不会再发生。

class MyTest {
    @Test
    fun `test name`() = runBlocking<Unit> { // Specify Unit


        // something here that isn't Unit
    }
}

找到了在Android Studio中运行测试的方法。显然，使用Gradle Configuration运行它不会执行任何测试。相反，我使用JUnit Configuration。简单的方法是选择要运行的测试类，然后右键单击。然后选择“运行”。之后，您将看到2个运行选项。根据图像选择底部的一个(JUnit)

(注意:如果你找不到2 Run Configuration来选择，你需要先删除你之前使用的配置(Gradle Configuration)。这可以通过点击顶部工具栏中的“选择运行/调试配置”图标来完成。
