android - 在 Android Studio 中运行参数化单元测试时，没有找到给定的测试包括错误

Question

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，并将它们更改为单独的测试，它就会起作用。

谁能阐明为什么这不起作用？ Ar 参数化单元测试在 Android 开发中还不支持吗？

下面是堆栈跟踪的错误:

如果您使用的是 JUnit 5+，请确保从正确的库中导入 @Test 注释:

导入 org.junit.jupiter.api.Test

不是

导入 org.junit.Test
