未找到类：IntelliJ中的空测试套件 [英] Class Not Found: Empty Test Suite in IntelliJ

问题描述

我刚刚在我的大学开始计算机科学课程，而且我在使用IntelliJ时遇到了一些问题。当我尝试运行单元测试时，我收到消息

I'm just starting the computer science program at my college, and I'm having some issues with IntelliJ. When I try to run unit tests, I get the message

Process finished with exit code 1
Class not found: "edu.macalester.comp124.hw0.AreaTest"Empty test suite.

我还在屏幕左侧看到一条标题为未找到测试的消息。我的测试代码在这里：

I also see a message entitled "No tests were found" on the left side of my screen. My test code is here:

package edu.macalester.comp124.hw0;


import org.junit.Test;
import static org.junit.Assert.*;

public class AreaTest {

    @Test
    public void testSquare() {
    assertEquals(Area.getSquareArea(3.0), 9.0, 0.001);
    }

    @Test
    public void testCircle() {
    assertEquals(Area.getCircleArea(3.0), 28.2743, 0.001);
    }
}

我的项目代码在这里：

package edu.macalester.comp124.hw0;

import java.lang.Math;
public class Area {

/**
 * Calculates the area of a square.
 * @param sideLength The length of the side of a square
 * @return The area
 */
public static double getSquareArea(double sideLength) {
    // Has been replaced by correct formula
    return sideLength * sideLength;
}

/**
 * Calculates the area of a circle.
 * @param radius The radius of the circle
 * @return The area
 */
public static double getCircleArea(double radius) {
    // Replaced by correct value
    return radius * 2 * Math.PI;
}

}

如何让我的测试到工作？提前致谢。我正在使用最新版本的IntelliJ IDEA CE。

How can I get my tests to work? Thanks in advance. I'm using the most recent version of IntelliJ IDEA CE.

推荐答案

有相同的消息。我不得不删除运行/调试配置。

Had the same message. I had to remove the Run/Debug configuration.

在我的情况下，我之前将单元测试作为本地测试运行。之后我将测试移到androidTest包并尝试再次运行它。 Android Studio记得最后一次运行配置，因此它尝试再次运行它作为本地单元测试产生相同的错误。

In my case, I ran the unit test as a local test before. After that I moved my test to the androidTest package and tried to run it again. Android Studio remembered the last run configuration so it tried to run it again as a local unit test which produced the same error.

删除配置并再次运行测试后生成了一个新的配置并且有效。

After removing the config and running the test again it generated a new configuration and worked.
