我正试图为我的类运行一个测试"正弦；(用来计算浮子的正弦(，但当我试图运行这个测试来生成Cobertura的覆盖率报告时，它不起作用，我真的不知道为什么！你有什么建议或解释吗？(我使用cmd:mvn-cobertura:cobertura(
-这是我的测试：
import static org.junit.Assert.*;
import org.junit.Test;
public class SinusTest {
Sinus test = new Sinus();
@Test
public static void Sinuszero() {
Sinus test = new Sinus();
assertTrue(test.sin(23) == 5);
}
}
结果是：
[INFO]

那么问题出在哪里呢？有什么想法吗？下面是我的pom.xml：

您的测试是基于junit4-api的。但是从你的pom.xml中，你有junit5依赖项。
删除jupiter依赖项就可以了。
关于cobertura，当您在java8上运行时，您最好迁移到JaCoCo，因为java版本高于7的cobertur有缺陷。
首先，阅读文档。插件的行为不是魔术。https://maven.apache.org/surefire/maven-surefire-plugin/examples/junit-platform.html#Provider_Selection您使用的是JUnit4注释，但POM有两个依赖项：JUnit4和JUnit5。Surefire插件采用首选项并忽略JUnit4 runner。Jupiter的JUnit5运行程序无法理解代码中的JUnit4注释，因此无法找到可执行源。您可以使用JUnit5 Vintage依赖项，而不是JUnit5 Jupiter。
