我正在编写第一个较大的Groovy应用程序,我想定义几个单元测试,但无法执行这些测试。我一直得到一个异常java.lang.NoSuchFieldError: NOOP
。我把它归结为一个非常简单的例子,看起来像这样:
package example_project;
import org.junit.jupiter.api.Assertions
import org.junit.jupiter.api.Test
import groovy.test.GroovyTestCase
public class FirstUnitTest extends GroovyTestCase {
@Test
void testJunitTestExecution() {
Assertions.fail("Heureka - this test got executed!")
}
}
这个“单元测试”应该可以在Eclipse中或通过Maven执行。
当我在Eclipse中执行时(使用“运行为... --> JUnit Test”using JUnit 5 test runner)我得到异常
java.lang.NoSuchFieldError: NOOP

当通过Maven执行时(使用“mvn test”),

所以-显然是同样的错误,即使没有堆栈跟踪。

我正在使用Groovy v4.0.12,Eclipse 2023-06(v4.28.0)和Groovy Plugin和Maven v3.9.4。
我错过了什么?为什么我的测试方法没有被执行?

在花了一天的时间摆弄这个BS之后,我放弃了,现在我使用JUnit 4。
在Eclipse中将TestRunner设置切换到JUnit 4后,UT立即找到并正确执行。在加上
对于我的pom.xml,它也被正确地找到并通过
mvn test
执行。不幸的是--我不得不说--这与我以前使用JUnit-5 / Jupiter的经验相匹配。到目前为止,我 * 从来没有 * 过一个项目,让事情与JUnit 5一起工作 * 不是 * 一个麻烦,而与JUnit 4一起工作总是很容易。当然,理论上JUnit 5有一些很酷的特性,但恕我直言,它们根本不值得这样的问题!YMMV,但我想我会简单地坚持JUnit 4。
