Question

我是第一次创建Cucumber Project。我正在使用Eclipse。我还没有创建Maven项目，我正在遵循一些教程并创建了Java Project，在这里我手动添加了JAR文件。 JAR文件列表：黄瓜芯-4.0.0.jar 黄瓜java-4.0.0.jar 黄瓜junit-4.0.0.jar 黄瓜jvm-deps-1.0.6.jar 小黄瓜6.0.0.jar junit-4.12.jar mockito-all-1.10.19.jar

我已经创建了Feature File：功能：Google主页此功能可验证Google主页上的功能

Scenario: Check that main elements on Google Homepage are displayed
Given I launch Chrome browser
When I open Google Homepage
Then I verify that the page displays search text box
And the page displays Google Search button
And the page displays Im Feeling Lucky button

我已经创建了TestRunner类

package testRunners;

import org.junit.runner.RunWith;
import cucumber.api.junit.Cucumber;
import cucumber.api.CucumberOptions;

@RunWith(Cucumber.class)
@CucumberOptions(,features="resources/features", glue="")
public class TestRunner_FirstScenario {
}

我尝试将此类作为JUnit Test运行。然后我得到错误，我将在帖子末尾添加错误。

我不认为原因是我没有StepDefinitions类。我认为JAR版本存在一些兼容性问题，但我使用的是最新版本。

错误是：

TestRunner_FirstScenario
testRunners.TestRunner_FirstScenario
initializationError(testRunners.TestRunner_FirstScenario)
java.lang.NoClassDefFoundError: gherkin/IGherkinDialectProvider

如果您在Maven Central上检查了黄瓜的POM，您会发现它依赖于Gherkin 5.1.0而不是6.0.0。

https://search.maven.org/artifact/io.cucumber/cucumber-jvm/4.0.0/jar

我建议您使用一种工具进行依赖项管理，而不要手动收集jar文件。 maven和gradle都是绝佳的选择。

JUnit测试黄瓜中的InitializationError（NoClassFound-IGherkinDialectProvider）
