Java Cucumber在@before hook:NoClassDefFoundError期间失败

打开Chrome浏览器后，Automation framework将不会继续执行.feature文件中的步骤（然后在之后关闭）

GenericStepImplementation.java代码

@Before
public void setUp() throws ConfigurationException, org.apache.commons.configuration.ConfigurationException
{
    System.setProperty("webdriver.chrome.ChromeDriver","C:\\Automation\\Webdrivers\\chromedriver.exe");
    driver = new ChromeDriver();
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    driver.manage().window().maximize();
    config = new XMLConfiguration("sample-object-config.xml");
}

package test_runner;

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

@RunWith(Cucumber.class)
@CucumberOptions(
glue={"code_bindings"},
features="src/test/resources/features", 
plugin = {"pretty", "html:target/cucumber-html-report"})

public class RunAutoTest {

}

RunAutoTest.java代码

@Before
public void setUp() throws ConfigurationException, org.apache.commons.configuration.ConfigurationException
{
    System.setProperty("webdriver.chrome.ChromeDriver","C:\\Automation\\Webdrivers\\chromedriver.exe");
    driver = new ChromeDriver();
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    driver.manage().window().maximize();
    config = new XMLConfiguration("sample-object-config.xml");
}

package test_runner;

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

@RunWith(Cucumber.class)
@CucumberOptions(
glue={"code_bindings"},
features="src/test/resources/features", 
plugin = {"pretty", "html:target/cucumber-html-report"})

public class RunAutoTest {

}

样本特征

Feature: Automation Test

@Login-Successful
Scenario: Login (Successful)
Given I go to "www.yahoo.com" URL
    Then I enter "m@yahoo.com" into "login.username" field and click tab
    Then I enter "1234567890" into "login.password" text field
    Then I clicked on "login.loginlink" login button
    Then I wait for "15" seconds
    And I will capture the page named "Login-Successful"

作为JUnit测试运行后，Chrome浏览器已打开，但未执行Sample.feature文件中的步骤。控制台还显示：

只要换个颜色就行了

System.setProperty（“webdriver.chrome.ChromeDriver”，“C:\\Automation\\Webdrivers\\ChromeDriver.exe”）

您需要将

系统中的关键字。setProperty

行从

ChromeDriver

更改为

驱动程序，即更改：

System.setProperty("webdriver.chrome.ChromeDriver","C:\\Automation\\Webdrivers\\chromedriver.exe");

致：


当类在编译期间存在，但在运行时不存在时，会发生此异常

请确保您的类路径包含
org/apache/commons/collections/CollectionUtils
。类路径中可能缺少库
commons collection
。
似乎缺少apache commons collection库。您可以尝试将其添加到您的构建中。您可以从as获取库，以便将其添加到您的构建中，这取决于您使用的内容（maven、gradle等）@CalvinIyer我已下载commons-collections4-4.2 jar并添加到java构建路径。但它仍然不起作用。还有其他建议吗？根据上面的错误，您需要
commons集合
而不是
commons-collection4
库。@CalvinIyer等待。。我还会下载commons collection jar文件只是为了添加到java构建路径吗？它不起作用。同样的结果（还有其他建议吗？改成什么？我已经下载了commons-collections4-4.2 jar并添加到java构建路径。它仍然不起作用。还有其他建议吗？我看到你找到了上面的答案。为你高兴！
