@before 钩子期间黄瓜失败：NoClassDefFoundError

Question

Chrome 浏览器打开后，自动化框架将不会继续执行 .feature 文件中的步骤（然后关闭）

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");
}

RunAutoTest.java 代码

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 {

}

Sample.feature

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 Test 运行后，Chrome 浏览器已打开，但未执行 Sample.feature 文件中的步骤。控制台也显示：

*Feature: Automation Test

Answer 1

您需要将System.setProperty 行中的关键字从ChromeDriver 更改为driver，即更改：

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

收件人：

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

Answer 2

https://docs.oracle.com/javase/7/docs/api/java/lang/NoClassDefFoundError.html

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。类路径中可能不存在库commons-collections。

Answer 3

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