java - Spring MVC : Testing with selenium failing with commons-io not found(it exists)

Question

我正在尝试使用 Selenium 测试 Spring-MVC 应用程序。不幸的是，到目前为止，我还没有足够的运气来启动和运行它。当我尝试使用以下命令使用干净的 tomcat 运行它时，它会提示找不到 commons-io。

如果我直接开始测试，那么登录页面是不会加载的。

启动 Apache :

mvn clean tomcat7:run

错误日志:

[ERROR] Failed to execute goal org.apache.tomcat.maven:tomcat7-maven-plugin:2.2:run (default-cli) on project SOFTWARE: Could not start Tomcat: Failed to start component [StandardServer[-1]]: Failed to start component [StandardService[Tomcat]]: Failed to start component [StandardEngine[Tomcat]]: A child container failed during start -> [Help 1]

带有 commons-io 的 POM.xml:

<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
</dependency>


    <plugin>
        <groupId>org.apache.maven.plugins</groupId>

            <showDeprecation>true</showDeprecation>
        </configuration>
    </plugin>

如果我直接尝试给出以下命令:

mvn clean test -Dtest=SeleniumLoginFrontendTest

登录页面未加载，出现此错误:

Tests in error: 
  SeleniumLoginFrontendTest.startTest:25 » NoSuchElement Unable to locate elemen...

SeleniumLoginFrontendTest.java :

  public class SeleniumLoginFrontendTest  {

        private WebDriver browser;

        @Before
        public void setup() {
            browser = new FirefoxDriver();
        }

        @Test
        public void startTest() {
            browser.get("http://localhost:8080/login");
      --> Below is line-25  

browser.findElement(By.id("j_username")).sendKeys("");
        browser.findElement(By.id("j_password")).sendKeys("");

            browser.findElement(By.id("loginButton")).click();
            browser.findElement(By.id("account")).click();
        }

        @After
        public void tearDown() {
          //  browser.close();
        }

    }

那么，我究竟做错了什么？你能帮忙的话，我会很高兴。谢谢。 :-)

更新所以，我确实将 commons-io 库设置为 2.2 版，但这没有帮助。

尝试明确指定一个版本:

<dependencies>
    ...
    <dependency>
        <groupId>commons-io</groupId>
        <artifactId>commons-io</artifactId>
        <version>2.2</version>
    </dependency>
    ...
</dependencies>
