小代码改进

 package MonitorTest; import java.io.BufferedReader; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.InputStreamReader; import java.util.ArrayList; import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.support.ui.ExpectedCondition; import org.openqa.selenium.support.ui.Select; import org.openqa.selenium.support.ui.WebDriverWait; public class MonitorTest_improve {  public static void main(String[] args) throws InterruptedException, IOException{   //存储监控 名称的文件地址   String fileUrl="D:\\bukejian\\tmp.txt";   //访问地址   String url=;   ArrayList<String> list = new ArrayList<String>();   String encoding="GBK";      File file = new File(fileUrl);   if(file.isFile() && file.exists()){             InputStreamReader read = new InputStreamReader(             new FileInputStream(file),encoding);             BufferedReader bufferedReader = new BufferedReader(read);             String lineTxt = null;             while((lineTxt = bufferedReader.readLine()) != null){                list.add(lineTxt);             }             read.close();          }else{           System.out.println("No exist");          }             System.setProperty("webdriver.firefox.bin", "D:/bukejian/Mozilla Firefox/firefox.exe");   WebDriver dr = new FirefoxDriver();    dr.get(url);   WebElement submit=(new WebDriverWait(dr,10)).until(new ExpectedCondition<WebElement>(){       @Override       public WebElement apply(WebDriver d){        return d.findElement(By.cssSelector("input[type=\"submit\"]"));       }      });   dr.findElement(By.name("login_username")).clear();   dr.findElement(By.name("login_username")).sendKeys("bukejian");   dr.findElement(By.name("login_password")).clear();   dr.findElement(By.name("login_password")).sendKeys("bukejian");   submit.click();      int j=0;   for(String a :list){    (new WebDriverWait(dr,10)).until(new ExpectedCondition<WebElement>(){        @Override        public WebElement apply(WebDriver d){         return d.findElement(By.linkText("Add"));        }       }).click();        WebElement select=(new WebDriverWait(dr,10)).until(new ExpectedCondition<WebElement>(){        @Override        public WebElement apply(WebDriver d){         return d.findElement(By.name("type_select"));        }       });    new Select(select).selectByVisibleText("Graph");        WebElement graph_id=(new WebDriverWait(dr,10)).until(new ExpectedCondition<WebElement>(){        @Override        public WebElement apply(WebDriver d){         return d.findElement(By.id("local_graph_id"));        }       });       new Select(graph_id).selectByVisibleText(a);              (new WebDriverWait(dr,10)).until(new ExpectedCondition<WebElement>(){        @Override        public WebElement apply(WebDriver d){         return d.findElement(By.cssSelector("input[type=\"button\"]"));        }       }).click();                     //dr.findElement(By.cssSelector("input[type=\"submit\"]")).click();//提交                  System.out.println(j+"="+a);       j++;       }   dr.close();    } }

全加上了 等待10s，用取消操作验证了下倒是不会超时报错了

Exception in thread “main” org.openqa.selenium.NoSuchElementException: Unable to locate element: {“method”:”bukejian”,”selector”:”bukejian”}

之前会报这种错误，应该是没找到元素超时了，这次所有元素都最多等待10s应该不会报错了吧
