How to use if/else condition in selenium webdriver?
提问by testing
In selenium webdriver i want to use if/else condition with java. Each steps need to be checked and need to execute one by one. For example
在 selenium webdriver 中，我想在 java 中使用 if/else 条件。每一步都需要检查，需要一一执行。例如
Log.info("Clicking on Reports link");
WebElement menuHoverLink = driver.findElement(By.id("reports"));
actions.moveToElement(menuHoverLink).perform();
Thread.sleep(6000);
In this code, i need to check the id once it present it need to perform the action else it need to skip the test case not to be failed.
在这段代码中，我需要检查 id 一旦它出现就需要执行操作，否则它需要跳过测试用例才不会失败。

if(driver.findElement(By.id("reports").size()!=0){
WebElement menuHoverLink = driver.findElement(By.id("reports"));
actions.moveToElement(menuHoverLink).perform();
}
else{
system.out.println("element not present -- so it entered the else loop");
}
use this one -- if the element is not persent also testcase doesnt fail
使用这个——如果元素不存在，测试用例也不会失败

Use try catch block in your script like
在脚本中使用 try catch 块，例如
Log.info("Clicking on Reports link");
try {
WebElement menuHoverLink = driver.findElement(By.id("reports"));
actions.moveToElement(menuHoverLink).perform();
Thread.sleep(6000);
} Catch(Exception e) {
// Element not found....do not fail my test
}

Option #1:
选项1：
WebElement menuHoverLink = null;
try
{
menuHoverLink = driver.findElement(By.id("reports"));
}
catch(Exception e)
{
}
if (menuHoverLink != null)
{
actions.moveToElement(menuHoverLink).perform();
Thread.sleep(6000);
}
Option #2:
选项#2：
List<WebElement> menuHoverLinks = driver.findElements(By.id("reports"));
if (menuHoverLinks.size() > 0)
{
actions.moveToElement(menuHoverLinks.get(0)).perform();
Thread.sleep(6000);
}
Keep in mind that Thread.sleepby itself may also throw an exception, so you should either catch it inside the method, or add throws Exceptionat the end of the method's declaration.
请记住，Thread.sleep它本身也可能引发异常，因此您应该在方法内部捕获它，或者throws Exception在方法声明的末尾添加。

Try this one . i think this should work
for me it worked
private boolean existsElement(String id) {
try {
driver.findElement(By.id(id));
} catch (Exception e) {
System.out.println("id is not present ");
return false;
}
return true;
}
if(existsElement("reports")==true){
WebElement menuHoverLink = driver.findElement(By.id("reports"));
actions.moveToElement(menuHoverLink).perform();
}
else{
system.out.println("element not present -- so it entered the else loop");
}
