  • Selenium 致命杀手(有关自动化的通病)

    Do your scripts suffer from the following automation test flaky symptoms?

    • Test randomly fail
    • Works on your machine but not on another machine
    • Test take a long time to run
    • False positives/negatives results
    • Unreliable test run in CI have you contemplating a new career as a sheep herder

    If so, your test might suffer from a common under-diagnosed automation disease known as Stinky Synchronization Syndrome.

    One of the biggest killers of test automation script reliability is the failure to use proper synchronization/wait points in Selenium. Read the rest of this post to learn how to treat this world wide epidemic.

    自动化测试中经常遇到失败的脚本,但是很多情况下,这些失败的脚本是没有意义的,可能是对象没有出现导致的。因为在web程序中对象的显示反应时间是不一致的。不同的网络环境,不同的操作会导致相应的时间的不同。如果避免?

    尽量不用使用以下两种方式等待对象出现:

    1. driver.manage().timeouts().implicitlyWait(GlobalDefinition.WEBELEMENT_LOADING_TIME, TimeUnit.SECONDS);

    2.Thread.sleep();

    推荐使用如下方式进行对象同步操作:

    try{
          WebDriverWait wait = new WebDriverWait(getDriver(),10);
          wait.until(ExpectedConditions.visibility(joeLogo));
          return true; 
        }catch(org.openqa.selenium.NoSuchElementException e){
          return false;
        }
