Exception in thread “main” org.openqa.selenium.NoSuchFrameException: no such frame using Selenium + Java + Chromedriver in Docker with Centos 7

问题

I have a test that executed in my windows machine works fine but now im trying to make it works in a docker with centos 7, java version 1.8.0_272, chrome and chromedriver 87.0 but it just dont works, this what the stacktrace says:

In the line seleniumjavapqr.pqrMovil.pqrMovilRegistrar(pqrMovil.java:30) my code says:

driver.switchTo().frame(0);

I don't know how important it is, but, in the stacktrace line 12 where expect to be the selenium info there's just 'unknown'

As important information i can say that i import selenium-server-standalone.1.141.59.jar as a library in my test jar and again, i don't know if this is ok.

回答1:

Instead of switching within the <iframe> using an index as:

driver.switchTo().frame(0);

Ideally, you have to induce WebDriverWait for the frameToBeAvailableAndSwitchToIt() and you can use either of the following Locator Strategies:

• Using frameName:

  new WebDriverWait(driver, 20).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.name("frame_name")));
  

• Switch frameID:

  new WebDriverWait(driver, 20).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.id("frame_id")));
  

• Using frameCssSelector:

  new WebDriverWait(driver, 20).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.cssSelector("frame_cssSelector")));
  

• Using frameXpath:

  new WebDriverWait(driver, 20).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.xpath("frame_xpath")));

Reference

You can find a couple of relevant discussions in:

• Ways to deal with #document under iframe
• Is it possible to switch to an element in a frame without using driver.switchTo().frame(“frameName”) in Selenium Webdriver Java?
