Selenium: JUnit4: WebDriver: IE: 使用 IE 时出现 NoSuchElementException

Question

I recorded my test in Selenium IDE; it runs fine in Firefox and Chrome. When I run it in IE 9, I keep getting this error. I am new to coding and am having trouble finding an answer to this. If anyone can explain to me in lay man's terms what is happening/why this may be the case, I'd appreciate it.

org.openqa.selenium.NoSuchElementException: Unable to find element with css selector == BODY (WARNING: The server did not provide any stacktrace information)

Java Code:

assertTrue(driver.findElement(By.cssSelector("BODY")).getText().matches("^[\\s\\S]*Final[\\s\\S]*$"));

Answer 1

I would suggest printing out driver.getPageSource() before the call and check to see if the html that is on the current page matches your expectations.

If it does match what you'd expect then I'd print out the text content of all of the tags that match By.cssSelector("BODY") and see if any of them contain the text that you'd expect.

This will narrow down where the error is - you might need to find another way of finding this element.

Answer 2

Internally By uses XPath and casing matters with internet explorer.

Try using

assertTrue(driver.findElement(By.cssSelector("body")).getText().matches("^[\\s\\S]*Final[\\s\\S]*$"));

instead of

assertTrue(driver.findElement(By.cssSelector("BODY")).getText().matches("^[\\s\\S]*Final[\\s\\S]

*$"));

I believe that should work for you.

Answer 3

IE browser doesn't support Case-insensitive CSS attribute selectors. Try to use

driver.findElement(By.cssSelector("body"));
