java – Selenium WebDriver getText

I have a < div name = "mydiv" > 0 < / div >

I try to write a test with 0 text in mydiv Use webdriver, which is:

String text =  webDriver.findElement(By.xpath("//div[@name='myDiv']")).getText();

But I ended up with an empty string Shouldn't I use gettext () to get the contents of div?

Solution

I have the same problem; A little digging reminds me of this:

When you try to call webelement #gettext() on an element whose CSS property "display" is set to "None", the htmlunitdriver (obviously Firefox driver) will return an empty string

This is my solution:

public void assertContainsText(final By by,final String value) { 
    browser.waitTillElementPresent(by);
        Boolean result = new webdriverwait(getWebDriver(),Browser.DEFAULT_WAIT_TIMEOUT_SECONDS).until(new ExpectedCondition<Boolean>() {
            @Override
            public Boolean apply(WebDriver arg0) {
                WebElement elem = arg0.findElement(by);
                String text = "";
                if (elem.isDisplayed()) {
                    text = elem.getText();
                } else {
                  //have to use JavaScript because HtmlUnit will return empty string for a hidden element's text
                    text = (String) executeScript("return arguments[0].innerHTML",elem);
                    text = text.replace("<BR></BR>","\n"); //scary
                }
                return text.contains(value);
            }
        });
        Assert.assertTrue(by.toString() + " contains value ["+value+"]",result);
}

Yes, it's as ugly as sin Note text Replace ("< br > < / BR >") – this is because HTML tags are not escaped when the original data is pulled out If you call #gettext () on an element, the webdriver will 'unescape' well

I now ask our IT staff to install X - Windows on our CI server so that we can run Firefox driver All we get from htmlunitdriver is trouble, and the startup speed is very slow
