How to use getPrivateLocalAddress method of org.openqa.selenium.net.NetworkUtils class

I ran into a similar issue. The click method worked on other pages, then didn't work at all on a particular page.

A race condition caused the issue:

1. HTML content is rendered with the button disabled.
2. The selenium web driver script was executed before the javascript onload event was triggered (Or finished executing). So the button.click would occur on a disabled element. And nothing would happen.
3. Then the javascript onload event would trigger (or finish executing) and the javascript would enable the button.
4. I looked at the page and couldn't figure out why my code wasn't working because the button appeared to be enabled upon inspection, and if I manually clicked the button, it worked.

Once I figured out that it was a timing issue, I found the solution here: How can I get Selenium Web Driver to wait for an element to be accessible, not just present?

To paraphrase the solution in Ruby:

//This will not return the button until it is enabled.
button = driver.find_element(:xpath,  "//button[@id='myButtonId' and not(@disabled)]")
button.click

You can redirect the output to a file or just discard it:

            // redirect console output from chromedriver to the file chromedriver_log.txt in the target folder
            DriverService.Builder<ChromeDriverService, ChromeDriverService.Builder> serviceBuilder = new ChromeDriverService.Builder();
            ChromeDriverService chromeDriverService = serviceBuilder.build();
            chromeDriverService.sendOutputTo(new FileOutputStream("target/chromedriver_log.txt", true));

            webDriver = new ChromeDriver(chromeDriverService, options);

If you want to just discard the output then use NullOutputStream.NULL_OUTPUT_STREAM insted off new FileOutputStream("target/chromedriver_log.txt", true)

For the current htmlUnit 2.13, setting options is slightly different from what maxmax has provided:

final WebClient webClient = new WebClient(BrowserVersion.CHROME);
webClient.getOptions().setCssEnabled(false);//if you don't need css
webClient.getOptions().setJavaScriptEnabled(false);//if you don't need js
HtmlPage page = webClient.getPage("http://XXX.xxx.xx");
...

In my own test, this is 8 times faster than the default options.(Note that this could be webpage-dependent)

You should use findElements to find the list of WebElements. See API doc here

findElement returns single WebElement whereas findElements is plural and should be the expected one in this case.

List<WebElement> fields = driver.findElements(By.xpath("//input[@type='text']"));
System.out.println(fields.size());

Several paths can be combined with | separator, which effectively works as a logical OR.

@FindBy(xpath = "somexpath1 | somexpath2")

I don't think barak manos's answer has fully explained it.

Imagine we have few elements as the followings:

1. <div class="value test"></div>
2. <div class="value test "></div>
3. <div class="first value test last"></div>
4. <div class="test value"></div>

How XPath matches

• Match only 1 (exact match), barak's answer

  driver.findElement(By.xpath("//div[@class='value test']"));
  

• Match 1, 2 and 3 (match class contains value test, class order matters)

  driver.findElement(By.xpath("//div[contains(@class, 'value test')]"));
  

• Match 1, 2, 3 and 4 (as long as elements have class value and test)

  driver.findElement(By.xpath("//div[contains(@class, 'value') and contains(@class, 'test')]"));
  

Also, in cases like this, Css Selector is always in favor of XPath (fast, concise, native).

• Match 1

  driver.findElement(By.cssSelector("div[class='value test']"));
  

• Match 1, 2 and 3

  driver.findElement(By.cssSelector("div[class*='value test']"));
  

• Match 1, 2, 3 and 4

  driver.findElement(By.cssSelector("div.value.test"));
  

You can enable JavaScript by doing either

• new HtmlUnitDriver(true);
• driver.setJavascriptEnabled(true);

What you need to do is to wait until the JavaScript is executed after get(url).

You can use Thread.sleep() method for adding some delay.

HtmlUnitDriver driver = new HtmlUnitDriver(BrowserVersion.FIREFOX_3_6);
driver.setJavascriptEnabled(true);
driver.get(url);

Thread.sleep(100);

runTest();

Update

As @Corey indicated in the comments, it could be nicer to use Explicit and Implicit Waits instead of Thread.sleep(). As I don't use them these days, I cannot confirm, though. It would be great if someone test them and update this answer.

You don't have your XPath syntax right. You need quotes round the text attribute values you're matching against. Try:

d.findElement(By.xpath("//select[@id='category']/option[@id='cat2']")).click();

You can test this with javascriptExecutor:

Vertical scrollbar:

boolean scrollBarPresent = ((JavascriptExecutor)driver).executeScript("return document.documentElement.scrollHeight>document.documentElement.clientHeight;");

Horizontal scrollbar:

boolean scrollBarPresent = ((JavascriptExecutor)driver).executeScript("return document.documentElement.scrollWidth>document.documentElement.clientWidth;");
