How to check URL for 404 using Selenium WebDriver?

Question

What is the most convenient way using Selenium WebDriver to check if an URL GET returns successfully (HTTP 200)?

In this particular case I\'m most interested in verifyin

Answer 1

You could use the getEval command to verify the value returned from the following JavaScript for each image on the page.

@Test
public void checkForBrokenImages() {
    selenium.open("http://www.example.com/");
    int imageCount = selenium.getXpathCount("//img").intValue();
    for (int i = 0; i < imageCount; i++) {
        String currentImage = "this.browserbot.getUserWindow().document.images[" + i + "]";
        assertEquals(selenium.getEval("(!" + currentImage + ".complete) ? false : !(typeof " + currentImage + ".naturalWidth != \"undefined\" && " + currentImage + ".naturalWidth == 0);"), "true", "Broken image: " + selenium.getEval(currentImage + ".src"));
    }
}
