WebDriverException: unknown error: cannot determine loading status from timeout: Timed out receiving message from renderer: 60 using Selenium and Java

Question

In my Java project I am using Selenium for web automation. I am using chromedriver v2.20 executable. First "ChromeDriverService" is initialised and that is used to create ChromeDriver like, "new ChromeDriver(service, capabilities);". Also I used BrowserMobProxy to capture all web requests. In my test I navigate to some URLs multiple times, after each navigation driver implicitly waits for few seconds, then polls result. But while Execution it gives me timeout Exception.

In my research I came across solutions which are not working for me:

1. Instead of implicitlyWait use Thread.sleep
2. Replace new RemoteWebDriver(service.getUrl(), capabilities); by new ChromeDriver(service, capabilities);
3. After new ChromeDriver(...), wait for 1 sec using Thread.sleep(1000);

Can anyone please tell me why this error occurs ? how to handle this ?

ShouldPostToServerTest.java:

@Test 
public void setTest() throws Exception {
    for (int i = 0; i < 3; i++) {
        nav();
        poll();
    }
}

private void nav() {
    String[] navTo = {"http://www.bestbuy.com","http://www.amazon.com"};
    for (int n = 0; n < 30 / navTo.length; n++) {
        for (String url : navTo) {
            chrome.navigateTo(url);
            chrome.waitFor(5000);
        }
    }
}

private void poll() {
    int pollInterval = 1000;
    int remaining = 120 * 1000;
    boolean found = false;
    while (remaining > 0) {
        if (found) // populateResult(), omitted for now.
            break;

        chrome.waitFor(pollInterval);
        remaining -= pollInterval;
    }
}

Chrome.java:

public void navigateTo(String url) {
    if (driver == null)
        return;

    driver.navigate().to(url); // TimeOut 
}
public void waitFor(long waitFor) {
    long start = System.currentTimeMillis();
    driver.manage().timeouts().implicitlyWait(waitFor, TimeUnit.MILLISECONDS);
    long duration = System.currentTimeMillis() - start;
    long remaining = waitFor - duration;
    if (remaining > 0) {
        try {
            Thread.sleep(remaining);
        } catch (InterruptedException e) {
            throw new RuntimeException(e);
        }
    }
}

Answer 1

Your code runs fine. Might be you using outdated chrome driver. I suggest to use latest exe of chrome driver.
