I want to check status code of these 3 sites: http://google.com, http://birgun.net, http://roche.com. But I need to only check with Selenium Java. I have no idea for checking status codes with Selenium. Can you help me for writing to code? I've checked How to get HTTP Response Code using Selenium WebDriver but I couldn't satisfy, couldn't understand it.
As it is stated in the question you refer it is not possible. Selenium works on UI level. You can apply browsermob-proxy that you can integrate your Selenium test with. In that proxy you can add filter that would check your responses for required status code.
Below is the "fishbone" for sch test.
#Test
public void statusCode(){
// ...
proxy.addResponseFilter((httpResponse, httpMessageContents, httpMessageInfo) -> {
if (httpMessageInfo.getOriginalUrl().equals(getCurrentUrl(driver))
&& !httpResponse.getStatus().equals(HttpResponseStatus.OK)){
// TODO: do smth;
}
});
// ...
}
private String getCurrentUrl(WebDriver driver){
return driver.getCurrentUrl();
}
Note that you need to narrow the requests scope that you're watching for status code of since proxy processes all the HTTP calls from your page including calls to resources and AJAX calls..
Here you can find example on how to check the page for not loaded images. This is very similar to your case. You can examine it in order to get the general idea of the approach and modify it so that it would meet your need.
I am trying to develop a Suite of classes for testing my websites functionality every night and I do this in Chrome, Firefox, Edge and IE. Because sometimes Selenium doesn't find an element I need something that e.g. takes a screenshot of the browser before giving out an error. I don't need a function for taking a screenshot I need something that triggers when Selenium can't continue.
Best regards,
MK
If I understand correct, you need to set up the trigger for your another system, which can react on Selenium test error.
In your test code you can use :
try {
// find element and test code
} catch (NoSuchElementException e) {
// set up the trigger code
}
To notify another system you can choose any system, which can provide notification mechanism.
In your case, you could use for example Redis with pub/sub.
So your reaction system will be a subscriber and test - provider of the event.
I need help for this thing that's driving me crazy.
I want to check the browser url in and endless loop, waiting a little (Thread.Sleep) between a loop and another, to not overload the CPU. Then, if the browser url is what I need, I want to add/change/remove an element through Javascript before the page is fully loaded, otherwise the person who uses this could see the change. (I don't need help for the javascript part)
But there's a problem: it seems that in Selenium Webdriver when I navigate to a page (with .get(), .navigate().to() or also directly from the client) the execution is forced to stop until the page is loaded.
I tried to set a "fake" timeout, but (at least in Chrome) when it catches the TimeoutException, the page stops loading. I know that in Firefox there's an option for unstable loading, but I don't want to use it because my program isn't only for Firefox.
public static void main(String[] args) throws InterruptedException {
System.setProperty("webdriver.chrome.driver", "chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.manage().timeouts().pageLoadTimeout(0, TimeUnit.MILLISECONDS); // Fake timeout
while (true) {
try {
// If the url (driver.getCurrentUrl()) is what I want, then execute javascript without needing that page is fully loaded
// ...
// ...
}
catch (TimeoutException e) {
// It ignores the Exception, but unfortunately the page stops loading.
}
Thread.sleep(500); // Then wait some time to not overload the cpu
}
}
I need to do this in Chrome, and if possible with Firefox and Internet Explorer. I'm programming in Java. Thanks in advance.
Selenium is designed to stop once the webpage is loaded into the browser so that it can proceed with execution.
In your case there are two options:
1) If the browser url will change automatically (ajax) at an arbitrary time, then just keep getting browser url until your condition satisfies.
while(currentURL.equals("Your Condition")){
currentURL = driver.getCurrentUrl();
Thread.sleep(2000);
}
2) If the browser needs to be refreshed use the refresh method in a loop until you get your desired url
while(currentURL.equals("Your Condition")){
driver.navigate().refresh();
currentURL =
Thread.sleep(2000);
}
As know, if user tried with driver.get("url");, selenium waits until page is loaded (may not be very long). so if you want to do some thing on navigate to URL without waiting total load time use below code instead of get or navigate
JavascriptExecutor js=(JavascriptExecutor)driver;
js.executeScript("window.open('http://seleniumtrainer.com/components/buttons/','_self');");
After this used
driver.findElement(By.id("button1")).click();
to click on button but i am getting no such element exception, so i am expecting its not waiting for page load. so times page loading very quick and click working fine.
i hope this will help you to figure it out your issue at start up. for loop i hope solution already provided.
Thanks
I'm using HtmlUnit 2.10 to click a link which triggers a JavaScript that redirects to another URL. JavaScript uses window.location to redirect. The result is not the same as if I open the page directly with the URL. The redirection page result looks as if the page is still loading, although it's not.
When looking at the requests sent it looks as if HtmlUnit requests the page and even send the ajax-requests FROM the page I'm trying to get redirected to, but does not show it. I've tried IO-writing "page.asXml()" into a .html file to get a preview of the page, and it contains almost nothing, as if it's still loading the new content. But, I've also tried waiting for up to 100 seconds for the page to load with
synchronized (page) {
page.wait(int x);
}
and it does not make any difference to the result.
I cannot give a reproducable script for this error since the page is run locally only at the moment.
Any thoughts as to what can be wrong?
Edit: I can add that this problem seemed to arrive with the upgrade to jQuery 1.8.1 from jQuery 1.7.0.
Still i do not see clearly the way how to resolve completely your problem, but I've got an assumption how to investigate your problem deeper(i.e. wheter you've been redirected properly or not):
localize 1 -2 elements on the page you want be redirected with cssSelector or xpath.
then after redirecting call fluentWait()
public WebElement fluentWait(final By locator){
Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
.withTimeout(30, TimeUnit.SECONDS)
.pollingEvery(5, TimeUnit.SECONDS)
.ignoring(NoSuchElementException.class);
WebElement foo = wait.until(
new Function<WebDriver, WebElement>() {
public WebElement apply(WebDriver driver) {
return driver.findElement(locator);
}
}
);
return foo; } ;
you can read about fluent wait here
If it returns web element on the page u've been redirected to. Otherwise it fails.
Hope this somehow helps you.
Make sure you have set the WebClient to have it's redirectEnabled field set to true. To do this, simply add this line before you execute the request...
webClient.setRedirectEnabled(true);
This will ensure redirects are followed by the HtmlUnit client.
Here are the docs for the method.
What is the difference between get() and navigate() methods?
Does any of this or maybe another method waits for page content to load?
What do I really need is something like Selenium 1.0's WaitForPageToLoad but for using via webdriver.
Any suggestions?
Navigating
The first thing you’ll want to do with WebDriver is navigate to a page. The normal way to do this is by calling get:
driver.get("http://www.google.com");
WebDriver will wait until the page has fully loaded (that is, the onload event has fired) before returning control to your test or script. It’s worth noting that if your page uses a lot of AJAX on load then WebDriver may not know when it has completely loaded. If you need to ensure such pages are fully loaded then you can use waits.
Navigation: History and Location
Earlier, we covered navigating to a page using the get command (driver.get("http://www.example.com")) As you’ve seen, WebDriver has a number of smaller, task-focused interfaces, and navigation is a useful task. Because loading a page is such a fundamental requirement, the method to do this lives on the main WebDriver interface, but it’s simply a synonym to:
driver.navigate().to("http://www.example.com");
To reiterate: navigate().to() and get() do exactly the same thing. One's just a lot easier to type than the other!
The navigate interface also exposes the ability to move backwards and forwards in your browser’s history:
driver.navigate().forward();
driver.navigate().back();
(Emphasis added)
They both seems to navigate to the given webpage and quoting #matt answer:
navigate().to() and get() do exactly the same thing.
Single-Page Applications are an exception to this.
The difference between these two methods comes not from their behavior, but from the behavior in the way the application works and how browser deal with it.
navigate().to() navigates to the page by changing the URL like doing forward/backward navigation.
Whereas, get() refreshes the page to changing the URL.
So, in cases where application domain changes, both the method behaves similarly. That is, page is refreshed in both the cases. But, in single-page applications, while navigate().to() do not refreshes the page, get() do.
Moreover, this is the reason browser history is getting lost when get() is used due to application being refreshed.

driver.get() : It's used to go to the particular website , But it doesn't maintain the browser History and cookies so , we can't use forward and backward button , if we click on that , page will not get schedule
driver.navigate() : it's used to go to the particular website , but it maintains the browser history and cookies, so we can use forward and backward button to navigate between the pages during the coding of Testcase
Not sure it applies here also but in the case of protractor when using navigate().to(...) the history is being kept but when using get() it is lost.
One of my test was failing because I was using get() 2 times in a row and then doing a navigate().back(). Because the history was lost, when going back it went to the about page and an error was thrown:
Error: Error while waiting for Protractor to sync with the page: {}
driver.get() is used to navigate particular URL(website) and wait till page load.
driver.navigate() is used to navigate to particular URL and does not wait to page load. It maintains browser history or cookies to navigate back or forward.
As per the javadoc for get(), it is the synonym for Navigate.to()
View javadoc screenshot below:
Javadoc for get() says it all -
Load a new web page in the current browser window. This is done using
an HTTP GET operation, and the method will block until the load is
complete. This will follow redirects issued either by the server or as
a meta-redirect from within the returned HTML. Should a meta-redirect
"rest" for any duration of time, it is best to wait until this timeout
is over, since should the underlying page change whilst your test is
executing the results of future calls against this interface will be
against the freshly loaded page. Synonym for
org.openqa.selenium.WebDriver.Navigation.to(String).
navigate().to() and get() will work same when you use for the first time. When you use it more than once then using navigate().to() you can come to the previous page at any time whereas you can do the same using get().
Conclusion: navigate().to() holds the entire history of the current window and get() just reload the page and hold any history.
For what it's worth, from my IE9 testing, it looks like there's a difference for URLs that contain a hashbang (a single page app, in my case):
http://www.example.com#page
The driver.get("http://www.example.com#anotherpage") method is handled by the browser as a fragment identifier and JavaScript variables are retained from the previous URL.
While, the navigate().to("http://www.example.com#anotherpage") method is handled by the browser as a address/location/URL bar input and JavaScript variables are not retained from the previous URL.
There are some differences between webdriver.get() and webdriver.navigate() method.
get()
As per the API Docs get() method in the WebDriver interface extends the SearchContext and is defined as:
/**
* Load a new web page in the current browser window. This is done using an HTTP POST operation,
* and the method will block until the load is complete.
* This will follow redirects issued either by the server or as a meta-redirect from within the
* returned HTML.
* Synonym for {#link org.openqa.selenium.WebDriver.Navigation#to(String)}.
*/
void get(String url);
Usage:
driver.get("https://www.google.com/");
navigate()
On the other hand, navigate() is the abstraction which allows the WebDriver instance i.e. the driver to access the browser's history as well as to navigate to a given URL. The methods along with the usage are as follows:
to(java.lang.String url): Load a new web page in the current browser window.
driver.navigate().to("https://www.google.com/");
to(java.net.URL url): Overloaded version of to(String) that makes it easy to pass in a URL.
refresh(): Refresh the current page.
driver.navigate().refresh();
back(): Move back a single "item" in the browser's history.
driver.navigate().back();
forward(): Move a single "item" forward in the browser's history.
driver.navigate().forward();
driver.get("url") and driver.navigate( ).to("url") both are same/synonymous.
to("url") internally calling get("url") method. Please find the below image for reference.
Either of them does not store history - this is the wrong information that is available on most of the blogs/websites.
Below, statements 1, 2, and 3, 4 will do the same things i.e land in the given URL.
statemnt 1: driver.get("http://www.google.com");
statemnt 2: driver.navigate( ).to("http://www.amazon.in");
statemnt 3: driver.get("http://www.google.com");
statemnt 4: driver.get("http://www.amazon.in");
Only navigate() can do different things i.e. moving back, forward, etc. But not the to("url") method.
Otherwise you prob want the get method:
Load a new web page in the current browser window. This is done using an
HTTP GET operation, and the method will block until the load is complete.
Navigate allows you to work with browser history as far as i understand it.
Both perform the same function but driver.get(); seems more popular.
driver.navigate().to(); is best used when you are already in the middle of a script and you want to redirect from current URL to a new one. For the sake of differentiating your codes, you can use driver.get();to launch the first URL after opening a browser instance, albeit both will work either way.
CASE-1
In the below code I navigated to 3 different URLs and when the execution comes to navigate command, it navigated back to facebook home page.
public class FirefoxInvoke {
#Test
public static void browserInvoke()
{
System.setProperty("webdriver.gecko.driver", "gecko-driver-path");
WebDriver driver=new FirefoxDriver();
System.out.println("Before"+driver.getTitle());
driver.get("http://www.google.com");
driver.get("http://www.facebook.com");
driver.get("http://www.india.com");
driver.navigate().back();
driver.quit();
}
public static void main(String[] args) {
// TODO Auto-generated method stub
browserInvoke();
}
}
CASE-2:
In below code, I have used navigate() instead of get(), but both the snippets(Case-1 and Case-2) are working exactly the same, just the case-2 execution time is less than of case-1
public class FirefoxInvoke {
#Test
public static void browserInvoke()
{
System.setProperty("webdriver.gecko.driver", "gecko-driver-path");
WebDriver driver=new FirefoxDriver();
System.out.println("Before"+driver.getTitle());
driver.navigate().to("http://www.google.com");
driver.navigate().to("http://www.facebook.com");
driver.navigate().to("http://www.india.com");
driver.navigate().back();
driver.quit();
}
public static void main(String[] args) {
// TODO Auto-generated method stub
browserInvoke();
}
}
So the main difference between get() and navigate() is, both are
performing the same task but with the use of navigate() you can move
back() or forward() in your session's history.
navigate() is faster than get() because navigate() does not wait for
the page to load fully or completely.
driver.get(url) and navigate.to(url) both are used to go to particular web page. The key difference is that
driver.get(url): It does not maintain the browser history and cookies and wait till page fully loaded.
driver.navigate.to(url):It is also used to go to particular web page.it maintain browser history and cookies and does not wait till page fully loaded and have navigation between the pages back, forward and refresh.
To get a better understanding on it, one must see the architecture of Selenium WebDriver.
Just visit https://github.com/SeleniumHQ/selenium/wiki/JsonWireProtocol
and search for "Navigate to a new URL." text. You will see both methods GET and POST.
Hence the conclusion given below:
driver.get() method internally sends Get request to Selenium Server Standalone. Whereas driver.navigate() method sends Post request to Selenium Server Standalone.
