Selenium WebDriver FirefoxBinary#startProfile - java

What is the point of the method FirefoxBinary#startProfile?
How would one control a browser opened using the above method?
FirefoxBinary binary = new FirefoxBinary(new File("path\\to\\binary.exe"));
String profilePath = "path\\to\\profile";
FirefoxProfile profile = new FirefoxProfile(new File(profilePath));
binary.startProfile(profile, profilePath, "");
//A browser opens at this point, but how do I send it commands or attach
//it to a WebDriver?

The purpose of the method is to do exactly what it does: start an instance of Firefox using the specified profile. WebDriver makes a copy of the profile in the temp directory and adds the WebDriver Firefox extension into this copy of the profile. Th startProfile method launches Firefox, making sure to clean up the profile so that it's usable by the new instance. If you know what port the browser extension that gets added to the profile is listening on, you could connect to it and control the browser using the WebDriver JSON wire protocol commands.
However, unless you really know what you're doing, this is the complicated way to do it. You're far better off calling the FirefoxDriver constructor, passing in the FirefoxBinary object, and letting the internals of the constructor call the startProfile method for you.

Set capability on already running selenium webdriver

In selenium test step (like a button click) i want to prevent the selenium waiting for page finish loading. I cant throw the load Exception because then i cant work with the page anymore.
Its possible to do a simmilar thing like this:
DesiredCapabilities dr = DesiredCapabilities.chrome();
dr.setCapability("pageLoadStrategy", "none");
WebDriver driver = new RemoteWebDriver(new URL("...."), dr);
What I want is like "dr.setCapability("pageLoadStrategy", "none");" but just for one specifique step.
Does anyone know a way to do this?
Capabilities are no longer editable once the browser is launched.
One way to temporary disable the waiting is to implement your own get with a script injection.
Something like this:
//
// loads the page and stops the loading without exception after 2 sec if
// the page is still loading.
//
load(driver, "https://httpbin.org/delay/10", 2000);
public static void load(WebDriver driver, String url, int timeout) {
((JavascriptExecutor)driver).executeScript(
"var url = arguments[0], timeout = arguments[1];"
"window.setTimeout(function(){window.location.href = url}, 1);" +
"var timer = window.setTimeout(window.stop, timeout);" +
"window.onload = function(){window.clearTimeout(timer)}; "
, url, timeout);
}
As of the current implementation of Selenium once we configure the WebDriver instance with our intended configuration through DesiredCapabilities class and initialize the WebDriver session to open a Browser, we cannot change the capabilities runtime.
It is worth to mention, somehow if you are able to retrieve the runtime capabilities still you won't be able to change them back.
So, in-order to make a change in the pageLoadStrategy you have to initiate a new WebDriver session.
Here is #JimEvans clear and concise answer (as of Oct 24 '13 at 13:02) related to proxy settings capability:
When you set a proxy for any given driver, it is set only at the time WebDriver session is created; it cannot be changed at runtime. Even if you get the capabilities of the created session, you won't be able to change it. So the answer is, no, you must start a new session if you want to use different proxy settings.

Using Selenium on https web application that runs over vpn

First of all, I need to state that I am total beginner with Selenium.
I am trying to test an application in firefox browser using Selenium. Due to security issues the application works only over vpn.
My problem occurs with the following steps; I create the webdriver and navigate to the start (login) page of application. I get an "Authorization request" popup. If I cancel the popup, then I get to a page that states "Connection is not secure" (it's https address). After I get passed that, I lose the part where Selenium program should populate username and password and it just stays on the login page.
My question, is there a way to start Selenium testing on an application so that it is already opened and prepared (ie logged in) in browser? I am not happy that username and password are hard-coded in Selenium code.
If that is not possible, how do I skip that authorization popup and problem with non-secure connection? How do I populate username and password in safest way?
Thanks!
public static void main(String[] args) {
System.setProperty("webdriver.gecko.driver", "C:\\Selenium-java-3.0.1\\geckodriver.exe");
// I tried also with this code bellow in comment, but it did not work, it did not even get to login page
//WebDriverWait wait = new WebDriverWait(driver, 10);
//Alert alert = wait.until(ExpectedConditions.alertIsPresent());
//alert.authenticateUsing(new UserAndPassword("cfadmin", "20lipim18"));
driver.get("https://Application_login_page.com");
driver.findElement(By.xpath(".//*[#id='login']")).click();
driver.findElement(By.xpath("[#id='login']")).sendKeys("Username");
}
if it's possible, is there a way to start Selenium testing on application that is already opened and prepared (logged) in browser?
Try using firefox profile. Since selenium open fresh instance of browser by default. You can use your own firefox frofile.
This is a code to implement a profile, which can be embedded in the selenium code.
ProfilesIni profile = new ProfilesIni();
// this will create an object for the Firefox profile
FirefoxProfile myprofile = profile.getProfile("default");
// this will Initialize the Firefox driver
WebDriver driver = new FirefoxDriver(myprofile)
It will also maintain the session means you are already login to the application in firefox(default profile). Then if you execute the script, you will see that you are already logged in to the application.
There is no way to open already authorised page, you have to have to pass username and password through selenium script.
You may use below code to do the authentication
WebDriverWait wait = new WebDriverWait(driver, 10);
Alert alert = wait.until(ExpectedConditions.alertIsPresent());
alert.authenticateUsing(new UserAndPassword(username, password));

PhantomJS slower than ChromeDriver, using Selenium

I'm trying to use PhantomJS 2.0/GhostDriver instead the ChromeDriver, since I have read I could speed up my UI tests.
This is the test code I'm running, as part of a Junit test:
#Override
public void runTestCase() throws Exception {
long startTime = System.currentTimeMillis();
// log in as admin
Login.loginAs("admin", "password");
System.out.println(System.currentTimeMillis() - startTime);
}
The loginAs function fills in the text fields for the username and password, then click on the submit button and finally moves in the home section of the new returned page.
Now, I'm running once a time this simple test using both Phantomjs and ChromeDriver as driver for Selenium in Java (v2.45).
They are initialized as follow:
ChromeDriver
System.setProperty("webdriver.chrome.logfile", workingDirectory + "\\chromedriver.log");
service = new ChromeDriverService.Builder().usingDriverExecutable(new File(workingDirectory + "\\chromedriver.exe")).build();
capabilities = DesiredCapabilities.chrome();
options = new ChromeOptions();
options.addArguments("--allow-file-access-from-files");
options.addArguments("--verbose");
capabilities.setVersion("");
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
driver = new ChromeDriver(service, capabilities);
PhantomJS
System.setProperty("phantomjs.binary.path", workingDirectory + "\\phantomjs.exe");
cliArgsCap = new ArrayList<String>();
capabilities = DesiredCapabilities.phantomjs();
cliArgsCap.add("--web-security=false");
cliArgsCap.add("--ssl-protocol=any");
cliArgsCap.add("--ignore-ssl-errors=true");
cliArgsCap.add("--webdriver-loglevel=INFO");
cliArgsCap.add("--load-images=false");
capabilities.setCapability(CapabilityType.SUPPORTS_FINDING_BY_CSS, true);
capabilities.setCapability(CapabilityType.TAKES_SCREENSHOT, true);
capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_CLI_ARGS, cliArgsCap);
driver = new PhantomJSDriver(capabilities);
I'm running my test on a 64bit Windows 7 machine. So, having a look the time took by the test, I always note that ChromeDriver is faster than PhantomJS. Always. For instance, if the test with ChromeDriver takes about 3-4 seconds, the same with PhantomJS takes about 5-6 seconds.
Has anyone experienced with this issue? Or could anyone give me any reason for that? Am I setting something wrong?
Furthermore, if you need more details, let me know.
I have found that this setting uses a lot of memory that seems to keep growing:
cliArgsCap.add("--load-images=false");
But when I use this setting the memory usage is stable:
cliArgsCap.add("--load-images=true");
"PhantomJS is a headless WebKit scriptable with a JavaScript API" as it's explained on the main page of the project.
Google split from WebKit to create Blink to use it in Chrome.
What are the main differences between them - unfortunately I'm not the expert here.
I run one of my really long scenarios both on Chrome and PhantomJS and to my surprise the difference was pretty significant:
PhantomJS - 583.251 s
Chrome - 448.384 s
Using PhantomJS doesn't bring performance benefits in my case but running tests headless does. I can use machine without graphical desktop and save computing power for some additional threads.
The slowest aspect of a web page is the downloading of html, JavaScript, css, images, etc and making AJAX request.
To anybody who says Headless is faster, how can headless address any of these?

Selenium Webdriver Continuing After Site from get() Prompts for Cert

I'm writing a Java app in which I'm doing a simple driver.get(url) in which the url will prompt for a cert selection. I want to try and automate the cert selection process in Firefox 33 using the AutoIt jar, but I can't even get my Java program to continue after it executes this get, since the site is in an indefinite state of loading until a cert is selected, so the execution indefinitely stays on the get itself. Is there any way around this?
I found a similar question: Make Selenium Webdriver Stop Loading the page if the desired element is already loaded?
Ths solution given in the above link is to change the firefox settings in case the webpage is taking too long to load.
FirefoxBinary firefox = new FirefoxBinary(new File("/path/to/firefox.exe"));
FirefoxProfile customProfile = new FirefoxProfile();
customProfile.setPreference("network.http.connection-timeout", 10);
customProfile.setPreference("network.http.connection-retry-timeout", 10);
driver = new FirefoxDriver(firefox, customProfile);

prevent external content to be loaded in selenium webdriver test

The question:
Is is possible to tell a browser that is controlled by selenium webdriver to not load any content from external sources, or alternatively, not load resources from a given list of domains?
Backround:
I have a webpage against which I write a java based test script with selenium webdriver - I can't change the page, I just have to write the tests. There are issues with some external content that the site loads from another domain. The external stuff is some javascript code that is actually not needed for my tests, but that the page in question includes. Now the problem. Sometimes the external sources are super slow, preventing the the webdriver to load the page within the given page load timeout (20 sec). My tests actually would run fine, because the page is in fact loaded - all html is there, all internal scripts are loaded and would work.
Random thoughts about this:
There are extensions for different browsers that would do what I ask, but I need to run my tests with several browsers, namely chrome, firefox and phantomjs. And there is no such thing like phantomjs extensions. I need a solution that is purely based on the webdriver technology if possible. I am willing to program a separate solution for each browser, though.
I appreciate any idea about how to address this.
Solution is to use proxy. Webdriver integrates very well with browsermob proxy: http://bmp.lightbody.net/
private WebDriver initializeDriver() throws Exception {
// Start the server and get the selenium proxy object
ProxyServer server = new ProxyServer(proxy_port); // package net.lightbody.bmp.proxy
server.start();
server.setCaptureHeaders(true);
// Blacklist google analytics
server.blacklistRequests("https?://.*\\.google-analytics\\.com/.*", 410);
// Or whitelist what you need
server.whitelistRequests("https?://*.*.yoursite.com/.*. https://*.*.someOtherYourSite.*".split(","), 200);
Proxy proxy = server.seleniumProxy(); // Proxy is package org.openqa.selenium.Proxy
// configure it as a desired capability
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.PROXY, proxy);
// start the driver ;
Webdriver driver = new FirefoxDriver(capabilities);
return driver;
}
EDIT:
people are often asking for http status codes, you can easily retrive them using the proxy. Code can be something like this:
// create a new har with given label
public void setHar(String label) {
server.newHar(label);
}
public void getHar() throws IOException {
// FIXME : What should be done with the this data?
Har har = server.getHar();
if (har == null) return;
File harFile = new File("C:\\localdev\\bla.har");
har.writeTo(harFile);
for (HarEntry entry : har.getLog().getEntries()) {
// Check for any 4XX and 5XX HTTP status codes
if ((String.valueOf(entry.getResponse().getStatus()).startsWith("4"))
|| (String.valueOf(entry.getResponse().getStatus()).startsWith("5"))) {
log.warn(String.format("%s %d %s", entry.getRequest().getUrl(), entry.getResponse().getStatus(),
entry.getResponse().getStatusText()));
//throw new UnsupportedOperationException("Not implemented");
}
}
}
You can chain the proxy, there isn't much documentation out there about doing so:
http://www.nerdnuts.com/2014/10/browsermob-behind-a-corporate-proxy/
We were able to use browsermob behind a corporate proxy using the following code:
// start the proxy
server = new ProxyServer(9090);
server.start();
server.setCaptureContent(true);
server.setCaptureHeaders(true);
server.addHeader(“accept-encoding”, “”);//turn off gzip
// Configure proxy server to use our network proxy
server.setLocalHost(InetAddress.getByName(“127.0.0.1″));
/**
* THIS IS THE MAJICK!
**/
HashMap<String, String> options = new HashMap<String, String>();
options.put(“httpProxy”, “172.20.4.115:8080″);
server.setOptions(options);
server.autoBasicAuthorization(“172.20.4.115″, “username”, “password”);
// get the Selenium proxy object
Proxy proxy = server.seleniumProxy();
DesiredCapabilities capabilities = DesiredCapabilities.phantomjs();
capabilities.setCapability(CapabilityType.PROXY, proxy);
