I tried to use (jp#gc - HtmlUnit Driver Config) to create a headless browser test using jmeter, but I get this error
Response message: com.gargoylesoftware.htmlunit.ScriptException: ReferenceError: "getComputedStyle" is not defined.
I read online and it suggest that jp#gc - HtmlUnit Driver Config doesn't support javascript. Is there a way I can fix this via jmeter? or is there any other option to do headless browser testing. I have linux server as load injector
Update:
I have a webdriver sampler to open google page
WDS.sampleResult.sampleStart() WDS.browser.get('http://google.com')
WDS.sampleResult.sampleEnd()
and have downloaded Phanton JS, but when I run it it doesn't show anything on the report. Should I add any other config?
HtmlUnit do not support very well JS.
I done many tests and used each one and i can say that PHANTOMJS is the best one with good support of all JS/CSS... have a beautiful renderer to have nice screenshots.
by code you can use it like this (you can download it from here http://phantomjs.org/download.html (phantomjs-1.9.8 is very stable)):
Capabilities caps = new DesiredCapabilities();
((DesiredCapabilities) caps).setJavascriptEnabled(true);
((DesiredCapabilities) caps).setCapability("takesScreenshot", true);
((DesiredCapabilities) caps).setCapability(
PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,
"your custom path\\phantomjs.exe"
);
WebDriver driver = new PhantomJSDriver(caps);
If you want to do that via JMeter GUI, you need to add before your Logic Controller an element JSR223 Sampler JSR223_Sampler
and inside the script panel :
org.openqa.selenium.Capabilities caps = new org.openqa.selenium.remote.DesiredCapabilities();
((org.openqa.selenium.remote.DesiredCapabilities) caps).setJavascriptEnabled(true);
((org.openqa.selenium.remote.DesiredCapabilities) caps).setCapability("takesScreenshot", true);
((org.openqa.selenium.remote.DesiredCapabilities) caps).setCapability(
org.openqa.selenium.phantomjs.PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,
"your custom path\\phantomjs.exe");
org.openqa.selenium.WebDriver driver = new org.openqa.selenium.phantomjs.PhantomJSDriver(caps);
org.apache.jmeter.threads.JMeterContextService.getContext().getCurrentSampler().getThreadContext()
.getVariables().putObject(com.googlecode.jmeter.plugins.webdriver.config.WebDriverConfig.BROWSER, driver);
Do not hesitate if you need more informations.

I need to get the http request URL when a button is clicked in a webpage programatically.
I am using selenium to trace the button and I am performing click on the button. on click of the button it makes a http request and the same can be traced in the network tab of the browser.
How can i get the request URL programatically once I trigger the button click using selenium.
Any other tools or libraries that I can use to achieve the same functions is also ok for me. I just need to be able to get the URL after button click programatically. This is a dynamic URL which changes periodically and the objective is to automate the download process through code.
Thanks in advance for any help!
You can use JavaScript executor to get network data. Please refer https://stackoverflow.com/a/45859018/5966329
get request/response data from there.
DesiredCapabilities d = DesiredCapabilities.chrome();
LoggingPreferences logPrefs = new LoggingPreferences();
logPrefs.enable(LogType.PERFORMANCE, Level.ALL);
d.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);
WebDriver driver = new ChromeDriver(d);
driver.get("https://www.google.co.in/");
driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
LogEntries les = driver.manage().logs().get(LogType.PERFORMANCE);
for (LogEntry le : les) {
System.out.println(le.getMessage());
}
Python Equivalent:
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import
DesiredCapabilities
caps = DesiredCapabilities.CHROME
caps['goog:loggingPrefs'] = {'performance': 'ALL'}
driver = webdriver.Chrome(desired_capabilities=caps)
driver.get('https://stackoverflow.com')
for entry in driver.get_log('performance'):
print(entry)
Please refer thread for more info python
I am using jp#gc - Firefox Driver Config plugin to hit some URL and assert some element in UI.
But I am not able to launch firefox driver as I cant see an option to enable to run firefox as a headless browser .
JP#GC - WebDriver Sampler:
import org.openqa.selenium.By;
import org.openqa.selenium.support.ui.ExpectedConditions; import org.openqa.selenium.support.ui.WebDriverWait
def wait = new WebDriverWait(WDS.browser,5000);
WDS.sampleResult.sampleStart(); WDS.browser.get('https://google.com/'); wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(".//input[#name='q']"))); WDS.sampleResult.sampleEnd()
How about checking Headless box in the jp#gc - Firefox Driver Config?
Going forward be aware that you can always bypass any JMeter limitation by implementing whatever you want/need using JSR223 Test Elements and Groovy language, example code to kick off a headless Firefox would be something like:
System.setProperty('webdriver.gecko.driver','c:/apps/webdriver/geckodriver.exe')
def options = new org.openqa.selenium.firefox.FirefoxOptions()
options.addArguments('--headless')
def driver = new org.openqa.selenium.firefox.FirefoxDriver(options)
driver.get('http://example.com')
log.info('Current page title: ' + driver.getTitle())
driver.quit()

I am looking for a method to download automatically a file from a website.
Currently the process is really manual and heavy.
I go on a webpage, I enter my pass and login.
It opens a pop up, where I have to click a download button to save a .zip file.
Do you have any advice on how I could automate this task ?
I am on windows 7, and I can use mainly MS dos batch, or python. But I am open to other ideas.
You can use selenium web driver to automate the downloading. You can use below snippet for browser download preferences in java.
FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("browser.download.folderList", 2);
profile.setPreference("browser.download.manager.showWhenStarting", false);
profile.setPreference("browser.download.dir", "C:\\downloads");
profile.setPreference("browser.helperApps.neverAsk.openFile","text/csv,application/x-msexcel,application/excel,application/x-excel,application/vnd.ms-excel,text/html,text/plain,application/msword,application/xml");
To handle the popup using this class when popup comes.
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_DOWN);
robot.keyRelease(KeyEvent.VK_DOWN);
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
You'll want to take a look at requests (to fetch the html and the file), Beautifulsoup (to parse the html and find the links)
requests has built in auth: http://docs.python-requests.org/en/latest/
Beautifulsoup is quite easy to use: http://www.crummy.com/software/BeautifulSoup/bs4/doc/
Pseudocode: use request to download the sites html and auth. Go through the links by parsing. If a link meets the criteria -> save in a list, else continue. When all the links have been scrapped, go through them and download the file using requests (req = requests.get('url_to_file_here', auth={'username','password'}), if req.status_code in [200], file = req.text
If you can post the link of the site you want to download from, maybe we can do more.
I need to control Firefox browser via webdriver. Note, I'm not trying to control page elements (i.e. find element, click, get text, etc); rather I need access to Firefox's profiler and force gc (i.e. I need firefox's Chrome Authority and sdk). For context, I'm creating a micro benchmark framework, not running a normal webdriver test.
Obviously raw webdriver won't work, so what I've been trying to do is
1) Create a firefox extension/add-on that does what I need: i.e.
var customActions = function() {
console.log('calling customActions.')
// I need to access chrome authority:
var {Cc,Ci,Cu} = require("chrome");
Cc["#mozilla.org/tools/profiler;1"].getService(Ci.nsIProfiler);
Cu.forceGC();
var file = require('sdk/io/file');
// And do some writes:
var textWriter = file.open('a/local/path.txt', 'w');
textWriter.write('sample data');
textWriter.close();
console.log('called customActions.')
};
2) Expose my customActions function to a page:
var mod = require("sdk/page-mod");
var data = require("sdk/self").data;
mod.PageMod({
include: ['*'],
contentScriptFile: data.url("myscript.js"),
onAttach: function(worker) {
worker.port.on('callCustomActions', function() {
customActions();
});
}
});
and in myscript.js:
exportFunction(function() {
self.port.emit('callCustomActions');
}, unsafeWindow, {defineAs: "callCustomActions"});
3) Load the xpi during my webdriver test, and call out to global function callCustomActions
So two questions about this process.
1) This entire process is very roundabout. Is there a better practice for talking to a firefox extension via webdriver?
2) My current solution isn't working well. If I run my extension via cfx run directly (without webdriver) it works as expected. However, neither the sdk nor chrome authority do anything when running via webdriver.
By the way, I know my function is being called because the log line "calling customActions." and "called customActions." both do print.
Maybe there are some firefox preferences that I need to set but haven't?
It may be that you do not need the add-on at all. Mozilla uses Marionette for test automation of Firefox OS amongst other things:
Marionette is an automation driver for Mozilla's Gecko engine. It can
remotely control either the UI or the internal JavaScript of a Gecko
platform, such as Firefox or Firefox OS. It can control both the
chrome (i.e. menus and functions) or the content (the webpage loaded
inside the browsing context), giving a high level of control and
ability to replicate user actions. In addition to performing actions
on the browser, Marionette can also read the properties and attributes
of the DOM.
If this sounds similar to Selenium/WebDriver then you're correct!
Marionette shares much of the same ethos and API as
Selenium/WebDriver, with additional commands to interact with Gecko's
chrome interface. Its goal is to replicate what Selenium does for web
content: to enable the tester to have the ability to send commands to
remotely control a user agent.
I want to use xvfb to open browser headless for my client-side performance test using jmeter. I am using selenium [Junit sampler] to run the test. How do I override display variable in jmeter so that it does not open browser.?
Option 1
If you're using Firefox you can utilize FirefoxBinary.setEnvironmentProperty() method
FirefoxBinary bin = new FirefoxBinary(new File("/opt/firefox28/firefox"));
bin.setEnvironmentProperty("DISPLAY",":1"); // or where you have Xvbf running
FirefoxDriver driver = new FirefoxDriver(bin,new FirefoxProfile());
Option 2
Consider switching to PhantomJS which is headless by design
Option 3
Consider switching to WebDriver Sampler's HTMLUnitDriver support which is also totally headless.
