Capturing Network calls:
To capture the network calls while loading a page, we need to use java script executor, ]the following example may helps:
ChromeOptions options = new ChromeOptions();
options.addArguments("disable-info");
options.addArguments("start-maximized");
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
driver = new ChromeDriver(capabilities);
driver.get(url);
//switch to Browser Functions tab for code implementation
String netData = ((JavascriptExecutor) driver).executeScript(scriptToExecute).toString();
BrowserFunctions.waitUntilPageLoads(driver);
String scriptToExecute = "var performance = window.performance || window.mozPerformance || window.msPerformance || window.webkitPerformance || {}; var network = performance.getEntries() || {};
return network;";
System.out.println(netData);
Note: The out put in json format.
Capture Network performance:
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());
}
