// Create a new instance of the Firefox driver and open Google webpage
WebDriver driver = new FirefoxDriver();
driver.get(“http://www.google.com”);
// Find the text input element by its name, enter some text and submit the form
WebElement element = driver.findElement(By.name(“q”));
element.sendKeys(“Cheese!”);
element.submit();
// Wait for the page to load
(new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver d) {
return d.getTitle().toLowerCase().startsWith(“cheese!”);
}
});
System.out.println(“Page title is: ” + driver.getTitle());
// Close the browser
driver.quit();
What can I do with it?
What can I do with it?
โ Manage browser (open/close, profiles);
โ navigate (url, history);
โ work with windows, tabs, popups;
โ query DOM (XPath, CSS selector, by ID);
โ make inputs (keyboard, mouse);
โ exec JavaScript;
โ make screenshots.
Selenium limitations.
โ Dialog boxes (file download);
โ Flash elements;
โ Java applets.
Who uses it?
Google, Microsoft, IBM, Mozilla, LinkedIn.
When should I use Selenium?
โ Parsing of dynamic websites (lots of JavaScript);
โ close to a user experience;
โ specific automation;
โ rendering matters (graphics);
โ .. catching yourself doing a new browser.
Why exactly the Selenium?
โ Few alternatives: watir.com, sahipro.com, watin.org;
โ open source;
โ support: OS, languages, browsers;
โ setting the standards (W3C, 2017);
โ evolving (Selenium 4 roadmap);
โ integration (Jenkins, Visual Studio);
โ Selenium Grid;
โ docs and examples.
