Selenium Webdriver is an automated testing platform for web pages. It may not be the easiest or the most user-friendly, and it definitely requires a lot of coding, but it's the most powerful and works with any website. Even better, it "drives" a real web browser and simulates real clicks, so you're getting a real UI test, not just a URL test.
It's good stuff, but it's also arcane. That's why I'm putting together this handy cheat sheet. Expect it to change over time.
Note: Webdriver supports many languages; my syntax is all for java. Don't ask me why.
| TASK | CODE |
|---|---|
| Start a new web driver, set window size & position |
WebDriver driver = new FirefoxDriver(); |
| Make sure an element has loaded before you target it (implicit wait) |
WebElement uname = (new WebDriverWait(driver, 60))
.until(ExpectedConditions.presenceOfElementLocated(By.id("edit-name")));
uname.sendKeys(username);
|
| Make the script wait (explicit wait) | Thread.sleep(500); |
| Close the window when you're done | driver.quit(); |
| Take a screenshot |
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
try {
FileUtils.copyFile(scrFile, new File(screenshot + ".png"));
} catch (IOException e) {
// Auto-generated catch block
e.printStackTrace();
}
|
| Click on a web element | driver.findElement(By.linkText("EDIT")).click(); |
| Select from a dropdown menu | new Select(driver.findElement(By.id("edit-status"))).selectByVisibleText("No"); |
| Make sure something is selected | Assert.assertTrue(driver.findElement(By.id("edit-status-0")).isSelected()); |
| Make sure text is present on a page |
String body = driver.findElement(By.tagName("body")).getText();
Assert.assertTrue(body.contains(constant.targetuser));
|
| Send report to console | System.out.println("Turnover note found"); |
| Find an element using xpath | driver.findElement(By.xpath("//a[@class='username']")); |
