Selenide is a library built on Selenium WebDriver that makes UI tests faster and more stable. It simplifies common tasks like waiting for elements, making assertions, uploading and downloading files, taking screenshots, and managing test infrastructure. Selenide shortens locator syntax and adds convenience methods like uploading files from the classpath and attaching screenshots to test reports. It also provides a configuration class to customize browser settings and timeouts.

1. Selenide. Пишем тесты быстро и
стабильно.
Сергей Брит

2. Что такое Selenide
•Библиотека (JVM)
•Построена на базе Selenium Webdriver
•Изначально для быстрых UI тестов
•Простой и без мусора

3. Проблемы UI тестов
•Ожидания
•Проверки
•Upload/download
•Репортинг(скриншотинг)
•Инфрструктура/архитектура

4. Начало
<dependency>
<groupId>com.codeborne</groupId>
<artifactId>selenide</artifactId>
<version>LATEST</version>
</dependency>

5. WebElements / SelenideElement
Selenium Webdriver Selenide
driver.findElementBy(locator) $(cssLocator)
By.id(locator), By.xpath(locator),
By.ByLinkText(locator)
withText(locator), byText, byTitle, byXpath,
byCssSelector
driver.findElementBy(locator).sendKeys(string) $(cssLocator).setValue(string)
1. WebElement.clear()
2. WebElement.sendKeys(text)
3. Trigger change event

6. WebElements / SelenideElement
Selenuim Selenide
Actions actions = new Actions(driver);
actions.sendKeys(driver
.findElement(By.xpath(locator)), Keys.ENTER);
$(cssLocator).pressEnter()
$(cssLocator).pressTab()
driver.findElementBy(locator). getText(string) $(cssLocator).text()

7. Elements Collections
Selenium Webdriver Selenide
driver.getElements(locator) $$(locator)
-- filter(condition), exclude(), find()

8. Conditions
Selenium Selenide
класс ExpectedConditions класс Conditions
Используеться в Waiter Используется в should, is
new WebdriverWait(driver).until(…) $(locator).shouldBe(condition) или
$(locator).shouldBe(condition)
isDisplayed()
isSelected()
…
$(locator).is(condition)
e.g. is(visible), is(exists), is(hidden)

9. Configuration
Selenium Selenide
• DesireCapabilities
• Options
• Preferencies
Configuration class
+
• DesireCapabilities
• Options
• Preferencies
e.g.
Configuration.timeout = 10000;
Configuration.baseUrl = "http://the-internet.herokuapp.com";
Configuration.startMaximized = true;

10. Upload file
Selenium
driver.findElement(By.id("uploadfile_0"));
uploadElement.sendKeys("C:newhtml.html");
driver.findElement(By.id("terms")).click();
Selenide
File fileToUpload = $(locator).uploadFromClasspath(“file”);

11. Download file Selenium
WebDriver driver;
File folder;
folder = new File(UUID.randomUUID().toString());
folder.mkdir();
FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("browser.download.dir", folder.getAbsolutePath());
profile.setPreference("browser.download.folderList", 2);
profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "image/jpeg,
application/pdf, application/octet-stream");
profile.setPreference("pdfjs.disabled", true);
driver = new FirefoxDriver(profile);

12. Download file Selenium
@Test
public void download() throws Exception {
driver.get("http://the-internet.herokuapp.com/download");
driver.findElement(By.cssSelector(".example a")).click();
// Wait 2 seconds to download file
Thread.sleep(2000);
File[] listOfFiles = folder.listFiles();
// Make sure the directory is not empty
assertThat(listOfFiles.length, is(not(0)));
for (File file : listOfFiles) {
// Make sure the downloaded file(s) is(are) not empty
assertThat(file.length(), is(not((long) 0)));
}
}

13. Download file Selenide
File downloadedFile = $("locator").download();

14. Selenium screenshots
File scrFile = ((TakesScreenshot)driver)
.getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(scrFile,
new File("c:tmpscreenshot.png"));

15. Screenshot Selenide
@Attachment(type = "image/png", value = "{templateName}")
public byte[] saveScreenshot(ITestResult iTestResult) throws
IOException {
String file = Selenide.screenshot(iTestResult.getTestName());
return FileUtils.readFileToByteArray(new File(file));
}
