How to automate with “ExpectedConditions” in Selenium WebDriver

Return type for “ExpectedConditions.xxxx()” is generally falls under following categories:

Alert
Boolean
WebElement
List
WebDriver
Object

Following code snippet demonstrates usage and validation based on return type. (ExpectedCondition testing with Selenium). We can add necessary asserts based on test automation requirements

import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.Select;
import org.openqa.selenium.support.ui.WebDriverWait;

public class ExpectedConditionsExamples {

public static void main(String[] args) throws InterruptedException {
WebDriver driver = new FirefoxDriver();
WebDriverWait wait = new WebDriverWait(driver, 10);
String URL = “http://www.vpl.ca/”;
driver.get(URL);

Boolean isTitleCorrect = wait.until(ExpectedConditions.titleContains(“Public”));
System.out.println(“titleContains results” + isTitleCorrect);

Boolean titleIs = wait.until(ExpectedConditions.titleIs(“Vancouver Public Library |”));
System.out.println(“Wait completed for title to be \”Vancouver Public Library |\”” + titleIs);

Boolean urlContains = wait.until(ExpectedConditions.urlContains(“vpl”));
System.out.println(“urlContains results” + urlContains);

Boolean urlToBe = wait.until(ExpectedConditions.urlToBe(“http://www.vpl.ca/”));
System.out.println(“urlToBe results” + urlToBe);

String regex = “\\b(https?|ftp|file)://[-a-zA-Z0-9+&@#/%?=~_|!:,.;]*[-a-zA-Z0-9+&@#/%=~_|]”;
Boolean urlMatches = wait.until(ExpectedConditions.urlMatches(regex));
System.out.println(“urlMatches results” + urlToBe);

// ExpectedConditions.elementToBeSelected
WebElement searchDDwn = driver.findElement(By.xpath(“.//*[@id=’edit-source’]”));
Select dropdown = new Select(searchDDwn);
dropdown.selectByValue(“Website”);
WebElement selected = dropdown.getFirstSelectedOption();
boolean elementToBeSelected = wait.until(ExpectedConditions.elementToBeSelected(selected));
System.out.println(“elementToBeSelected results” + elementToBeSelected);

// ExpectedConditions.invisibilityOfElementLocated
By searchDDwn1 = By.xpath(“.//*[@id=’edit-source1′]”);
boolean invisibilityOfElementLocated = wait.until(ExpectedConditions.invisibilityOfElementLocated(searchDDwn1));
System.out.println(“invisibilityOfElementLocated results” + invisibilityOfElementLocated);

// ExpectedConditions.invisibilityOfElementWithText
By searchDDwn2 = By.xpath(“.//*[text()=’edit-source1′]”);
boolean invisibilityOfElementWithText = wait
.until(ExpectedConditions.invisibilityOfElementWithText(searchDDwn2, “hello”));
System.out.println(“invisibilityOfElementWithText results” + invisibilityOfElementWithText);

// ExpectedConditions.stalenessOf
driver.navigate().refresh();
By searchDDwn3 = By.xpath(“.//*[text()=’edit-source1′]”);
boolean stalenessOf = wait.until(ExpectedConditions.invisibilityOfElementWithText(searchDDwn2, “hello”));
System.out.println(“stalenessOf results” + stalenessOf);

// ExpectedConditions.textToBePresentInElementLocated
By searchBoxId = By.id(“edit-search”);
WebElement searchBox = wait.until(ExpectedConditions.elementToBeClickable(searchBoxId));
searchBox.sendKeys(“java”);

boolean res = wait.until(ExpectedConditions.textToBePresentInElementLocated(searchBoxId, “java”));
System.out.println(“textToBePresentInElement results” + stalenessOf);

By searchButtonId = By.id(“edit-submit”);
WebElement searchButton = wait.until(ExpectedConditions.visibilityOfElementLocated(searchButtonId));
searchButton.click();

Thread.sleep(2000);

// 1. visibilityOfAllElementsLocatedBy

By titleLocator = By.xpath(“//button[@data-test-id=’list-view-button’]”);
List titles = wait.until(ExpectedConditions.visibilityOfAllElementsLocatedBy(titleLocator));
int titleCount = titles.size();
System.out.println(“Number of titles” + titleCount);

By authorLocator = By.xpath(“//button[@data-test-id=’list-view-button’]”);
List author = wait.until(ExpectedConditions.presenceOfAllElementsLocatedBy(authorLocator));
int authorCount = author.size();
System.out.println(“Number of authors” + authorCount);

driver.quit();
}
}

Summary of ExpectedConditions checks supported by Selenium:

S.No. return Type => Function => Description
1 static ExpectedCondition => alertIsPresent() => webalert is present
2 static ExpectedCondition => and(ExpectedCondition… conditions) => An expectation with the logical and condition of the given list of conditions.
3 static ExpectedCondition => attributeContains(org.openqa.selenium.By locator, String attribute, String value) => An expectation for checking WebElement with given locator has attribute which contains specific value
4 static ExpectedCondition => attributeContains(org.openqa.selenium.WebElement element, String attribute, String value) => An expectation for checking WebElement with given locator has attribute which contains specific value
5 static ExpectedCondition => attributeToBe(org.openqa.selenium.By locator, String attribute, String value) => An expectation for checking WebElement with given locator has attribute with a specific value
6 static ExpectedCondition => attributeToBe(org.openqa.selenium.WebElement element, String attribute, String value) => An expectation for checking given WebElement has attribute with a specific value
7 static ExpectedCondition => attributeToBeNotEmpty(org.openqa.selenium.WebElement element, String attribute) => An expectation for checking WebElement any non empty value for given attribute
8 static ExpectedCondition => elementSelectionStateToBe(org.openqa.selenium.By locator, boolean selected) => An expectation for checking if the given element is selected.
9 static ExpectedCondition => elementSelectionStateToBe(org.openqa.selenium.WebElement element, boolean selected) => An expectation for checking if the given element is selected.
10 static ExpectedCondition => elementToBeClickable(org.openqa.selenium.By locator) => An expectation for checking an element is visible and enabled such that you can click it.
11 static ExpectedCondition => elementToBeClickable(org.openqa.selenium.WebElement element) => An expectation for checking an element is visible and enabled such that you can click it.
12 static ExpectedCondition => elementToBeSelected(org.openqa.selenium.By locator) => An expectation for checking if the given element is selected.
13 static ExpectedCondition => elementToBeSelected(org.openqa.selenium.WebElement element) => An expectation for checking if the given element is selected.
14 static ExpectedCondition => frameToBeAvailableAndSwitchToIt(org.openqa.selenium.By locator) => An expectation for checking whether the given frame is available to switch to.
15 static ExpectedCondition => frameToBeAvailableAndSwitchToIt(int frameLocator) => An expectation for checking whether the given frame is available to switch to.
16 static ExpectedCondition => frameToBeAvailableAndSwitchToIt(String frameLocator) => An expectation for checking whether the given frame is available to switch to.
17 static ExpectedCondition => frameToBeAvailableAndSwitchToIt(org.openqa.selenium.WebElement frameLocator) => An expectation for checking whether the given frame is available to switch to.
18 static ExpectedCondition => invisibilityOfAllElements(List elements) => An expectation for checking all elements from given list to be invisible
19 static ExpectedCondition => invisibilityOfElementLocated(org.openqa.selenium.By locator) => An expectation for checking that an element is either invisible or not present on the DOM.
20 static ExpectedCondition => invisibilityOfElementWithText(org.openqa.selenium.By locator, String text) => An expectation for checking that an element with text is either invisible or not present on the DOM.
21 static ExpectedCondition => javaScriptThrowsNoExceptions(String javaScript) => An expectation to check if js executable Usefull when you know, that there should be js val or something at the stage
22 static ExpectedCondition
