Custom ExpectedCondition in Selenium Java - Test Execution Trace

Test Overview

This test demonstrates how to create and use a custom ExpectedCondition in Selenium WebDriver with Java. It waits for a specific element's text to become "Loaded" before proceeding, verifying the page state dynamically.

Test Code - Selenium

Selenium Java

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.WebDriverWait;
import java.time.Duration;

public class CustomExpectedConditionTest {
    public static void main(String[] args) {
        System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
        WebDriver driver = new ChromeDriver();
        try {
            driver.get("https://example.com/loadingpage");

            WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));

            ExpectedCondition<Boolean> textIsLoaded = new ExpectedCondition<Boolean>() {
                public Boolean apply(WebDriver d) {
                    WebElement element = d.findElement(By.id("status"));
                    return "Loaded".equals(element.getText());
                }

                public String toString() {
                    return "text to be 'Loaded' in element with id 'status'";
                }
            };

            wait.until(textIsLoaded);

            WebElement statusElement = driver.findElement(By.id("status"));
            assert "Loaded".equals(statusElement.getText()) : "Status text is not 'Loaded'";

            System.out.println("Test Passed: Status text is 'Loaded'.");
        } finally {
            driver.quit();
        }
    }
}

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts and ChromeDriver is initialized	Browser window opens with a blank page	-	PASS
2	Navigates to https://example.com/loadingpage	Page loads with element id='status' showing initial text (e.g., 'Loading...')	-	PASS
3	Waits up to 10 seconds for element with id 'status' text to become 'Loaded' using custom ExpectedCondition	Page updates element text from 'Loading...' to 'Loaded' dynamically	Checks if element text equals 'Loaded'	PASS
4	Finds element with id 'status' and asserts its text is 'Loaded'	Element text is 'Loaded'	assert "Loaded".equals(statusElement.getText())	PASS
5	Prints success message and closes browser	Browser closes	-	PASS

Failure Scenario

Failing Condition: Element with id 'status' text does not become 'Loaded' within 10 seconds

Execution Trace Quiz - 3 Questions

What does the custom ExpectedCondition in this test check for?

A The element with id 'status' is visible

B The page URL contains 'loadingpage'

C The element with id 'status' has text 'Loaded'

D The element with id 'status' is clickable

Key Result

Creating custom ExpectedConditions allows precise waiting for specific page states, improving test reliability when built-in conditions are insufficient.
