Pune has quietly become a hotspot for automation testing jobs. Many startups and MNCs are shifting from manual testing to automated tools. If you're in Pune and looking to grow in this field, a Selenium Online Course is the smartest way to get started.
But do you know what really happens behind the scenes when you click a button in Selenium? It’s not just a single command. It’s a chain reaction of technical steps that many new learners never explore.
This blog breaks down that hidden flow. It is meant for learners who want more than just theory. You will learn the deeper working of Selenium click events with simple language and useful insights.
How Selenium Finds the Button?
First, Selenium needs to find the button. This is done using locators.
Selenium checks the entire HTML (also called DOM). It uses your given locator to search through the page structure.
But finding it is not enough. The element must be visible and enabled. If not, it will throw errors like “Element not interactable.”
This is a common issue, especially in modern single-page apps. These apps load elements dynamically using JavaScript. That’s why using waits (like WebDriverWait) is important before performing a click.
Pune-based companies working with React or Angular apps face this issue regularly. Automation testers there often rely on ExpectedConditions to manage dynamic elements.
What Happens When You Click?
The click function in Selenium is .click(). The browser receives the command, locates the pixel position of the element, and fires the event.
This process is more than just mechanical:
● It checks the element's current state.
● It simulates the full mouse click, not just the action but the event (mousedown, mouseup, click).
● It lets JavaScript event listeners on the button handle the event.
But here’s a catch. In that case, .click() may fail silently.
That’s why Selenium Testing Training in Pune focuses a lot on JavaScript execution and custom wait conditions.
What If the Click Fails?
Click doesn’t always work.
● Element is hidden.
● Another element is overlapping.
● Page is still loading.
● JavaScript event did not trigger.
● DOM changed after locating the element.
In such cases, experts use JavaScript Executor. This runs JavaScript directly in the browser:
java
CopyEdit
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].click();", element);
This bypasses some of the browser’s UI checks and directly calls the click handler.
Another option is Actions class. It simulates a real mouse movement and click:
java
CopyEdit
Actions action = new Actions(driver);
action.moveToElement(element).click().perform();
These methods are important in complex UIs, especially in SPAs or when dealing with modals and dynamic popups.
How the Browser Responds?
It follows the DOM Event Flow:
● Capture Phase: Event goes from parent to child.
● Target Phase: Event hits the element.
● Bubble Phase: Event goes from child to parent.
Selenium triggers the event at the target phase. But if the event listener is attached during capture or bubble phase, it may not fire correctly. In those cases, custom JavaScript execution is more reliable.
Selenium Training in Delhi covers such scenarios deeply. Delhi-based IT companies have increased demand for testers with deep knowledge of browser event handling.
Also, in cities like Delhi, companies are adopting CI/CD pipelines where fast and reliable automation tests are a must. Testers there can’t afford to let click failures slow down builds.
How Selenium Handles Async JavaScript After Click
When you click a button, it may trigger an action that doesn’t happen instantly. For example, it may send a request to a server and then show a result on the screen. This is called an asynchronous (async) process.
Selenium doesn’t wait by default for these background actions. That’s why your script might click a button, but the next line runs before the result loads. This causes errors like "Element not found" or "Timeout".
To fix this, testers use Explicit Waits like:
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("result")));
This tells Selenium to pause until the result appears. It’s very useful for handling Ajax calls, API-based responses, or loading spinners.
This async challenge is common in enterprise apps across Delhi, where apps handle real-time data. That's why Selenium Training in Delhi now includes async test handling as a core skill.
Sum up,
● Selenium click is not just a click. It includes element detection, interaction simulation, and event triggering.
● You must handle waits, dynamic content, and JavaScript-heavy UIs.
● JavaScript Executor and Actions class are great tools when .click() fails.
● Learn about DOM Event Flow. It can save hours of debugging.
If you're planning a testing career in 2025, understanding the click process deeply is not optional. It’s what separates script writers from true test engineers.Opting for a training in Selenium can help you stay relevant in this tech related industry.
