Handling Checkboxes and Radio Buttons

 Checkboxes and radio buttons are fundamental elements in web forms, allowing users to make selections with a click. Automating interactions with these controls is a key part of web application testing. Despite their simplicity, they often require careful handling in test scripts, especially when dealing with dynamic states, custom designs, or hidden elements.

Understanding the Elements

Checkboxes allow users to select multiple options independently.

Radio buttons permit only one selection in a group, making them ideal for single-choice scenarios like gender or payment method.

In HTML, these elements are typically defined as:

<input type="checkbox" id="subscribe">

<input type="radio" name="gender" value="male">

While the basic structure is straightforward, their behavior can vary depending on how developers implement custom styles or logic in JavaScript.

Automating with Selenium

Selenium handles checkboxes and radio buttons using simple click() actions and the isSelected() method to check their state.

WebElement checkbox = driver.findElement(By.id("subscribe"));

if (!checkbox.isSelected()) {

    checkbox.click();

}

WebElement radio = driver.findElement(By.id("gender-male"));

radio.click();

This ensures the checkbox is selected only if it isn’t already, preventing unintended toggles.

Automating with Cypress

Cypress simplifies interaction with these elements using commands like check() and uncheck() for checkboxes, and check() for radio buttons.

cy.get('#subscribe').check(); // for checkbox

cy.get('input[name="gender"]').check('male'); // for radio button

Cypress also automatically waits for elements to be actionable, reducing flakiness in tests.

Automating with Playwright

Playwright offers similar control with methods like check(), uncheck(), and isChecked():

await page.check('#subscribe'); // checkbox

await page.check('input[value="male"]'); // radio

Playwright ensures the element is visible and enabled before performing the action.

Best Practices

Check element state before clicking, especially for checkboxes.

Use stable selectors like IDs or data attributes to avoid brittle tests.

Avoid relying solely on visual checks (e.g., color or style) to determine state.

Handle custom-styled inputs carefully, ensuring the underlying <input> is targeted.

Conclusion

Handling checkboxes and radio buttons in automation scripts may appear simple, but doing it reliably across different frameworks requires precision. Whether using Selenium, Cypress, or Playwright, understanding their behavior and applying best practices ensures accurate, maintainable, and stable test cases. Mastering these basic UI components builds a strong foundation for broader web testing success.

Understanding the useEffect Hook

 React is primarily used for building user interfaces, where components re-render based on changes in state or props. But real-world applications often need to interact with external systems—fetching data, subscribing to events, updating the DOM, or starting timers. These are known as side effects, and React’s useEffect hook is the tool designed to handle them in functional components. What is useEffect? The useEffect hook lets you perform side effects in your component. It's React’s way of combining several lifecycle methods from class components (like componentDidMount, componentDidUpdate, and componentWillUnmount) into a single, unified API. Syntax : useEffect(() => {   // side effect code   return () => {     // cleanup code (optional)   }; }, [dependencies]); The first argument is a function containing your side effect logic. The optional second argument is a dependency array that controls when the effect runs. jsx Basic Example import React, { u...

Exception Handling in Java

In Java, exception handling is a powerful mechanism that helps developers manage runtime errors, ensuring the smooth execution of programs. Rather than crashing the program, exceptions allow you to identify the error, handle it gracefully, and keep the application running. What Is an Exception? An exception is an unwanted or unexpected event that disrupts the normal flow of a program. These can be caused by user errors, logic errors, or system issues. Java categorizes exceptions mainly into two types: Checked Exceptions – Handled during compile-time (e.g., IOException, SQLException). Unchecked Exceptions – Occur during runtime (e.g., NullPointerException, ArithmeticException). Why Handle Exceptions? Without exception handling, an error can cause your program to terminate unexpectedly. Handling exceptions: Increases program reliability Helps in debugging and troubleshooting Improves user experience by displaying meaningful error messages Basic Exception Handling Syntax Java provides fiv...
