Top automation testing interview questions in 2024
#1 Why do you think we need Automation Testing?
- “I strongly believe in the value of automation testing for several key reasons.
- First and foremost, it speeds up our development process considerably. We can execute far more tests in the same timeframe, identifying issues early on.
- This means faster fixes, fewer delays, and ultimately getting new features into the hands of our users sooner.
- Automation makes our product far more reliable. Tests run consistently every time, giving us a level of trust that manual testing alone can’t match, especially as our applications grow.
- Automated suites scale effortlessly with the code, guaranteeing that reliability is never compromised.
- From a cost perspective, while an initial investment is needed, automation quickly starts paying for itself. Think about the time developers save rerunning regression tests, the faster turnaround on bug fixes, and the prevention of expensive production failures.
- Beyond that, automation lets our QA team be strategic. Instead of repeating the same basic tests, they can focus on exploratory testing, digging into intricate user flows, and edge cases where human analysis is truly needed. This ensures more comprehensive, thoughtful testing.
- Automation changes how we think about development. It encourages ‘design for testability’, with developers writing unit tests alongside their code.
- This creates more robust systems from the get-go, preventing surprises later. It fits perfectly with modern DevOps practices, allowing us to test continuously and iterate quickly, a real edge in a competitive market.”
“I use a few key criteria to determine if a test is a good candidate for automation:
- Repetition: How often will this test need to be run? Automation excels with tests executed across multiple builds or with varying data sets.
- Stability: Tests for unchanging, mature features are ideal for automation, minimizing maintenance overhead.
- Risk: Automating tests covering critical, high-risk functionalities provides a valuable safety net against regressions.
- Complexity: Time-consuming or error-prone manual tests significantly benefit from automation’s precision and speed.
#3 What are the best practices for maintaining automation test scripts?
“To ensure a robust and adaptable automation test suite, I adhere to a number of core principles:
-
Page Object Model (POM): I firmly believe in the POM pattern. By encapsulating UI element locators separately from the test logic, I introduce a layer of abstraction that significantly increases maintainability. A centralized object repository means changes to the UI often only require updates in a single location, dramatically reducing the impact on the wider test suite.
-
Modular Design & Reusability: I break down test scripts into reusable functions and components. This promotes code efficiency, prevents redundancy, and makes it simple to update individual functionalities without disrupting the entire suite.
-
Meaningful Naming Conventions & Comments: Clear, descriptive naming for variables, functions, and tests, along with concise comments, ensure the code is self-documenting. This is crucial not only for my own understanding but also for streamlined team collaboration and knowledge sharing.
-
Version Control: Leveraging a system like Git is essential. I can track every change, easily revert if needed, and facilitate a collaborative approach to test development.
-
Data-Driven Testing: I decouple test data from the scripts themselves, using external files (like Excel or CSV) or even databases. This allows for executing tests with diverse input scenarios, enhancing coverage while simplifying both updates and troubleshooting.
-
Regular Reviews & Refactoring: I don’t treat maintenance as a reactive task. Proactive code reviews let me identify areas for optimization, remove outdated logic, and continuously improve the suite’s efficiency.
Beyond the Technical: I recognize that successful test maintenance involves a strong team approach. I prioritize open communication channels with developers and emphasize shared ownership of the automation suite to ensure it remains a valuable asset as the application evolves.”
“While I’m a strong advocate of automation, I recognize that certain scenarios are better suited for manual testing or a hybrid approach. I made this decision based on several factors:
-
Unstable or Rapidly Changing Features: Automating tests for areas of the application in active flux can be counterproductive. Frequent UI or functionality changes would require constant script updates, creating more maintenance work than value.
-
Exploratory Testing: Tasks requiring human intuition and creativity, like evaluating user interface aesthetics or uncovering unexpected edge cases, are best handled by skilled manual testers.
-
One-Off Tests: If a test only needs to run once or twice, the time spent automating it might not be worth it.
-
Resource Constraints: If I’m working with limited time or a small team, I might prioritize automating high-risk, repetitive tests while carefully selecting other areas where manual testing may be more efficient.
-
Proof of Concept: During early project phases, manual exploration can help define requirements and uncover potential automation use cases.
Crucially, I see this as a dynamic decision. A test initially deemed unsuitable for automation might become a candidate later once the feature stabilizes or the team’s resources expand.”
#5 Tell me about your experience with Selenium?
“I have significant experience working with the Selenium suite, particularly Selenium WebDriver for web application testing. My focus lies in developing robust and maintainable test automation frameworks tailored to specific project needs.

- Benefits:
- Efficiency: Execute a wide range of test scenarios with minimal code changes.
- Scalability: Easily expand test coverage as new data sets become available.
- Maintainability: Updates to test data don’t require modifying the core test scripts.
Implementation in an Automation Framework
- Data Source:
- External Files: Commonly used formats include CSV, Excel, or even databases.
- Data Generation: For large or complex data sets, consider coding solutions or tools to generate realistic test data.
- Integration with Test Scripts:
- Data Providers: Use the features offered by testing frameworks (like TestNG or JUnit) to read data from the source of your choice and feed it into tests.
- Parameterization: Parameterize your test methods to accept input values from the data provider.
- Looping: Use loop constructs to iterate through each row of data, executing the test logic with each set of input values.
Example:
Consider testing a login form with multiple username/password combinations. A data-driven approach would involve storing the credentials in an external file and using your framework to read and pass each combination to the test script.
Beyond the Technical: I always consider maintainability when implementing data-driven testing. A well-structured data source and clear separation of data from test logic make it easier for the team to update or expand test scenarios.
#10 There are a few conditions where we cannot use automation testing for Agile methodology. Explain them.
While automation testing offers significant benefits in Agile, there are situations where manual testing remains the preferred approach:
-
Exploratory Testing: Agile methodologies emphasize rapid development and innovation. Exploratory testing, where testers freely explore the application to uncover usability issues or edge cases, is often crucial in early stages. Automation is less suited for this type of open-ended, creative exploration.
-
Highly Volatile Requirements: When project requirements are constantly changing, automating tests can be counterproductive. The time spent creating and maintaining automated scripts might be wasted if core functionalities are frequently revised.
-
Low-Risk Visual Elements: Certain visual aspects, like layout or aesthetics, may not warrant automation. Manual testing allows testers to leverage their human judgment and provide subjective feedback on user experience.
-
Limited Resources: If your team is small or has limited time for automation setup, focusing manual efforts on critical functionalities might be a better use of resources. Invest in automation when it demonstrates a clear ROI for your specific project.
-
Proof-of-Concept Stages: During initial development phases, manual testing helps gather valuable insights to inform automation decisions later. Once core functionalities solidify, you can identify the most valuable test cases for automation.
#11. What are the most common types of testing you would automate?
“I focus on strategically automating tests that offer the highest return on investment within our development process. Here are the primary categories I prioritize:
-
Regression Testing: Every code change has the potential to break existing functionality. A comprehensive automated regression suite provides a safety net, allowing us to confidently make changes and deploy updates frequently.

- Automation testing with an unfixed UI, and constantly changing UI can be a risky task.
- Automating an unstable system can be risky too. In such scenarios, the cost of script maintenance is very high.
- If there are some test cases to be executed once, it is not a good idea to automate them.
#13 Explain the tree view in automation testing?
Understanding Tree Views
In the context of automation testing, a tree view represents the hierarchical structure of elements in a web page or application interface. Each node in the tree represents a UI element, and its branches depict the parent-child relationships between elements.
Why Tree Views are Important in Automation
- Unique Identification: Tree views help automation scripts accurately identify elements, especially when those elements lack distinctive attributes like fixed IDs. Testers can traverse the tree structure using parent-child relationships to pinpoint their target.
- Dynamic UI Handling: If the application’s interface changes, using a tree view can make test scripts more resilient. Adjusting paths within the tree might be sufficient, rather than completely overhauling object locators.
- Test Case Visualization: Tree views can present test steps in a logical format that reflects the way users interact with the interface.
Example of How It’s Used
Imagine a test to verify the “Contact” link. An automation script could use the tree structure:
- Locate the top-level “Website” element.
- Find the “Contact” child element within the structure.
- Click the “Contact” element
Automation Tool Support
Many testing tools have built-in features to interact with tree views:
- Selenium WebDriver: Provides methods to locate elements by traversing the tree structure (using XPath or other strategies).

-
Structured Scripting: Introduces programming concepts like conditional statements (if-else), loops (for, while), and variables. This enables more adaptable tests and basic data-driven execution.
-
Data-Driven Scripting: Separates test logic from test data. Data is stored in external sources (like spreadsheets, CSV files, or databases) and dynamically fed into tests, allowing for a single test to be executed with multiple input sets.
-
Keyword-Driven Scripting: Builds a layer of abstraction through keywords that represent high-level actions. This makes tests readable for even non-technical team members, but requires more up-front planning and implementation.
-
Hybrid Scripting: Combines the strengths of various techniques to achieve a balance of maintainability, data-driven flexibility, and ease of understanding.
Beyond the Basics
-
Behavior-Driven Development (BDD): Uses a natural language syntax (like Gherkin) to define test scenarios, fostering collaboration between business analysts, developers, and testers.
-
Model-Based Testing (MBT): Employs models to represent application behavior. These models can automatically generate test cases, potentially reducing manual test design efforts.
Choosing the Right Technique
In an interview, you should emphasize that there’s no single “best” technique. The selection depends on factors like:
- Team Skillset: The complexity of the technique should match the team’s technical abilities.
- Application Complexity: Simple applications might suffice with linear scripting, while complex ones benefit from more structured approaches.
- Test Case Nature: Data-driven testing is ideal for scenarios with multiple input variations.

In an interview, You’d also have to highlight:
- My personal experience: I could give examples of when I’ve used exploratory testing to effectively uncover problems that led to improvements in automated suites.
#33 Describe your plan for automation testing of e-commerce web applications, focusing on the checkout process and inventory management features.
Understanding the Focus Areas
“First, I want to ensure I’m crystal clear on the key functionalities we’re targeting. For the checkout process, that means ensuring a smooth, secure, and accurate experience for the customer. Testing must cover everything from adding items to the cart, all the way through applying discounts, processing payments, and confirming the order.
For inventory management, my primary goal is to ensure total synchronization between the website’s displayed stock and the actual inventory system. Are there any specific pain points or known areas of concern within either of these that I should be especially aware of?”
Test Strategy and Approach
“Given the critical nature of these features, I’d recommend a mixture of scripted and exploratory testing.
- Scripted Automation: I’d prioritize building a core suite of automated tests using a tool like Selenium WebDriver. This would cover the fundamental checkout flows with different test data to simulate various customer scenarios, payment options, and potential errors.
- Exploratory Testing: This is especially important for the user experience side of checkout. I’d want to spend time putting myself in the customer’s shoes to proactively try and discover usability issues or unclear messaging that could cause frustration.
For inventory, I’d likely use an API testing tool alongside my UI tests. This allows me to directly query the inventory system and ensure immediate updates and accurate stock levels are reflected on the frontend.”
Collaboration and Continuous Improvement
“Strong communication with both development and business stakeholders is key in this area. I want to understand any past issues with payment gateways, inventory discrepancies, or user complaints that can help refine my test cases. Ideally, my automated tests would be integrated into the CI/CD pipeline to provide rapid feedback after each code change.”
Irrespective of the choice of your automation tools like SilkTest, QTP, Selenium or any other test tool you can follow the following rules
#34 How do you ensure test coverage across various user personas or roles in your automation testing?

- Collaboration: I’d work closely with stakeholders (product owners, marketing, UX) to define distinct user personas based on their goals, behaviors, and technical expertise. It’s crucial to go beyond basic demographics.
- Examples: A persona might be a “casual shopper” who primarily browses, a “coupon-savvy customer” focused on deals, or an “administrator” managing inventory.
2. Role-Specific Test Scenarios
- Targeted Flows: For each persona, I’d map out their typical journeys through the application. An admin wouldn’t need a full checkout test, while a casual shopper might require usability tests emphasizing search and navigation.
- Permissions: If the system has role-based access, I’d carefully design tests to validate both allowed actions and ensure restricted actions are correctly blocked for each persona.
- Data-Driven Approach: Use data sets with information tailored to each persona (e.g., preferred payment methods, shipping addresses) to make tests more realistic.
3. Test Suite Organization
- Modularization: Create reusable code blocks for actions common to multiple personas (login, search, etc.). This aids maintainability and makes persona-specific variations easier.
- Clear Labeling or Tagging: Tagging tests by persona allows easy filtering and execution of targeted test suites as needed.
4. Prioritization and Expansion
- Critical First: Focus on the personas driving core business functions. A smooth experience for the typical buyer is often paramount.
- Ongoing Collaboration: Stay in touch with the team regarding any changes to user profiles or the introduction of new roles, necessitating test suite updates.

- Real-World Examples: mention cases where role-based testing uncovered unexpected issues or guided prioritization.
35. What are the key differences between scripted and scriptless automation testing approaches?
Scripted Testing
- Coding-Centric: Requires testers to have programming expertise (Java, Python, etc.) to write detailed test scripts that dictate every action and expected result.
- Flexibility: Offers immense customization for complex test scenarios, fine-grained control, and integration with external tools.
- Maintenance: Can be time-consuming to maintain as application updates often necessitate changes to the underlying test scripts.
Scriptless Testing
- Visual Interface: Leverages visual modeling, drag-and-drop elements, or keyword-driven interfaces for test creation. Testers don’t need traditional coding skills.
- Accessibility: Enables non-technical team members (business analysts, domain experts) to participate in testing.
- Faster Initial Setup: Test cases can often be built more quickly in the beginning compared to scripted approaches.
- Potential Limitations: Might be less adaptable for highly intricate test scenarios or custom integrations compared to the full flexibility of scripted testing.
In an interview,you’d have to further emphasize:
- Context Matters: The best approach depends on the project’s complexity, the team’s skillsets, and the desired speed vs. long-term maintainability balance.
- Hybrid Solutions: Many projects benefit from a mix of scripted and scriptless techniques to leverage the strengths of both.

#48 Which tools are you well-acquainted with?
List out the tools you have used, however, make sure that you have experience in handling Selenium
Here are some interview questions based on Selenium automation tool
49. Can we automate CAPTCHA or RECAPTCHA?
The Short Answer:
Fully automating CAPTCHA/reCAPTCHA is inherently difficult, often undesirable, and goes against their purpose of preventing bots.
However, there are a few approaches with limitations:
Possible, but not Ideal Methods:
- Image Recognition: Some advanced OCR techniques attempt to decode CAPTCHA images, but their success rate is unreliable due to deliberate distortions.
- External Services: Paid services claim to solve CAPTCHAs, but they’re costly, ethically questionable, and often become ineffective as CAPTCHA providers evolve.
- Test Mode Bypass: During development, consider if your testing tools can disable CAPTCHA or leverage test keys provided by reCAPTCHA.
Better Strategies:
- API Testing: If possible, focus your automation on directly testing the underlying backend APIs protected by the CAPTCHA.
- Manual Intervention: For scenarios where the CAPTCHA must be part of the test flow, design tests to pause for manual CAPTCHA solving.
Interview Note: You need to emphasize that attempting to circumvent the core function of CAPTCHA/reCAPTCHA should be carefully considered in context with the specific application and its security needs.
#50 When do you go for manual rather than automated testing?
Exploratory tests, usability testing, ad-hoc testing, etc. require tester skills rather than technical skills. So these testing require manual intervention rather than automation.
#51 Can you discuss the integration of automation testing with defect management systems? How do you track and manage bugs detected during automated testing?
Absolutely! My approach would be
1. Choosing the Right Tool
