automation qtp tester Interview Questions and Answers
-
What is QTP (QuickTest Professional)?
- Answer: QTP, now known as UFT (Unified Functional Testing), is a commercial software testing tool used for functional and regression testing of software applications. It uses VB Script as its scripting language to automate test cases.
-
Explain the difference between functional and regression testing.
- Answer: Functional testing verifies that each function of the software application operates as specified. Regression testing ensures that new code changes haven't introduced bugs into previously working functionality.
-
What are the different types of checkpoints in QTP?
- Answer: QTP offers several checkpoint types including standard, bitmap, database, text, table, and XML checkpoints. Each verifies different aspects of the application's UI or data.
-
What is a checkpoint and why is it important?
- Answer: A checkpoint compares the expected value of an application object with its actual value at runtime. It's crucial for verifying that the application behaves as expected and identifying defects.
-
How do you handle dynamic objects in QTP?
- Answer: Dynamic objects have properties that change during test execution. We handle them using descriptive programming, regular expressions, or object identification techniques that rely on stable properties.
-
Explain descriptive programming in QTP.
- Answer: Descriptive programming allows you to identify objects based on their properties instead of relying solely on object repositories. This is beneficial for handling dynamic objects.
-
What is an object repository in QTP?
- Answer: The object repository stores the descriptions of the objects used in your test scripts. It helps organize and manage the objects used in your automation.
-
What are the different types of object repositories?
- Answer: QTP supports local and shared object repositories. Local repositories are specific to a single test, while shared repositories can be used by multiple tests.
-
How do you handle exceptions in QTP scripts?
- Answer: Using `On Error Resume Next` and error handling mechanisms like `try...catch` blocks (though less common in VBScript) to gracefully handle runtime errors and prevent script crashes.
-
What are the different types of actions in QTP?
- Answer: QTP actions can be regular actions, reusable actions, and expert view actions. Reusable actions are modular and can be called from multiple test scripts.
-
Explain the concept of data-driven testing in QTP.
- Answer: Data-driven testing involves running the same test script with different sets of data from an external source (like an Excel sheet). This increases test coverage and efficiency.
-
How do you implement data-driven testing in QTP?
- Answer: By using data tables, external data sources (like Excel or CSV files), and parameters in test scripts to dynamically input data into the application during testing.
-
What is keyword-driven testing?
- Answer: Keyword-driven testing utilizes a table of keywords and actions to describe test cases. This approach separates test design from script implementation, improving maintainability.
-
What is the difference between data-driven and keyword-driven testing?
- Answer: Data-driven focuses on using different data sets for the same test script, while keyword-driven focuses on using keywords to describe actions, making it more abstract and maintainable but potentially less flexible.
-
How do you handle frames in QTP?
- Answer: By using the `Browser("BrowserName").Frame("FrameName").Page("PageName")` syntax or equivalent methods to switch between frames and access elements within them.
-
How do you handle pop-up windows in QTP?
- Answer: Using the `Window("WindowTitle").Activate` or similar methods to identify and interact with pop-up windows, handling them similarly to frames and other application objects.
-
What is the use of regular expressions in QTP?
- Answer: Regular expressions enable the identification of objects with partially known or dynamically changing properties, providing flexibility in object identification.
-
Explain the importance of test automation frameworks.
- Answer: Test automation frameworks provide structure, reusability, maintainability, and reporting capabilities for test automation projects, leading to better efficiency and quality.
-
What are some common QTP test automation frameworks?
- Answer: Data-driven, keyword-driven, modular, hybrid, and page object model (POM) frameworks are commonly used with QTP/UFT.
-
What is the Page Object Model (POM)?
- Answer: POM is a design pattern that separates UI element locators from test logic, enhancing maintainability and reusability of test scripts.
-
How do you generate test results in QTP?
- Answer: QTP automatically generates test results, often in HTML format, detailing test execution status, checkpoints, and any errors encountered.
-
How do you integrate QTP with other tools?
- Answer: QTP can integrate with tools like ALM (Application Lifecycle Management) for test management, source control systems for version control, and other testing tools for comprehensive testing processes.
-
Explain the concept of recovery scenario in QTP.
- Answer: Recovery scenarios handle unexpected events or errors during test execution, allowing the test to continue running instead of failing abruptly. Examples include handling pop-up dialog boxes.
-
How do you handle synchronization issues in QTP?
- Answer: Using synchronization points (like `Wait` statements) or smart identification techniques to ensure that the test script waits for specific application elements or states before continuing.
-
What are the limitations of QTP?
- Answer: High licensing costs, reliance on VBScript (though UFT offers other languages), limitations in handling certain technologies, and the learning curve associated with mastering the tool.
-
What is the difference between QTP and Selenium?
- Answer: QTP is a commercial tool with broader capabilities but higher licensing costs, while Selenium is open-source, supports multiple languages, and is particularly strong in web application testing. QTP offers better support for complex applications and technologies.
-
What are some best practices for writing effective QTP scripts?
