面试题与答案

QTP is an automated functional testing tool that helps testers to perform automated regression testing on software applications.

QTP is a commercial tool developed by HP for functional testing, while Selenium is an open-source tool mainly used for web application testing.

QTP supports three recording modes: Keyword Driven, Analog, and Low-Level Recording.

Parameterization allows testers to use different sets of data for the same test. QTP supports parameterization through Data Table and Environment Variables.

Object Repository is a collection of objects and properties with which QTP can identify and perform operations on the application under test.

Checkpoints in QTP are used to verify if certain conditions are met during the execution of a test. Examples include text, database, and image checkpoints.

Descriptive Programming is a way to perform operations on objects without adding them to the Object Repository. It involves defining properties and their values in the script itself.

To handle dynamic objects, regular expressions and descriptive programming can be used in QTP scripts.

Regular Expressions in QTP allow testers to create flexible and powerful object recognition criteria by defining patterns for object property values.

Dynamic data in QTP scripts can be handled using parameterization, where the values are supplied during runtime using Data Table or Environment Variables.

The Recovery Scenario Manager in QTP is used to define recovery operations for handling unexpected events during test execution, ensuring the stability of the test.

The Data Table in QTP is used to store data input values for a test and allows testers to parameterize and iterate test cases using different sets of data.

Smart Identification in QTP is a mechanism to identify objects even if they have changed properties, by using base filter criteria and optional properties.

The Object Spy in QTP is used to view and retrieve the properties and methods of the objects in the application under test, helping in script development.

Exceptions in QTP scripts can be handled using the 'On Error' statement, which allows testers to define error-handling routines to manage unexpected errors.

Business Process Testing in QTP allows testers to organize and modularize test components, making it easier to manage and maintain complex test scenarios.

The Keyword View in QTP provides a tabular representation of test steps using keywords, making it easier for non-programmers to create and modify test scripts.

Test results in QTP can be exported in various formats like HTML or PDF using the 'Export' option in the Test Results window.

Synchronization in QTP is used to ensure that the test script waits for the application to respond before performing the next step, preventing timing issues.

Database testing in QTP can be done using SQL queries to verify data integrity and consistency in the application's backend database.

Environment Variables in QTP are used to store and retrieve values that can be referenced across multiple tests, enhancing reusability.

The Object Identification Center in QTP is used to configure and fine-tune the recognition properties of test objects for accurate object identification.

QTP can be integrated with version control systems like SVN or Git by configuring the appropriate settings in the version control tools and QTP.

Shared Object Repositories in QTP allow multiple tests to share a common set of objects, promoting reusability and maintainability.

Step Properties in QTP allow testers to define specific settings and behaviors for individual steps in a test, providing greater control over test execution.

Dynamic web elements in QTP can be handled using regular expressions, making the object identification flexible to changes in properties.

The Resource tab in QTP is used to manage external resources such as libraries, function libraries, and shared object repositories for better test organization.

Pop-up windows in QTP can be handled using the built-in functions and methods provided by QTP, such as 'Dialog', to interact with dialog boxes.

Parameterization using Excel sheets in QTP involves importing data from Excel files using data table methods like 'Import' and 'Export'.

The Test Batch Runner in QTP allows testers to execute multiple tests in a batch, facilitating the automation of regression testing for larger test suites.

QTP can be configured to work with different browsers by installing the appropriate browser add-ins and configuring the browser settings in QTP.

The Global Data Table in QTP is used to store and share data across multiple actions, providing a centralized location for test data.

Image-based testing in QTP involves using the 'Image Checkpoint' and 'Image' functions to verify the presence and properties of images in the application.

Parameterization using Data Table in QTP involves storing and retrieving data from the Data Table during test execution, allowing for data-driven testing.

The QTP Test Merge Tool is used to merge changes between different versions of the same test, facilitating collaborative test script development.

Test data in QTP can be handled using Data Table, Environment Variables, and external sources like Excel sheets or databases for parameterization.

The Test Summary Report in QTP provides a comprehensive summary of test execution results, including pass/fail status, enabling efficient test analysis.

The XML Checkpoint in QTP is used to verify the content and structure of XML documents, ensuring the correct representation of data.

A Virtual Object in QTP is a non-standard object that does not have a corresponding test object class. It allows users to perform operations on non-standard objects.

The Step Generator in QTP is used to add steps to a test or action without having to record them. It helps in enhancing the efficiency of test script creation.

The Test Object Model in QTP provides a set of programming objects that represent the elements in the application under test, facilitating test automation.

Action Splitting in QTP involves breaking down a large test script into smaller, more manageable actions to improve maintainability and reusability.

A Business Component in QTP is a modular and reusable unit that represents a business process or functionality, enhancing test design and maintenance.

The QTP Automation Object Model (AOM) allows testers to control QTP programmatically, enabling the automation of various tasks outside the QTP interface.
