QTP QuickTest Professional Testing

Setting an empty string using WebEdit().Set works consistently across IE and Firefox without needing to change to a space. Both browsers handle empty string assignments the same way in QTP's object model.

The DOM is largely standardized by W3C specifications, so IE and Firefox implement similar core DOM structures. While there are implementation differences and browser-specific extensions, the fundamental DOM architecture is not 'totally different' between the two.

QTP handles requests differently between IE and Firefox because the browsers use different rendering engines and QTP hooks into them differently. The request patterns, object identification, and event simulation vary between browsers.

Popup handling differs between IE and Firefox due to different window management, JavaScript dialog implementations, and how QTP identifies and interacts with popup windows. The characteristics, timing, and recognition patterns for popups vary between browsers.

Scripts recorded with low-level recording in Internet Explorer use IE-specific APIs and ActiveX controls that are not compatible with Firefox. The recording captures browser-specific implementation details that cannot be executed across different browsers.

QTP 9.2 (QuickTest Professional) comes with default add-ins for ActiveX, Visual Basic, and Web testing. These are the core add-ins installed by default for testing common application types.

In QTP (QuickTest Professional), Ctrl+R is the keyboard shortcut to open the Object Repository window. This provides quick access to view and manage test objects. The option has a minor typo ('Crl' instead of 'Ctrl') but the intended answer is correct.

QTP (QuickTest Professional) has 8 built-in toolbars in its standard interface. These provide access to commonly used features like recording, playback, debugging, and object management.

The Debug Viewer Pane in QTP/UFT contains three tabs: Command (for executing commands), Watch (for watching variables), and Variables (for viewing variable values). This combination helps in debugging by allowing you to execute commands, monitor specific variables, and inspect all variables at runtime.

The Information Pane in QTP displays syntax errors that are detected during test execution or debugging. This pane provides real-time feedback on code issues, helping testers identify and fix errors quickly.

In QTP, the Local Object Repository is embedded within the test or action file and is not accessible as a separate file. In contrast, the Shared Object Repository is stored as a separate .tsr file that can be accessed and reused across multiple tests.

QTP allows you to work with multiple function libraries simultaneously. You can associate several function libraries with a test and call functions from any of them during test execution. This promotes code reusability and modular testing.

Both Wait and Exist statements can instruct QTP to wait for an object. The Wait statement pauses execution for a specified time, while Exist checks if an object exists and can be used in a loop to wait for the object to appear. Both achieve the goal of waiting until an object exists.

In QuickTest Professional (QTP) / Unified Functional Testing (UFT), the keyboard shortcut Ctrl+F5 is used to run the test session starting from the currently selected step.

Regression testing involves re-running previously executed tests to verify that unchanged parts of the software still work after changes. Test capture and replay tools are most beneficial here because the same tests need to be executed repeatedly after each code change, making automation highly valuable.

Error guessing is an experience-based technique where testers use their intuition to guess where defects might exist. It supplements formal test design techniques (like boundary value analysis or equivalence partitioning) by adding informal, heuristic-based test cases. It can be used at any testing level and is repeatable when documented.

User Acceptance Testing (UAT) validates that the system meets user needs and business requirements. Therefore, the user requirements document is the best source for expected outcomes because it defines what users actually need from the system. System specifications focus on technical implementation, while actual results are what you observe during testing.

Regression testing verifies that unchanged areas of software still work correctly after modifications. Its purpose is to detect unintended side effects in parts of the system that weren't directly modified. It doesn't focus on changed areas (that's the job of other tests) and can be manual or automated at any test level.

Alpha testing is pre-release testing conducted at the developer's site by end user representatives or independent test team. It happens before beta testing (which is at users' own sites) and before general release. Option A incorrectly states post-release, option B is wrong (unit testing comes first), and option D describes beta testing.
