How does cyclomatic complexity assist in white-box testing?
- Assesses risk in code logic
- Counts number of defects
- Determines code coverage needs
- Measures code readability
Cyclomatic complexity, introduced by Thomas McCabe, quantifies the complexity of a program by calculating the number of linearly independent paths through the source code. A higher cyclomatic value indicates a complex program with many branches, which may require more extensive testing to ensure each path is evaluated. It aids testers in assessing risks associated with the intricate logic of the code.
As a network administrator, you receive a report from your vulnerability scanner that a certain service is running on an open port which shouldn't be. What immediate action should be considered?
- Disable the service
- Increase firewall settings
- Monitor network traffic
- Run a malware scan
Disabling the service is the immediate action to consider when an unauthorized service is running on an open port. This will prevent potential exploitation while the situation is further assessed. Running a malware scan is important, but the immediate threat is mitigated by stopping the service.
Functional testing for mobile apps often includes validating the app's _______ to ensure they produce the desired outcomes.
- colors
- developers
- features
- sizes
Functional testing aims to validate the app's features by ensuring they function according to specified requirements. It verifies each function of the software application by feeding them input and examining the output.
In Selenium, to automate browser interactions, testers use the _______ to write test scripts.
- JUnit
- Maven
- TestNG
- WebDriver
Selenium provides a tool named WebDriver, which allows testers to write scripts that can automate browser interactions. WebDriver provides a simple API to interact with browsers, making it easier for testers to create automation scripts for web applications without having to know intricate browser details.
When assessing the colors, fonts, and images in an application to ensure a positive user experience, which type of testing are you most likely conducting?
- Compatibility Testing
- GUI Testing
- Load Testing
- Security Testing
GUI (Graphical User Interface) Testing primarily focuses on the visual aspects of an application, ensuring that the colors, fonts, images, and other UI elements are presented correctly and provide a positive and consistent user experience. This helps in making the application visually appealing and user-friendly.
QTP, now known as _______ , is a proprietary tool used for functional and regression testing.
- Quality Test Professional
- Quality Testing Prime
- QuickTech Pro
- Unified Functional Testing
QTP stands for QuickTest Professional. However, it was later rebranded by Hewlett-Packard (HP) as "Unified Functional Testing" (UFT). UFT provides a comprehensive solution for functional and regression testing and is one of the most popular tools in the testing industry for automating GUI testing tasks.
In the STLC, what factors determine the exit criteria of a testing phase?
- Customer feedback
- Number of test cases passed
- Personal judgment of testers
- Pre-defined set of conditions achieved
Exit criteria in the Software Testing Life Cycle (STLC) are a pre-defined set of conditions or metrics which must be achieved to conclude a testing phase. These conditions could include factors like achieving a certain percentage of test coverage, a limited number of high-severity defects remaining open, meeting performance benchmarks, etc. Having a clear exit criteria ensures that a testing phase achieves its intended quality objectives before moving to the next phase.
In white-box testing, which technique involves ensuring that every decision point (true and false) has been executed at least once?
- Cyclomatic Complexity
- Decision Coverage
- Path Coverage
- Statement Coverage
Decision Coverage in white-box testing ensures that each decision point or branch has been executed for both 'true' and 'false' conditions. It is more robust than simple statement coverage because it ensures that each decision leads the control flow in both directions.
Automated test suites are primarily managed using _______ tools to ensure organized execution.
- Compiler
- Debugger
- Test Management
- Version Control
Automated test suites, which consist of a collection of test scripts, test data, and execution sequences, require effective management to ensure organized execution and reporting. Test Management tools offer capabilities to define, organize, and execute tests, as well as to report defects and generate metrics, streamlining the automation workflow.
The role responsible for ensuring all test activities are completed within the stipulated time and budget is the _______.
- Automation Specialist
- QA Analyst
- Test Engineer
- Test Manager
The Test Manager oversees the entire testing process and ensures that all testing activities align with the project timelines and budget. They coordinate between stakeholders and the testing team, ensuring that the testing phase progresses smoothly.
