During which type of testing are metrics like throughput, response times, and resource utilization primarily observed?
- Compatibility Testing
- Performance Testing
- Security Testing
- Unit Testing
During Performance Testing, the system's performance is evaluated under various conditions to ensure it meets the desired criteria. Metrics like throughput (transactions per second or tasks per time unit), response times (how long it takes to respond to a request), and resource utilization (CPU, memory usage) are key indicators that help testers understand the system's performance behavior.
What is the primary objective of the Test Planning phase in software testing?
- To define the scope and approach
- To execute test cases
- To identify defects in the code
- To prepare the test environment
The primary objective of the Test Planning phase is to define the scope, approach, resources, and schedule for the testing activities. It involves determining what will be tested, who will do the testing, how the testing will be managed, and the criteria for success. This foundation helps guide all subsequent testing activities.
The process of checking network or system for external-facing vulnerabilities and provides insights into the security posture of a system is called _______.
- Patch Management
- Risk Assessment
- Threat Modeling
- Vulnerability Scan
Vulnerability Scanning is the automated process of proactively identifying security vulnerabilities in an operating system, application, or network. It provides insights into the security posture of a system by identifying known vulnerabilities and evaluating the exposure of the system to threats.
Which of the following testing approaches would most likely employ A/B testing?
- Experimental Interface Testing
- Load Testing
- Performance Testing
- Regression Testing
A/B testing, also known as split testing, involves comparing two versions (A and B) of a web page or app against each other to determine which one performs better. Experimental Interface Testing often uses this method to validate design changes and optimize user experiences.
Continuous Integration tools often use _______ to automatically detect and retrieve the latest code changes.
- Configuration Files
- Databases
- User Inputs
- Webhooks
"Webhooks" are used by Continuous Integration tools to detect code changes in version control systems automatically. When developers push new code or updates, the version control system sends a webhook notification to the CI tool, triggering the build process.
You are tasked with ensuring that a video embedded in a web application is fully accessible. Which measures would be vital to achieve this goal?
- Adding colorful animations to the video.
- Including captions or subtitles.
- Increasing the playback speed.
- Making the video auto-play on page load.
Captions or subtitles are fundamental to making videos accessible. They ensure that people who are hard of hearing or deaf can understand the video's content. Additionally, users who might not have headphones or are in a noisy environment can also benefit from them. Captions improve overall comprehension and engagement with the video content.
You've been asked to automate a series of tests. However, these tests will only be run once. What would be your advice based on best practices for test automation?
- Automate everything possible
- Avoid automation for single runs
- Do a cost-benefit analysis
- Proceed with automation immediately
Test automation often involves initial setup time, script writing, and maintenance. If tests are to be run only once, the effort to automate may outweigh the benefits. It's best practice to avoid automation for tests that won't be repeatedly executed.
During Test Control, when faced with limited resources, what strategy is most effective in prioritizing test cases?
- Focusing on areas with the most recent changes.
- Prioritizing based on risk and criticality.
- Testing based on the expertise of the available team members.
- Testing the oldest modules first.
Test Control involves making decisions based on the status of testing activities. When resources are limited, it's crucial to ensure the most critical and risk-prone areas are tested first. Prioritizing test cases based on risk and criticality ensures that vital functionalities and areas get the needed attention.
When focusing on functional testing for mobile apps, why is it essential to test on both newer and older versions of mobile operating systems?
- Newer versions have enhanced security protocols
- Older versions have different UI elements
- To ensure broad compatibility of the application
- To increase the app download size
Testing on both newer and older versions of mobile operating systems is crucial to ensure the broad compatibility of the application. Users may be on a range of OS versions, and ensuring functionality across this spectrum is vital for user satisfaction and retention. Older versions might have legacy features or compatibility issues, while newer ones might introduce new functionalities or security measures that the app must be compatible with.
In Continuous Integration, what is typically done immediately after code is committed to the source control repository?
- A set of automated tests is run
- Code is archived
- Code is manually reviewed
- The code is deployed to production
After code is committed to the source control repository in a Continuous Integration setup, a set of automated tests is immediately run. These tests are designed to check that the new code changes have not introduced any defects or broken existing functionality. This immediate feedback allows developers to address any issues or bugs instantly, ensuring the codebase remains stable and of high quality.
