During a review of a website, you notice that images are missing alternative text descriptions. Why is this an accessibility concern?
- It increases page load time.
- It leads to a drop in SEO ranking.
- It makes the website less visually appealing.
- It prevents screen readers from describing the image to users.
Alternative text descriptions are essential for images because they provide a textual description, which screen readers can read out to users who are visually impaired. Without this description, such users won't have context or understanding about the images, which can affect their overall user experience.
A well-defined test strategy focuses on achieving the test objectives and delivering the project with the desired _______.
- Budget
- Quality
- Timeline
- Tools
A well-defined test strategy aims at achieving the testing objectives, which usually revolve around ensuring the "Quality" of the software. Quality assurance is pivotal in ensuring the software meets user needs and is defect-free.
You're testing a new web application and find that some color combinations used in the interface might pose difficulties for color-blind users. What type of accessibility issue is this, and how can it be rectified?
- It's a color contrast issue.
- It's an issue with font styling.
- It's related to page load speeds.
- It's related to page navigation.
Color contrast issues are related to the visibility of text or interface elements against their background, especially for color-blind users. Ensuring a sufficient color contrast ratio can rectify this. Web Content Accessibility Guidelines (WCAG) provides specific standards on contrast ratios to ensure readability and visibility for everyone.
During the _______ phase of STLC, the test environment setup is validated.
- Test Design
- Test Environment Setup
- Test Execution
- Test Planning
During the "Test Environment Setup" phase of the Software Testing Life Cycle (STLC), the environment required for testing is prepared. This involves setting up the test servers, databases, and other resources. The validation ensures that the environment aligns with the requirements for accurate testing.
While performing functional testing for mobile apps, testing the app's interactions with other apps and checking for any interference is known as _______ testing.
- Compatibility
- Concurrency
- Integration
- Interoperability
"Interoperability Testing" ensures that the mobile application can operate and interact as expected with other applications. This ensures that there's no interference or unexpected behavior when two or more apps are used simultaneously.
Which criteria evaluates an automation tool's capability to run tests on different OS, browsers, and devices?
- Learning Curve
- Platform Compatibility
- Scripting Language Support
- Test Report Generation
Platform Compatibility is the criterion that evaluates an automation tool's ability to run tests across different operating systems, browsers, and devices. A tool with high platform compatibility ensures consistent test execution across various environments, making it invaluable for diverse software and application landscapes.
In the context of experience-based techniques, a tester might employ _____ to predict where the software might fail based on past experiences.
- Boundary Testing
- Equivalence Partitioning
- Error Guessing
- Stress Testing
Error Guessing is an experience-based testing technique where testers use their intuition and experience to guess where defects might be located in the software. This technique leverages the tester's past experiences and knowledge of common defect patterns.
How do "big bang" methods differ from a typical non-incremental integration testing approach?
- "Big bang" involves incremental testing of modules
- "Big bang" is focused on system testing only
- "Big bang" is more planned and systematic
- "Big bang" waits for all modules to be developed before testing
The "big bang" approach differs from typical non-incremental methods in that, in the "big bang" approach, the integration testing is deferred until all individual modules are developed. This could lead to challenges in identifying defects because everything is tested at once.
In the context of the bug life cycle, what does the "Deferred" status indicate?
- The bug has been fixed and is awaiting retesting.
- The bug has been rejected.
- The bug is not reproducible.
- The bug will be fixed in the next release.
The "Deferred" status in the bug life cycle indicates that the bug has been acknowledged, but the decision has been made to fix it in a subsequent release. This is typically due to the low severity of the bug or strategic reasons related to the project timeline.
In a situation where you want to deploy a new feature but also have the ability to hide it from certain users, which CI/CD practice would be most beneficial?
- Blue-Green Deployment
- Canary Releases
- Database Versioning
- Feature Toggles
Feature Toggles (also known as feature flags) allow developers to release a version of a product that has new features hidden behind toggles. This ensures that the new feature is not visible to users until the toggle is 'flipped on'. This method provides the flexibility to release a new feature to a subset of users or keep it hidden until it's ready for a broader audience.
