_______ is a process in which individual units or components of a software are tested.
- Acceptance Testing
- Regression Testing
- System Testing
- Unit Testing
"Unit Testing" focuses on the smallest unit of the software design (like functions, methods, or classes). Each unit is tested in isolation to discover any discrepancies between its expected and actual outcomes.
The "think-aloud" method is commonly used in which type of testing?
- Compatibility Testing
- Functional Testing
- Security Testing
- Usability Testing
The "think-aloud" method is used in Usability Testing. Participants are asked to speak their thoughts aloud while they perform tasks, providing insights into their cognitive processes, decision-making, and how they navigate and interact with the interface, highlighting potential usability issues.
Which metric is essential for understanding the efficiency of the testing process by calculating the ratio of the number of defects detected to the number tested?
- Defect Age
- Defect Density
- Defect Detection Percentage
- Test Efficiency
Defect Detection Percentage (DDP) is a vital metric that calculates the ratio of the number of defects detected to the total number tested. It provides insight into the efficiency of the testing process, giving an understanding of how well the testing phase is identifying issues.
You are tasked with setting up automation for a project with multiple microservices written in different programming languages. Which tool would offer flexibility in this scenario?
- Cucumber
- JUnit
- Postman
- Selenium
Postman is a versatile tool designed for API testing. With microservices, the emphasis is often on ensuring API contracts and interactions are reliable. While tools like JUnit and Selenium are great for unit and UI tests respectively, Postman offers the flexibility required for varied microservices.
You are designing an application for elderly users who might not be tech-savvy. Which kind of testing would be crucial to ensure they can use the app effectively and without frustration?
- Load Testing
- Performance Testing
- Security Testing
- Usability Testing
Usability Testing ensures that the designed application is user-friendly, intuitive, and easy to use. Especially for elderly users who might not be familiar with modern tech conventions, ensuring the app's usability is crucial to prevent any potential frustration or challenges during their interaction.
In the context of the principles of software testing, what does "Pesticide Paradox" mean?
- All bugs can be found
- If you keep using the same tests, they become less effective
- Reusing old test cases is enough
- Testing can be endless
The "Pesticide Paradox" principle states that just as pesticides become ineffective when pests develop resistance, similarly, test cases lose their effectiveness if they are not regularly reviewed and updated. New defects can't be found when using the same tests repeatedly.
While working on a new software product, your team identifies that integrating a third-party tool might pose a significant risk due to compatibility issues. What is the best immediate course of action?
- Revert to a previous tool version
- Avoid the integration
- Purchase a new tool
- Continue with the current tool without changes
Opting to avoid the integration is often the best course when significant risks are identified. While the other options may seem viable, they don't directly address the immediate concern of compatibility issues which can lead to significant defects or project delays.
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.
