_______ 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.
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 white-box testing, the technique that tests paths between pairs of procedural statements is known as _______.
- Condition Testing
- Loop Testing
- Path Testing
- Statement Testing
"Path Testing" is a type of white-box testing technique where the tester identifies all possible paths between pairs of procedural statements and then tests each path. It ensures that all paths in a unit are tested at least once.
