In a situation where the development team wants to integrate and test the functionality of two units that communicate with each other but one unit is not yet fully developed, what approach might be beneficial?
- Bottom-Up Integration
- Sandwich Integration
- Stubs and Drivers
- Top-Down Integration
When one of the interacting units isn't fully developed, "Stubs and Drivers" can be employed. A "Stub" is a simplistic implementation of the missing unit, while a "Driver" simulates a unit that calls the incomplete one. These temporary components allow early testing of interactions between units, without waiting for full development.
Why is exploratory testing often combined with other structured testing techniques in a testing cycle?
- For better test coverage
- To find more defects
- To make testing more exciting
- To reduce testing time
Exploratory testing, being less structured, allows testers to rapidly identify and react to software behavior. When combined with structured testing, it ensures that not only are predetermined test cases being executed, but the tester's experience, intuition, and creativity also come into play to provide a more comprehensive test coverage. This synergistic combination often results in discovering defects that might have been overlooked with only a structured approach.
Which of the following is NOT typically a part of the review process?
- Code execution
- Gathering feedback
- Identifying discrepancies
- Inspecting the product
Code execution is a dynamic activity where the software is run to check its behavior, whereas reviews are a static technique. Reviews focus on inspecting the product, gathering feedback, and identifying discrepancies without actually running the software.
The process of setting up, writing, and maintaining automated tests often requires a(n) _______ investment upfront.
- adaptive
- instantaneous
- minimal
- substantial
Setting up automated tests requires a significant initial investment in terms of time, effort, and resources. This includes selecting the right tools, writing the scripts, and maintaining them to adapt to changes in the application being tested.
In which testing approach is the primary concern the visual elements, layouts, and interactive parts of an application?
- A/B Testing
- Compatibility Testing
- Load Testing
- UI Testing
UI (User Interface) Testing primarily deals with the testing of the visual elements, layouts, and interactive parts of an application. The main goal is to ensure that users have a seamless and consistent visual experience across different functionalities, and that all interactive elements respond as expected.
_______ testing in mobile application testing ensures that the app performs effectively when network conditions change.
- Connectivity
- Load
- Network Transition
- Performance
Network Transition testing focuses on verifying the app's performance and behavior when transitioning between different network conditions, such as moving from WiFi to 4G or experiencing signal drops. It ensures the app remains stable and functional during such changes.
How do frameworks like Page Object Model (POM) influence the choice of an automation testing tool?
- Code Reusability
- Reduced Maintenance Cost
- Reporting Features
- Scalability of the Tool
The Page Object Model (POM) is a design pattern that promotes code reusability in automation scripts. In POM, web pages or segments of them are represented as objects within test scripts. When choosing an automation tool, the tool's ability to easily implement POM and reuse code can significantly streamline test development and maintenance.
A developer has written a new sorting algorithm. To verify its correctness, which type of testing should primarily be applied?
- Acceptance Testing
- Integration Testing
- Performance Testing
- Unit Testing
Unit Testing is the process of verifying individual units or components of a software. Since a sorting algorithm is a singular function or component, unit tests are essential to ensure that it works correctly in isolation. This ensures that the algorithm correctly sorts data under various scenarios before it's integrated with other components.
A company has received feedback that while their application is functional, users find it dull and non-engaging. Which type of testing can help the company address this feedback and improve the application's desirability?
- A/B Testing
- Compatibility Testing
- Functional Testing
- Stress Testing
A/B Testing allows companies to compare two versions of an application (or specific features) to determine which one is more effective in engaging users. By using this method, the company can test new designs or elements to see if they address user feedback about the application being dull or non-engaging.
The process of validating every module's interaction in a specified flow in a complete system environment is termed as _______ testing.
- Integration
- Regression
- System
- Unit
Integration testing focuses on combining units or components of a software and testing them as a group. It's about validating the interactions between different modules or services in a specified flow to ensure they work together as intended in the system's broader environment. Unit testing, on the other hand, checks individual components, while system testing validates the entire application.
