Imagine a situation where a software application's performance metrics are within an acceptable range under normal conditions, but it crashes during company-wide events when most employees access it. Which type of testing might have prevented this situation?
- Alpha Testing
- Functional Testing
- Stress Testing
- Usability Testing
Stress Testing involves assessing the system under extreme conditions beyond its specifications. In scenarios where there's an unexpected surge in users, like company-wide events, it's vital to determine if the software can sustain the stress or if it breaks, thus helping in predicting and preventing potential crashes.
One of the key aspects of resource planning is to allocate tasks based on the tester's _______.
- Availability
- Expertise
- Past Projects
- Tools
In resource planning, it's essential to allocate tasks based on a tester's "Expertise". By doing this, the strengths of each tester are leveraged, ensuring that the testing process is efficient and effective.
When designing test cases, considering the extreme edge values is called _______ analysis.
- Boundary Value
- Edge Value
- Error Guessing
- Performance
Boundary Value Analysis is a software testing technique that involves testing at the boundaries between partitions. It focuses on the values that lie at the "edges" or boundaries of the allowed input and output ranges, as these values often have a higher likelihood of causing errors.
Which of the following best defines a positive test case?
- A test based on negative scenarios
- A test that should fail
- A test that should pass
- A test to identify system vulnerabilities
A positive test case is designed to test the application under positive conditions, and it is expected to pass. Such tests confirm that a feature or functionality works as intended when provided with valid input data.
One of the challenges in test script development is ensuring that scripts are resilient to _______ changes in the application.
- Backend
- Functional
- UI
- Version
UI (User Interface) changes in an application can often break test scripts, especially in automation. This is because automated tests might rely on specific elements, identifiers, or layouts on the interface. Ensuring scripts are resilient to these changes reduces maintenance efforts.
You are leading a testing team for a critical project, and the client wants the project delivered in a shorter duration than initially planned. How would you adjust your test strategy to meet this requirement?
- Allocate more resources to the testing phase.
- Break the testing into parallel tasks.
- Focus only on high-priority test cases.
- Skip the testing phase altogether.
Focusing on high-priority test cases ensures that the most crucial functionalities are tested, reducing the risk of critical defects. While allocating more resources can be helpful, it might not always be feasible. Skipping testing altogether is not recommended due to high risks. Parallelizing tasks could help but prioritizing guarantees the most important areas are covered.
Which scenario best illustrates a limitation of manual testing?
- A complex application requires testing for hundreds of input fields.
- A single webpage needs a quick visual check.
- A software constantly evolves with regular updates.
- A test script is executed flawlessly the first time.
Manual testing can become tedious and error-prone, especially for repetitive tasks or scenarios with extensive data inputs. Testing a complex application with numerous input fields manually can increase the risk of missing defects due to human error or oversight.
When using the "stubs" and "drivers" approach in testing, which form of integration testing is typically being employed?
- Big Bang
- Bottom-Up
- Sandwich
- Top-Down
"Stubs" and "drivers" are used in Bottom-Up integration testing. Stubs are used to simulate lower modules (that are yet to be developed) while drivers simulate higher modules. It ensures that the main logic is tested early on.
Which review process is informal and led by the author of the software item under review?
- Audit
- Formal Review
- Inspection
- Walkthrough
A Walkthrough is an informal review process led by the author of the software item being reviewed. It's a form of peer review where participants can ask questions and make comments about possible issues. It doesn't have a fixed process and is generally considered to be more collaborative and flexible.
Imagine you're working on a complex application with multiple interconnected subsystems. Post integration of these systems, you want to ensure the entire system functions correctly as a whole. What type of testing should you focus on?
- Boundary Testing
- Integration Testing
- Regression Testing
- Unit Testing
Integration Testing is specifically focused on the interfaces between units/modules and the interactions between different parts of a system. When multiple subsystems are interconnected, Integration Testing helps ensure that they all work together as expected, and there aren't any issues or data losses when data is passed from one subsystem to another.
