- A. system
- B. functional
- C. component
- D. integration
Answer: D
Explanation:
Integration testing is a type of testing conducted to evaluate the interfaces and interactions between different modules of source code. Here's why integration testing is the correct choice:
* Definition: Integration testing focuses on verifying that the modules or components of an application work together as expected. It checks for data flow between modules and ensures that integrated units function correctly.
* Scope: Unlike system testing (which tests the entire system) or component testing (which tests individual components), integration testing specifically targets the interactions and interfaces between modules.
* Purpose: The goal is to identify issues that arise when combining components, such as incorrect data exchange, communication errors, and interface mismatches.
NEW QUESTION # 101
Which of the following software metrics is based on a nominal scale-1
- A. Severing of a defect, critical, major, minor, etc.
- B. Root cause of defect, logic error data definition, etc
- C. Defect density: number per function point, etc.
- D. Defect discovery rate: number detected per day, etc.
Answer: B
Explanation:
Nominal scales are used in measurement to categorize data without any order or priority. They are the simplest form of measurement scale and are used to group items into distinct categories based on names or labels123.
* Root cause of defect (Option A): This fits the nominal scale as it involves categorizing defects based on their root causes, such as logic errors or data definitions. These categories are mutually exclusive and do not have a natural order1.
* Severity of a defect (Option B): This is an example of an ordinal scale, not a nominal scale. The severity levels (critical, major, minor) imply a ranking or order of importance or impact2.
* Defect density (Option C): This metric uses a ratio scale as it involves a quantitative measure (number of defects) relative to the size of the software (function points), which has a true zero point and allows for meaningful comparisons between measurements2.
* Defect discovery rate (Option D): This is also a ratio scale because it measures the rate of defect detection over time (number detected per day), which is a quantitative assessment that allows for arithmetic operations
NEW QUESTION # 102
Which of the following activities would be most appropriate for mitigating the risk of releasing patches to software?
- A. Partial releases
- B. Regression testing
- C. Software rebuilds
- D. Configuration management
Answer: B
Explanation:
Regression testing is crucial when releasing patches as it ensures that the new changes have not adversely affected the existing functionality of the software. It involves re-running previous tests on the modified software to confirm that the old functionalities still work as expected and that the new patches do not introduce new defects.
Partial releases, software rebuilds, and configuration management are important aspects of software maintenance, but regression testing directly addresses the risk of introducing new issues with patches.
