You are working on a program that needs to perform different actions based on the day of the week. Which control statement would be most appropriate to use?
- for
- if-else
- switch
- while
The correct answer is B) switch. The switch statement is ideal for situations where you want to execute different code blocks based on the value of a variable (in this case, the day of the week).
What is the purpose of the fopen function in C?
- Closes a file
- Opens a file for both reading and writing
- Opens a file for reading
- Opens a file for writing
The fopen function in C is used to open a file for reading. It returns a file pointer that can be used to read data from the file.
Which function is used to display output on the console in C?
- display()
- print()
- printf()
- write()
In C, the 'printf()' function is used to display output on the console.
What is the primary goal of security testing?
- To discover software bugs
- To enhance software performance
- To ensure a seamless UI
- To identify vulnerabilities and weaknesses
Security testing primarily aims to identify vulnerabilities, weaknesses, and potential threats in a software application. It is crucial for protecting data from unauthorized access and breaches, ensuring the confidentiality, integrity, and availability of the system.
When is automated testing NOT recommended?
- For frequently changing requirements
- For large-scale projects
- For one-time testing scenarios
- For performance testing
Automated testing involves the initial cost of writing and maintaining scripts, making it not cost-effective for one-time testing scenarios. While automation can handle large-scale projects and performance testing, it's not recommended when the requirements change often.
How do test levels relate to the Test Planning phase?
- Test levels are ignored during test planning.
- Test levels define the sequence of unit, integration, and system testing.
- Test levels determine the software architecture.
- Test levels inform what documentation is necessary.
Test levels, which include stages like unit, integration, system, and acceptance testing, play a critical role in the Test Planning phase. They help in organizing the sequence and scope of testing activities, ensuring that all components of the software are thoroughly evaluated at the appropriate stages.
Which type of test cases are usually NOT a good fit for automation?
- Database test cases
- Exploratory test cases
- Load test cases
- Regression test cases
Exploratory test cases are based on real-time learning and testers' expertise. Automation is not suitable because these tests are often non-repetitive, less predictable, and leverage the human ability to spot unexpected issues in an ad-hoc manner.
Which of the following is a significant benefit of automated testing?
- Elimination of human errors in testing
- Ensuring software is defect-free
- Immediate feedback to developers
- Reduction in testing costs
Automated testing significantly reduces the chances of human errors that can be introduced during manual testing. While it doesn't guarantee defect-free software, it provides a consistent and repeatable set of tests, ensuring that previously tested functionality remains intact.
How would you differentiate between a heuristic evaluation in usability testing and standard user interface testing?
- Method of Analysis
- Test Execution Speed
- Tools Used
- Type of Defects Detected
Heuristic evaluation and standard user interface testing differ mainly in their method of analysis. A heuristic evaluation is a usability inspection method where evaluators, usually usability experts, compare a software product against a set of usability principles or heuristics. In contrast, standard UI testing is often scenario-based.
What is the primary purpose of developing test scripts in automation testing?
- To document test cases
- To execute tests repeatedly without manual intervention
- To find all software defects
- To reproduce user actions
The primary purpose of developing test scripts in automation testing is to enable the execution of tests repeatedly without manual intervention. This ensures consistent test execution, efficient regression testing, and helps in validating application functionality across different test cycles.
