What is the difference between system testing and integration testing?
System testing evaluates the complete and integrated software system to ensure it meets specified requirements, focusing on the overall functionality and performance. In contrast, integration testing verifies the interactions between individual components or modules to identify interface defects.
What are the main objectives of system testing?
The main objectives of system testing are to validate the complete and integrated software system, ensure it meets specified requirements, identify defects, and verify the overall performance, security, and usability of the application before it goes into production.
What are the different types of system testing?
The different types of system testing include functional testing, non-functional testing, regression testing, performance testing, load testing, stress testing, security testing, usability testing, and compatibility testing. Each type focuses on specific aspects of the system's performance, functionality, and user experience.
What tools are commonly used for system testing?
Common tools for system testing include Selenium for automated web testing, JUnit for unit testing in Java applications, LoadRunner for performance testing, and TestComplete for functional testing. Other notable tools are QTP (Quick Test Professional), Apache JMeter for load testing, and SoapUI for API testing.
What are the common challenges faced during system testing?
Common challenges during system testing include managing complex test environments, ensuring comprehensive test coverage, dealing with tight deadlines, and coordinating with multiple teams for integration testing. Additionally, identifying and replicating defects can be difficult due to environment variability and system interdependencies.
