Q: What is sanity testing?
A: Sanity testing is a cursory testing; it is performed whenever a cursory testing is sufficient to prove the application is functioning according to specifications. This level of testing is a subset of regression testing. It normally includes a set of core tests of basic GUI functionality to demonstrate connectivity to the database, application servers, printers, etc. Q: What is performance testing? A: Performance testing verifies loads, volumes and response times, as defined by requirements. Although performance testing is a part of system testing, it can be regarded as a distinct level of testing. Q: What is load testing? A: Load testing is testing an application under heavy loads, such as the testing of a web site under a range of loads to determine at what point the system response time will degrade or fail. Q: What is installation testing? A: Installation testing is the testing of a full, partial, or upgrade install/uninstall process. The installation test is conducted with the objective of demonstrating production readiness. This test includes the inventory of configuration items, performed by the application's System Administration, the evaluation of data readiness, and dynamic tests focused on basic system functionality. Following installation testing, a sanity test is performed when necessary. Q: What is security/penetration testing? A: Security/penetration testing is testing how well the system is protected against unauthorized internal or external access, or willful damage. This type of testing usually requires sophisticated testing techniques. Q: What is recovery/error testing? A: Recovery/error testing is testing how well a system recovers from crashes, hardware failures, or other catastrophic problems. |
