C. Regression Testing
D. Pilot Testing
Correct Answer: A
Explanation:
Explanation:
Parallel testing is the process of feeding test data into two systems – the modified system and an alternative system and comparing the result.
For CISA exam you should know below mentioned types of testing
Alpha and Beta Testing – An alpha version is early version is an early version of the application system submitted to the internal user for testing. The alpha version may not contain all the features planned for the final version. Typically, software goes to two stages testing before it consider finished. The first stage is called alpha testing is often performed only by the user within the organization developing the software. The second stage is called beta testing, a form of user acceptance testing, generally involves a limited number of external users. Beta testing is the last stage of testing, and normally involves real world exposure, sending the beta version of the product to independent beta test sites or offering it free to interested user.
Pilot Testing – A preliminary test that focuses on specific and predefined aspect of a system. It is not meant to replace other testing methods, but rather to provide a limited evaluation of the system. Proof of concept are early pilot tests – usually over interim platform and with only basic functionalities.
White box testing – Assess the effectiveness of a software program logic. Specifically, test data are used in determining procedural accuracy or conditions of a program’s specific logic path. However, testing all possible logical path in large information system is not feasible and would be cost prohibitive, and therefore is used on selective basis only.
Black Box Testing – An integrity based form of testing associated with testing components of an information system’s “functional” operating effectiveness without regards to any specific internal program structure. Applicable to integration and user acceptance testing.
Function/validation testing – It is similar to system testing but it is often used to test the functionality of the system against the detailed requirements to ensure that the software that has been built is traceable to customer requirements.
Regression Testing – The process of rerunning a portion of a test scenario or test plan to ensure that changes or corrections have not introduced new errors. The data used in regression testing should be same as original data.
Parallel Testing – This is the process of feeding test data into two systems – the modified system and an alternative system and comparing the result.
Sociability Testing – The purpose of these tests is to confirm that new or modified system can operate in its target environment without adversely impacting existing system. This should cover not only platform that will perform primary application processing and interface with other system but, in a client server and web development, changes to the desktop environment. Multiple application may run on the user’s desktop, potentially simultaneously, so it is important to test the impact of installing new dynamic link libraries (DLLs ) , making operating system registry or configuration file modification, and possibly extra memory utilization.
