Testing Interview Questions And Answers
|
Q: How is testing affected by object-oriented designs?
A: A well-engineered object-oriented design can make it easier to trace from code to internal design to functional design to requirements. While there will be little affect on black box testing (where an understanding of the internal design of the application is unnecessary), white-box testing can be oriented to the application's objects. If the application was well designed this can simplify test design. Q: Why do you recommended that we test during the design phase? A: Because testing during the design phase can prevent defects later on. I recommend we verify three things... 1. Verify the design is good, efficient, compact, testable and maintainable. 2. Verify the design meets the requirements and is complete (specifies all relationships between modules, how to pass data, what happens in exceptional circumstances, starting state of each module and how to guarantee the state of each module). 3. Verify the design incorporates enough memory, I/O devices and quick enough runtime for the final product. Q: What is software quality assurance? A: Software Quality Assurance (SWQA) when Rob Davis does it is oriented to *prevention*. It involves the entire software development process. Prevention is monitoring and improving the process, making sure any agreed-upon standards and procedures are followed and ensuring problems are found and dealt with. Software Testing, when performed by Rob Davis, is also oriented to *detection*. Testing involves the operation of a system or application under controlled conditions and evaluating the results. Organizations vary considerably in how they assign responsibility for QA and testing. Sometimes they are the combined responsibility of one group or individual. Also common are project teams, which include a mix of test engineers, testers and developers who work closely together, with overall QA processes monitored by project managers. It depends on what best fits your organization's size and business structure. Rob Davis can provide QA and/or SWQA.
