Test Point Analysis is an approach for formulating all top-down methods. TPA is utilized for arriving at the estimated effort. TPA only covers the Black-box testing which is an estimate for the test activities. It can also be useful in the case where the test hour allowance has been predetermined. Risks can clearly be identified by comparing the objective TPA estimate with the help of the number of test hours that is predetermined.
What are the different Ways of doing Black Box testing?
There are five methodologies most frequently used:
Top down according to budget
WBS (Work Breakdown Structure)
Guess and gut feeling
Early project data
TPA (Test Point Analysis)
What is Bug/Defect?
Bug: A bug is defined as an error that was found before the application goes into production. A bug gives a subliminal impression which crawled into the developer’s code quite independently of the software developer.
Defect: A defect is defined as an error that was found after the application goes into production. It presents cold harsh reality which the engineer, analyst or designer actually get something wrong.
Can you explain function points?
Function points are a unit measure for software much like an hour is to measuring time, miles are to measuring distance or Celsius is to measuring temperature. Function Points are an ordinal measure much like other measures such as kilometers, Fahrenheit, hours, so on and so forth.
This approach computes the total function points (FP) value for the project, by totaling the number of external user inputs, inquiries, outputs, and master files, and then applying the following weights: inputs (4), outputs (5), inquiries (4), and master files (10). Each FP contributor can be adjusted within a range of +/-35% for a specific project complexity.
Explain the concept of Application Boundary.
Application boundary considers users perspective. It indicates the margin between the software measured and the end user. It helps to identify what is available to the end user externally from the interface to interact with the internal of the system. This helps to identify the scope of the system.
