  2. AveCalc • Read this exercise specification • http://selab.fbk.eu/swat/exercises/fitneese-2.ppt • Download the application Eclipse project and import in your Eclipse • (a) http://selab.fbk.eu/swat/exercises/AveCalc.zip • (b) File  Import  Archieve File + Next  … select the zip and import it • Run and Understand the AveCalc application • Understand this AveCalc specification and exercise description • Try to apply the black-box testing technique to identify test cases • Implement such test cases in Fitnesse • Run them

  3. AveCalc description • AveCalc is a “desktop application” that manages an electronic register (record book) for master students. • A student can add a new exam to the register, remove an existing exam and remove all exams. An exam has a name, a CFU (a positive number that represent the university credits) and a (optional) vote. An exam without vote is an exam not taken. The vote must be included (or equal) between 0 and 30. If the vote is >= 18 then the vote is positive, otherwise it is negative. It is possible to save the register and load it (all data or only positive exams). • AveCalc computes some statistics: average of the exams passed, total number of CFU, number of exams passed, (hypothetical) degree vote and whether the student has passed a number of exams sufficient to defend his/her thesis

  5. Populate the Database 1) Write a test case to populate the database An exam is composed of a name, CFU (i.e., a number that represent the university credit of the exam) and an optional vote.

  6. Add an Exam 2) Write a test case to add a new exam A student can add a new exam to the register. An exam is composed of a name, CFU (i.e., a number that represent the university credit of the exam) and an optional vote. The name is unique, CFU is a positive number (>=0) and the vote, if inserted, is a number included between 0 and 30 (the vote can be also 0 or 30). A vote < 18 is negative (i.e., the exam is not passed) while >= 18 is positive (i.e., the exam is passed). An exam can be inserted also without the vote; it can be inserted later. 'Laude' can be added only when the vote is 30

  7. Remove an Exam 3) Write a test case to remove an existing exam A student can remove an existing exam from the database

  8. Compute the average 4) Write a test case to compute the average of the exam vote The average is computed each time an exam is added to the register. Precisely, the average is a Weighted arithmetic mean (see http://en.wikipedia.org/wiki/Weighted_mean) where the weights are the CFU. A negative vote is not counted, that is, it is not considered in the calculation of the average

  9. Compute the number of Exams 5) Write a test case to compute the number of exams The 'the total number of exams' is updated each time an exam is added to the register. This value gives the sum of all the exams that are in the register.
