Action Items from Presentation I Architecture Design Test Plan Formal Requirements Specification Architecture Prototype Formal technical inspection letters Questions

Action Item(1)Verifications

- Each student has a unique test number. - No recommendation for new students - If there is a null level for a student that implies there is no

grade neither recommendation. for new students: students placement level matches their Excel sheet -->

According to the TestNo. for returning studentsplacement level matches their Excel sheet --> According to

the TestNo. and a teacher recommendation.

Action Item (2) Forms and Reports

In my project I will use Crystal Reports for Visual Studio.NET to generate reports; these reports will be printed by the clerk. My project scope covers printing students’ reports, not sending them to students by email.

Action Item (3) Generating data

ELP will give me data testing to test my program besides using generator data tool to generate random data (EMS Data Generator). The tool will generate 1000 of record for student information and their scores.

Action Item (4) COCOMO model estimates I followed these steps to estimate the cost and the size

of the my project Determine and count five information domain

characteristics: inputs, outputs, inquiries, files, and external interfaces.

Compute the Function Points following the formula: FP = UFP [0.65 + 0.01 (Fi)], which Fi are

“complexity adjustment values”. Calculate the Source Lines of Code with the help of the

AFP and the Language Factor (LF). After that I applied the COCOMO formula for the

application program.

COCOMO model estimates

The COCOMO formula for the application program: Delivered Source Instructions (KDSI) = 1.7655 K Programmer Effort (PM) = 2.4 × (KDSI) ^1.05 =

4.4 programmer-month Development Time in month (TDEV) = 2.5 ×

(PM) 0.38 = 4.4 months

Architecture Design for the client application (Clerk)

The Architecture Design for the client application is based on a two-tier architecture which contains of1- Presentation and Business Tier3- Data Tier.

C#.NET Application forms

Architecture Design for the web application (Teacher)

The Architecture Design for the web application is based on a three-tier architecture which contains of three logic tiers:

1- Presentation

2- Business

3- Data.

Test PlanType of testing

Unit testing, using NUnit testing tool.

Performance testing using JMeter tool.

Test PlanThe following items will be tested

Adding new students

Import EPT scores

Placement returning students

Formal Requirements Specification

Constraints Each student has a unique test number. No recommendation for new students If there is a null level for a student that implies there is no

grade neither recommendation. for new students: students placement level matches their Excel sheet -->

According to the TestNo. for returning studentsplacement level matches their Excel sheet --> According to

the TestNo. and a teacher recommendation.

Formal Requirements Specification (1)

Each student has a unique test number.

context Studentinv UniqueTestNo: Student.allInstances -> forAll(S1,

S2 |S1 <> S2 implies S1.TestNo <> S2.TestNo)

Formal Requirements Specification (2)

- No recommendation for new students

context s: Student

inv noRecomNewStudents:

s.status = #new implies s.recommendation -> isEmpty()

Formal Requirements Specification (3)

If there is a null level for a student that implies there is no grade neither recommendation.

context s: Studentinv nulLevelNoGradeNoRec:s.curr_level= #null implies

s.recommendation-> isEmpty() and s.grade -> isEmpty()

Formal Requirements Specification (4)

for new students: students placement level matches their Excel

sheet --According to the TestNo. for returning studentsplacement level matches their Excel sheet -->

According to the TestNo. and a teacher recommendation.

context s: Studentinv Placement :if s.status = #new and s.flagImportCurrentSeme= #yes

then lookup (s.grade)->forAll(sc|sc.l = curr_level)--not a new student else (lookup(s.grade)->forAll(sc|sc.l = curr_level) ) (if sc.l == s.placed= #curr) then (if (s.recommendation.AchivementScore >= 80) ) then ( (s.placed = #newLevel) )else (s.curr_level= #newLevel) endifendifendif
