AnalystStudio (I)

Requirements engineeringRequirements engineeringRequirements engineeringRequirements engineering

• Rational RequisitePro requirements mangmt (traceability)

relational database + MS Word + Web• Rational ClearCase LT configuration management for code, web

content, visual models & requirements• Rational ClearQuest tracking change requests, linking requests

to requirements, ClearQuest Web.

AnalystStudio (II)

Requirements engineeringRequirements engineeringRequirements engineeringRequirements engineering

• Rational Rose UML (Professional Data Modeler Edition)• Rational SoDA generator of project reports; co-operates

with RequisitePro, ClearQuest, .. MS Word templates

• Rational Synchronizer automatically creates items (e.g. a use

case diagram in Rose) from other items.

DevelopmentStudio (I)

Design and codingDesign and codingDesign and codingDesign and coding

• Rational Rose UML (Enterprise Edition), forward eng.

(generating code from models to VB, VC++, ANSI C++, Java, IBM Visual Age for Java), reverse eng. (code models)

• Rational Requisite Web a Web interface to RequisitePro database• Rational Synchronizer interactions modelled in Rose diagrams

RequisitePro requirements database.

DevelopmentStudio (II)

Design and codingDesign and codingDesign and codingDesign and coding

• Rational ClearQuest• Rational ClearCase LT source code, binaries, documentation,

test suites, libraries, user-defined objects; can be used from MS Visual Studio, MS Word, Visual Age for Java, ..

• Rational SoDA• Rational Purify checks C++ and Java components for

runtime errors and memory leaks.

DevelopmentStudio (III)

Design and codingDesign and codingDesign and codingDesign and coding

• Rational PureCoverage Has that line of code been executed?• Rational Quantify detects performance bottlenecks; where

the application is spending its time• Rational TestManager How many tests have been planned,

implemented, and run? How many passed/failed? Which requirements or Rose diagrams have been covered?

TestStudio (I)

System testingSystem testingSystem testingSystem testing

• Rational RequisiteWeb• Rational SoDA• Rational PureCoverage• Rational Quantify• Rational Purify• Rational TestManager (artefact, test asset) When artefact changes, you will

automatically be prompted to re-evaluate the related test asset.

J. Nawrocki, Requirements Eng., Lecture 10

TestStudio (II)

System testingSystem testingSystem testingSystem testing

• Rational Robot recording a test and playing it back;

reporting a failure: test ID, type of failure, place of occurrence, input.

• Rational TestFactory Generates test scripts that exercise the

maximum amount of code using the least number of steps. TestRobot can rerun TestFactory scripts.

• Rational ClearQuest / ClearQuest Web

J. Nawrocki, Requirements Eng., Lecture 10

TestStudio (III)

System testingSystem testingSystem testingSystem testing

• Rational LoadTest runs multi-user performance tests

for e-business, multi-tier, and database applications; simulates conditions when there are thousands of users.

Unified Change Management

Project managementProject managementProject managementProject management

• Request Management ClearQuest generates charts and reports

e.g. on the number of unassigned defects, the defect workload of each team member; the number of bugs fixed per month, ..

• Configuration Management ClearCase LT: version & release mangmnt• Project status and measurement SoDA generates project reports.

SummarySummarySummarySummary

Rational Suite strongly supports CMM level 2 Key Process Areas.

Reviews are left behind Rational Suite.

Rational Suite does not have any support for Statistical Process Control (CMM level 4).
