3. 1. Introduction
• Testing is a lifecycle activity
• Starts with proposal software development is
made.
• For every development activity there is a
testing activity.

5. 1. Structured approach to testing
2. Activities during each phase of SDLC
3. Analyse structures produced during
development phases for adequacy and
testability
4. Generate test sets based on structures
5. Additional activities during design and coding
6. Determine that structures are consistent with
previously generated structures
7. Define and redefine test sets.
Mustufa Sir

6. 3. Testing during proposal stage
• Requirement statement development starts
from system proposal.
• The success of these approach during
proposal stage lies in defining the problem
and proposed solution.
Mustufa Sir

7. 4. Testing during requirement stage
1. Adequate
2. Clear/Unambiguous
3. Verifiable/Testable
4. Measurable
5. Feasible
6. Not conflicting with each other
Mustufa Sir

8. 5. Testing during test planning phase
1. Generate test plan to support development
activities
2. Generate test cases based on system
structure
3. Analyse requirement/design coverage
Mustufa Sir

9. 6. Testing during design phase
1. Consistency with respect to requirements
2. Analyse design for errors
3. Analyse error handling
4. Developer verify information flow and logical
structure
5. Testers inspect design in detail
Mustufa Sir

10. 7. Testing during coding phase
1. Coding standard/ Guideline implementation
2. Coding optimisation
3. Code interpreting design
4. Unit testing

13. 9. Critical roles and responsibilities
Development
• Project planning activities including
requirement elicitation, estimation, project
planning, scheduling, definition of quality
attributes required by the customer etc
• Resourcing may include identification and
organization of adequate number of people,
machines, hardware, software, tools etc
Mustufa Sir

14. Testing
• Test planning including test strategy definition,
test planning, test case writing etc
• Resourcing may include identification and
organization of adequate number of people,
machines, hardware, software, tools etc
Mustufa Sir

15. Customer
• Specifying requirements and signing off
requirement statement, designs etc
• Participating in acceptance testing as per roles
and responsibilities defined in acceptance test
plan
