chapter 3 Flashcards
… is the implementation of the test strategy for a specific project
Test approach
… forms the starting point for test planning, selecting the test design techniques and test types to be employed
test approach
What are the Typical Test Approaches
- Analytical
- Model based
- methodical
- process / standard compliant
- dynamic & heuristic
- consultative
- regression averse
what factors define testing strategies
- Risks, hazards and safety
- Available resources and skills
- Test objectives
- Regulatory aspects
- The nature of the product and the business
The fundamental test process consists of the following activities …
1 Planning and Control
2 Analysis and Design
3 Implementation and Execution
4 Evaluating Exit Criteria and Reporting
5 Test Closure
Planning is influenced by …
the test policy of the organization
the scope of testing
objectives
risks
constraints
criticality
and the availability of resources
In large projects, what are some test plans test plans written for different test levels
Component test plan
Integration test plan
System test plan
Acceptance test plan
List some Test Plan Sections
Test items
Features to be tested
Features not to be tested
Approvals
Entry and exit criteria
… Defines when to start testing
Entry Criteria
… Define when to stop testing
Exit Criteria
In your requirement you want web-page response time to be 4 seconds. Therefore, when a user loads the pages, it should be loaded within maximum 4 seconds. To measure the response time accurately, you would need to rent a performance tool and you only have a budget of 500$ but you must get approval for this budget first
What is the entry criteria to start the testing ?
What is the pass criteria ?
What is the exit criteria ?
What is the suspension criteria ?
Testing would start if the budget approved
The pass criteria would be to pass the 4 seconds limit
Spend whole 500$
The server specification is not upto your expectation then you would suspend the testing
List some Test Planning Activities
- Test objectives
- Scope and risks
- What, who and how to test
- Scheduling
- Finding and assigning resources
- Test documentation
What are the Two approach for Test Estimation?
- The metrics-based approach
- The expert-based approach
… test estimation approach relies upon data collected from previous or similar projects.
The metrics-based Approach
data collected from previous or similar projects might include:
The number of :
- test conditions
- test cases written
- test cases executed
- defects found
… test estimation approach Uses the experience of owners or experts
The Expert-based Approach
experts could be:
Business experts
Test process consultants
Developers
Analysts and designers
What are Factors that Affect Estimation
- Product characteristics [ test quality, size of product, product complexity … ]
- Dev’t process characteristics [ org stability, tools used, skills … ]
- Outcome of testing [ n0. of defects … ]
In … part of the test process activity are you expected to decide on a test condition,
Analysis and Design
what is a test condition ?
- a component or system that could be verified by one or more test cases
- A function, transaction, feature …
a test condition is Located in the …
test design specification document
what is a test case ?
A set of input values, preconditions, expected results and postconditions, developed for a particular test condition
a test case is Located in the …
test case specification document
Req 1.A. The age of the employee shall be in the range from 20 to 50, whole numbers only
How do you test this test condition ?
Range 20 to 50
10 - test below range
40 - inside the range
60 - above range
Req 1.A. The age of the employee shall be in the range from 20 to 50, whole numbers only
How do you test this test condition ?
Whole Numbers
40 - accepted
30.4 - rejected
Req 1.A. The age of the employee shall be in the range from 20 to 50, whole numbers only
How do you test this test condition ?
Numbers
40 - accepted
abc - rejected
How to prioritize the test cases ? [ range, numbers, whole numbers ]
It depends on the context of the software. One of the principle testing is context dependent.
In the implementation part you are expected to …
- write a test procedure and
- write a test execution schedule.
Implementation is Located in the …
test procedure specification document
Schedule Test Procedures
1 Create Employee
2 Delete Employee
3 Update Employee
How do you prioritize them ?
1 Create Employee
2 Update Employee
3 Delete Employee
In the execution part you are expected
Run the test procedure
Log the result in the test log
Report discrepancies to the developers
