09 Based Testing

Question 1

When to Stop Testing?

Answer 1

Based on:
1. Resource Based Criteria
2. Activity-Based (Quality-Based) Criteria

Question 2

Resource-Based Criteria

Answer 2

Stop when you run out of money or time
Irresponsible => Quality/Other Problems

Question 3

Activity Based Criteria

Answer 3

Quality Based
Stop wehn you complete planned test activities
Directi quality measure: Reliablilty (resemble actual customer usages)
Indirect quality measure: Coverage

Question 4

Systematic Testing Checklists

Answer 4

List of items that must be systematically tested.
Each item is “checked off”
When list is complete, testing is done.

Question 5

Checklists Advantages

Answer 5

Simplicity
Increased Coverage

Question 6

Drawbacks

Answer 6

Coverage: Need to file “hole”
Duplication: Need to improve efficiency
Complex interactions not modeled.
Root cause: Complexity

Question 7

Partition Testing

Answer 7

Defining specific input variables and associated values to exercise certain parts of the program in the white-box view or to perform certain functions in the black-box view.

Question 8

Partition Testing Basic Idea

Answer 8

Coverage Across partition: Uniform
Coverage within a partition: Random

Question 9

Different Types of Partitions

Answer 9

Pure Membership based partitions
Properties/Relations used in definitions
Combinations

Question 10

Types of Activity Based Testing

Answer 10

Coverage Based
- Checklist
- Partitions

Usage-Based (Activity-Based)
- Operational Profiles (OPs)

Question 11

Operational Profiles

Answer 11

Disjoint alternatives and their associated probabilities

The # of tests runs of each operation in the OP is proportional to its probability.
