Input Space Partitioning

Question 1

What is input space partitioning?

Answer 1

Dividing a set of possible inputs into equivalence classes. Then we can test one input from each class

Question 2

What are the 3 steps to input space partitioning?

Answer 2

Identify the component being tested
Identify the possible inputs
Develop an input domain model

Question 3

An input domain model is a way to _______ possible inputs, partitioned by __________

Answer 3

describe, characteristics

Question 4

The partitions in the input space must be _______ and ______ the entire domain

Answer 4

disjoint, cover

Question 5

Care and design is required to prevent _______________ partitions (parallelograms)

Answer 5

overlapping

Question 6

Using ________ _____ can guarantee disjointness and can be automated

Answer 6

boolean partitions

Question 7

What are 2 approaches to input modelling?

Answer 7

Interface Based

Functionality/Requirements based

Question 8

What is an interface based approach to input modelling? What are some strengths?

Answer 8

Create your model based on the inputs required for a component. It’s simple and automatable

Question 9

What is an functionality based approach to input modelling? What are some strengths?

Answer 9

Derived from the expected input/output relationship by the spec. It can take more though, but could be better as it’s more goal oriented

Question 10

What are some typical characteristics?

Answer 10

Preconditions
Postconditions
Relationships to special values
Relationships between variables

Question 11

Boundary values suggest that not all values are _____, even in an equivalence class

Answer 11

equal

Question 12

We can ______ partitions to cover more behaviour

Answer 12

subdivide
