SUT Factors

Question 1

Factors influencing Test Automation

Answer 1

SUT Interfaces 
Third Party Software 
Levels of Intrusion 
Different SUT Architectures
Size and Complexity of SUT

Question 2

SUT Interfaces

Answer 2

option to decompose SUT and perform tests on different levels

Question 3

Levels of Intrusion

Answer 3

Depends on how the input for tests are being given , Higher level of intrusion - higher risk of failures.
Could be a simpler solution for test automation.

Question 4

Different SUT Architectures

Answer 4

Solutions will vary depending on the architecture of SUT , ex : C++ , puthon may need different solutions.
Also possible to come up with Hybrid solution to support both.

Question 5

size and Complexity of SUT

Answer 5

For simple SUT - simple solution of automation is enough. Focus not required to make it more flexible.
For large and complex SUT -TAS must be designed in such a way that is ultra flexible.

Question 6

Others - when SUT is not available

Answer 6

Can start planning for Test Automation
candidates for automation can be selected and requirements for automation can be identified.
during design and architecture development - these requirements can be considered to implement.
