# Testing
|
|
most software will contain bugs
|
|
bug severity if not always equivalent to bug priority
|
|
testing is seeking out bugs
|
|
some test types
|
|
- unit tests
|
|
- integration tests ⇒ check units work together
|
|
- end-to-end tests ⇒ check behaviour of whole program
|
|
|
|
|
|
## 1 Limitations
|
|
testing every code path is impossible
|
|
- halting problem - cant fully analyse code using code
|
|
- proved by alan turing in 1936
|
|
|
|
good test design focuses on _key cases_ to pass and fail
|
|
not probe interaction between units
|
|
- this should be done by integration testing
|
|
|
|
testing may afffect behaviour of code
|
|
- testing framework may affect the order of esecution
|
|
- testing framework may change execution speed |
