You can't test everything. This presentation helps you choose what tests to implement so you can the most out of what you have.

1. Types of tests

2. What is the coverage of our tests?
in lines of code?
in number of test cases?
0%

3. For 100% test
coverage, you just
need infinite
resources!!!

4. We don't have
that!!!

5. do the most with

have the best cost benefit ratio
should be part of design and
development tasks
should run often
simulate interactions with other
components by the use of mocks
allow developers to simulate corner
cases

exercise the integration between
components
can test sql queries
take more time
first option when a dependency
can't be mocked
since dependencies have to be
provided, are expensive

can't see the application
tests how an actor interacts with the
app
○ it could be a person
○ or another system
corner cases should not be
implemented at this level
are great to show to a stakeholder
