Tests

Test infrastructure

Building the tests

TODO cmake call

TODO how GoogleTest it is automatically checked

adding a test

TODO create file, add to cmake lists et cetera

Writing a test case

Basic rules

• test the publicly specified interfaces
• remember to test const/non-const versions
• remember to test rvalue/lvalue versions
• try to use generalized typed test whenever possible
• write typed tests for your concepts and include all types that fulfill the concept

Test dependencies

• prefer many small tests to one big test
• try to make tests atomic, i.e. make them independent of functionality tested in other tests
• if you need to use functionality from other tests, re-order your tests so that they only depend on previously tested functionality, not on things tested "later on"
• never introduce circular dependencies between tests!
