The sources in this directory are unit test cases. Boost includes a |
|||
unit testing framework, and since bitcoin already uses boost, it makes |
|||
sense to simply use this framework rather than require developers to |
|||
configure some other framework (we want as few impediments to creating |
|||
unit tests as possible). |
|||
|
|||
The build system is setup to compile an executable called "test_bitcoin" |
|||
that runs all of the unit tests. The main source file is called |
|||
test_bitcoin.cpp, which simply includes other files that contain the |
|||
actual unit tests (outside of a couple required preprocessor |
|||
directives). The pattern is to create one test file for each class or |
|||
source file for which you want to create unit tests. The file naming |
|||
convention is "<source_filename>_tests.cpp" and such files should wrap |
|||
their tests in a test suite called "<source_filename>_tests". For an |
|||
examples of this pattern, examine uint160_tests.cpp and |
|||
uint256_tests.cpp. |
|||

For further reading, I found the following website to be helpful in |
|||
explaining how the boost unit test framework works: |
