pcb has two testing frameworks:

  * [[pcb:unit_tests | Unit Tests]] \\ The first uses the [[https://developer.gnome.org/glib/stable/glib-Testing.html| glib testing framework]] to execute function and object low-level tests of the code directly. These tests are generally contained by the files defining the code to be tested.
  * Application tests \\ The second uses the meager scriptability of pcb to test functions at a higher level. These tests are contained in the tests/ directory of the source tree, and are run using the run_tests.sh script.

====To Do List====
===Geometry Tests===
All of the geometry functions need tests. 
I've been trying to compile a list of functions that need tests. Many of these are indirectly tested through the [[pcb:drc| DRC tests]], but that isn't really as thorough as it ought to be.
