We explore the definition of functional tests in wiki pages where specific features can be present or invoked by pragmas that begin with ►.
We invoke additional tests by following a link and performing all pragmas there before continuing here.
► run Test Link to Test Page
We encourage small tests by collecting and selecting links to additional tests with specifically formatted markdown. Don't vary far from this example.
► run selected tests - [x] Test Dropping Flags - [x] Test Plugin Loading - [x] Test Link Click - [x] Test Link Resolution - [ ] Test Graphviz Node Click - [x] Observable Drill Down
► show plugins
