This is a prototype for running tests from documentation. The test in EvalTest.kt runs the documentation tests in Sum.kt (the last test fails on purpose).

Currently, each kdoc line that starts with >>> marks an assertion that will be executed as a separate test. Only assertEquals method is currently supported for assertions.

Todo:

• Produce more relevant information on test failure (file and line number, maybe the failed expression itself).
• Support functions not in global scope (currently it cannot be used to call functions from packages).
• Make stack trace nicer.
