ProBat Testing (TLPP)

This skill covers ProBat, the native unit/functional/integration testing engine of tlppCore, used exclusively with TLPP (.tlpp) source files -- even when the code under test is legacy .prw. It covers the required #include "tlpp-probat.th", the test.<module> namespace convention, the full annotation set (@TestFixture, @Test, @Setup, @TearDown, @OneTimeSetUp, @OneTimeTearDown, @Skip, @ErrorLog), the tlpp.probat assertion functions, the class-based execution lifecycle, and SKIPASSERT for conditional assertion skipping.

Activate this skill when the user wants to create a new ProBat test fixture, add test methods to cover a routine, set up setup/teardown logic, or understand how ProBat discovers and executes tests (via REST API or the VSCode extension). Concrete test-writing templates live in the sibling patterns file.

It does not cover generating the production TLPP code being tested (see advpl-code-generation), reviewing code quality outside of tests (see advpl-code-review), or writing embedded SQL used inside test fixtures (see embedded-sql).
