+/* Minimal scaffolding for opentracker's unit tests. No external dependencies.
+
+   Tests are grouped into modules, one per source file under test. A module is
+   a list of small case functions, each pinning one behaviour. A failing CHECK
+   reports file, line and the offending values, then returns from the case it
+   is in, so a single run reports as many independent problems as it can.
+   Because the macros return, they may only be used in functions returning
+   void. */
