- # This file contains tests for the tclVar.c source file. Tests appear in
- # the same order as the C code that they test. The set of tests is
- # currently incomplete since it currently includes only new tests for
- # code changed for the addition of Tcl namespaces. Other variable-
- # related tests appear in several other test files including
- # namespace.test, set.test, trace.test, and upvar.test.
- #
- # Sourcing this file into Tcl runs the tests and generates output for
- # errors. No output means no errors were found.
