# 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.
