# 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.
