# This file contains tests for the tclBasic.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
# assocd.test, cmdInfo.test, eval.test, expr.test, interp.test,
# and trace.test.
#
# Sourcing this file into Tcl runs the tests and generates output for
# errors. No output means no errors were found.
