# This file contains tests for the tclExecute.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 execution-related tests appear in
# several other test files including namespace.test, basic.test, eval.test,
# for.test, etc.
#
# Sourcing this file into Tcl runs the tests and generates output for errors.
# No output means no errors were found.
