# 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.
