# safe-stock.test --
#
# This file contains tests for safe Tcl that were previously in the file
# safe.test, and use files and packages of stock Tcl 8.7 to perform the tests.
# These files may be changed or disappear in future revisions of Tcl, for
# example package opt will eventually be removed.
#
# The tests are replaced in safe.tcl with tests that use files provided in the
# tests directory.  Test numbering is for comparison with similar tests in
# safe.test.
#
# Sourcing this file into tcl runs the tests and generates output for errors.
# No output means no errors were found.
#
# The defunct package http 1.0 was convenient for testing package loading.
# - This file, safe-stock.test, uses packages opt and (from cookiejar)
#   tcl::idna to provide alternative tests based on stock Tcl packages.
#   - These are tests 7.1 7.2 7.4 9.11 9.13
#   - Tests 7.[124], 9.1[13] use "package require opt".
#   - Tests 9.1[13] also use "package require tcl::idna".
# - The corresponding tests in safe.test use example packages provided in
#   subdirectory auto0 of the tests directory, which are independent of any
#   changes made to the packages provided with Tcl.
