From d2117e9c828e02bfc1da38768fc3f6198cab9340 Mon Sep 17 00:00:00 2001 From: Mark Whitley Date: Sat, 10 Mar 2001 00:51:29 +0000 Subject: [PATCH] Created new regression testing framework with a number of testcases (many more can be added). Also changed 'test' target in makefile to run the new tester.sh. (Hopefully, we should be able to remove all the tests/*.mk files soon.) --- Makefile | 5 +- tests/testcases | 301 ++++++++++++++++++++++++++++++++++++++++++++++++ tests/tester.sh | 104 +++++++++++++++++ 3 files changed, 409 insertions(+), 1 deletion(-) create mode 100644 tests/testcases create mode 100755 tests/tester.sh diff --git a/Makefile b/Makefile index c28e621c2..c3c0f7119 100644 --- a/Makefile +++ b/Makefile @@ -317,7 +317,10 @@ loop.h: mk_loop_h.sh @ $(SHELL) $< > $@ test tests: - cd tests && $(MAKE) all + # old way of doing it + #cd tests && $(MAKE) all + # new way of doing it + cd tests && ./tester.sh clean: - cd tests && $(MAKE) clean diff --git a/tests/testcases b/tests/testcases new file mode 100644 index 000000000..1838fa0fc --- /dev/null +++ b/tests/testcases @@ -0,0 +1,301 @@ +# testcases +# +# This file should be filled with test cases to test applets that: +# +# - can somehow produce output (we can't test sync or sleep) +# - have a GNU (or other) counterpart +# - are not interactive (don't require a ^C or anything) +# - don't require extensive setup or cleanup (a litte setup is fine) +# - don't have huge and possibly damaging effects (fsck, swapoff) +# +# If possible, a test case should be made that tests each option the applet +# supports.
