Their job is to concentrate 10on tricky features that caused bugs in the past to detect regression. 11 12This test runs very basic features, like registering things in cache, 13writing tree, etc. 14 15Note that this test *deliberately* hard-codes many expected object 16IDs. When object ID computation changes, like in the previous case of 17swapping compression and hashing order, the person who is making the 18modification *should* take notice and update the test vectors here. 19' 20 21################################################################ 22# It appears that people try to run tests without building... 23 24../git >/dev/null 25iftest $? !=1 26then 27echo>&2'You do not seem to have built git yet.' 28exit1 29fi 30 31. ./test-lib.sh 32 33################################################################ 34# git init has been done in an empty repository. 35# make sure it is empty. 36 37test_expect_success '.git/objects should be empty after git init in an empty repo'' 38 find .git/objects -type f -print >should-be-empty && 39 test_line_count = 0 should-be-empty 40' 41 42# also it should have 2 subdirectories; no fan-out anymore, pack, and info. 43# 3 is counting "objects" itself 44test_expect_success '.git/objects should have 3 subdirectories'' 45 find .git/objects -type d -print >full-of-directories && 46 test_line_count = 3 full-of-directories 47' 48 49################################################################ 50# Test harness 51test_expect_success 'success is reported like this'' 52 : 53' 54test_expect_failure 'pretend we have a known breakage'' 55 false 56' 57 58run_sub_test_lib_test () { 59 name="$1" descr="$2"# stdin is the body of the test code 60mkdir"$name"&& 61( 62cd"$name"&& 63cat>"$name.sh"<<-EOF && 64 #!$SHELL_PATH 65 66 test_description='$descr(run in sub test-lib) 67 68 This is run in a sub test-lib so that we do not get incorrect 69 passing metrics 70 ' 71 72 # Point to the t/test-lib.sh, which isn't in ../ as usual 73 .
