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. ./test-lib.sh 22 23################################################################ 24# git init has been done in an empty repository. 25# make sure it is empty. 26 27test_expect_success '.git/objects should be empty after git init in an empty repo'' 28 find .git/objects -type f -print >should-be-empty && 29 test_line_count = 0 should-be-empty 30' 31 32# also it should have 2 subdirectories; no fan-out anymore, pack, and info. 33# 3 is counting "objects" itself 34test_expect_success '.git/objects should have 3 subdirectories'' 35 find .git/objects -type d -print >full-of-directories && 36 test_line_count = 3 full-of-directories 37' 38 39################################################################ 40# Test harness 41test_expect_success 'success is reported like this'' 42 : 43' 44test_expect_failure 'pretend we have a known breakage'' 45 false 46' 47 48run_sub_test_lib_test () { 49 name="$1" descr="$2"# stdin is the body of the test code 50mkdir"$name"&& 51( 52cd"$name"&& 53cat>"$name.sh"<<-EOF && 54 #!$SHELL_PATH 55 56 test_description='$descr(run in sub test-lib) 57 58 This is run in a sub test-lib so that we do not get incorrect 59 passing metrics 60 ' 61 62 # Point to the t/test-lib.sh, which isn't in ../ as usual 63 .
