From: Junio C Hamano Date: Tue, 24 Mar 2026 18:05:09 GMT Subject: [PATCH] t6002: make test "set -e" clean Message-ID: In-Reply-To: In order to catch mistakes like misspelling "test_expect_success", we would like to eventually be able to run our test suite with the "-e" option on. We often use val=$(expr expression) only for the computation, and it is good that "expr" exits non-zero with syntactically invalid expression (it exits with 2) and other errors (with 3). "expr" however also exits with "1" if it yields 0 or null X-<. Make sure we do not fail unnecessarily under "set -e".
