The testsuite "Datetime string parsing by format (detailed)" tests parsing of a string with various conversion specifications. However, `tostring(dt)` is used as a test oracle, and all these testcases do not test some conversion specifications at all because the metamethod `__tostring` for the datetime object uses `:format()` with the default format string. Due to missed tests for conversion specifications, the behavior described in #10470 was missed: ``` tarantool> dt = date.parse('Mon', {format = '%a'}) tarantool> dt --- - 1970-01-01T00:00:00Z ... tarantool> dt:format('%a') --- - Thu ... ``` The patch adds tests for `strptime` with all possible conversion specifications described in strftime(3) [1][2]. 1. https://man.freebsd.org/cgi/man.cgi?strftime(3) 2. https://pubs.opengroup.org/onlinepubs/009695399/functions/strptime.html Follows up #8588 Follows up #6731 Relates to #10470 NO_CHANGELOG=testing NO_DOC=testing (cherry picked from commit 109b18df4da0b34f4408f67902e0db04540cb32b)

The tests `array.test.lua` and `map.test.lua` require the remote Tarantool instance for running testcases. When tests are executed by test-run.py, it runs this Tarantool instance. The testcases that require the remote instance were ported to luatest to make tests able to run with ctest. The testcases `builtins-13.1` and `builtins-14.1` are companion testcases and were moved as well. Required by patches for CTest support, because allows to execute aforementioned tests without test-run.py.

The patch set a path to `tarantool` executable binary explicitly in the aforementioned test. NO_CHANGELOG=codehealth NO_DOC=codehealth (cherry picked from commit 7844e6034bd67f3e5a57710443373da5200e441a)

The test gh_5747_crash_multiple_args_test.lua uses a `tarantool` binary that is available in a current PATH environment variable. In some cases, PATH may point to a system `tarantool` executable and this could be unexpected for those who run the test. The patch set a path to `tarantool` executable derived from a command-line used to run the test.

According to CMake policy CMP0110 whitespaces and other special characters are forbidden before CMake 3.19. This policy is triggered with the patch for CTest support and breaks test generation: NO_WRAP The following name given to add_test() is invalid if CMP0110 is not set or set to OLD: `test/box-luatest/gh_7217_repeatable_{in, up}sert_memtx_tx_conflict_test.lua´ NO_WRAP The patch renames file without using whitespaces and special characters. Required for CTest support.
