[Tarantool-patches] [PATCH luajit 3/7] test: stop using utils.selfrun in tests
Igor Munkin

Mon Feb 13 20:02:45 MSK 2023
Unfortunately, <utils.selfrun> is too complex to be maintained, so the
corresponding tests are split into two files: the test itself and the
script to be run by the test. As a result of the patch <utils.makecmd>
helper is introduced: it inherits some approaches from <utils.selfrun>,
but it's considered for more general use.
Relates to tarantool/tarantool#8252
