How to run any of the console OpenServer?

need to run unit Codeception test
The manual says that to run so
./vendor/bin/codecept run
but it produces
"." is not internal or external
command, operable program or batch file.

if you run php through the console, it says
dir=$(d=${0%[/\\]*}; cd "$d"; cd "../codeception/base" && pwd)
