Can't run a test from the vendor directory

[CedCannes]

First, I have no problem with all classes in my project, I love the comfort of using the plugin.
But... 😄 When I wanted to run a test of an atoum class from the vendor directory of my project and I got this message.

Error running tests: Cannot run program "/home/www/myproject/vendor/atoum/atoum/vendor/bin/atoum" (in directory "/home/www/myproject/vendor/atoum/atoum"): error=2, Aucun fichier ou dossier de ce type

Then I wanted to try from the cloned repository of atoum.

Error running tests: Cannot run program "/home/cedric/repos/atoum/vendor/bin/atoum" (in directory "/home/cedric/repos/atoum"): error=2, Aucun fichier ou dossier de ce type
