 // Note: we are setting PATH to an empty string in tests below because on
 // POSIX systems if target binary name does not contain `/` then it is
 // searched through PATH and if it is not found anywhere in the PATH
 // but some folder in PATH is inaccessible then underlying execvp(...)
 // call will return EACCES (13) instead of ENOENT.
 // For example on some Android devices PATH would include /sbin with is
 // inaccessible - so this test will fail.
