// In this case, this test tries to change its process user id to a
|
|
// non-superuser user so that the test that checks for write access to a
|
|
// read-only file can be more meaningful.
|
|
//
|
|
// The change of user id is done after creating the fixtures files for the same
|
|
// reason: the test may be run as the superuser within a directory in which
|
|
// only the superuser can create files, and thus it may need superuser
|
|
// privileges to create them.
|
|
//
|
|
// There's not really any point in resetting the process' user id to 0 after
|
|
// changing it to 'nobody', since in the case that the test runs without
|
|
// superuser privilege, it is not possible to change its process user id to
|
|
// superuser.
|
|
//
|
|
// It can prevent the test from removing files created before the change of user
|
|
// id, but that's fine. In this case, it is the responsibility of the
|
|
// continuous integration platform to take care of that.
