How do I implement bpf_prog_test_run with BPF CO-RE?

Hello.
It seems like before bpf_prog_test_run is called, you need to call
bpf_prog_load. But in BPF CO-RE program, we already have
<program>_bpf__open and <program>_bpf__load which basically does the
same thing. My code look approximately like this:

-----test1_load.c---------------
#include <cgreen/cgreen.h>

Ensure(Load, load_test){
    /* should I call bpf_prog_load here? */
    bpf_prog_test_run(/* parameters */);
    /* what about bpf_object__close? */
}

TestSuite *load_tests() {
    TestSuite *suite = create_test_suite();
    return suite;
}

-----bpf_firewall.bpf.c---------
 #include "vmlinux.h"
 #include <bpf/bpf_helpers.h>

SEC("xdp_prog")
int xdp_prog_main(struct xdp_md *ctx){
    /* main program */
}

 char LICENSE[] SEC("license") = "GPL";

------bpf_firewall.c---------------
#include <cgreen/cgreen.h>
#include <bpf/libbpf.h>
#include <bpf/bpf.h>
#include "bpf_firewall.skel.h"

TestSuite *load_tests();

int main(int argc, char **argv) {
    struct bpf_firewall_bpf *obj;
    int err = 0;

    obj = bpf_firewall_bpf__open();

    err = bpf_firewall_bpf__load(obj);

    err = bpf_firewall_bpf__attach(obj);

    TestSuite *suite = create_test_suite();
    add_suite(suite, load_tests());
    run_test_suite(suite, create_text_reporter());

    bpf_firewall_bpf__destroy(obj);
    return 0;
}

How do I implement bpf_prog_test_run with BPF CO-RE?
