## Penjelasan Tutorial 6
Pada pengerjaan Tutorial 6 ini, menggunakan `cosmic-ray` yang merupakan sebuah *library* dari Python yang digunakan untuk melakukan *mutation testing* dan menghasilkan sebuah *report* dalam bentuk file HTML. Instalasi `cosmic-ray` dilakukan dengan cara sebagai berikut.
````bash
$ pip install cosmic-ray
$ pip freeze > requirements.txt # update requirements.txt
````
Selanjutnya, dilakukan pembuatan **configuration files** yang akan digunakan oleh `cosmic-ray` dalam menjalankan *mutation testing*, file tersebut bernama `config.toml`
```toml
[cosmic-ray]
module-path = "tutorial_2/views.py"
python-version = ""
timeout = 10.0
excluded-modules = []
test-command = "/Users/izznfkhrlislm/Documents/Projects/PMPL/lab-pmpl/bin/python manage.py test tutorial_2.unit_tests"
[cosmic-ray.execution-engine]
name = "local"
[cosmic-ray.cloning]
method = "copy"
commands = []
[cosmic-ray.interceptors]
enabled = [ "spor", "pragma_no_mutate", "operators-filter",]
[cosmic-ray.operators-filter]
```
Terlihat pada configuration files diatas, saya menggunakan berkas *unit tests* Tutorial 2, dikarenakan pada tugas tutorial 6 ini diminta untuk melakukan *mutation testing* pada halaman **to-do list**, yang merupakan implementasi dari pengerjaan Tutorial 2.
Selanjutnya, dilakukan pembuatan *testing database* yang akan digunakan oleh `cosmic-ray` untuk menyimpan data-data yang dibuat dari eksekusi *unit tests* yang dibuat *mutation testing*-nya.
```bash
$ cosmic-ray init config.toml mut_test.sqlite
```
Selanjutnya, dilakukan eksekusi *mutation testing*.
```bash
$ cosmic-ray exec mut_test.sqlite
```
Setelah eksekusi *mutation testing* selesai, dilakukan *report generating* terhadap hasil *mutation testing*, dengan cara sebagai berikut.
```bash
$ cr-report mut_test.sqlite
```
Perintah tersebut menghasilkan *output* sebagai berikut.
```bash
total jobs: 21
complete: 21 (100.0%)
survival rate: 28.57%
```
**Penjelasan:** pada hasil *output* dari *report* hasil *mutation testing* tersebut, terlihat bahwa `cosmic-ray` melakukan pengujian sebanyak 21 kali terhadap 8 *unit test cases* yang terdapat dalam file `unit_tests.py` yang ada di modul Tutorial 2. Dari 21 kali pengujian, menghasilkan **survival rate** sebesar 28.57%, yang menandakan bahwa 28.57% dari keseluruhan pengujian yang dilakukan berhasil *survive*, tidak berhasil di-*kill* oleh *mutation testing*.
Berikut adalah salah satu potongan dari *report* dalam bentuk HTML yang dihasilkan.
```bash
tutorial_2/views.py start pos: (30, 22), end pos: (30, 24)
operator: core/ReplaceComparisonOperator_Eq_Lt, occurence: 0
--- mutation diff ---

def add_todo(request):
- if request.method == 'POST':
+ if request.method < 'POST':
try:
date = datetime.strptime(request.POST['date'], '%Y-%m-%dT%H:%M')
TodoList.objects.create(
worker outcome: normal, test outcome: killed
```
Pada potongan *report* tersebut, terlihat bahwa dilakukan operasi **replace comparison operator** oleh `cosmic-ray`, dengan mengubah potongan kode `if request.method == 'POST'` menjadi `if request.method < 'POST'`, dan behasil membuat *unit test* menjadi gagal, yang berarti *unit test* tersebut **strongly killed** oleh *mutation testing*.
