-# OTUS Selenium Homework 1
+# OTUS Homework 4: Selenoid + GGR + Nginx

-## Цель проекта
-Автоматизировать 3 UI-сценария на `https://otus.ru` с использованием Selenium WebDriver 4+, JUnit 6, Guice DI, listeners, Stream API, Jsoup и обязательных проверок качества (Checkstyle + SpotBugs).
+В этом проекте я собрал инфраструктуру для запуска UI-тестов через Selenoid и добавил Ansible-деплой для локального стенда и удаленных VM.

-## Стек технологий
- Java 21
- Maven
- Selenium `4.40.0`
- WebDriverManager `6.3.3`
- JUnit `6.0.2`
- Guice `7.0.0`
- Jsoup `1.22.1`
- Guava `33.5.0-jre`
- SLF4J `2.0.17`
- Logback `1.5.31`
- Checkstyle
- SpotBugs
+## Что реализовано
+- UI-тесты из HW1 запускаются через удаленный `RemoteWebDriver` (Selenoid).
+- Поддержаны браузеры: `chrome`, `firefox`, `mobile_chrome`.
+- Подняты сервисы: `selenoid`, `selenoid-ui`, `ggr`, `nginx`.
+- Один inventory для всех стендов: `localhost` (WSL), `vm1`, `vm2`.

-## Реализованные сценарии
-1. Поиск курса по имени.
-   - Открытие каталога `https://otus.ru/catalog/courses`
-   - Поиск курса по имени через Stream API
-   - Клик по плитке курса
-   - Проверка заголовка открытого курса
+Точки доступа:
+- UI: `http://<host_ip>/`
+- WebDriver: `http://<host_ip>/wd/hub`

-2. Самые ранние/поздние курсы по дате старта.
-   - Открытие каталога `https://otus.ru/catalog/courses`
-   - Поиск ранних и поздних курсов через Stream API + `reduce`
-   - При совпадении дат проверяются все курсы с этой датой
-   - Проверка названия и даты старта на странице курса через Jsoup
+## Версии в проекте
+Настройки лежат в `ansible/inventory/group_vars/all.yml`.

-3. Случайная категория с главной страницы.
-   - Открытие `https://otus.ru`
-   - Открытие меню «Обучение»
-   - Выбор случайной категории
-   - Проверка, что открыта корректная категория
+Браузеры:
+- Chrome: `128.0`, `127.0`
+- Firefox: `125.0`, `124.0`

-## Архитектура
- 2-уровневый тест-дизайн: `tests` + `page objects`
- DI через Guice для тестов и страниц
- JUnit 6 Extension (`GuiceExtension`), без базового класса-теста
- Фабрика драйвера:
-  - `DriverFactory` (интерфейс)
-  - `ChromeDriverFactory` (реализация)
-  - `WebDriverProvider` (жизненный цикл драйвера + декоратор listener)
- Подсветка через listener:
-  - Подсветка ставится в `beforeClick`
-  - Снимается в `afterClick`
-  - Стиль элемента возвращается в исходное состояние
+Образы инфраструктуры:
+- `aerokube/selenoid:1.11.3`
+- `aerokube/selenoid-ui:1.10.11`
+- `aerokube/ggr:1.7.2`
+- `aerokube/ggr-ui:latest-release`
+- `nginx:1.28.2`

-## Структура проекта
- `src/main/java/ru/kovbasa/config` — DI-конфигурация
- `src/main/java/ru/kovbasa/driver` — фабрика и провайдер WebDriver
- `src/main/java/ru/kovbasa/listeners` — listener подсветки
- `src/main/java/ru/kovbasa/pages` — Page Object классы
- `src/main/java/ru/kovbasa/elements` — типизированные UI-элементы
- `src/test/java/ru/kovbasa/config` — JUnit extension для DI
- `src/test/java/ru/kovbasa/tests` — автотесты
+## Что нужно подготовить перед запуском
+На каждой VM должен быть пользователь `ansible`:
+- вход по SSH-ключу;
+- `sudo` без пароля (`NOPASSWD`).

-## Требования к окружению
-1. Установлен JDK 21 (доступен в `PATH`)
-2. Установлен Google Chrome
-3. Установлен Maven 3.9+
-4. Есть доступ в интернет и к `otus.ru` (тесты запускаются на живом сайте)
+Ниже один простой вариант первичной подготовки VM.

-## Запуск
-### 1. Запуск только тестов
+1. На локальной машине генерирую ключи (если их еще нет):
 ```bash
-mvn test
+ssh-keygen -f ~/.ssh/id_ed25519
 ```

-### 2. Полная проверка (тесты + Checkstyle + SpotBugs)
+2. Захожу на VM под `root`:
 ```bash
-mvn verify
+ssh root@10.10.2.127
 ```

-### 3. Запуск отдельного тестового класса
+3. Под `root` создаю пользователя `ansible`, добавляю в `sudo` и в `sudoers`:
 ```bash
-mvn "-Dtest=ru.kovbasa.tests.CourseSearchTest" test
+useradd -m -s /bin/bash ansible
+usermod -aG sudo ansible
+echo "ansible ALL=(ALL) NOPASSWD:ALL" > /etc/sudoers.d/ansible
+chmod 440 /etc/sudoers.d/ansible
 ```

-## Параметры запуска
-Пробрасываются через Maven Surefire:
- `base.url` (по умолчанию `https://otus.ru`)
- `course.name` (по умолчанию `Python Developer`)
-
-Пример переопределения:
+4. Под `root` кладу публичный ключ в профиль `ansible`:
 ```bash
-mvn "-Dcourse.name=Python Developer" test
+install -d -m 700 -o ansible -g ansible /home/ansible/.ssh
+cat >> /home/ansible/.ssh/authorized_keys
+```
+После запуска этой команды вставляю содержимое `~/.ssh/id_ed25519.pub`, затем `Ctrl+D`.
+
+5. Под `root` выставляю права:
+```bash
+chown ansible:ansible /home/ansible/.ssh/authorized_keys
+chmod 600 /home/ansible/.ssh/authorized_keys
 ```

-## Quality Gates
- Checkstyle и SpotBugs выполняется в фазе `verify`
+6. Проверяю вход под `ansible`:
+```bash
+ssh -i ~/.ssh/id_ed25519 ansible@10.10.2.127 "whoami && sudo -n true && echo sudo_ok"
+```

-## Примечания
- Тесты зависят от текущей верстки/контента `otus.ru`.
+## Как добавить новые VM
+1. Добавляю хост в `ansible/inventory/hosts.ini`.
+2. Создаю `ansible/inventory/host_vars/vmN.yml`:
+```yaml
+ansible_host: <ip>
+ansible_user: ansible
+ggr_selenoid_host_override: selenoid
+```
+
+## Запуск Ansible
+В PowerShell синтаксис `VAR=value command` не работает, поэтому запускаю через `wsl bash -lc`.
+
+Важно: `--limit` должен быть внутри кавычек команды.
+
+### localhost (WSL)
+```powershell
+wsl bash -lc "cd /mnt/c/Users/spawn/IdeaProjects/otus-autotests/homework_1/ansible && ANSIBLE_ROLES_PATH=./roles ansible-playbook -i inventory/hosts.ini playbooks/site.yml --limit localhost"
+```
+
+### VM1
+```powershell
+wsl bash -lc "cd /mnt/c/Users/spawn/IdeaProjects/otus-autotests/homework_1/ansible && ANSIBLE_ROLES_PATH=./roles ansible-playbook -i inventory/hosts.ini playbooks/site.yml --limit vm1"
+```
+
+### VM2
+```powershell
+wsl bash -lc "cd /mnt/c/Users/spawn/IdeaProjects/otus-autotests/homework_1/ansible && ANSIBLE_ROLES_PATH=./roles ansible-playbook -i inventory/hosts.ini playbooks/site.yml --limit vm2"
+```
+
+Если ключ используется из `/mnt/c/...`, в WSL может быть ошибка `UNPROTECTED PRIVATE KEY FILE`.  
+Я использую копию ключа в WSL-профиле:
+```bash
+mkdir -p ~/.ssh
+cp /mnt/c/Users/spawn/.ssh/id_ed25519 ~/.ssh/id_ed25519
+cp /mnt/c/Users/spawn/.ssh/id_ed25519.pub ~/.ssh/id_ed25519.pub
+chmod 700 ~/.ssh
+chmod 600 ~/.ssh/id_ed25519
+chmod 644 ~/.ssh/id_ed25519.pub
+```
+
+## Команды для запуска тестов
+### Все UI-тесты (Chrome)
+```bash
+mvn "-Dexecution.mode=selenoid" "-Dbrowser=chrome" "-Dbrowser.version=128.0" "-Dselenoid.url=http://10.10.2.112/wd/hub" test
+```
+
+### Конкретный UI-тест
+```bash
+mvn "-Dexecution.mode=selenoid" "-Dbrowser=chrome" "-Dbrowser.version=128.0" "-Dselenoid.url=http://10.10.2.112/wd/hub" "-Dtest=ru.kovbasa.tests.CourseSearchTest" test
+```
+
+### Mobile Chrome
+```bash
+mvn "-Dexecution.mode=selenoid" "-Dbrowser=mobile_chrome" "-Dbrowser.version=128.0" "-Dselenoid.url=http://10.10.2.112/wd/hub" test
+```
+
+### Firefox
+```bash
+mvn "-Dexecution.mode=selenoid" "-Dbrowser=firefox" "-Dbrowser.version=125.0" "-Dselenoid.url=http://10.10.2.112/wd/hub" test
+```
+
+### Citrus (HW3 API)
+Citrus: вынесен в отдельный модуль `citrus-tests`, реализовано на базе HW3;
+```bash
+mvn -f citrus-tests/pom.xml test
+```
+
+### Запуск тестов через Ansible
+```powershell
+wsl bash -lc "cd /mnt/c/Users/spawn/IdeaProjects/otus-autotests/homework_1/ansible && ANSIBLE_ROLES_PATH=./roles ansible-playbook -i inventory/hosts.ini playbooks/site.yml --limit vm1 -e run_tests_via_ansible=true"
+```
+
+## Запуск с Linux/macOS
+На Linux/macOS:
+```bash
+cd ansible
+ANSIBLE_ROLES_PATH=./roles ansible-playbook -i inventory/hosts.ini playbooks/site.yml --limit vm1
+```
