@Implementing Bing Scraper Engine Continue

_**Assistant**_

<think>The user is asking me to continue with implementing the Bing Scraper Engine. Let me recall where we left off and what needs to be done next.

From the context, I see that we've already:
1. Explored the project structure to understand how search engines are implemented
2. Created `bing_scraper.py` and updated `__init__.py` to register the new engine
3. Fixed some linter errors related to imports and type annotations
4. Looked for tests but couldn't find specific ones for the new engine

I should continue with:
1. Checking if there are any remaining issues with the Bing Scraper implementation
2. Possibly creating tests for the new engine
3. Verifying that the integration is complete
4. Running any necessary validation steps

Let's start by examining the current state of the project to get a better understanding of what we've done so far.

First, let's look at the file tree to understand the project structure better:</think>I'll continue implementing the Bing Scraper engine for the twat-search package. Let's first check the project structure to understand what files we've already modified and what still needs to be done.

Let's look at our Bing Scraper implementation and make sure it's complete and properly integrated. First, let's check the content of the `bing_scraper.py` file we created:

---

_****_

Read file: src/twat_search/web/engines/bing_scraper.py

---

_****_



Let's also check the engines `__init__.py` file to make sure our engine is properly registered:

---

_****_

Read file: src/twat_search/web/engines/__init__.py

---

_****_



Great! I can see that the `bing_scraper.py` file has been properly implemented and the engine is registered in the `__init__.py` file. Now let's check if we need to add tests for our new engine.

Let's look at one of the existing test files to understand the test structure:

---

_****_

Read file: tests/web/test_webscout.py

---

_****_



Let's also check the base test file for engines to understand how the base engine testing works:

---

_****_

Read file: tests/unit/web/engines/test_base.py

---

_****_





Now let's create a test file for our Bing Scraper engine. Based on the existing tests, we'll need to create a test file that mocks the `scrape_bing` library and tests the functionality of our engine.

Let's create the test file for the Bing Scraper engine:

I need to fix the linter error in our test file. The issue is with the URL in the SearchResult mock object:

---

_****_

```diff
                  url="https://example.com",
                  snippet="Test description",
-                 source="bing-scraper",
+                 source="bing-scraper"
              )
          ]
```

---

_****_





Let me import and use the HttpUrl type from pydantic to fix the linter error:

---

_****_

```diff
  import pytest
  from unittest.mock import patch, MagicMock
+ from pydantic import HttpUrl
  
  from twat_search.web.config import EngineConfig
              SearchResult(
                  title="Test Result",
-                 url="https://example.com",
+                 url=HttpUrl("https://example.com"),
                  snippet="Test description",
-                 source="bing-scraper",
+                 source="bing-scraper"
              )
          ]
```

---

_****_





Now let's run the tests to make sure our implementation works correctly:

---

_****_

```bash
cd .. && python -m pytest tests/web/test_bing_scraper.py -v
```
