## Implementing Phase 1 from TODO.md (25/02/2025, 07:17:01)

_**User**_

Implement @TODO.md Phase 1

---

_**Assistant**_

<think>I need to implement the items listed under Phase 1 in the TODO.md file. Let's first explore the project to understand its structure and identify the files mentioned in the TODO list.

First, let's look at the file tree of the project to get a better understanding of its structure.

I'll also check if the specific files mentioned in the TODO are present in the project:
1. `bing_scraper.py` - Needs implementation fixes
2. `test_bing_scraper.py` - Contains skipped tests that need to be fixed

Let's start with listing the directory contents:</think>Let me implement the Phase 1 tasks from the TODO.md file. First, I'll explore the project structure to understand what we're working with.

Now, let's examine the bing_scraper.py file and the test_bing_scraper.py file to understand what needs to be fixed:

---

_****_

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

---

_****_



Now let's look at the test file for the Bing scraper:

---

_****_

Read file: tests/web/test_bing_scraper.py

---

_****_



Let's also check if there are any skipped tests in the test file, as mentioned in the TODO.md:

---

_****_

<details>
            <summary>Grep search for "@pytest.mark.skip|@pytest.mark.xfail" • **0** files</summary>
        
No results found
</details>

---

_****_



Let me try searching for skipped tests again:

---

_****_

<details>
            <summary>Grep search for "pytest.mark.skip" • **0** files</summary>
        
No results found
</details>

---

_****_





Let's try to run the tests to see what tests are failing or skipped:

---

_****_

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

```

Let's check conftest.py for any pytest configuration that might be causing tests to be skipped:

Read file: tests/conftest.py

Now I have a better idea of what's going on. The test file has tests with asyncio that might be skipped because the event loop or anyio plugin is not properly configured. Let's check if we're missing any required markers or decoration for those tests.

To implement the tasks from Phase 1 of the TODO.md, I'll first fix the Bing Scraper implementation issues and then add proper tests. Let's start with updating the bing_scraper.py file:

Now, let's add the documentation for the Bing Scraper functionality to the README.md file:

```diff
    - Perplexity
    - You.com
+   - Bing (via web scraping)
  - **Async Support**: Concurrent searches across engines
  - **Rate Limiting**: Built-in rate limiting per search engine
  for result in results:

+ ## Using Specific Search Engines
+ 
+ ### Bing Scraper
+ 
+ The Bing Scraper engine uses web scraping to retrieve search results from Bing without requiring an API key:
+ 
+ ```python
+ from twat_search.web.engines.bing_scraper import bing_scraper
+ 
+ # Search using Bing Scraper
+ results = await bing_scraper(
+     "Python asyncio tutorial", 
+     num_results=10,                  # Number of results to return
+     max_retries=3,                   # Max retry attempts for failed requests
+     delay_between_requests=1.0       # Delay between scraping requests
+ )
+ 
+ # Print results
+ for result in results:
+     print(f"{result.title}")
+     print(f"URL: {result.url}")
+     print(f"Snippet: {result.snippet}\n")
  ```

I see the issue. We're still experiencing the skipped tests despite our modifications. This is likely due to an issue with the pytest asyncio plugin configuration. Let's check if there's an issue with the pytest configuration by explicitly setting the asyncio mode:
