||||
2. **Tor Integration**: Requires manual Tor setup (TorSharp package unavailable)
|
||||
3. **Compilation Warnings**: Some nullable reference warnings
|
||||
4. **Missing Integration**: Full Telegram bot integration tests require live bot

||||
Name = faker.Name.FullName(),
|
||||
Address = faker.Address.StreetAddress(),
|
||||
City = faker.Address.City(),
|
||||
PostCode = faker.Address.ZipCode(),
|
||||
Country = faker.PickRandom(countries)
|
||||
};
|
||||
```
|
||||
|
||||
### Random Product Selection
|
||||

|
||||
var itemCount = _random.Next(1, 6);
|
||||
var products = _products
|
||||
.OrderBy(x => _random.Next())
|
||||
.Take(itemCount);
|
||||
