Find Maximum Run of Uppercase Characters

Write a Python function `max_run_uppercase` that takes a string as input and returns the length of the longest consecutive sequence of uppercase characters in the string.

#### Example Usage
```python [main.nopy]
print(max_run_uppercase("GeMKSForGERksISBESt"))  # Output: 5
print(max_run_uppercase("PrECIOusMOVemENTSYT"))  # Output: 6
print(max_run_uppercase("GooGLEFluTTER"))       # Output: 4
```

#### Constraints
- The input string will only contain alphabetic characters.
- The function should return `0` if there are no uppercase characters in the string.
def max_run_uppercase(test_str):
    """
    Find the maximum run of consecutive uppercase characters in the given string.

    Args:
    test_str (str): The input string.

    Returns:
    int: The length of the longest run of uppercase characters.
