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.
"""
# Initialize variables to track the current and maximum runs
# Placeholder for the solution
