Sure, here is a test case generator for the "Soroban" problem:

```python
import random

def generate_soroban_configuration(digit):
    configurations = {
        '0': [
            "**** *",
            "*   *",
            "*****",
            "*****",
            "*****",
            "=====",
            "     "
        ],
        '1': [
            "****  ",
            "*  **",
            "*****",
            "*****",
            "*****",
            "=====",
            "     "
        ],
        '2': [
            "****  ",
            "* ** ",
            "*****",

            "     "
        ],
        '3': [
            "****  ",

            "*****",
            "*****",

            "*  **",
            "*****",
            "*****",
            "*****",
            "=====",
            " *   "
        ],
        '6': [
            "****  ",
            "*    ",
            "*****",

        ],
        '7': [
            "****  ",
            "*   *",
            "*****",

        ],
        '8': [

            "*   *",
            "*****",
            "*****",
            "*****",
            "=====",
            "   * "
        ],
        '9': [
            "****  ",
            "*   *",
            "*****",
            "*****",
            "*****",
            "=====",
            " * * "
        ],
    }
    return configurations[digit]

def generate_single_test_case():
    number_of_test_cases = random.randint(1, 1024)
    test_cases = []

    for _ in range(number_of_test_cases):
        num = str(random.randint(0, 99999)).zfill(5)
        test_cases.append(num)

    return test_cases

def tcgen():
    test_cases = generate_single_test_case()
    return test_cases

# Example of generating and printing test cases.
if __name__ == "__main__":
    test_cases = tcgen()
    for case in test_cases:
        print(case)
```

This generator function `tcgen` creates a list of test cases, each of which is a number with up to 5 digits. The `generate_soroban_configuration` function provides the configuration of soroban beads for each digit from 0 to 9. You can use these configurations to output the arrangement of soroban beads for each number in the test cases.
