Confusing test coverage numbers for conditionals

[mjbvz]

Testing #24160

I added some always false conditionals and am confused by the numbers being listed for coverage. Here's the code:

def increment(x):
    """Increment x by 1, but not above 10."""
    return x + 1

def decrement(x):
    """Decrement x by 1, but not below 0."""
    if False:
        return x - 1
    if False:
        return x - 1
    if False:
        return x - 1
    if False:
        return x - 1
    if False:
        return x - 1
    if False:
        return x - 1
    if False:
        return x - 1

    return 0

This shows 100% coverage with zero branches

I know the code in these conditionals isn't reachable but these numbers seem misleading

This comes from coverage.py and how it works so this is an upstream issue more with coverage in general. Closing as its not something I can control
