Branch coverage on continue statement

[ludaavics]

Not sure if this is a feature or a bug, but the following snippet reports 3->5 as missing coverage ...

def my_func(x):
    for i in range(10):
        if i > 3:
            print("Doing some work")
        continue


# in the test suite
import foo

def test_foo():
    bar = foo.my_func(5)

... while the following code gives 100% branch test coverage

def my_func(x):
    for i in range(10):
        if i > 3:
            print("Doing some work")
        print("Doing nothing")
        continue

I realize the example above is a bit contrived, since there is nothing after the continue, but seems like the first snippet should have full test coverage?

It seems there is something about the no-op statements, since the following also report missing coverage:

def my_func(x):
    for i in range(10):
        if i > 3:
            print("Doing some work")
        pass

This is because of coverage.py bug nedbat/coveragepy#198, which is really a Python issue. There's nothing pytest-cov can do about it.
