pytest --doctest-modules __init__.py will only collect a single doctest because of this:

pytest/src/_pytest/main.py

Lines 768 to 781 in e986d84

# If __init__.py was the only file requested, then the matched node will be
# the corresponding Package, and the first yielded item will be the __init__
# Module itself, so just use that. If this special case isn't taken, then all
# the files in the package will be yielded.
if argpath.basename == "__init__.py":
assert isinstance(matching[0], nodes.Collector)
try:
yield next(iter(matching[0].collect()))
except StopIteration:
# The package collects nothing with only an __init__.py
# file in it, which gets ignored by the default
# "python_files" option.
pass
continue
