How can I compare two SQLAlchemy queries if they are the same?

I have a function returning SQLAlchemy query object and I want to test this function that it builds correct query.

For example:

import sqlalchemy

metadata = sqlalchemy.MetaData()
users = sqlalchemy.Table(
    "users",
    metadata,
    sqlalchemy.Column("email", sqlalchemy.String(255), nullable=False, unique=True),
    sqlalchemy.Column("username", sqlalchemy.String(50), nullable=False, unique=True),
)

def select_first_users(n):
    return users.select().limit(n)

def test_queries_are_equal(self):
    expected_query = users.select().limit(10)
    assert select_first_users(10) == expected_query  # fails here
    assert select_first_users(10).compare(expected_query)  # fails here too

I have no idea on how to compare two queries for equality. == doesn't work here because as far as I can see this objects do not have __eq__ method defined, so it compares objects by address in memory and surely fails. The compare method also does is comparison.

The only solution I see is like:

assert str(q1.compile()) == str(q2.compile())

, but is is strange and contains placeholders instead of actual values.

So how can I compare two SQLAlchemy queries for equality?

I use Python 3.7.4, SQLAlchemy==1.3.10.
