Solved

@pytest.fixture(scope='session')
def session_browser(session_browser):
    url = "http://127.0.0.1:8000/login/"

    session_browser.visit(url)
    session_browser.fill('username', 'foobar_user')
    session_browser.fill('password', 'foobar_user')
    button = session_browser.find_by_xpath('//*[@id="sign-in"]/div[4]/input')
    button.click()

    return session_browser

def test_foobar_case1(session_browser):
        assert True

def test_foobar_case2(session_browser):
        assert True

It's easier than I thought :-) 👍
