[Python] Skip all the test instead of decorating each test function with @pytest.mark.skipif()?

I have a pytest file which requires environment being set. So I add the following decorator on every function.

@pytest.mark.skipif('password' not in os.environ,
reason='Environment variable "password" not set.')
def test_1(mock):
....

@pytest.mark.skipif('password' not in os.environ,
reason='Environment variable "password" not set.')
def test_2(mock):
....

@pytest.mark.skipif('password' not in os.environ,
reason='Environment variable "password" not set.')
def test_3(mock):
....


Is it a way to skip all the test instead of decorating each test function?

BTW, it just skip the tests with the following message. Is it a way to display a warning information of missing environment variable?
