"test_input",

"1",
"2",

],

Passes on Ubuntu 16.04, 18.04, macOS Catalina 10.15 with Python 2.7, 3.5-3.8, but for all operating systems the test name is also really long because it includes the parameterised values, which clutters the logs.
Can be worked around by splitting the long test input into its own method:
@pytest.mark.parametrize(
"test_input",
[
"1",
"2",
],
)
def test_long_input(test_input):
# Do something with test_input
pass
@pytest.mark.parametrize(
"test_input",
[
"[",
"{",
],
)
def test_long_input(test_input):
# Do something with test_input * (1024 * 1024), instead of test_input
pass
