Pytest has the skip and skipif decorators, similar to the Python unittest module (which uses skip and skipIf), which can be found in the documentation here.

Examples from the link can be found here:

@pytest.mark.skip(reason="no way of currently testing this")
def test_the_unknown():
    ...

import sys
@pytest.mark.skipif(sys.version_info < (3,3), reason="requires python3.3")
def test_function():
    ...

The first example always skips the test, the second example allows you to conditionally skip tests (great when tests depend on the platform, executable version, or optional libraries).

For example, if I want to check if someone has the library pandas installed for a test.

@pytest.mark.skipif(
    not importlib.util.find_spec("pandas"), reason="requires the Pandas library"
)
def test_pandas_function():
    import pandas
    ...

Create a conftest.py with the following contents:

import pytest
import _pytest.skipping


def pytest_addoption(parser):
    parser.addoption(
        "--no-skips",
        action="store_true",
        default=False, help="disable skip marks")


@pytest.hookimpl(tryfirst=True)
def pytest_cmdline_preparse(config, args):
    if "--no-skips" not in args:
        return

    def no_skip(*args, **kwargs):
        return

    _pytest.skipping.skip = no_skip

the use --no-skip in command line to run all testcases even if some testcases with pytest.mark.skip decorator
