Project description

Py.test plugin for Click.

Build Coverage Version Python versions License


The current stable release:

pip install pytest_click


pytest-click comes with some configurable fixtures - cli_runner and isolated_cli_runner.

import click

def test_cli(cli_runner):

    def hello(name):
        click.echo('Hello %s!' % name)

    result = cli_runner.invoke(hello, ['Peter'])
    assert result.exit_code == 0
    assert result.output == 'Hello Peter!\n'
import click

def test_fixture(isolated_cli_runner):

    @click.argument('f', type=click.File())
    def cat(f):

    with open('hello.txt', 'w') as f:
        f.write('Hello World!')

    result = isolated_cli_runner.invoke(cat, ['hello.txt'])
    assert result.exit_code == 0
    assert result.output == 'Hello World!\n'

Both runners can be configured via runner_setup mark:

import pytest

@pytest.mark.runner_setup(charset='cp1251', env={'test': 1}, echo_stdin=True)
def test_runner_setup(cli_runner):

All kwargs will be passed to click.testing.CliRunner initialization.
