在交互式会话中测试 click.prompt

Question

我想知道如何连续测试 click.prompt。

关于测试 python 点击输入提示的问题似乎集中在 . One example 集中在通过命令行给出的一个提示上。

这里github mwe我尝试测试连续提示

import click

@click.group()
@click.option('--option/--no-option', default=False)
def cli(option):
    click.echo(click.prompt('Type something'))
    # Todo later: click.echo(click.prompt('Type something else'))
    click.echo('Option is %s' % ('on' if option else 'off'))

@cli.command()
def function():
    click.echo('Functioning')

类似

import click
from click.testing import CliRunner

import cli

def test_sync():
    runner = CliRunner()
    result = runner.invoke(cli.cli, ['--debug', 'sync'], input='test')
    assert result.exit_code == 0
    assert 'Option is on' in result.output
    assert 'test' in result.output

然而失败了：

$ python -m pytest test_clickprompt.py   

    def test_sync():
        runner = CliRunner()
        result = runner.invoke(cli.cli, ['--debug', 'sync'], input='test\n')
>       assert result.exit_code == 0
E       assert 2 == 0
E        +  where 2 = <Result SystemExit(2)>.exit_code

test_clickprompt.py:9: AssertionError
======================================================= short test summary info =======================================================
FAILED test_clickprompt.py::test_sync - assert 2 == 0

正如MRBean Bremen所指出的，输入语句必须在列表之外。之后最后两个断言需要更改以进行绿色测试。

import click
from click.testing import CliRunner

import cli

def test_sync():
    runner = CliRunner()
    result = runner.invoke(cli.cli, ['--option', 'function'], input='test\ntest')
    assert result.exit_code == 0
    assert "test\ntest" in result.output
    assert "debug" not in result.output
