如何将ctx(Context)传递给CliRunner？

Question

CliRunner列出没有参数在其文档中提供上下文.

以下内容应该是最低工作示例.真正的问题有点不同.可以通过将单击修饰函数移动到其自己的测试覆盖功能中来解决.然后点击功能几乎无用.

import click
from click.testing import CliRunner

class Config():
    def __init__(self):
        self.value = 651

@click.command()
@click.pass_context
def print_numberinfo(ctx):
    if not hasattr(ctx.obj, 'value'):
        ctx.obj = Config()
    click.echo(ctx.obj.value)

def test_print_numberinfo():
    ctx = click.Context(print_numberinfo, obj = Config())
    ctx.obj.value = 777
    runner = CliRunner()
    # how do I pass ctx to runner.invoke?
    result = runner.invoke(print_numberinfo)
    assert result.output == str(ctx.obj.value) + '\n'

您可以将Config实例作为关键字参数直接传递obj给runner.invoke：

import click
from click.testing import CliRunner

class Config():
    def __init__(self):
        self.value = 651

@click.command()
@click.pass_obj
def print_numberinfo(obj):
    if not hasattr(obj, 'value'):
        obj = Config()
    click.echo(obj.value)

def test_print_numberinfo():
    obj = Config()
    obj.value = 777
    runner = CliRunner()
    # how do I pass ctx to runner.invoke?
    result = runner.invoke(print_numberinfo, obj=obj)
    assert result.output == str(obj.value) + '\n'
