问题描述

我正在为一个系统编写集成测试，该系统可以通过Web服务调用使大多数测试自动化，但是由于无法更改的遗留性，我需要手动测试人员完成一些步骤.

I am writing integration tests for a system where I can automate most of the test via web service calls, but due to legacy-ness that I cannot change, I need a few steps to be done by manual testers.

我想使用pytest并创建一个夹具，该夹具实质上会暂停测试的执行并提示控制台进行输入(例如在系统中执行XYZ；完成后键入'done'")，然后继续进行其余的测试.

I wanted to use pytest and create a fixture that essentially pauses test execution and prompts the console for input (e.g. "Do XYZ in system; type 'done' when done") and continues with the remainder of the test.

我承认我还没有对此进行大量黑客攻击，但是我从pytest文档中看到:

I admittedly haven't done a ton of hacking on this yet, but I see from pytest docs that:

除了我而言，我真的很想等待，除此之外，我的东西似乎是pytest的绝佳用例.

Except, in my case, I really do want to wait, and other than this, my stuff looks to be a great use case for pytest.

仍在互连网上搜索提示，但是如果有人已经超过了这个障碍，我很想知道.

Still searching the interwebs for hints, but if someone has gotten past this roadblock already I'd love to know.

推荐答案

从版本3开始，您可以暂时禁用捕获:

As of version 3, you can temporarily disable the capture:

def test_input(capsys):
    with capsys.disabled():
        input("hit enter to continue: ")
    print("this line is invisible as normal")
