配置 Pytest 发现以忽略类名 [英] Configure Pytest discovery to ignore class name

问题描述

Pytest 的默认发现规则将导入所有以 Test 开头且没有 __init__() 的类.我有一种情况，这会导致导入错误的类.

Pytest's default discovery rules will import all Class starting with Test that do not have an __init__(). I have a situation where this causes an incorrect class to be imported.

我正在测试一个使用 Factory Boy 的 django 项目.http://factoryboy.readthedocs.org/en/latest/ 构建 Django 模型名为 Testimonial.

I am testing a django project that uses Factory Boy. http://factoryboy.readthedocs.org/en/latest/ to build out a Django model named Testimonial.

像这样:

class TestimonialFactory(factory.Factory):
    class Meta:
        model = models.Testimonial

这个问题是 factory.Factory 没有 __init__().所以 py.test 看到 Testimonials 并尝试运行.这反过来又会尝试在 pytest 发现阶段将记录插入到数据库中(随之而来的是欢笑和失败).

This issue is that factory.Factory does not have an __init__(). So py.test sees Testimonials and tries to run. Which in turn tries to insert a record into the database within the pytest discovery phase (hilarity and failures ensue).

我通过更改 pytest.ini 来查找测试类以从 Check 而不是 Test 开始，从而破解了一种解决方法:

I have hacked a workaround by changing the pytest.ini to look for Test classes to start with Check instead of Test:

[pytest]
python_classes=Check

这不是我真正想要的.有没有办法明确告诉 py.test 忽略某个名称的测试?

This is not really what I want. Is there any way to explicitly tell py.test to ignore a test of a certain name?

推荐答案

这是我使用的一个简单的解决方案，但有一些开销.

Here is a simple solution that I use, but has some overhead.

class DisablePyTestCollectionMixin(object):
  __test__ = False

class TestimonialFactory(DisablePyTestCollectionMixin):
  pass
