如何自定义pytest名称 [英] How to customize the pytest name

问题描述

我想自定义我的 pytest 的输出名称以包含我的装置名称

I would like to customize the output name of my pytest to include the name of my fixtures

所以我有

def test_t1(
    when_creating_a_project_from_a_sales_handoff,
    with_a_new_customer,
    and_no_conflicting_data_exists,
    create_project):
it_will_create_a_customer_with_the_releavant_information()
it_will_create_a_project_that_references_the_newly_created_customer()

并且我希望显示的测试名称是某个版本的

and I'd like the displayed test name to be some version of

when_creating_a_project_from_a_sales_handoff
with_a_new_customer
and_no_conflicting_data_exists
create_project

我该怎么做?我尝试创建

How can I do this? I tried creating

@fixture
def namer(request):
    request.node.name = 'test_foo'

但是没有骰子，它没有改变测试显示名称

but no dice, it didn't change the test display name

推荐答案

我设法更改了显示名称，但只能使用 pytest 私有变量.

I managed to change the displayed name, but only by using pytest private variables.

制作一个conftest.py文件并制作此功能:

Make a conftest.pyfile and make this function:

def pytest_itemcollected(item):
    """ change test name, using fixture names """
    item._nodeid = ', '.join(item._fixtureinfo.argnames)

当我用 pytest 运行这个 test_file 时:

When I run this test_file with pytest:

import pytest

@pytest.fixture()
def fixture_1():
    pass

@pytest.fixture()
def fixture_2():
    pass

def test1(fixture_1):
    assert 1 == 1

def test_a(fixture_1, fixture_2):
    assert 1 == 2

结果是:

pytest
============================= test session starts =============================

fixture_1 .                                                              [ 50%]

================================== FAILURES ===================================

fixture_1 = None, fixture_2 = None

    def test_a(fixture_1, fixture_2):

E       assert 1 == 2

test\test_so.py:15: AssertionError

新的测试名称也打印在pycharm中

The new test names are also printed in pycharm
