pytest文档54-Hooks函数terminal打印测试结果(pytest_report_teststatus)
前言
使用命令行执行pytest用例的时候，会在 terminal 终端打印整个用例的测试结果：
.代表通过的用例
F代表失败的用例
E代表异常的用例
如果我们不喜欢这种报告结果，可以通过 pytest_report_teststatus 钩子函数改变测试报告的内容，接下来试试吧.改成√，把F改成x，这样更直观。
pytest_report_teststatus
pytest_report_teststatus(report, config): 返回各个测试阶段的result, 可以用when属性来区分不同阶段。
when==’setup’ 用例的前置操作
when==’call’ 用例的执行
when==’teardown’ 用例的后置操作
运行案例test_x.py
import pytest

def test_01():
a = "hello"
b = "hello"
assert a == b
def test_02():
a = "hello"
b = "hello world"
assert a == b
def test_03():
a = "hello"
b = "hello world"
assert a in b
def test_04():
a = "hello"
b = "hello world"
assert a not in b
命令行执行pytest test_x.py --tb=line
>pytest test_x.py --tb=line
============================= test session starts =============================
collected 4 items
test_x.py .F.F [100%]

D:\test_x.py:25: AssertionError: assert 'hello' not in 'hello world'

运行的结果是.和F,我们希望改成√和x,在conftest.py文件写钩子函数
# conftest.py
import pytest

def pytest_report_teststatus(report, config):
'''turn . into √，turn F into x'''
if report.when == 'call' and report.failed:
return (report.outcome, 'x', 'failed')
if report.when == 'call' and report.passed:
return (report.outcome, '√', 'passed')
重新运行pytest test_x.py --tb=line
>pytest test_x.py --tb=line

关于Error异常
前面这篇https://www.cnblogs.com/yoyoketang/p/12609871.html讲到关于测试用例的执行结果,
当 setup 出现异常的时候，用例才会Error,于是可以通过report.when == 'setup’ 判断到前置操作的结果
# test_x.py
import pytest
# 作者-上海悠悠 QQ交流群:717225969
# blog地址 https://www.cnblogs.com/yoyoketang/
@pytest.fixture()
def login():
print("前置操作：准备数据")
assert 1 == 2 # 前置出现异常
yield
print("后置操作：清理数据")
def test_01(login):
a = "hello"
b = "hello"
assert a == b
def test_02():
a = "hello"
b = "hello world"
assert a == b
def test_03():
a = "hello"
b = "hello world"
assert a in b
def test_04():
a = "hello"
b = "hello world"
assert a not in b
运行结果
>pytest test_x.py --tb=line
============================= test session starts =============================

test_x.py Ex√x [100%]

前置操作：准备数据
================================== FAILURES ===================================
D:\soft\kecheng202004\xuexi\test_x.py:21: AssertionError: assert 'hello' == 'hello world'
D:\soft\kecheng202004\xuexi\test_x.py:33: AssertionError: assert 'hello' not in 'hello world'
================= 2 failed, 1 passed, 1 error in 0.09 seconds =================
当前置失败的时候，改成0
# conftest.py
import pytest

def pytest_report_teststatus(report, config):
'''turn . into √，turn F into x, turn E into 0'''
if report.when == 'call' and report.failed:
return (report.outcome, 'x', 'failed')
if report.when == 'call' and report.passed:
return (report.outcome, '√', 'passed')
if report.when == 'setup' and report.failed:
return (report.outcome, '0', 'error')
于是控制台的结果，就可以改了

===================== 3 failed, 1 passed in 0.07 seconds ======================
skip的用例可以通过report.skiped获取到,可以这样写
if report.skipped:
return (report.outcome, '/', 'skipped')
