篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了pytest文档54-Hooks函数terminal打印测试结果(pytest_report_teststatus)相关的知识,希望对你有一定的参考价值。
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%]
================================== FAILURES ===================================
D:\\test_x.py:13: AssertionError: assert 'hello' == 'hello world'
D:\\test_x.py:25: AssertionError: assert 'hello' not in 'hello world'
===================== 2 failed, 2 passed in 0.07 seconds ======================
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
collected 4 items
test_x.py √x√x [100%]
================================== FAILURES ===================================
D:\\soft\\kecheng202004\\xuexi\\test_x.py:13: AssertionError: assert 'hello' == 'hello world'
D:\\soft\\kecheng202004\\xuexi\\test_x.py:25: AssertionError: assert 'hello' not in 'hello world'
===================== 2 failed, 2 passed in 0.07 seconds ======================
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 =============================
collected 4 items
test_x.py Ex√x [100%]
=================================== ERRORS ====================================
__________________________ ERROR at setup of test_01 __________________________
E assert 1 == 2
---------------------------- Captured stdout setup ----------------------------
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
# 作者-上海悠悠 QQ交流群:717225969
# blog地址 https://www.cnblogs.com/yoyoketang/
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
>pytest test_x.py --tb=line
============================= test session starts =============================

test_x.py 0x√x [100%]

D:\\soft\\kecheng202004\\xuexi\\test_x.py:33: AssertionError: assert 'hello' not in 'hello world'
===================== 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')
