- 显示执行最慢的N个用例
- 显示所有用例的执行时间
- 显示所有耗时大于t秒的用例
(1)在test_demo.py中编写10个测试函数
import time
def test_demo01():
time.sleep(0.1)
assert 1==1
def test_demo02():
time.sleep(0.2)
assert 1==1
def test_demo03():
time.sleep(0.3)
assert 1==1
def test_demo04():
time.sleep(0.4)
assert 1==1
def test_demo05():
time.sleep(0.5)
assert 1==1
def test_demo06():
time.sleep(0.6)
assert 1==1
def test_demo07():
time.sleep(0.7)
assert 1==1
def test_demo08():
time.sleep(0.8)
assert 1==1
def test_demo09():
time.sleep(0.9)
assert 1==1
def test_demo10():
time.sleep(1.0)
assert 1==1
def test_demo11():
assert 1==1
(2) 使用命令 pytest --durations=5 执行用来显示执行最慢的5个用例

(2)细心的发现上面并没有显示所有的，test_demo11用例没有显示，这是因为pytest默认显示的耗时大于0.005秒的用例，小于0.005秒的用例默认是不显示的，如果要显示耗时小于0.005秒的用例，需要加上 -vv的参数
