标签：传参 test1 begin setup param 用例 case time print
pytest前置钩子（setup）与用例之间互相传参
- 方法一：
import pytest
import time
@pytest.fixture()
def setup(request):
begin_time = time.time()
print('param from case: %s' % request.param)
return begin_time
@pytest.mark.parametrize('setup',[1,5], indirect=True) #indirect 把setup当作函数执行
@pytest.mark.parametrize('a,b',
[(1,5),(3,4)])
def test_param(setup,a,b):
begin_time = setup
print('begin_time is: ', begin_time)
print('param_a', a)
print('param_b', b)
执行结果：

方法二：发现了cache的使用，进一步优化（如果是多个用例文件共用setup，则可以把setup添加至conftest）
import pytest
import time
@pytest.fixture()
def setup(cache, request):
begin_time = time.time()
print('param from case: %s' % request.param)
cache.set('begin_time', begin_time)
# return begin_time
yield
print('after case')
print(cache.get('a',default='haha'))
print(cache.get('b',default='haha'))
print(cache.get('my_dict',default='haha'))
@pytest.mark.parametrize('setup',[1,5], indirect=True)
@pytest.mark.parametrize('a,b',
[(1,5),(3,4)])
def test1_param(cache,setup,a,b):
begin_time = cache.get('begin_time','haha')
print('begin_time is: ', begin_time)
print('param_a', a)
print('param_b', b)
cache.set('a', a)
cache.set('b', b)
cache.set('my_dict', {1:2, 2:'heihei'})
if __name__ == '__main__':
pytest.main(['-sv', 'test1.py'])
执行结果：
