[英]Testing of Conditional Statement using Pytest
When I run the test, it shows that only 1 test is passed. 当我运行测试时,它表明只有1个测试通过了。 How to the test_function so that it shows that all the tests are passed.
如何使用test_function,以显示所有测试均已通过。
Note that eval() function doesn't take any parameter. 请注意,eval()函数不带任何参数。
import pytest
def eval():
a=1 #got this value after calling some function (this can be 1,2,3 or any value)
if a ==2:
return 8
elif a == 3:
return 4
else:
return 42
@pytest.mark.parametrize("expected", [
(8),
(4),
(42),
])
def test_eval(expected):
assert eval() == expected
Okay, after clarification in the comments, that a
is a global... It would be better if it wasn't. 好吧,在评论中澄清之后,
a
是一个全局的……如果不是,那会更好。 :) :)
But if you can't change its signature, 但是,如果您不能更改其签名,
import pytest
def eval():
if a == 2:
return 8
elif a == 3:
return 4
else:
return 42
@pytest.mark.parametrize(
"input_value, expected", [(2, 8), (3, 4), (4, 42)]
)
def test_eval(input_value, expected):
global a
a = input_value
assert eval() == expected
should do the trick for you. 应该为您解决问题。
