从多次测试的参数化中获取夹具

Question

我的代码

@pytest.mark.parametrize(
("username", "password", "message"),
(
("", "", b"Username is required."),
("a", "", b"Password is required."),
("test", "test", b"already registered"),
),
)
def test_register_validate_input(client, username, password, message):
response = client.post(
"/register", data={"username": username, "password": password}
)
assert message in response.data
def test_register_delete_input(client, username, password, message):
response = client.delete(
"/register", data={"username": username, "password": password}
)
assert message in response.data

如果我运行python -m pytest，我得到

fixture 'username' not found

但是如果我移除 的block

def test_register_delete_input(client, username, password, message):
response = client.delete(
"/register", data={"username": username, "password": password}
)
assert message in response.data

test works

1. 我如何在删除测试中使用夹具?
2. 在两个测试中只有post/delete的区别。有没有一种结合的方法?

Answer 1

1. 您可以将@pytest.mark.parametrize(...)块从第一个测试复制粘贴到第二个测试，因为它只参数化了第一个测试，而不是第二个测试。或者，按照该用户的建议进行操作——从参数化的fixture中获取多个测试

2. 理论上可以结合;但是，由于您正在测试两个不同的动作(第一个post和第二个delete)，我想说最好将这两个测试分开。
