如何測試與tasty-quickcheck monadicIO屬性?我嘗試了以下方法,其中testCase
按預期工作(來自HUnit),但testProperty
(來自QuickCheck)未編譯。如何使用tasty-quickcheck檢查monadic IO屬性?
import Test.Common
import Models.Client as Client
import Foundation
import Test.Foundation.Types()
import Test.QuickCheck.Monadic as QCM
import Opaleye
import Data.Pool as P
tests :: ConnectionPool -> TestTree
tests dbPool = testGroup "All tests"
[
testProperty "Client DB" $ testClientDB dbPool
, testCase "Existing client.properties in production" $ withResource dbPool testExistingClientProperties
]
testExistingClientProperties :: Connection -> Assertion
testExistingClientProperties = undefined -- REDACTED
testClientDB :: ConnectionPool -> Property
testClientDB dbPool = monadicIO $ do
withResource dbPool $ \conn -> do
(client :: Client) <- pick arbitrary
client_ <- run $ insertModel conn client
QCM.assert (client == client_)
錯誤:
testClientDB :: ConnectionPool -> Property
testClientDB dbPool = monadicIO $ do
withResource dbPool $ \conn -> do
(client :: BloatedClient) <- pick arbitrary
client_ <- run $ insertModel conn client
QCM.assert (client == client_)
你見過Opaleye有嗎一個你可以用來獲取靈感的測試套件? https://github.com/tomjaguarpaw/haskell-opaleye/tree/master/Test –
@TomEllis你的意思是「靈感」以什麼方式?在使用QC編寫數據庫測試時,我是否做了根本性錯誤?因爲我似乎直接通過'QC.quickCheck'運行'testClientDB'。這只是它不與美味的'TestTree'構成# –
我的意思是如果你喜歡,你可以使用與Opaleye的QuickCheck測試用例相同的測試設置。這可能比試圖發現你自己的方式更容易。儘管如此,我認爲你並沒有做任何根本性的錯誤。 –
