From fe4a78d4b66f92986919b5866d4335f291db3134 Mon Sep 17 00:00:00 2001 From: Fintan Halpenny Date: Wed, 9 Aug 2017 00:19:09 +0100 Subject: [PATCH 1/8] Moved all describes tests into their own functions. Factored out the db specific tests and kept the macros as placeholders. Import everything in the cabal file for now. Only using the flags to test that everything still works. --- esqueleto.cabal | 18 +- test/Test.hs | 2822 ++++++++++++++++++++++++++--------------------- 2 files changed, 1587 insertions(+), 1253 deletions(-) diff --git a/esqueleto.cabal b/esqueleto.cabal index debe59f..815bf9d 100644 --- a/esqueleto.cabal +++ b/esqueleto.cabal @@ -107,18 +107,16 @@ test-suite test -- This library , esqueleto - if flag(postgresql) - build-depends: - postgresql-simple >= 0.2 - , postgresql-libpq >= 0.6 - , persistent-postgresql >= 2.0 + , postgresql-simple >= 0.2 + , postgresql-libpq >= 0.6 + , persistent-postgresql >= 2.0 + , mysql-simple >= 0.2.2.3 + , mysql >= 0.1.1.3 + , persistent-mysql >= 2.0 + + if flag(postgresql) cpp-options: -DWITH_POSTGRESQL if flag(mysql) - build-depends: - mysql-simple >= 0.2.2.3 - , mysql >= 0.1.1.3 - , persistent-mysql >= 2.0 - cpp-options: -DWITH_MYSQL diff --git a/test/Test.hs b/test/Test.hs index 5616f71..105e4e7 100644 --- a/test/Test.hs +++ b/test/Test.hs @@ -26,19 +26,16 @@ import Control.Monad.Trans.Reader (ReaderT) import Data.Char (toLower, toUpper) import Data.Monoid ((<>)) import Database.Esqueleto -#if defined (WITH_POSTGRESQL) import Database.Persist.Postgresql (withPostgresqlConn) import Data.Ord (comparing) import Control.Arrow ((&&&)) import qualified Database.Esqueleto.PostgreSQL as EP -#elif defined (WITH_MYSQL) import Database.Persist.MySQL ( withMySQLConn , connectHost , connectDatabase , connectUser , connectPassword , defaultConnectInfo) -#endif import Database.Persist.Sqlite (withSqliteConn) import Database.Sqlite (SqliteException) import Database.Persist.TH @@ -51,9 +48,10 @@ import qualified Data.List as L import qualified Data.Set as S import qualified Data.Text.Lazy.Builder as TLB import qualified Database.Esqueleto.Internal.Sql as EI -import Data.Time.Clock (getCurrentTime, diffUTCTime, NominalDiffTime) +import Data.Time.Clock (getCurrentTime, diffUTCTime) +------------------------------------------------------------------------------- -- Test schema share [mkPersist sqlSettings, mkMigrate "migrateAll"] [persistUpperCase| Foo @@ -133,1343 +131,1683 @@ share [mkPersist sqlSettings, mkMigrate "migrateAll"] [persistUpperCase| double Double |] + +------------------------------------------------------------------------------- + + -- | this could be achieved with S.fromList, but not all lists -- have Ord instances sameElementsAs :: Eq a => [a] -> [a] -> Bool sameElementsAs l1 l2 = null (l1 L.\\ l2) -main :: IO () -main = do - let p1 = Person "John" (Just 36) Nothing 1 - p2 = Person "Rachel" Nothing (Just 37) 2 - p3 = Person "Mike" (Just 17) Nothing 3 - p4 = Person "Livia" (Just 17) (Just 18) 4 - p5 = Person "Mitch" Nothing Nothing 5 - l1 = Lord "Cornwall" (Just 36) - l2 = Lord "Dorset" Nothing - l3 = Lord "Chester" (Just 17) +p1 :: Person +p1 = Person "John" (Just 36) Nothing 1 - hspec $ do - describe "select" $ do - it "works for a single value" $ - run $ do - ret <- select $ return $ val (3 :: Int) - liftIO $ ret `shouldBe` [ Value 3 ] +p2 :: Person +p2 = Person "Rachel" Nothing (Just 37) 2 - it "works for a pair of a single value and ()" $ - run $ do - ret <- select $ return (val (3 :: Int), ()) - liftIO $ ret `shouldBe` [ (Value 3, ()) ] +p3 :: Person +p3 = Person "Mike" (Just 17) Nothing 3 - it "works for a single ()" $ - run $ do - ret <- select $ return () - liftIO $ ret `shouldBe` [ () ] +p4 :: Person +p4 = Person "Livia" (Just 17) (Just 18) 4 - it "works for a single NULL value" $ - run $ do - ret <- select $ return nothing - liftIO $ ret `shouldBe` [ Value (Nothing :: Maybe Int) ] +p5 :: Person +p5 = Person "Mitch" Nothing Nothing 5 - describe "selectSource" $ do - it "works for a simple example" $ - run $ do - let query = selectSource $ - from $ \person -> - return person - p1e <- insert' p1 - ret <- query $$ CL.consume - liftIO $ ret `shouldBe` [ p1e ] +l1 :: Lord +l1 = Lord "Cornwall" (Just 36) - it "can run a query many times" $ - run $ do - let query = selectSource $ - from $ \person -> - return person - p1e <- insert' p1 - ret0 <- query $$ CL.consume - ret1 <- query $$ CL.consume - liftIO $ ret0 `shouldBe` [ p1e ] - liftIO $ ret1 `shouldBe` [ p1e ] +l2 :: Lord +l2 = Lord "Dorset" Nothing - it "works on repro" $ do - let selectPerson :: R.MonadResource m => String -> Source (SqlPersistT m) (Key Person) - selectPerson name = do - let source = selectSource $ from $ \person -> do - where_ $ person ^.
