From e1d94f07d191bd6797a5bd5e5e12fb7bbcfee8af Mon Sep 17 00:00:00 2001 From: Patrick Thomson Date: Thu, 13 Jun 2019 14:12:40 -0400 Subject: [PATCH] Remove Listable instance for Source. This was created with a whole mess of Leancheck combinators. A Hedgehog approach makes things easier. --- semantic-core/semantic-core.cabal | 4 +- semantic.cabal | 3 + test/Data/Functor/Listable.hs | 17 ----- test/Data/Source/Spec.hs | 111 +++++++++++++++++------------- test/Generators.hs | 12 ++++ test/Spec.hs | 1 + 6 files changed, 83 insertions(+), 65 deletions(-) create mode 100644 test/Generators.hs diff --git a/semantic-core/semantic-core.cabal b/semantic-core/semantic-core.cabal index 05cf971b2..6aac48ed6 100644 --- a/semantic-core/semantic-core.cabal +++ b/semantic-core/semantic-core.cabal @@ -71,9 +71,9 @@ test-suite spec other-modules: Generators build-depends: base , semantic-core - , hedgehog >= 0.6 && <1 + , hedgehog ^>= 1 , tasty >= 1.2 && <2 - , tasty-hedgehog >= 0.2 && <1 + , tasty-hedgehog ^>= 1.0.0.1 , tasty-hunit >= 0.10 && <1 , trifecta hs-source-dirs: test diff --git a/semantic.cabal b/semantic.cabal index 2c7f67288..9061a1b2e 100644 --- a/semantic.cabal +++ b/semantic.cabal @@ -380,14 +380,17 @@ test-suite test , Tags.Spec , SpecHelpers , Test.Hspec.LeanCheck + , Generators build-depends: semantic , tree-sitter-json , Glob ^>= 0.10.0 + , hedgehog ^>= 1 , hspec >= 2.6 && <3 , hspec-core >= 2.6 && <3 , hspec-expectations ^>= 0.8.2 , tasty ^>= 1.2.3 , tasty-golden ^>= 2.3.2 + , tasty-hedgehog ^>= 1.0.0.1 , tasty-hspec ^>= 1.1.5.1 , HUnit ^>= 1.6.0.0 , leancheck >= 0.8 && <1 diff --git a/test/Data/Functor/Listable.hs b/test/Data/Functor/Listable.hs index a5ff8e0f3..ee74ea081 100644 --- a/test/Data/Functor/Listable.hs +++ b/test/Data/Functor/Listable.hs @@ -566,20 +566,3 @@ instance Listable Pos where instance Listable Span where tiers = cons2 Span - -instance Listable Blob where - tiers = cons4 makeBlob - -instance Listable BlobPair where - tiers = liftTiers tiers - -instance Listable Source where - tiers = fromUTF8 `mapT` tiers - -instance Listable ByteString where - tiers = (T.encodeUtf8 .
