2 lsp-test is a functional testing framework for Language Server Protocol servers.

7 doc <- openDoc "Foo.hs" "haskell"
8 skipMany anyNotification
9 symbols <- getDocumentSymbols doc
14 ### Unit tests with HSpec
16 describe "diagnostics" $
17 it "report errors" $ runSession "hie" fullCaps "test/data" $ do
18 openDoc "Error.hs" "haskell"
19 [diag] <- waitForDiagnosticsSource "ghcmod"
21 diag ^. severity `shouldBe` Just DsError
22 diag ^. source `shouldBe` Just "ghcmod"
25 ### Replaying captured session
27 replaySession "hie" "test/data/renamePass"
30 ### Parsing with combinators
32 skipManyTill loggingNotification publishDiagnosticsNotification
33 count 4 (message :: Session ApplyWorkspaceEditRequest)
34 anyRequest <|> anyResponse
