-This is the functional testing framework for [haskell-ide-engine](https://github.com/haskell/haskell-ide-engine), and potentially any other Language Server Protocol server.
+# lsp-test [![Build Status](https://travis-ci.com/bubba/lsp-test.svg?branch=master)](https://travis-ci.com/bubba/lsp-test) [![Hackage](https://img.shields.io/hackage/v/lsp-test.svg)](https://hackage.haskell.org/package/lsp-test-0.1.0.0)
+lsp-test is a functional testing framework for Language Server Protocol servers.
 
 ```haskell
-runSession "session/root/dir" $ do
-  doc <- openDoc "foo.hs" "haskell"
+import Language.Haskell.LSP.Test
+runSession "hie" fullCaps "proj/dir" $ do
+  doc <- openDoc "Foo.hs" "haskell"
+  skipMany anyNotification
+  symbols <- getDocumentSymbols doc
+```
 
-  skipMany notification
+## Examples
 
-  sendRequest TextDocumentDocumentSymbol (DocumentSymbolParams doc)
+### Unit tests with HSpec
+```haskell
+describe "diagnostics" $
+  it "report errors" $ runSession "hie" fullCaps "test/data" $ do
+    openDoc "Error.hs" "haskell"
+    [diag] <- waitForDiagnosticsSource "ghcmod"
+    liftIO $ do
+      diag ^. severity `shouldBe` Just DsError
+      diag ^. source `shouldBe` Just "ghcmod"
+```
 
-  rspSymbols <- response :: DocumentSymbolsResponse
-  let (List symbols) = fromJust (rspSymbols ^. result)
+### Replaying captured session
+```haskell
+replaySession "hie" "test/data/renamePass"
 ```
+
+### Parsing with combinators
+```haskell
+skipManyTill loggingNotification publishDiagnosticsNotification
+count 4 (message :: Session ApplyWorkspaceEditRequest)
+anyRequest <|> anyResponse
+```
+
+Try out the example tests in the `example` directory with `cabal new-test`.
+For more examples check the [Wiki](https://github.com/bubba/lsp-test/wiki/Introduction)
+
+## Developing
+The tests are integration tests, so make sure you have the following language servers installed and on your PATH:
+### [haskell-ide-engine](https://github.com/haskell/haskell-ide-engine)
+- Check out a relatively recent version of the repo, or see `.travis.yml` to get the exact commit used for CI.
+- `stack install`
+### [javascript-typescript-langserver](https://github.com/sourcegraph/javascript-typescript-langserver)
+`npm i -g javascript-typescript-langserver`
+
+Then run the tests with `stack test` or `cabal new-test`.
+
+## Troubleshooting
+Seeing funny stuff when running lsp-test via stack? If your server is built upon Haskell tooling, [keep in mind that stack sets some environment variables related to GHC, and you may want to unset them.](https://github.com/alanz/haskell-ide-engine/blob/bfb16324d396da71000ef81d51acbebbdaa854ab/test/utils/TestUtils.hs#L290-L298)
