lsp-test is a functional testing framework for Language Server Protocol servers.
```haskell
-import Language.Haskell.LSP.Test
+import Language.LSP.Test
main = runSession "hie" fullCaps "proj/dir" $ do
doc <- openDoc "Foo.hs" "haskell"
skipMany anyNotification
```
Try out the example tests in the `example` directory with `cabal test`.
-For more examples check the [Wiki](https://github.com/bubba/lsp-test/wiki/Introduction).
+For more examples check the [Wiki](https://github.com/bubba/lsp-test/wiki/Introduction), or see this [introductory blog post](https://lukelau.me/haskell/posts/lsp-test/).
Whilst writing your tests you may want to debug them to see what's going wrong.
You can set the `logMessages` and `logStdErr` options in `SessionConfig` to see what the server is up to.
There are also corresponding environment variables so you can turn them on from the command line:
```
-LSP_TEST_LOG_MESSAGES=1 cabal test
+LSP_TEST_LOG_MESSAGES=1 LSP_TEST_LOG_STDERR=1 cabal test
```
