+# Using Multiple Modules For Testing
+
+Testing a Vapor app gets tricky, and requires some maneuvering of your app targets.
+
+## **Step 1:** Update Package.swift
+
+To start, you need to split up your Vapor project into a target called `App`, and a target called `AppLogic`. The App module will only include a `main.swift`, and your `AppLogic` will contain the actual logic for the app.
+
+```swift
+import PackageDescription
+
+let package = Package(
+    name: “ProjectName”,
+    targets: [
+        Target(name: "App", dependencies: ["AppLogic"])
+    ],
+    dependencies: [
+        .Package(url: "https://github.com/vapor/vapor.git", majorVersion: 1, minor: 3)
+    ],
+    exclude: [
+        "Config",
+        "Database",
+        "Localization",
+        "Public",
+        "Resources"
+    ]
+)
+```
+
+## **Step 2:** Update Tests Folder
+
+Make sure that your tests folder has a file called `LinuxMain.swift` and a folder called `AppLogicTests`. In your `AppLogicTests`, you can add your testing files like `UserTests.swift`.
+
+As always, make sure that you regenerate with `vapor xcode -y`
