+# Integration Tests
+
+This directory contains integration tests for GraphQL.js across different environments and bundlers, testing basic GraphQL.JS functionality, as well as development mode and production mode behavior.
+
+Tests are run via the main integration test suite in `resources/integration-test.ts`.
+
+## Test Structure
+
+### Basic GraphQL.JS Functionality Tests
+
+Each subdirectory represents a different environment/bundler:
+
+- `node` - tests for supported Node.js versions
+- `ts` - tests for supported Typescript versions
+- `webpack` - tests for Webpack
+
+### Verifying Development Mode Tests
+
+Each subdirectory represents a different environment/bundler demonstrating enabling development mode by setting the environment variable `NODE_ENV` to `development`.
+
+### Verifying Production Mode Tests
+
+Each subdirectory represents a different environment/bundler demonstrating production mode when development mode is not enabled.
