+# TestService REST client library for JavaScript
+
+
+
+**Please rely heavily on our [REST client docs](https://github.com/Azure/azure-sdk-for-js/blob/main/documentation/rest-clients.md) to use this library**
+
+Key links:
+
+- [Package (NPM)](https://www.npmjs.com/package/@msinternal/test)
+
+## Getting started
+
+### Currently supported environments
+
+- LTS versions of Node.js
+
+### Prerequisites
+
+- You must have an [Azure subscription](https://azure.microsoft.com/free/) to use this package.
+
+### Install the `@msinternal/test` package
+
+Install the TestService REST client REST client library for JavaScript with `npm`:
+
+```bash
+npm install @msinternal/test
+```
+
+### Create and authenticate a `TestServiceClient`
+
+To use an [Azure Active Directory (AAD) token credential](https://github.com/Azure/azure-sdk-for-js/blob/main/sdk/identity/identity/samples/AzureIdentityExamples.md#authenticating-with-a-pre-fetched-access-token),
+provide an instance of the desired credential type obtained from the
+[@azure/identity](https://github.com/Azure/azure-sdk-for-js/tree/main/sdk/identity/identity#credentials) library.
+
+To authenticate with AAD, you must first `npm` install [`@azure/identity`](https://www.npmjs.com/package/@azure/identity) 
+
+After setup, you can choose which type of [credential](https://github.com/Azure/azure-sdk-for-js/tree/main/sdk/identity/identity#credentials) from `@azure/identity` to use.
+As an example, [DefaultAzureCredential](https://github.com/Azure/azure-sdk-for-js/tree/main/sdk/identity/identity#defaultazurecredential)
+can be used to authenticate the client.
+
+## Troubleshooting
+
+### Logging
+
+Enabling logging may help uncover useful information about failures. In order to see a log of HTTP requests and responses, set the `AZURE_LOG_LEVEL` environment variable to `info`. Alternatively, logging can be enabled at runtime by calling `setLogLevel` in the `@azure/logger`:
+
+```ts 
+import { setLogLevel } from "@azure/logger";
+
+setLogLevel("info");
+```
+
+For more detailed instructions on how to enable logs, you can look at the [@azure/logger package docs](https://github.com/Azure/azure-sdk-for-js/tree/main/sdk/core/logger).
