+## Getting Started
-## Table Of Contents
+[TestMu AI](https://www.testmuai.com/) (Formerly LambdaTest) is the world's first full-stack AI Agentic Quality Engineering platform that empowers teams to test intelligently, smarter, and ship faster. Built for scale, it offers a full-stack testing cloud with 10K+ real devices and 3,000+ browsers. With AI-native test management, MCP servers, and agent-based automation, TestMu AI supports Selenium, Appium, Playwright, and all major frameworks.

-* [Testing Locally Hosted or Privately Hosted Projects](#testing-locally-hosted-or-privately-hosted-projects)
+With TestMu AI (Formerly LambdaTest), you can run Ruby Selenium automation tests across real browsers and operating systems. This sample shows how to configure Ruby + Selenium to run on the TestMu AI cloud.
-## Pre-requisites
+- [Sign up on TestMu AI](https://www.testmuai.com/register/) (Formerly LambdaTest).
+- Follow the [TestMu AI Documentation](https://www.testmuai.com/support/docs/) for the full setup walkthrough.
-Before you can start performing Ruby automation testing with Selenium, you would need to:
+### Prerequisites
-* Install **Ruby** and **gem** on your local system. Follow these instructions to install on different operating systems.
+- Ruby (latest stable) and Bundler
+- A TestMu AI (Formerly LambdaTest) account with your username and access key
- * For **Windows**, you can download from the [official website](https://rubyinstaller.org/downloads/).
- * For **Linux** or **Ubuntu**, you can run a simple apt command like below:
- ```bash
- sudo apt-get install ruby-full
- ```
- * For **macOS**, you can run a [Homebrew](https://brew.sh/) command like this:
- ```bash
- brew install ruby
- ```
-* To run tests in parallel you will require the [parallel_tests](https://github.com/grosser/parallel_tests) gem.
-* LambdaTest binary file for running tests on your locally hosted web pages.
+### Setup
-### Installing Selenium Dependencies and Tutorial Repo
+Clone and install dependencies:
-Clone the LambdaTest’s [ruby-selenium-sample repository](https://github.com/LambdaTest/ruby-selenium-sample) and navigate to the code directory as shown below:
```bash
-git clone https://github.com/LambdaTest/ruby-selenium-sample.git
-cd ruby-selenium-sample
+git clone https://github.com/LambdaTest/ruby-selenium-sample && cd ruby-selenium-sample
+gem install bundler && bundle install
```
-Install selenium dependencies for Ruby automation testing.
-```bash
-gem install bundler
-bundle install
-```
-### Setting up Your Authentication
-Make sure you have your LambdaTest credentials with you to run test automation scripts with Jest on LambdaTest Selenium Grid. You can obtain these credentials from the [LambdaTest Automation Dashboard](https://automation.lambdatest.com/?utm_source=github&utm_medium=repo&utm_campaign=ruby-selenium-sample) or through LambdaTest Profile.
-
-Set LambdaTest Username and Access Key in environment variables.
- * For Linux/macOS:
- `export LT_USERNAME="YOUR_USERNAME" export LT_ACCESS_KEY="YOUR ACCESS KEY"`
- * For Windows:
- `set LT_USERNAME="YOUR_USERNAME" set LT_ACCESS_KEY="YOUR ACCESS KEY"`
-## Run Your First Test
+Set your credentials as environment variables.
-### Sample Test with Ruby
+**macOS / Linux:**
-**Test Scenario:** The to-do list example mentioned in the [lambdatest.rb](https://github.com/LambdaTest/ruby-selenium-sample/blob/master/todo-click-test.rb) sample file would help you to execute your automation test using Ruby.
-
-### Configuration of Your Test Capabilities
-
-In the test script, you need to update your test capabilities. In this code, we are passing browser, browser version, and operating system information, along with LambdaTest Selenium grid capabilities via capabilities object. The capabilities in the above code are defined as:
-```ruby
-caps = {
- :browserName => "chrome",
- :version => "latest",
- :platform => "windows 10",
- :geoLocation => "US",
- :name => "LambdaTest ruby google search name",
- :build => "LambdaTest ruby google search build",
- :network => false,
- :visual => false,
- :video => true,
- :console => false
- }
+```bash
+export LT_USERNAME="YOUR_USERNAME"
+export LT_ACCESS_KEY="YOUR_ACCESS_KEY"
+export LT_TUNNEL="YOUR_TUNNEL_NAME"
```
-> You can generate capabilities for your test requirements with the help of our inbuilt **[Capabilities Generator tool](https://www.lambdatest.com/capabilities-generator/?utm_source=github&utm_medium=repo&utm_campaign=ruby-selenium-sample)**.
-### Executing the Test
+**Windows:**
-To execute the test script, run the following script on terminal/cmd.
```bash
-bundle exec ruby todo-click-test.rb
+set LT_USERNAME="YOUR_USERNAME"
+set LT_ACCESS_KEY="YOUR_ACCESS_KEY"
+set LT_TUNNEL="YOUR_TUNNEL_NAME"
```
-Your test results would be displayed on the test console (or command-line interface if you are using terminal/cmd) and on [LambdaTest automation dashboard](https://automation.lambdatest.com/build/?utm_source=github&utm_medium=repo&utm_campaign=ruby-selenium-sample). LambdaTest Automation Dashboard will help you view all your text logs, screenshots and video recording for your entire automation tests.
-## Testing Locally Hosted or Privately Hosted Projects
+### Run tests
-You can test your locally hosted or privately hosted projects with [LambdaTest Selenium grid cloud](https://www.lambdatest.com/selenium-automation/?utm_source=github&utm_medium=repo&utm_campaign=ruby-selenium-sample) using LambdaTest Tunnel app. All you would have to do is set up an SSH tunnel using LambdaTest Tunnel app and pass toggle `tunnel = True` via desired capabilities. LambdaTest Tunnel establishes a secure SSH protocol based tunnel that allows you in testing your locally hosted or privately hosted pages, even before they are made live.
+```bash
+bundle exec ruby todo-click-test.rb
+```
->Refer our [LambdaTest Tunnel documentation](https://www.lambdatest.com/support/docs/testing-locally-hosted-pages/) for more information.
+View results on your TestMu AI dashboard.
-Here’s how you can establish LambdaTest Tunnel.
+### Local testing with TestMu AI Tunnel
->Download the binary file of:
->* [LambdaTest Tunnel for Windows](https://downloads.lambdatest.com/tunnel/v3/windows/64bit/LT_Windows.zip)
-* [LambdaTest Tunnel for Mac](https://downloads.lambdatest.com/tunnel/v3/mac/64bit/LT_Mac.zip)
-* [LambdaTest Tunnel for Linux](https://downloads.lambdatest.com/tunnel/v3/linux/64bit/LT_Linux.zip)
+To test locally hosted apps, set up the TestMu AI tunnel. OS-specific guides:
-Open command prompt and navigate to the binary folder.
+- [Local Testing on Windows](https://www.testmuai.com/support/docs/local-testing-for-windows/)
+- [Local Testing on macOS](https://www.testmuai.com/support/docs/local-testing-for-macos/)
+- [Local Testing on Linux](https://www.testmuai.com/support/docs/local-testing-for-linux/)
-Run the following command:
-```bash
-LT -user {user’s login email} -key {user’s access key}
-```
-So if your user name is lambdatest@example.com and key is 123456, the command would be:
-```bash
-LT -user lambdatest@example.com -key 123456
-```
-Once you are able to connect **LambdaTest Tunnel** successfully, you would just have to pass on tunnel capabilities in the code shown below :
+Add the following to your capabilities:
-**Tunnel Capability**
```ruby
-caps = {
- ...
- :tunnel => true,
- ...
- }
+:tunnel => true,
```

+As software development entered the AI era, testing had to evolve, too. We rebuilt the architecture to be AI-native from the ground up, with autonomous agents that **plan, author, execute, analyze, and optimize tests** while keeping humans in the loop. The platform integrates with your repos, CI, IDEs, and terminals, continuously learning from every code change and development signal.
+That evolution earned a new name: **TestMu AI**, built for an AI-first future of quality engineering. TestMu is not a new name for us. It is the name of our annual community conference, which has brought together 100,000+ quality engineers to discuss how AI would reshape testing, long before that became an industry norm.
-## We are here to help you :headphones:
+What started as a high-performance cloud testing platform has transformed into an AI-native, multi-agent system powering a connected, end-to-end quality layer. That evolution defined a new identity: LambdaTest evolved into TestMu AI, built for an AI-first future of quality engineering.
