Environment Setup

1. Global Dependencies

   • Install Python
   • Or Install Python with Homebrew

   $ brew install python
   

   • Install pip for package installation

2. LambdaTest Credentials

   • In the terminal export your LambdaTest Credentials as environmental variables:
     • For Macos & Linux

       $ export LT_USERNAME=<your LambdaTest username>
       $ export LT_ACCESS_KEY=<your LambdaTest access key>
       

     • Windows

       $ set LT_USERNAME=<your LambdaTest username>
       $ set LT_ACCESS_KEY=<your LambdaTest access key>
       

3. Project

   • The recommended way to run your tests would be in virtualenv. It will isolate the build from other setups you may have running and ensure that the tests run with the specified versions of the modules specified in the requirements.txt file.

   pip install virtualenv

   • Create a virtual environment in your project folder the environment name is arbitrary.

   virtualenv venv

   • Activate the environment:

   source venv/bin/activate

   • Install the required packages:

   pip install -r requirements.txt

Running Tests: -n option designates number of parallel tests and -s to disable output capture.

• Tests in Parallel:

  pytest -s -n 2  tests\lt_sample_todo.py

To use Pytest with LambdaTest, make sure you have the 2 environment variables LT_USERNAME and LT_ACCESS_KEY set. To obtain a username and access_key, sign up for free here).

Routing traffic through your local machine

• Set tunnel value to True in test capabilities

OS specific instructions to download and setup tunnel binary can be found at the following links.

• Windows
• Mac
• Linux

Important Note:

---

• Some Safari & IE browsers, doesn't support automatic resolution of the URL string "localhost". Therefore if you test on URLs like "http://localhost/" or "http://localhost:8080" etc, you would get an error in these browsers. A possible solution is to use "localhost.lambdatest.com" or replace the string "localhost" with machine IP address. For example if you wanted to test "http://localhost/dashboard" or, and your machine IP is 192.168.2.6 you can instead test on "http://192.168.2.6/dashboard" or "http://localhost.lambdatest.com/dashboard".
