Learn how to run your Python automation testing scripts using UnitTest on the LambdaTest platform
Before you can start performing Python automation testing using UnitTest, you would need to:
- Install the latest Python build from the official website. We recommend using the latest version.
- Make sure pip is installed in your system. You can install pip from here.
- Download the latest Selenium Client and its WebDriver bindings from the official website. Latest versions of Selenium Client and WebDriver are ideal for running your automation script on LambdaTest Selenium cloud grid.
- Install virtualenv which is the recommended way to run your tests. 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.
pip install virtualenvStep 1: Clone the LambdaTest’s Python-UnitTest-Selenium repository and navigate to the code directory as shown below:
git clone https://github.com/LambdaTest/Python-UnitTest-Selenium
cd Python-UnitTest-SeleniumStep 2: Create a virtual environment in your project folder the environment name is arbitrary.
virtualenv venvStep 3: Activate the environment.
source venv/bin/activateStep 4: Install the required packages from the cloned project directory:
pip install -r requirements.txtMake sure you have your LambdaTest credentials with you to run test automation scripts. You can get these credentials from the LambdaTest Automation Dashboard or by your LambdaTest Profile.
Step 5: 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"
Test Scenario: The lambdatest_test.py sample script tests a simple to-do application with basic functionalities like mark items as done, add items in a list, calculate total pending items etc.
Step 6: 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 object in the above code are defined as:
capabilities = {
"build": "UnitTest-Selenium-Sample",
"name": "UnitTest-Selenium-Test",
"platformName": "Windows 11",
"browserName": "Chrome",
"browserVersion": "latest",
}You can generate capabilities for your test requirements with the help of our inbuilt Desired Capability Generator.
Step 7: Please execute the command below to run your tests:
nosetests lambdatest_test.pyYour test results would be displayed on the test console (or command-line interface if you are using terminal/cmd) and on LambdaTest automation dashboard. LambdaTest Automation Dashboard will help you view all your text logs, screenshots and video recording for your entire automation tests.
You can test your locally hosted or privately hosted projects with LambdaTest Selenium grid using LambdaTest Tunnel. All you would have to do is set up an SSH tunnel using tunnel 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 live.
Refer our LambdaTest Tunnel documentation for more information.
Here’s how you can establish LambdaTest Tunnel.
Download the binary file of:
Open command prompt and navigate to the binary folder.
Run the following command:
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:
LT -user lambdatest@example.com -key 123456Once you are able to connect LambdaTest Tunnel successfully, you would just have to pass on tunnel capabilities in the code shown below :
Tunnel Capability
"tunnel" : true
