Pre-requisites

Before you can start performing App automation testing with Appium, you would need to follow these steps:

• Install the latest stable Python build from the official website.
• Make sure pip is installed in your system. You can install pip from here.

Clone The Sample Project

Clone the LambdaTest’s 🔗 LT-appium-python-behave repository and navigate to the code directory as shown below:

git clone https://github.com/LambdaTest/LT-appium-python-behave
cd LT-appium-python-behave

Setting Up Your Authentication

Make sure you have your LambdaTest credentials with you to run test automation scripts on LambdaTest. To obtain your access credentials, purchase a plan or access the Automation Dashboard.

Set LambdaTest Username and Access Key in environment variables.

For Linux/macOS:

export LT_USERNAME="YOUR_LAMBDATEST_USERNAME" \
export LT_ACCESS_KEY="YOUR_LAMBDATEST_ACCESS_KEY"

For Windows:

set LT_USERNAME="YOUR_LAMBDATEST_USERNAME" `
set LT_ACCESS_KEY="YOUR_LAMBDATEST_ACCESS_KEY"

Upload Your Application

Upload your iOS application (.ipa file) or android application (.apk file) to the LambdaTest servers using our REST API. You need to provide your Username and AccessKey in the format Username:AccessKey in the cURL command for authentication. Make sure to add the path of the appFile in the cURL request. Here is an example cURL request to upload your app using our REST API:

Using App File:

For Linux/macOS:

curl -u "YOUR_LAMBDATEST_USERNAME:YOUR_LAMBDATEST_ACCESS_KEY" \
--location --request POST 'https://manual-api.lambdatest.com/app/upload/realDevice' \
--form 'name="Android_App"' \
--form 'appFile=@"/Users/macuser/Downloads/proverbial_android.apk"'

For Windows:

curl -u "YOUR_LAMBDATEST_USERNAME:YOUR_LAMBDATEST_ACCESS_KEY" -X POST "https://manual-api.lambdatest.com/app/upload/realDevice" -F "appFile=@"/Users/macuser/Downloads/proverbial_android.apk""

Using App URL:

Linux/macOS:

curl -u "YOUR_LAMBDATEST_USERNAME:YOUR_LAMBDATEST_ACCESS_KEY" \
--location --request POST 'https://manual-api.lambdatest.com/app/upload/realDevice' \
--form 'name="Android_App"' \
--form 'url="https://prod-mobile-artefacts.lambdatest.com/assets/docs/proverbial_android.apk"'

For Windows:

curl -u "YOUR_LAMBDATEST_USERNAME:YOUR_LAMBDATEST_ACCESS_KEY" -X POST "https://manual-api.lambdatest.com/app/upload/realDevice" -d "{"url":"https://prod-mobile-artefacts.lambdatest.com/assets/docs/proverbial_android.apk","name":"sample.apk"}"

Tip:

• If you do not have any .apk or .ipa file, you can run your sample tests on LambdaTest by using our sample 🔗 Android app or sample 🔗 iOS app.
• Response of above cURL will be a JSON object containing the App URL of the format - lt://APP123456789123456789 and will be used in the next step.

Run Your First Test

Once you are done with the above-mentioned steps, you can initiate your first Behave test on LambdaTest.

Test Scenario: Check out Android.py file to view the sample test script for android and iOS.py for iOS.

Configuring Your Test Capabilities

You need to update your capabilities in appConfig.py files. In this sample project, we have provided the examples for running tests on both Android and iOS apps. We are passing platform name, platform version, device name and app url (generated earlier) along with other capabilities like build name and test name via capabilities object. The capabilities object in the sample code for a single test are defined as:

app_ios_desired_caps = {
    "deviceName":"iPhone 12",
    "platformName":"ios",
    "platformVersion":"14",
    "build":"Python Behave - iOS",
    "name":"Sample Test iOS",
    "isRealMobile":True,
    "network":True,
    "visual":True,
    "video":True,
    "app":"lt://" #Enter app_url here
}

app_android_desired_caps = {
    "deviceName":"Galaxy S20",
    "platformName":"Android",
    "platformVersion":"10",
    "build":"Python Behave - Android",
    "name":"Sample Test Android",
    "isRealMobile":True,
    "network":True,
    "visual":True,
    "video":True,
    "app":"lt://" #Enter app_url here
}

Info Note:

• You must add the generated APP_URL to the "app" capability in the config file.
• You can generate capabilities for your test requirements with the help of our inbuilt 🔗 Capabilities Generator tool. A more Detailed Capability Guide is available here 📄 .

Executing The Tests

Install the required dependencies using the following command:

pip3 install -r requirements.txt

Execute the following command to run your test on LambdaTest platform:

Android:

behave --tags @androidApp

IOS:

behave --tags @iosApp

Info: Your test results would be displayed on the test console (or command-line interface if you are using terminal/cmd) and on the 🔗 LambdaTest App Automation Dashboard.
