Appium with Pytest

In this documentation, you will learn how to trigger a automation script of Pytest for application testing with Appium on LambdaTest, set the desired capabilities for appium testing, and other advanced features of LambdaTest.

Prerequisites​

  • Your LambdaTest Username and Access key.
  • You should have Python installed.
  • Download and install pip.
  • Install pytest on your system with following pip command:
pip install pytest

Try our Sample Repository​

Step 1: Get a Sample Project​

You can use your own project to configure and test it. For demo purposes, we are using the sample repository.

Sample repo

All the code samples in this documentation can be found on LambdaTest's Github Repository. You can either download or clone the repository to quickly run your tests. Image View on GitHub

Step 2: Setup the Environment Variables​

You need to export your environment variables LT_USERNAME and LT_ACCESS_KEY that are available in your LambdaTest Profile page. Run the below mentioned commands in your terminal to setup the environment variables.

export LT_USERNAME="undefined"
export LT_ACCESS_KEY="undefined"

Step 3: Upload your Application​

Upload your iOS application (.ipa file) or android application (.apk or .aab 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. Below is an example cURL request to upload your app using our REST API:

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

  • If you do not have any .apk or .ipa file, you can run your sample tests on LambdaTest by using our sample apps, 🔗 Android app or 🔗 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

Step 4: Update your Automation Script​

An automation script for the sample application given above has been provided here. Ensure to update the APP_URL, username and accessKey in the code scripts before running the tests.

ios.py
from os import environ
import pytest
from appium import webdriver

@pytest.fixture(scope='function')
def test_setup_ios(request):
    test_name = request.node.name
    build = environ.get('BUILD', "Pytest IOS Sample")
    caps = {}
    caps["deviceName"] = "iPhone 11"
    caps["platformName"] = "iOS"
    caps["platformVersion"] = "14"
    caps["app"] = "lt://proverbial-ios"     #Enter the app (.ipa) url here
    caps["isRealMobile"] = True
    caps['build'] = build
    caps['name'] = test_name
    caps['project'] = project_name
    driver = webdriver.Remote("https://<username>:<accessKey>@mobile-hub.lambdatest.com/wd/hub", caps)   #Add LambdaTest username and accessKey here
    request.cls.driver = driver
    
    yield driver
    
    def fin():
        #browser.execute_script("lambda-status=".format(str(not request.node.rep_call.failed if "passed" else "failed").lower()))
        if request.node.rep_call.failed:
            driver.execute_script('lambda-status=failed')
        else:
            driver.execute_script('lambda-status=passed')
        driver.quit()
    request.addfinalizer(fin)
    
@pytest.hookimpl(tryfirst=True, hookwrapper=True)
def pytest_runtest_makereport(item, call):
    # this sets the result as a test attribute for LambdaTest reporting.
    # execute all other hooks to obtain the report object
    outcome = yield
    rep = outcome.get_result()

    # set an report attribute for each phase of a call, which can
    # be "setup", "call", "teardown"
    setattr(item, "rep_" + rep.when, rep)

Step 5: Configure the Test Capabilities​

You can update your custom capabilities in test scripts. In this sample project, 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 are defined as:

iOS(.ipa)
   caps = {
      "deviceName": "iPhone 11",
      "platformName": "iOS",
      "platformVersion": "14",
      "app": "lt://proverbial-ios"     # Enter the app (.ipa) URL here,
      "isRealMobile": True,
      "build": build,
      "name": test_name,
      "project": project_name
   }
info

Step 6: Execute and Monitor your Tests​

  • Install the required packages from the cloned project directory:
pip install -r requirements.txt
  • Run the following command in the directory where your project has been saved to execute your build.
pytest test_ios.py
tip

If you are unable to run the automation script with the above mentioned commands try using python -m before the given commands.

Your test results would be displayed on the test console (or CLI if you are using terminal/cmd) and on the LambdaTest App Automation Dashboard.
