Seamless Mobile Testing With Jenkins & Selenium

Mobile apps are a big part of our lives, and ensuring they work correctly on all gadgets is critical. That’s where mobile trying out is available. It can be complex; however, it is much less tough with the proper gear.

Jenkins and Selenium are two popular tools that can help streamline this method. Jenkins handles nonstop integration, ensuring your app is usually up to date with cutting-edge adjustments. Selenium, especially when paired with Appium, facilitates automating testing on specific mobile gadgets.

This blog will show you what is jenkins and how to use Jenkins and Selenium together for seamless cellular checking out, making your improvement technique smoother and more efficient.

What Is Jenkins?

Jenkins is a broadly used open-supply DevOps tool for non-stop integration and transport. It is a Java-based software that works across specific systems. Jenkins automates walking builds from the source code repository, executing unit assessments, and sending construct reports to the relevant group individuals.

What Is Selenium?

Selenium is an extensively used open-source automation tool for checking out internet packages. Its ease of use and supportive network forums contribute to its popularity among testers. Selenium consists of four principal components: Selenium IDE, Selenium RC, Selenium WebDriver, and Selenium Grid, each serving different checking-out purposes. With features like move-browser and parallel checking out, Selenium permits testers to run their test cases across various working systems and browsers, ensuring the web software’s compatibility.

Setting Up The Environment For Mobile Testing With Jenkins & Selenium

You must set up a robust development environment to seamlessly integrate mobile testing with Jenkins and Selenium. Here’s a detailed guide covering the prerequisites, required software and tools, and the installation and configuration steps.

  • Follow the installation instructions for your operating system.
  • Start Jenkins and complete the initial setup wizard.
  • Install essential plugins like Git, NodeJS, Appium, and Selenium Grid from the Jenkins plugin manager.

Configuring Jenkins For Mobile Testing

1) Set Up Jenkins Jobs
  • Create a new job in Jenkins for your mobile testing project.
  • Configure the job to pull the source code from your version control system (e.g., GitHub).
2) Install & Configure Necessary Plugins
  • Go to `Manage Jenkins` > `Manage Plugins`.
  • Install plugins such as `Git,` `NodeJS,` `Appium,` and `Selenium Grid.`
3) Configure Build Triggers
  • Set up build triggers to automate the execution of your tests. Common triggers include webhooks from your version control system or scheduled builds.
4) Define Build Steps
  • Add build steps to run your Appium and Selenium test scripts.
  • Configure the test environment, specifying the devices or emulators to use for testing.
5) Configure Post-Build Actions
  • Set up post-build actions to generate test reports and notifications.
  • Use plugins like JUnit or Allure for detailed test reporting.
  • Configure email notifications or integrations with communication tools like Slack.

Running Your First Test

1) Write & Run Test Scripts
  • Write your mobile test scripts using Appium and Selenium.
  • Ensure the scripts are stored in your source code repository and are executable from the command line.
2) Execute Tests Via Jenkins
  • Trigger a build in Jenkins to start the test execution.
  • Monitor the build process and review the generated test reports for results and insights.

Following those steps will set up comprehensive surroundings for cell trying out with Jenkins and Selenium, ensuring clean and automated trying-out procedures in your cell applications.

Writing Mobile Test Scripts Using Selenium & Appium

Mobile test automation is essential for ensuring the first-class and reliability of cellular programs. Selenium and Appium provide a robust framework for automating mobile app checking. Here’s an in-depth manual on using those tools to jot down effective cell test scripts.

Introduction To Appium For Mobile Testing

Appium is an open-source automation device designed to try out cellular programs. It helps each Android and iOS system, allowing you to write checks using a codebase that can run on a couple of devices. Appium extends the Selenium WebDriver API, making it a widespread desire for testers familiar with Selenium.

Key Features Of Appium

Cross-Platform Testing: Write checks that work on each Android and iOS.

Language Agnostic: Supports multiple programming languages, such as Java, Python, C#, Ruby, and JavaScript.

Open Source: Free to use with a supportive community.

Real Devices and Emulators: Tests can be run on actual gadgets or emulators/simulators.

Writing A Simple Test Script For An Android/iOS Application

Below is an example of writing a simple test script using Appium and Selenium WebDriver for an Android application in Python.

**Prerequisites:**

– Install Appium server (`npm install -g appium`).

– Install Appium-Python-Client (`pip install Appium-Python-Client`).

– Android SDK and a configured Android Virtual Device (AVD) or real device.

**Example Test Script:**

“`python

from appium import webdriver

import time

# Set up desired capabilities for the Android device and app

desired_caps = {

‘platformName’: ‘Android’,

‘platformVersion’: ‘11.0’,

‘deviceName’: ’emulator-5554′,

‘app’: ‘/path/to/your/app.apk’,  # Path to the .apk file of the app

‘appPackage’: ‘com.example.yourapp’,

‘appActivity’: ‘com.example.yourapp.MainActivity’

}

# Initialize the Appium driver

driver = webdriver.Remote(‘http://localhost:4723/wd/hub’, desired_caps)

# Enter the username and password, then click the login button

username_field.send_keys(‘testuser’)

password_field.send_keys(‘password’)

login_button.click()

# Wait for some time to let the login process complete

time.sleep(5)

# Verify that the login was successful

assert driver.find_element_by_id(‘com.example.yourapp:id/welcome’).is_displayed()

# Run the test case

test_login()

# Quit the driver

driver.quit()

“`

This script demonstrates an easy login check for Android software. It initializes the Appium motive force with the desired capabilities, interacts with the app’s UI factors, and verifies that the login was a hit.

Best Practices For Writing Maintainable & Robust Test Scripts

  1. Use Page Object Model (POM): Organize your check scripts by isolating the UI elements and interactions from the actual, and take a look at common sense. This improves readability and maintainability.
  2. Descriptive Naming: Use descriptive names in your analysis strategies, variables, and instructions to make the code self-explanatory.
  3. Parameterization: Use parameterized tests to run the same test with distinctive sets of information. This facilitates testing numerous eventualities without duplicating code.
  4. Wait Strategies: Implement express and implicit waits to deal with dynamic elements and improve check reliability.
  5. Error Handling: Include sturdy blunders managing and logging to make debugging less difficult.
  6. Reusable Functions: To avoid code duplication, create reusable capabilities for everyday movements.
  7. Continuous Integration: Integrate your test scripts with CI tools like Jenkins to automate exam execution and reporting.

Leveraging LambdaTest For Enhanced Testing

LambdaTest is a cloud-based platform with an intensive go-browser and move-platform testing infrastructure. It supports Selenium and Appium, allowing you to run your tests on numerous devices and browsers.
