Mocha With Appium
Tutorial To Run Your First Test On LambdaTest
In this topic, you will learn how to configure and run your Mocha automation testing scripts with Appium on LambdaTest Real Device Cloud platform.
Objective
By the end of this topic, you will be able to:
- Run a sample automation script of Mocha for application testing with Appium on LambdaTest.
- Learn more about Desired Capabilities for Appium testing.
- Explore advanced features of LambdaTest.
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. View on GitHub
Pre-requisites
Before you can start performing App automation testing with Appium, please make sure:
- You have access to LambdaTest username and accessKey. If you have not registered yet, you can do the same by visiting our website. You will be able to access the credentials in the LambdaTest Profile
- Download and install NodeJS from official NodeJS website. You should be having NodeJS v6 or newer.
- Make sure you are using the latest version of JavaScript.
- Install npm from the official npm website.
Run your first test
1. 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 from System:
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""
Using App URL:
curl -u "undefined:undefined" -X POST "https://manual-api.lambdatest.com/app/upload/realDevice" -F "url=:https://prod-mobile-artefacts.lambdatest.com/assets/docs/proverbial_android.apk" -F "name=Proverbial_App"
- 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.
2. Clone the sample project
Clone the LambdaTest’s 🔗 LT-appium-nodejs-mocha repository and navigate to the code directory as shown below:
git clone https://github.com/LambdaTest/LT-appium-nodejs-mocha
cd LT-appium-nodejs-mocha
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. Then, set LambdaTest Username
and Access Key
in environment variables with following commands.
- Linux / MacOS
- Windows
export LT_USERNAME=undefined \
export LT_ACCESS_KEY=undefined
set LT_USERNAME=undefined `
set LT_ACCESS_KEY=undefined
4. Write your automation script
An automation script for the sample application available above has been provided here.
- iOS
- Android
const driver= require("appium-base-driver")
//const { default: driver } = require("appium-android-driver/build/lib/driver");
const { By } = require("selenium-webdriver");
const { element } = require("wd/lib/element-commands");
require("appium-base-driver")
var assert= require("assert"),
webdriver = require("selenium-webdriver"),
conf_file= process.argv[3] || "conf/ios.conf.js";
var caps = require("../" + conf_file).capabilities;
var buildDriver = function(caps) {
return new webdriver.Builder()
.usingServer(
"http://" +
LT_USERNAME +
":" +
LT_ACCESS_KEY +
"@mobile-hub.lambdatest.com/wd/hub"
)
.withCapabilities(caps)
.build();
};
describe("Mocha Appium iOS Test " + caps.browserName, function() {
var driver;
this.timeout(0);
it ('Application is launched', function name(done) {
driver=buildDriver(caps);
driver.findElement(By.xpath('//XCUIElementTypeButton[@name="color"]')).click().then(function(){
console.log("Successfully clicked Color");
});
driver.findElement(By.xpath('//XCUIElementTypeStaticText[@name="Notification"]')).click().then(function(){
console.log("Successfully clicked Notification");
});
driver.findElement(By.xpath('//XCUIElementTypeStaticText[@name="Toast"]')).click().then(function(){
console.log("Successfully clicked Toast");
});
driver.findElement(By.xpath('//XCUIElementTypeButton[@name="Text"]')).click().then(function(){
console.log("Successfully clicked Text");
driver.quit()
});
});
});
const { default: driver } = require("appium-android-driver/build/lib/driver");
const { By } = require("selenium-webdriver");
const { capabilities } = require("../conf/android.conf");
require("appium-android-driver")
var assert= require("assert"),
webdriver = require("selenium-webdriver"),
conf_file= process.argv[3] || "conf/Appp.conf.js";
var caps = require("../" + conf_file).capabilities;
var buildDriver = function(caps) {
return new webdriver.Builder()
.usingServer(
"http://" +
LT_USERNAME +
":" +
LT_ACCESS_KEY +
"@mobile-hub.lambdatest.com/wd/hub"
)
.withCapabilities(caps)
.build();
};
describe("Mocha Appium Test " + caps.browserName, function() {
var driver;
this.timeout(0);
it ('Application is launched', function name(done) {
driver=buildDriver(caps);
driver.findElement(By.id('com.lambdatest.proverbial:id/color')).click().then(function(){
console.log("Successfully clicked Color");
});
driver.findElement(By.id('com.lambdatest.proverbial:id/Text')).click().then(function(){
console.log("Successfully clicked Text");
});
driver.findElement(By.id('com.lambdatest.proverbial:id/notification')).click().then(function(){
console.log("Successfully clicked Notification");
})
driver.findElement(By.id('com.lambdatest.proverbial:id/toast')).click().then(function(){
console.log("Successfully clicked Toast");
driver.quit()
})
});
});
Configure the test capabilities
You can update your custom capabilities in the scripts. In our sample script, 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.Ensure to update the APP_URL
, username
and accessKey
in the code scripts before running the tests. The capabilities object in the sample code for a single test are defined as:
- Android
- iOS
LT_USERNAME = process.env.LT_USERNAME || "<your username>"; //Enter your LambdaTest username here
LT_ACCESS_KEY = process.env.LT_ACCESS_KEY || "<your accessKey>"; //Enter your LambdaTest accessKey here
exports.capabilities = {
'build': 'Mocha-Appium-Sample', //Build name
'name': 'Mocha-Android', // Test name
'platformName':'android', // OS name
'deviceName': 'Galaxy S10', // Device name
'platformVersion': '11', // OS version
'app' : 'lt://proverbial-android', // Add app (.apk) url here
'isRealMobile' : true,
'visual': false, // To take step by step screenshot
'network':false, // To capture network Logs
'console':false, // To capture console logs.
'tunnel': false // If you want to run the localhost than change it to true
};
LT_USERNAME = process.env.LT_USERNAME || "<your username>"; //Enter your LambdaTest username here
LT_ACCESS_KEY = process.env.LT_ACCESS_KEY || "<your accessKey>"; //Enter your LambdaTest accessKey here
exports.capabilities = {
'build': 'Mocha-iOS-Sample', //Build name
'name': 'Mocha-iOS', // Test name
'platformName':'ios', // OS name
'deviceName': 'iPhone 12 Pro', // Device name
'platformVersion': '15', // OS version
'app' : 'lt://proverbial-ios', // Add app (.ipa) url here
'isRealMobile' : true,
'visual': false, // To take step by step screenshot
'network':false, // To capture network Logs
'console':false, // To capture console logs.
'tunnel': false // If you want to run the localhost than change it to true
};
- 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. For more details, please refer to our guide on Desired Capabilities in Appium.
5. Execute your test case
- Execute the following commands to install the required dependencies:
npm i
npm install
npm install selenium-webdriver
npm i appium-android-driver
npm i appium-base-driver
npm install --save
- The tests can be executed in the terminal using the following command:
- Android
- iOS
npm run android //to run single test
npm run parallel_android //to run parallel tests
npm run ios //to run single test
npm run parallel_ios //to run parallel tests
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.
