-## Run Your First Test
-
-### Sample Test with CucumberJS
-The example mentioned below would help you to execute your **Cucumber JS** Testing automation testing-
```bash
-//nodejs-cucumber-todo/features/todo.feature
-Feature: Automate a website
- Scenario: perform click events
- When visit url "https://lambdatest.github.io/sample-todo-app"
- When field with name "First Item" is present check the box
- When field with name "Second Item" is present check the box
- When select the textbox add "Let's add new to do item" in the box
- Then click the "addbutton"
- Then I must see title "Sample page - lambdatest.com"
-```
-Now create `step definition` file.
-```js
-//nodejs-cucumber-todo/features/step_definitions/todo.js
-/*
-This file contains the code which automate the sample app.
-It reads instructions form feature file and find matching
-case and execute it.
-*/
-
-
-'use strict';
-
-const assert = require('cucumber-assert');
-const webdriver = require('selenium-webdriver');
-
-module.exports = function() {
-
- this.When(/^visit url "([^"]*)"$/, function (url, next) {
- this.driver.get('https://lambdatest.github.io/sample-todo-app').then(next);
- });
-
- this.When(/^field with name "First Item" is present check the box$/, function (next) {
- this.driver.findElement({ name: 'li1' })
- .click().then(next);
- });
-
- this.When(/^field with name "Second Item" is present check the box$/, function (next) {
- this.driver.findElement({ name: 'li3' })
- .click().then(next);
- });
-
- this.When(/^select the textbox add "([^"]*)" in the box$/, function (text, next) {
- this.driver.findElement({ id: 'sampletodotext' }).click();
- this.driver.findElement({ id: 'sampletodotext' }).sendKeys(text).then(next);
- });
-
- this.Then(/^click the "([^"]*)"$/, function (button, next) {
- this.driver.findElement({ id: button }).click().then(next);
- });
-
- this.Then(/^I must see title "([^"]*)"$/, function (titleMatch, next) {
- this.driver.getTitle()
- .then(function(title) {
- assert.equal(title, titleMatch, next, 'Expected title to be ' + titleMatch);
- });
- });
-};
-```
-Now create `cucumber js` framework `runner` file.
-```js
-//nodejs-cucumber-todo/scripts/cucumber-runner.js
-#!/usr/bin/env node
-/*
-This is parallel test runner file.
-It creates child processes equals the number of
-test environments passed.
-*/
-let child_process = require('child_process');
-let config_file = '../conf/' + (process.env.CONFIG_FILE || 'single') + '.conf.js';
-let config = require(config_file).config;
-
-process.argv[0] = 'node';
-process.argv[1] = './node_modules/.bin/cucumber-js';
-
-const getValidJson = function(jenkinsInput) {
- let json = jenkinsInput;
- json = json.replace(/\\n/g, "");
- json = json.replace('\\/g', '');
- return json;
-};
-
-let lt_browsers = null;
-if(process.env.LT_BROWSERS) {
- let jsonInput = getValidJson(process.env.LT_BROWSERS);
- lt_browsers = JSON.parse(jsonInput);
-}
-
-for( let i in (lt_browsers || config.capabilities) ){
- let env = Object.create( process.env );
- env.TASK_ID = i.toString();
- let p = child_process.spawn('/usr/bin/env', process.argv, { env: env } );
- p.stdout.pipe(process.stdout);
-}
+export LT_USERNAME="YOUR_USERNAME"
+export LT_ACCESS_KEY="YOUR_ACCESS_KEY"
```
-### Configuration of Your Test Capabilities
-In `conf/single.conf.js` file, 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:
-```js
- capabilities: [{
- browserName: 'chrome',
- platform: 'Windows 10',
- version: 'latest',
- name: "cucumber-js-single-test",
- build: "cucumber-js-LambdaTest-single"
- }]
+**Windows:**
+
+```bash
+set LT_USERNAME="YOUR_USERNAME"
+set LT_ACCESS_KEY="YOUR_ACCESS_KEY"
```
-> You can generate capabilities for your test requirements with the help of our inbuilt **[Capabilities Generator tool](https://www.lambdatest.com/capabilities-generator/?utm_source=github&utm_medium=repo&utm_campaign=NodeJs-Cucumber-Selenium)**.
-### Executing the Test
+### Run tests
-The tests can be executed in the terminal using the following command
```bash
npm run single
```
-Your test results would be displayed on the test console (or command-line interface if you are using terminal/cmd) and on [LambdaTest automation dashboard](https://automation.lambdatest.com/build/?utm_source=github&utm_medium=repo&utm_campaign=NodeJs-Cucumber-Selenium). LambdaTest Automation Dashboard will help you view all your text logs, screenshots and video recording for your entire automation tests.
-
-## Running Your Parallel Tests Using Cucumber Framework
-### Executing Parallel Tests with Cucumber
+For parallel execution:
-To run parallel tests using **CucumberJS**, we would have to execute the below command in the terminal:
```bash
npm run parallel
```
-Your test results would be displayed on the test console (or command-line interface if you are using terminal/cmd) and on [LambdaTest automation dashboard](https://automation.lambdatest.com/build/?utm_source=github&utm_medium=repo&utm_campaign=NodeJs-Cucumber-Selenium).
-## Testing Locally Hosted or Privately Hosted Projects
+View results on your TestMu AI dashboard.
-You can test your locally hosted or privately hosted projects with [LambdaTest Selenium grid cloud](https://www.lambdatest.com/selenium-automation/?utm_source=github&utm_medium=repo&utm_campaign=NodeJs-Cucumber-Selenium) using LambdaTest Tunnel app. All you would have to do is set up an SSH tunnel using LambdaTest Tunnel app 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 made live.
+### Local testing with TestMu AI Tunnel
->Refer our [LambdaTest Tunnel documentation](https://www.lambdatest.com/support/docs/testing-locally-hosted-pages/) for more information.
+To test locally hosted apps, set up the TestMu AI tunnel. OS-specific guides:
-Here’s how you can establish LambdaTest Tunnel.
+- [Local Testing on Windows](https://www.testmuai.com/support/docs/local-testing-for-windows/)
+- [Local Testing on macOS](https://www.testmuai.com/support/docs/local-testing-for-macos/)
+- [Local Testing on Linux](https://www.testmuai.com/support/docs/local-testing-for-linux/)
->Download the binary file of:
-* [LambdaTest Tunnel for Windows](https://downloads.lambdatest.com/tunnel/v3/windows/64bit/LT_Windows.zip)
-* [LambdaTest Tunnel for Mac](https://downloads.lambdatest.com/tunnel/v3/mac/64bit/LT_Mac.zip)
-* [LambdaTest Tunnel for Linux](https://downloads.lambdatest.com/tunnel/v3/linux/64bit/LT_Linux.zip)
+Add the following to your capabilities:
-Open command prompt and navigate to the binary folder.
-
-Run the following command:
-```bash
-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:
-```bash
-LT -user lambdatest@example.com -key 123456
-```
-Once you are able to connect **LambdaTest Tunnel** successfully, you would just have to pass on tunnel capabilities in the code shown below :
-
-**Tunnel Capability**
```js
-const capabilities = {
- tunnel: true,
-}
-```
-### Executing the local tests
-To run local tests using **CucumberJS**, we would have to execute the below command in the terminal:
-```bash
-npm run local
-```
-
-## Executing all the tests
-To run all the tests at once using **CucumberJS**, we would have to execute the below command in the terminal:
-
-```bash
-npm run test
+tunnel: true,
```
->If you wish to set up your CucumberJS testing through Jenkins, then refer to our [Jenkins documentation](https://www.lambdatest.com/support/docs/jenkins-with-lambdatest/?utm_source=github&utm_medium=repo&utm_campaign=NodeJs-Cucumber-Selenium).
