How to test GitHub Actions Locally?

Here are different methods to Test Gitlab Locally:

Method 1. Using the GitHub Actions Toolkit

Prerequisites:

Make sure you haveNode.js and npm (Node Package Manager) installedon our local machine.

Step 1: Install the GitHub Actions Toolkit

To get, install the@ actions/corepackage from theGitHub Actions Toolkitas a evolution dependency in our project. Open our terminal or command prompt and navigate to our projection & # 8217; s root directory. Run the following bid:

npm install -- save-dev @ actions/core

This will establish the necessary packet for GitHub action test locally.

Step 2: Write a Test Script

Next, create a exam script that uses the GitHub Actions Toolkit to action and validate our workflow locally. Let & # 8217; s assume you have a GitHub Actions workflow file namedmain.workflowin our repository.

Create a file named test.js and add the undermentioned code:

const core = require (' @ actions/core '); const exec = require (' @ actions/exec '); async function run () {try {// Set the input variables (if any) core.getInput ('myInputVariable '); // Execute the measure of our workflow await exec.exec ('echo ', ['Hello, World! ']); // Add more steps as necessary // Set the output variables (if any) // Set the yield variables (if any) core.setOutput ('myOutputVariable ', 'Hello from local testing! ');} catch (error) {core.setFailed (error.message);}} run ();

• In this model, you import the core module from the GitHub Actions Toolkit, which ply several utility mapping for working with inputs, outputs, and the execution surroundings.
• The script fulfill the measure defined in the workflow, such as lead bid (echo & # 8216; Hello, World! & # 8217;)and setting output variable(core.setOutput (& # 8216; myOutputVariable & # 8217;, & # 8216; Hello from local testing! & # 8217;)).

Step 3: Run the Test Script

To run the test script and simulate the workflow execution topically, fulfil the following command in our terminal or dictation prompt:

node test.js

• This will execute the test hand and provide output and feedback base on the steps defined in the script.
• By running the test script topically, you can formalize the behaviour of our GitHub Actions workflow, screen different input and outputs, and debug any issues that arise.
• This allow for faster iterations and troubleshooting without the need to push modification to the GitHub repository.

Method 2. Using a Third-Party Tool & # 8211; Act CLI

Method 3. Running GitHub Actions Locally with BrowserStack

• Running allows us to leverage to execute our workflows on various browsers and device.
• This method is particularly useful for testing web applications and ensuring cross-browser compatibility.

A more detailed explanation of how to run GitHub Actions topically with BrowserStack follows:

Step 1: Set Up a Local Development Environment

SUSA automates exploratory testing with persona-driven behavior, catching bugs that scripted automation misses.

Before go GitHub Actions locally with BrowserStack, ensure that you have a local development surroundings set up on our machine. This typically include an operating system, a codification editor or IDE, and the necessary tools and dependencies for our task.

Step 2: Configure GitHub Actions Workflow for BrowserStack

Modify our GitHub Actions workflow file to incorporate BrowserStack & # 8217; s browser-specific testing potentiality. BrowserStack provides pre-configured GitHub Actions activeness that permit us to determine the browsers and devices on which you desire to run our tests.

Example of how to configure our workflow to run tests habituate BrowserStack:

name: BrowserStack Local Testing on: [get-up-and-go] jobs: test: runs-on: ubuntu-latest steps: - gens: Set up Node.js uses: actions/setup-node @ v2 with: node-version: '14' - name: Checkout code uses: actions/checkout @ v2 - name: Install dependencies run: npm ci - name: Run test uses: browserstack/github-action @ v2 with: browsers: chrome, firefox build-name: GitHub Actions Local Testing timeout: 300

In this example, the workflow is trigger on every push event. It scat on the up-to-the-minute Ubuntu environs, pose up Node.js, checks out the code, installs dependencies, and so habituate thebrowserstack/github-actionaction to run trial on Chrome and Firefox browsers. You can customize the browsers, build names, timeout, and other parameter establish on our requirements.

Step 3: Obtain BrowserStack Credentials

To use BrowserStack with GitHub Actions, you need to receive our BrowserStack credentials. if you don & # 8217; t hold one already. Once you hold our credentials (BrowserStack username and access key), you & # 8217; ll need to store them securely as secrets in our GitHub repository. Follow GitHub & # 8217; s documentation on how to add and manage repository secrets.

Step 4: Run GitHub Actions Locally with BrowserStack

To run the GitHub Actions workflow locally with BrowserStack, follow these steps:

1.Set up our local growth environment and assure that our project dependencies and BrowserStack-specific configurations are in place.

2.Open our terminal or command prompt and navigate to our task & # 8217; s root directory.

Execute the following command:

npx github-action-local-runner run -e BROWSERSTACK_USERNAME= & lt; username & gt; -e BROWSERSTACK_ACCESS_KEY= & lt; access-key & gt;

3.Replace & lt;username& gt; and & lt;access-key& gt; with our actual BrowserStack credential. Thegithub-action-local-runnertool emulates the GitHub Actions environment locally and executes the workflow with the specified credentials.

4.The instrument will simulate the GitHub Actions runtime and communicate with BrowserStack & # 8217; s infrastructure to run tests on the specified browsers and devices. The tryout results and logs will be exhibit in the pole.
