Postman with Newman – Run API Tests from the Command Line Like a Pro

Postman with Newman – A Complete Guide for API Test Automation

Postman is a popular tool for testing RESTful APIs. While it's great for manual testing, running tests as part of automation or CI/CD pipelines requires a command-line interface. That’s where Newman comes in!

🚀 What is Newman?

Newman is Postman’s command-line tool that lets you run Postman collections directly from your terminal. It allows automated API testing and is perfect for continuous integration workflows.

🛠️ How to Set Up Postman with Newman

Step 1: Install Node.js

Download and install Node.js from https://nodejs.org/.

Step 2: Install Newman

Open your terminal and run:

npm install -g newman

Step 3: Export Postman Collection

• Open Postman app
• Select your collection → click "..." → Export
• Choose "Collection v2.1 (recommended)" format

Step 4: Run Collection Using Newman

newman run your_collection.json

🧪 Run with Environment File

newman run your_collection.json -e your_environment.json

📊 Generate HTML Report

npm install -g newman-reporter-html
newman run your_collection.json -r html

🔁 Run with Data File (CSV or JSON)

newman run your_collection.json -d data.csv

⚙️ CI/CD Integration Ideas

• Jenkins: Add as a shell step
• GitHub Actions: Add in your YAML workflow
• GitLab CI: Include in your .gitlab-ci.yml

✅ Summary

Newman helps you automate Postman collections via CLI, making your API tests easily repeatable, CI/CD-friendly, and reportable. This approach saves time, improves accuracy, and helps detect issues earlier in the development cycle.

Integrating Selenium with Java and OpenAI API – Intelligent Automation for QA Engineers

🧠 Integrate Selenium with Java and OpenAI API – Full Guide

This guide shows how to use Selenium for web automation with OpenAI’s Java SDK. Learn how to retrieve your API key, manage it securely, and write a test script that interacts with OpenAI and a web page.

🔑 How to Get Your OpenAI API Key

1. Go to https://platform.openai.com/signup and sign up or log in.
2. Once logged in, click on your profile (top-right) > API keys.
3. Click Create new secret key and copy the key securely.

⚠️ Do not share your API key publicly. Store it safely using a .env file as explained below.

📦 Maven Project Setup

In your Java Maven project’s pom.xml, add these dependencies:

<dependencies>
  <!-- Selenium WebDriver -->
  <dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>4.8.0</version>
  </dependency>

  <!-- OpenAI Java Client (Theo Kanning's library) -->
  <dependency>
    <groupId>com.theokanning.openai-gpt3-java</groupId>
    <artifactId>client</artifactId>
    <version>0.18.2</version>
  </dependency>

  <!-- dotenv-java to manage environment variables -->
  <dependency>
    <groupId>io.github.cdimascio</groupId>
    <artifactId>dotenv-java</artifactId>
    <version>5.2.2</version>
  </dependency>
</dependencies>

🔐 Step: Setup .env File

Create a file named .env in your project’s root folder with this content:

OPENAI_API_KEY=your_openai_api_key_here

Also add .env to your .gitignore file to keep your API key private.

💻 Real-World Java Example with OpenAI + Selenium

This example uses Selenium to open a flight search website and OpenAI to generate a user tip for filling out the form.

import io.github.cdimascio.dotenv.Dotenv;
import com.theokanning.openai.service.OpenAiService;
import com.theokanning.openai.completion.CompletionRequest;
import com.theokanning.openai.completion.CompletionChoice;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class FlightAutomationExample {
    public static void main(String[] args) {
        // Load environment variables
        Dotenv dotenv = Dotenv.load();
        String apiKey = dotenv.get("OPENAI_API_KEY");

        // Initialize OpenAI
        OpenAiService service = new OpenAiService(apiKey);

        // Use OpenAI to generate a flight booking tip
        CompletionRequest request = CompletionRequest.builder()
            .prompt("Give one important tip for booking flights online.")
            .model("text-davinci-003")
            .maxTokens(100)
            .build();

        CompletionChoice choice = service.createCompletion(request).getChoices().get(0);
        System.out.println("OpenAI Tip: " + choice.getText());

        // Launch browser with Selenium
        WebDriver driver = new ChromeDriver();
        driver.get("https://www.example.com/flights");

        // You can automate actions here, e.g., filling a form, clicking search, etc.

        driver.quit();
    }
}

✅ Summary

• 💡 Use OpenAI to generate smart content or logic in your automation tests.
• 🧪 Use Selenium for browser testing or automation steps.
• 🔐 Secure API keys using dotenv-java in your Maven project.

By combining these technologies, you can bring intelligence to your automation framework, such as generating test data, writing user prompts, or analyzing UI interactions.
