A Day in the Life of a QA Working on a Medical App

ЁЯй║ A Day in the Life of a QA Working on a Medical App

Working in QA for a medical application isn’t just about writing test cases — it’s about ensuring patient safety, data privacy, and compliance with healthcare regulations. Here's what a typical day looks like for me:

ЁЯХШ 9:00 AM – Morning Standup

We start the day with a daily stand-up call. The product team, developers, and QAs share updates. For me, this is the time to raise concerns about yesterday’s test results or any blockers in automation runs.

ЁЯУД 10:00 AM – Reviewing Requirements

Before diving into testing, I read through user stories and FSDs (Functional Spec Documents). In the medical domain, I verify that all HIPAA compliance notes and audit trail requirements are clear.

ЁЯзк 11:00 AM – Manual Testing Critical Flows

I start by manually testing critical flows like patient registration, appointment booking, EMR (Electronic Medical Records) viewing, and prescription generation. I focus on edge cases, validation, and field-level security.

ЁЯТ╗ 1:00 PM – Automation Script Review

Post-lunch, I review the automated Selenium + Java test cases that ran on Jenkins overnight. If any failed, I analyze logs, screenshots, and check whether the failure is due to flaky scripts or actual application issues.

ЁЯУ▓ 2:30 PM – API Testing with Postman

I test appointment APIs, authentication tokens, and data sync endpoints using Postman. For medical apps, secure transmission of patient data (often in JSON or HL7 format) is critical.

ЁЯЫб️ 4:00 PM – Compliance & Security Checklist

I perform checks for access control, role-based permissions (Doctor, Nurse, Admin, Patient), and ensure error messages don’t leak sensitive data. I also check that sessions time out securely and that data is encrypted at rest.

ЁЯУЛ 5:30 PM – Bug Reporting & Test Case Updates

By end of day, I log all bugs found in Jira, update the test case execution sheet, and document regression impacts if needed. I also prepare for the next day’s test plan and share a status update with the team.

ЁЯФЪ Final Thoughts

Being a QA in a healthcare app requires technical expertise and a sense of responsibility. One bug can impact real people’s health — so attention to detail and rigorous validation is not optional, it’s mandatory.

If you're working in or planning to join healthcare QA, let me know your experiences or doubts in the comments!

Case Study: Testing a Food Delivery App (Real Project Tasks)

ЁЯУж Case Study: Testing a Food Delivery App (Real Project Tasks)

In this case study, I’ll walk you through how I tested a real-world food delivery application, covering the different types of testing I performed and the actual modules I worked on.

ЁЯУ▒ Application Overview

  • Platform: Web and Mobile App (iOS & Android)
  • Users: Super Admin, Restaurant Admin, Customer, Delivery Boy
  • Tech Stack: React, Node.js, MongoDB, Firebase

ЁЯзк Testing Types Performed

  • Functional Testing – Verified core features like order placement, payment, and delivery flow.
  • UI Testing – Checked responsiveness, alignment, and element visibility across devices.
  • Regression Testing – After each deployment or feature enhancement.
  • Cross-Browser Testing – Chrome, Firefox, Safari compatibility for web interface.
  • API Testing – Used Postman to validate RESTful endpoints for user login, orders, and menu updates.

ЁЯзС‍ЁЯТ╗ Modules Tested

  • ЁЯФР User Registration & Login (OTP & Email-based)
  • ЁЯНФ Restaurant Menu Management (CRUD operations)
  • ЁЯЫТ Cart & Checkout Flow (Add, remove items, promo codes)
  • ЁЯТ│ Payment Integration (Razorpay/Stripe sandbox testing)
  • ЁЯЪ┤ Order Assignment to Delivery Boys
  • ЁЯУН Real-Time Order Tracking (Google Maps)
  • ЁЯУК Admin Dashboard Analytics & Reports

ЁЯУЭ Sample Test Case Table

Test Case Expected Result Status
The user places an order with a valid payment The order should be accepted and visible in the order history Pass
The delivery boy accepts the order Status changes to "Out for delivery" Pass
Invalid promo code applied Display appropriate error message Pass

ЁЯРЮ Bugs Found

  • Promo code applied multiple times in the cart
  • The order tracking map is not loading on iOS
  • Menu item image upload fails on slow network
  • Delivery boy app crashes on auto logout

ЁЯФЪ Conclusion

This project helped me gain practical experience in end-to-end QA for a multi-user food delivery ecosystem. It involved API testing, real-time validations, UI cross-checks, and regression cycles. A strong reminder that good testing means thinking like both the customer and the developer.

Postman vs Swagger – Which Is Better for QA?

Postman vs Swagger – Which Is Better for QA?

In the world of API testing, Postman and Swagger (now called Swagger UI / OpenAPI) are two of the most commonly used tools by QA professionals. Each tool offers different benefits depending on your project needs, technical skills, and integration with development workflows.

What Is Postman?

  • A powerful GUI-based tool for testing REST APIs.
  • Supports scripting (Pre-request, Tests), environment variables, and automation.
  • Easy to use for manual testing and automation with the Postman Collection Runner and Newman CLI.

What Is Swagger?

  • A framework for API design, documentation, and testing using the OpenAPI Specification.
  • Swagger UI provides interactive documentation.
  • Swagger Editor allows you to define and mock APIs before development.

Postman vs Swagger: Feature Comparison

Feature Postman Swagger
Best For QA Testing and Automation API Design and Documentation
Ease of Use Very User Friendly Requires YAML/JSON knowledge
Automation Supports via Collection Runner, Newman Limited built-in automation
API Mocking Supported via Postman Mock Servers Supported
Integration Jira, Jenkins, GitHub, etc. Mostly with Dev Tools

When to Use Postman?

  • You're a QA tester needing quick, efficient REST API testing.
  • You need to run test collections and automate regression API testing.
  • You work in Agile/Scrum where endpoints change frequently.

When to Use Swagger?

  • You are part of the development team responsible for API documentation.
  • You want to design APIs before implementation.
  • You want developers and testers to visualize endpoints in one place.

Final Verdict

Use both! Postman and Swagger complement each other. Swagger is great for API documentation and early design, while Postman is better for actual testing, validation, and automation.

ЁЯТб Pro Tip: Many teams use Swagger to define APIs and Postman to test them.

Top 5 Selenium Interview Questions – With Code Answers

ЁЯЪА Top 5 Selenium Interview Questions – With Code Answers

If you're preparing for a QA Automation role using Selenium, here are the most frequently asked Selenium interview questions along with practical code answers using Java and TestNG.


1️⃣ What is Selenium WebDriver? How do you launch a browser using it?

Answer: Selenium WebDriver is a tool for automating web application testing. It provides a programming interface to interact with web elements.

WebDriver driver = new ChromeDriver();
driver.get("https://www.google.com");

2️⃣ How to handle dropdowns in Selenium?

Answer: You can use the Select class to handle dropdowns.

WebElement dropdown = driver.findElement(By.id("country"));
Select select = new Select(dropdown);
select.selectByVisibleText("India");

3️⃣ How to handle Alerts in Selenium?

Answer: Selenium provides the Alert interface to handle JavaScript alerts.

Alert alert = driver.switchTo().alert();
System.out.println(alert.getText());
alert.accept();

4️⃣ What is the difference between driver.close() and driver.quit()?

  • close(): Closes the current active window.
  • quit(): Closes all the windows opened by WebDriver and ends the session.

5️⃣ How to perform mouse hover action in Selenium?

Answer: Use the Actions class for mouse interactions.

Actions actions = new Actions(driver);
WebElement element = driver.findElement(By.id("menu"));
actions.moveToElement(element).perform();

ЁЯТб Bonus Tip

Always combine Selenium with TestNG or JUnit for structured automation testing and reporting. Employers prefer candidates who can write modular, reusable test scripts.
