Many traditional software testing methods follow strict rules, assuming that the same approach works for every project. However, every software project is different, with unique challenges, requirements, and constraints. Context-Driven Testing (CDT) is a flexible testing approach that adapts strategies based on the specific needs of a project instead of following fixed best practices, CDT encourages testers to think critically and adjust their methods based on project goals, team skills, budget, timelines, and technical limitations. This approach was introduced by Cem Kaner, James Bach, and Bret Pettichord, who emphasized that there are no universal testing rules—only practices that work well in a given context. CDT is particularly useful in agile projects, startups, and rapidly changing environments where requirements often shift. It allows testers to adapt in real time, ensuring testing remains relevant and effective. Unlike traditional methods that focus only on whether the software meets requirements, CDT ensures the product actually solves real problems for users. By promoting flexibility, collaboration, and problem-solving, Context-Driven Testing helps teams create high-quality software that meets both business and user expectations. It is a practical, efficient, and intelligent approach to testing in today’s fast-paced software development world.
The Evolution of Context-Driven Testing in Software Development
Software testing has evolved from rigid, standardized processes to more flexible and adaptive approaches. Context-driven testing (CDT) emerged as a response to traditional frameworks that struggled to handle the unique needs of different projects.
Early Testing: A Fixed Approach
Initially, software testing followed strictly defined processes with heavy documentation and structured test cases. Waterfall models required extensive upfront planning, making it difficult to adapt to changes. These methods often led to:
Lack of flexibility in dynamic projects
Inefficient use of resources, focusing on documentation over actual testing
Misalignment with business needs, causing ineffective testing outcomes
With the rise of Agile development, testing became more iterative and collaborative, allowing testers to:
Think critically instead of following rigid scripts
Adapt quickly to changes in project requirements
Prioritize business value over just functional correctness
However, exploratory testing lacked a structured decision-making framework, leading to the need for Context-Driven Testing.
The Birth of Context-Driven Testing
CDT was introduced by Cem Kaner, James Bach, and Bret Pettichord as a flexible, situational approach to testing. It focuses on:
Tailoring testing methods based on project context
Encouraging collaboration between testers, developers, and stakeholders
Adapting continuously as projects evolve
This made CDT highly effective for Agile, DevOps, and fast-paced development environments.
CDT in Modern Software Development
Today, CDT remains crucial in handling complex software systems such as AI-driven applications and IoT devices. It continues to evolve by:

By using Playwright, testers can efficiently validate API endpoints, perform authentication checks, and seamlessly integrate API tests with UI tests to ensure consistent functionality across the entire application. API testing with Playwright allows for the testing of various HTTP methods, including GET, POST, PUT, and DELETE requests, enabling comprehensive validation of data flow and business logic. Additionally, Playwright supports handling complex authentication scenarios, such as token-based and OAuth authentication. This guide will explain why Playwright is an excellent choice for API testing, how to set it up and provide detailed examples of requests, authentication handling, and best practices for effective and efficient API testing.
Basics of API Testing
API testing checks if different software systems can communicate and exchange data correctly. It ensures functionality, security, and performance while being faster and easier to automate than UI testing. Unlike UI testing, which focuses on visual elements, API testing verifies the backend logic using requests like GET and POST. It also differs from unit testing, which tests individual functions, and integration testing, which checks how system parts work together.
Why Choose Playwright for API Testing?
API testing is a crucial aspect of software testing, ensuring that backend services function correctly before integrating them with the UI. Several tools are available for API testing, each offering unique features suited to different testing needs:
Postman – A widely used API testing tool with a graphical interface for sending requests and validating responses.
RestAssured – A Java-based API testing framework commonly used for automated API validation.
SoapUI – A dedicated tool for testing SOAP and REST APIs, offering advanced features for functional and security testing.
SuperTest – A JavaScript library designed for testing HTTP APIs, particularly useful in Node.js applications.
Cypress – Primarily a UI testing framework that also includes basic API testing capabilities.
Then why should we use Playwright for API testing? It allows users to make API requests, validate responses, and integrate API checks within automated test scripts. It provides features like APIRequestContext for direct API interactions, built-in authentication handling, and cross-browser support, making it a versatile option for teams looking to perform both API and UI testing within the same environment. Like other tools, Playwright offers a structured approach to API testing, enabling efficient validation of backend services. Now let’s take a deeper look at all the key features.
Key Features of Playwright That Enhance API Testing
1. Built-in APIRequestContext for Simplified API Testing
Playwright provides APIRequestContext, allowing testers to make API calls directly within test scripts without needing external libraries like Axios or SuperTest.
Why Playwright? Unlike Postman (which is UI-based) and RestAssured (which requires Java), Playwright allows API requests directly within the test automation framework with minimal setup.
2. Seamless Integration of API & UI Testing
Unlike Postman, RestAssured, and SoapUI, which focus only on API testing, Playwright enables UI and API tests to run in the same framework. This is useful for:
Setting up test data via API before UI tests.
Validating API responses against UI elements.
Testing UI interactions that trigger API calls.
Example: API and UI Test Together
test('Create user via API and validate on UI', async ({ page, request }) => {
const response = await request.post('https://jsonplaceholder.typicode.com/users', {
data: { name: 'John Doe', email: '[email protected]' }
});
expect(response.status()).toBe(201);
const user = await response.json();
await page.goto('https://example.com/users');
const userExists = await page.locator(`text=${user.name}`).isVisible();
expect(userExists).toBeTruthy();
});

4. Cross-Browser & Cross-Platform API Testing
Unlike most API testing tools that only test API responses, Playwright supports cross-browser validation, ensuring that API responses work correctly with different browsers.
Example: API Test Across Browsers
import { test, expect, request } from '@playwright/test';
test('Validate API response in different browsers', async ({ browser }) => {
const context = await browser.newContext();
const request = context.request;
const response = await request.get('https://jsonplaceholder.typicode.com/posts/1');
expect(response.status()).toBe(200);
});
Why Playwright?
Postman, RestAssured, and SoapUI cannot test how APIs behave across different browsers.
Playwright ensures API + UI compatibility across Chromium, Firefox, and WebKit (Safari).
5. CI/CD Integration for Automated API Testing
Playwright works seamlessly with CI/CD pipelines, allowing automated API testing in:
Jenkins
GitHub Actions
GitLab CI/CD
Example: Running Playwright API Tests in GitHub Actions

runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout@v2
- name: Install dependencies
run: npm install
- name: Run API Tests
run: npx playwright test api-tests
Why Playwright? Unlike Postman, which requires Newman for automation, Playwright runs API tests directly in CI/CD pipelines without additional setup.

Millions of people with disabilities rely on assistive technologies to navigate websites, applications, and digital content. Among these technologies, screen readers play a vital role in making digital platforms usable for individuals with visual impairments, cognitive disabilities, and other accessibility needs. Despite advancements in web development and design, many digital platforms still fail to accommodate users who depend on screen readers. Without proper accessibility testing, visually impaired users encounter significant barriers that prevent them from accessing information, completing transactions, or even performing basic online interactions. In this blog, we will explore the critical role of screen reader accessibility testing, the consequences of inadequate screen reader support, and the legal mandates that ensure digital inclusivity for all.
What Happens Without a Screen Reader?
For individuals who are blind or visually impaired, accessing digital content without a screen reader can be nearly impossible. Screen readers convert on-screen text, buttons, images, and other elements into speech or braille output, allowing users to navigate and interact with websites and applications. Without this assistive technology:
Navigation Becomes Impossible: Users cannot “see” menus, buttons, or links, making it difficult to move through a website.
Critical Information is Lost: Important content, such as descriptions of images, form labels, and error messages, is inaccessible.
Online Interactions Become Challenging: Tasks like shopping, filling out forms, and accessing services require proper accessibility support.
Without screen reader support, digital exclusion becomes a reality, limiting independence and access to essential services.
How Testers Evaluate Websites Using Screen Readers
Testers play a crucial role in ensuring websites are accessible to individuals with disabilities by using the same screen reader tools that visually impaired users rely on. By testing digital platforms from an accessibility perspective, they identify barriers and ensure compliance with accessibility standards like WCAG, ADA, and Section 508.
Here’s how testers evaluate a website using screen readers:
Text-to-Speech Verification: Testers use screen readers like NVDA, JAWS, and VoiceOver to check if all on-screen text is correctly converted into speech and read in a logical order.
Keyboard Navigation Testing: Since many users rely on keyboard shortcuts instead of a mouse, testers verify that all interactive elements (menus, buttons, links) can be accessed and navigated using keyboard commands.
Form Accessibility Checks: Testers confirm that screen readers correctly read out form labels, input fields, and error messages, allowing users to complete online transactions without confusion.
Image & Alt Text Validation: Using screen readers, testers ensure that images have proper alt text and that decorative images do not interfere with navigation.
By incorporating screen reader testing into their accessibility audits, testers help developers create an inclusive experience where visually impaired users can navigate, interact, and access content effortlessly.
A sample video explains how to perform testing using screen readers.
(In the shared video, we identified a bug related to the list items on the page. There is a single list item enclosed within ‘ul’ and ‘li’ tags, which is unnecessary for the content. This should be changed to a ‘p’ or ‘span’ tag to better suit the structure and purpose of the content.)
