How to Test E-Commerce Websites and Applications Like Flipkart

The e-commerce business is increasing at a rapid pace, especially since Covid. So it is very important to test e-commerce websites and applications such as Amazon and Flipkart. Regressive testing of e-commerce applications is vital to make your app more robust and secure.

Effective manual and automation test strategies should be designed to test eCommerce applications. We need to make sure that all the pages of the application are tested regressively.

A test plan that covers all payment gateway test cases should also be created so that all the transactions are validated and secured. Load and Security testing should also be part of the test strategy to avoid compromises on loading time and mobile responsiveness. It would also protect the application from attacks by intruders.

Is your eCommerce app performing as you intended? Find out by employing testers from Testscenario. Get in touch with us!

Ecommerce application Architecture

An eCommerce application has 4 important elements – Main Pages, Product Pages, Product Description Pages, and Shopping Cart. Understand these in detail to test e-commerce websites and applications efficiently.

Main Pages include homepage, privacy page, about us page, careers, etc. Product Page includes different options for the product such as size, color, and other attributes. Sorting and filtering features are considered as part of product type pages along with add-to-cart and wishlist features.

Product description page includes title, description, images, add to cart feature and additional info, etc. The shopping cart page should include payment options and removing a product from the cart.

Overall, an eCommerce website or an application includes different user roles such as customers, partners, staff, and service agents. Backend infrastructures include rules, analytics, security, logging, and content management.

The first layer which is revealed to the users is the presentation layer that includes the UI for mobile, desktops. Responsiveness is kept in mind when designing this presentation layer.

Core Functionality includes Content, Marketing, Inventory Management, Orders, and Catalog. Back-office functionality includes fulfillment, inventory, payment, and Catalog staging.  The conceptional view is shown below.

Test strategy for eCommerce website

While testing an eCommerce application test strategy and test plan should be designed carefully. Let’s look at the test plan for an online shopping cart which includes different types of testing needed for an eCommerce website

  1. Browser Compatibility Testing

Ensuring that the application works seamlessly across major platforms (Linux, Windows, and Mac) and browsers (Chrome, Firefox, Safari, etc.) is crucial for providing a universally positive user experience. Browser compatibility testing helps in identifying and rectifying UI inconsistencies and functional issues across different environments.

  1. Load and Performance Testing

ECommerce sites experience variable traffic, with significant spikes during sales or promotional events (like Black Friday, Cyber Monday, etc.). Load and performance testing are critical to ensure that the website can handle high volumes of traffic and transactions without degradation in performance.

Testing for maximum load, response times, and the application’s ability to handle concurrent requests is necessary to ensure scalability and reliability under peak load conditions.Response time and loading time of the application should be tested in advance. Load balancers should be applied during extensive load testing.

  1. Functional Testing

Testing the functionalities of an eCommerce site is fundamental to ensure that all features work as intended. This includes testing the shopping cart, checkout process, payment gateway integration, product search and filter functions, and user account management features. Functional testing also encompasses UI testing to ensure the application is not only responsive but also intuitive and user-friendly across different devices and screen sizes.

  1. Security Testing

Security is paramount in eCommerce applications due to the handling of sensitive customer data and financial transactions. Security testing should cover various aspects, including data encryption, secure payment processing, protection against common web vulnerabilities (such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF)), and compliance with data protection regulations (like GDPR in Europe, CCPA in California, etc.).

Ensuring the security of customer data and transactions is crucial for maintaining trust and complying with legal requirements. There have been instances where data breaches happened in the past which cost businesses a lot of bucks. Hence, security should be the main testing for eCommerce applications.

How to test e-commerce websites manually

1. Develop a Comprehensive Test Plan: Start by defining the scope of testing, including all the pages and functionalities of the e-commerce website. This plan should detail the testing strategies for UI, functionality, compatibility, performance, security, and any other relevant tests.

2. Execute Test Cases for UI and Functional Testing: Manually walk through the website to test the user interface and the functionality of all features. This includes testing navigation, search functionality, product listing and details, shopping cart, checkout process, payment gateway integration, user registration, and login/logout functionalities.

3. Track Test Cases and Bug Reporting: Use a test management tool to track the progress of test cases and document any bugs or issues encountered during testing. Early detection and reporting of bugs within the Software Development Life Cycle (SDLC) can significantly reduce the cost and effort required for bug fixes.

4. Perform Exploratory Testing: Beyond structured test cases, engage in exploratory testing to uncover issues that may not have been anticipated in the test plan. This involves creatively testing the application to identify potential weaknesses or unexpected behavior.

5. Test Across Different Devices and Browsers: Manually test the website on various devices (desktops, tablets, smartphones) and browsers (Chrome, Firefox, Safari, etc.) to ensure compatibility and responsive design.

How to Testing E-commerce Websites Using Selenium and Other Tools

1. Functional Testing with Selenium/Appium: Selenium, with Appium for mobile applications, allows for the automation of web browser actions to test the functionality of e-commerce websites. Testers can write scripts in languages supported by Selenium (like Java, C#, Python) to automate test cases for different functionalities.

2. Performance Testing with JMeter: Apache JMeter can be used for performance testing to simulate a large number of users accessing the website simultaneously. This helps in identifying bottlenecks and ensuring that the website can handle peak traffic loads.

3. Security Testing with ZAP OWASP: The Zed Attack Proxy (ZAP) by OWASP is a tool for finding vulnerabilities in web applications. It can be used to perform automated scans and identify security threats like SQL injection, cross-site scripting, and other vulnerabilities.

4. Automating Unit Testing: Developers can automate unit tests using the programming language in which the application is developed. Frameworks like JUnit (for Java), PyTest (for Python), and NUnit (for .NET) can be used for writing and executing unit tests.

By combining manual testing strategies with automated tools like Selenium, JMeter, and ZAP OWASP, teams can ensure comprehensive coverage of all critical aspects of e-commerce website testing. This dual approach helps in maximizing the efficiency of the testing process, ensuring a high-quality user experience, and maintaining the security and performance of the e-commerce platform.
