Building test cases for e-commerce applications

Testing processes for e-commerce.

Test cases fall under a vital part of QA best practices because they directly or indirectly influence the whole process of quality assurance. When a product is under development each and every stage has to be quality checked before it is moved to production. For Ecommerce websites, every page in the website matters for the website quality and business

Home page

Home page is the starting point of any application. When a user first enters the site they actually see home page which acts as a deal breaker or maker to the site. Home page should be crisp and neat and not too much loaded with contents.

  • Major aspect to check in home page is loading time.
  • The auto-scrolling feature is present or not.
  • How much time is being taken to change the slides?
  • How long are the tabs taking to open and if it is working properly?
  • Are the interactive features of the website functioning properly?

Search feature

The search feature is an important aspect of the Ecommerce project because it influences the user experience to a huge extent. The search option present on the site should possess filtering capabilities in order to find the clients exactly what they are looking for.

  • If the drop-down list is coming with proper names of items.
  • If the name is wrong or there is a typing error, will the search list show the corrected recommendations?
  • How much time searching feature is taking to display the contents.
  • Will it rectify the typing mistakes and show the corrected names.
  • On typing the wrong name, will the search list show the corrected name or not.

The search feature is directly associated with the user experience of the site. Customers are heading towards an eCommerce site mainly to make a purchase from their collection. So if the search option itself is giving them a hard time, then the targeted audience will eventually lose interest in making a purchase.

Functional testing is a type of software testing that validates the software system against the functional requirements/specifications

  • Mainline functions:  Testing the main functions of an application
  • Basic Usability: It involves basic usability testing of the system. It checks whether a user can freely navigate through the screens without any difficulties.

Types of Performance testing – Load testing, Stress testing, Endurance testing, Spike testing, Volume testing, Scalability testing.

Database Testing is checking the schema, tables, triggers, etc. of the database under test. It may involve creating complex queries to load/stress test the database and check its responsiveness. It Checks data integrity and consistency.

A/B testing (also known as split testing or bucket testing) is a method of comparing two versions of a webpage or app against each other to determine which one performs better. AB testing is essentially an experiment where two or more variants of a page are shown to users at random, and statistical analysis is used to determine which variation performs better for a given conversion goal.
