As per the latest reports by Statista, Instagram currently has 2 billion active users, holding the fourth spot for the most used social media application. The footfall is only going to increase every year. But how does the company manage such a tremendous amount of visitors? Surely, neither the company nor the users want to experience even a second of downtime. Managing the existing load and functionality while preparing for future scalable possibilities comes with proper software testing and development. In the case of Instagram, you only need this guide to cover all the test cases of Instagram that ensure present and subsequent testing scenarios.

But first….

Why Test Instagram?

To make sure that the app works how it is expected to work!

Honestly, the answer lies in multiple spots. Instagram requires thorough testing for personal and professional use as both individuals and organizations avail app features. UI/UX, functional, visual, and cross-platform testing are just some of the validating criteria. 

Furthermore, it is but one social media site among many, all of which can be integrated into each other. Testing needs to run for integration and security as well.

Types of Tests to Run for Instagram

As a rule of thumb, before you begin testing, have an idea of how many testing types you would need to run for the project. The below list will give you an idea about validating Instagram features. Formulate your test case techniques based on this if you want.

Functional Testing

  • Feature Testing: Verify each feature on Instagram, including posting, commenting, liking, direct messaging, etc.
  • Integration Testing: Ensure seamless integration of Instagram with third-party applications, APIs, or services.
  • Compatibility Testing: Validate the app’s compatibility across different devices, operating systems, and browsers to ensure consistent performance.
  • Security Testing: Assess the security measures of Instagram, including data protection, authentication, and authorization mechanisms.

Non-functional Testing

  • Performance Testing: Measure Instagram’s performance metrics, such as load time, response time, and scalability, under various conditions.
  • Usability Testing: Evaluate the user-friendliness of the app, including navigation, layout, and accessibility.
  • Reliability Testing: Determine the reliability and stability of the app by testing for error handling, crash recovery, and uptime.
  • Scalability Testing: Assess Instagram’s ability to handle increasing loads and user traffic without compromising performance or functionality.
