Top 5 Best Practices For API Performance Testing

APIs play an essential role in implementing complex functionalities and helping your users access the data they need from your digital solution. Be it delivering accurate data or accessing complex data-dependent functionalities APIs can help you do it all!!

This makes APIs performance and accuracy very essential for businesses to ensure they provide their audience with effortless and reliable services. One of the best ways to achieve this is through API performance testing. It allows you to embed APIs into CI/CD pipeline and helps in identifying any performance, accuracy, and security issues regarding APIs beforehand. With this blog, we will take an in-depth look into how development teams can perform effortless API testing.

Why is API Performance Testing Essential?

Testing APIs are an essential feat that every development team must take while developing applications. As every API is unique and its behavior depends on multiple variables from the user’s end. Getting them checked consistently with proper strategy and test cases is essential to ensure your digital solution delivers what it’s supposed to. Here’s a list of reasons that makes testing API performance essential.

• API Endpoints are Unique: The API Performance directly depends on its endpoints and how they perform under different payloads. This makes testing API performance essential as every endpoint has its own unique behavior.
  

• Handles Finite Amount of Traffic: APIs tend to behave inconsistently as the payload increases from the threshold margin. Hence, to ensure APIs perform consistently testing them under different environments is essential.
  

• Ensure no Junk Data in the Database: Data accuracy is essential for APIs to provide end users with reliable and accurate data. Testing APIs' performance also ensures that they don’t deliver junk data and maintain an accurate database.
  

• Ensure Smooth API performance Across Multiple Devices: API performance testing also helps developers ensure that APIs provide accurate results and perform evenly across every device to make services easily accessible.

API Performance Testing Best Practices

Now, we can clearly conclude that API testing can easily help in maintaining the accuracy and effortless delivery of digital services. However, to ensure you neither cut the testing period too short nor stretch it beyond its need, adapting to best practices is a must. Here’s a detailed list of some of the best practices you must adapt to for smooth API performance testing:-

• Identification of Goals: Having clear goals for the performance testing process is essential. As it helps you in aligning your testing strategy according to the application-specific requirements for streamlined testing.
  

• Staging Environment Setup: Create an isolated environment separate from the live application for testing APIs. This allows developers to easily execute test cases and fix the bugs without affecting the main code. It ensures better accuracy and a reliable codebase for users.
  

• Testing Strategy: To ensure your API testing process becomes hassle-free and frictionless, create a testing strategy beforehand. This includes,

• Separating roles and responsibilities across the team

• Creating and validating test cases beforehand

• Setting testing timelines
  

• Automation: Automation helps in make the testing process faster and removes the uncertainty of human errors. To automate your testing of API performance you can integrate reliable automation tools.
  

• Testing maintenance strategy: API performance testing is never a one-time journey! As the user base grows and application rises in complexity ensuring APIs perform as intended is critical. For this, your team can create a testing maintenance strategy beforehand to ensure API performance remains consistent.
