What is API Testing?
- API testing is a type of software testing that focuses specifically on testing the Application Programming Interfaces (APIs) of a software application.
- API testing ensures that these APIs function correctly, provide the expected outcomes, and adhere to their specified behaviour.
- Testing APIs helps identify issues related to functionality, integration, data flow, security, and performance.
Key aspects of API testing include:
- Functional Testing
- Integration Testing
- Data Validity and Flow
- Error Handling
- Security Testing
- Performance Testing
- Regression Testing
- Usability Testing
What is meaning of API?
- API stands for “Application Programming Interface.” It is a set of protocols, routines, tools, and definitions that allow different software applications to communicate with each other.
- APIs define the methods and data structures that developers can use to interact with a particular software component, service, or system without having to understand the internal implementation details.
What is meaning of Testing?
- Testing, in the context of software development and other fields, refers to the process of evaluating a product, system, or component to identify its quality, correctness, and performance.
- The primary goal of testing is to uncover defects, errors, or issues in the product being tested, which can range from software applications to physical devices.
