Overview Of API Testing
To start, The rise of cloud applications and interconnected platforms increases the demand of API testing.It has become vital with the large usage of API services.API testing has become essential for software developers.Let's examine AWS, including why it's crucial and how to use it.
API Testing is the important software testing type that is used to validate Application Programming Interfaces (APIs). It focuses on the business logic layer of the software.The purpose of API Testing is to check the programming interfaces with its,
API Testing Approach is a predefined strategy to conduct the API testing. It helps to better understand the functionalities, testing techniques, input parameters and the execution of test cases.
Why is API testing important?
The most important factor is the high adoption of API testing by multiple companies. API Testing Market size is expected to reach USD 5,328 Million by 2030 from USD 937.51 Million in 2021.
API testing can analyze
- Web services
- Web user interfaces
To perform API testing automation, multiple tool sets and libraries are available.It is used to save the manual effort to test the whole set of APIs.With API testing, Detect the bugs and defects at very early stages. It saves the cost.It takes less time with the same set of scenarios and parameters changes.
When the same application is expected to be available in different platforms like mobile, desktop, the same set of API is used. It provides performance check.API is used to fetch out data for checking the performance of the overall application. API tests are fast and used to validate the business logic and other aspects of the application.
API Testing Process
- Testing Scope
- Test Cases
- Test results
An API testing process begins with a clearly defined scope of the program by understanding the functionality of the API.
Write test cases by applying testing techniques for the API.API test cases define the conditions or variables to determine the performance of a specific system.
Plan Input Parameters with proper definition for the API testing.API Testing require the initial environment to invoke API with a required set of parameters.
The tester performs the test and analyzes the responses which includes: response time, data quality, authorization, HTTP status codes, error codes.Response time should be within a defined limit that teams deem acceptable, and the API should be secured against potential attacks.Now compare the actual results with the expected results.
Types of API OutputAn output of API could be
- Data(Any type)
- Another API function call
Testers should note the failures or unexpected inputs. Analyze the results of nonfunctional tests,performance and security.
Types of API tests
API tests cover the following testing methods to check application programming interface.
- Validation testing
- Functional testing
- Usability Testing
- Load testing
- Discovery testing
- Reliability testing
- Security testing
- Penetration testing
