Backend Testing
Backend testing can be divided into two categories as well as the frontend - manual & automated. There are several types of automated testing in a different levels of the development & deployment process with the goal to achieve the best quality of the final product.
Manual testing
Manual backend testing for APIs involves validating the functionality, security, and performance of server-side components by simulating real-world scenarios without automation. Testers manually send requests to APIs, check the responses, and ensure that the data flow between the front-end and back-end meets the expected requirements. This type of testing is crucial for identifying issues like incorrect data processing, security vulnerabilities, or performance bottlenecks that could impact the overall system. In this case the most used tool is Postman.
Automation testing
Automation testing for backend APIs using a custom testing framework involves writing scripts to validate API functionality, security, and data integrity automatically, ensuring consistent results across multiple test cases. For performance testing, Azure Load Tests in cooperation with JMeter simulate high traffic volumes to measure the scalability and reliability of backend services under various load conditions, helping identify potential bottlenecks and optimize performance.
Frontend Testing
Frontend testing ensures the functionality, usability, and visual consistency of a software’s user interface, validating that it behaves as expected across different devices, browsers, and user interactions.
Bugs & Issues
Bugs and issues in software can lead to crashes, data loss, or poor user experiences, making it essential to detect and fix them during testing. Addressing these problems early ensures a reliable, secure product, reduces costs, and protects a company’s reputation.
