What is Testing?
It is the process of verifying the quality, functionality, and performance of a software product.
Definition
Testing, or test, is a procedure conducted to verify and validate the functionality, performance, security, and usability of a software product. This process is crucial for identifying and correcting errors, inconsistencies, or any other issues before the product is released to the market or delivered to the client.
Evolution
Testing activities have evolved with new techniques and approaches as applications become more complex.
Acceptance Testing
UAT (User Acceptance Testing) verifies if the entire system works as intended.
Code Review
Confirms that new and modified software adheres to coding standards and best practices.
Integration Testing
Integration tests ensure that software components or functions work together.
Unit Testing
Unit tests check that each unit of the software operates as expected.
Functional Testing
Functional tests validate the system's functionalities by simulating user interaction scenarios based on specified requirements.
Performance Testing
Performance tests evaluate the software's performance under different workloads.
Regression Testing
Regression tests check if new features break or degrade functionality.
