Get a Personalized ShortlistRegression Testing vs. Unit Testing: Key Differences
Feature | Regression Testing | Unit Testing |
---|---|---|
Definition | Verifies that existing functionalities haven't broken due to code changes or new features. | Tests individual units of code (functions, modules) in isolation to ensure they work as expected. |
Focus | System behavior after changes, preventing regressions. | Individual code units and their correctness. |
Timing | Performed after any significant code change (bug fix, new feature) before deployment. | Usually conducted early in the development cycle, after code is written. |
Test cases | Designed to cover existing functionalities that changes might impact. | Focused on specific code units and their expected outputs for various inputs. |
Tools used | Automated testing frameworks and regression testing tools. | Automated testing frameworks, mocking frameworks. |
Outcome | Identifies regressions caused by changes and ensures existing functionality remains intact. | Determines if individual code units function as expected, catching bugs early in development. |
Example | Testing if a new login feature affects existing user functionalities like profile management. | Testing if a function calculating shipping costs produces the correct output for different addresses and weights. |
Frequency | Conducted regularly, especially after code changes, updates, or system enhancements, to detect regressions. | Typically performed whenever a unit of code is written or modified to ensure the correctness of the code. |
Dependencies | Dependent on the accuracy and completeness of the regression test suite to provide reliable results. | Dependent on the correctness and effectiveness of the unit test cases to ensure proper functioning of the code. |
