Table-driven testing is a testing approach that allows multiple test cases to be structured in a tabular format. This method reduces code duplication by utilizing a single function to iterate over input and expected output pairs. It enhances maintainability since updates are localized to the test function rather than dispersed across multiple functions. The clear organization aids in demonstrating coverage of various inputs and edge cases, making it easier to add tests and understand the function being tested, thus becoming particularly popular for unit testing scenarios.
Table-driven testing is a testing paradigm where multiple test cases are defined in a structured format, typically as a collection of inputs and expected outputs.
This approach allows you to add new test cases by simply extending your test table rather than writing new test functions, reducing code duplication significantly.
The paradigm gets its name from how test cases are organized - like rows in a table where each row represents a complete test case.
Table-driven testing became popular for several compelling reasons, including improved maintainability and better visibility into test coverage.
