Table Driven Test

A loop over small input and expected-output tables can test a method repeatedly.

TableDrivenTest.java

public class TableDrivenTest {
    static int clampLow(int value) {
        if (value < 0) {
            return 0;

        int offset = ;
        int[] inputs = {-2, 0, 5};
        int[] expected = {0, 0, 5};
        int failures = 0;

        for (int i = 0; i < inputs.length; i++) {
            int actual = clampLow(inputs[i] + offset);
            if (actual != expected[i]) {
                failures++;
            }
        }

        System.out.println("failures=" + failures);

test table Each array index represents one test case.

failure count Counting mismatches gives a compact summary of the test run.
