You might have also noticed in TestSimpleVariadicToSlice that we duplicated a lot of logic, while the only varying factor was the input and expected values. One style of testing, known as Table-driven development, defines a table of all the required data to run a test, iterates over the "rows" of the table and runs tests against them.

Let's look at the tests we will be testing against no arguments and variadic arguments:

// addInt_test.go package main import ( "testing" ) func TestAddInt(t *testing.T) { testCases := []struct { Name string Values []int Expected int }{ {"addInt() -> 0", []int{}, 0}, {"addInt([]int{10, 20, 100}) -> 130", []int{10, 20, 100}, 130}, } for _, tc := range testCases { t.Run(tc.Name, func(t *testing.T) ...
