教程
设置单元测试：
import (
"testing"
)
func TestAdd(t *testing.T) {
// ...
}编写断言：
if output != expected {
t.Errorf("Expected %v, got %v", expected, output)
}覆盖率：
func TestSomething(t *testing.T) {
if coverage.Cmd == nil {
t.Skip("coverage not enabled")
}
defer coverage.Stop()
// ...
}实战案例：
一个简单的添加函数：
func Add(a, b int) int {
return a + b
}单元测试：
func TestAdd(t *testing.T) {
tests := []struct {
input []int
expected int
}{
{[]int{1, 2}, 3},
{[]int{-10, 10}, 0},
{[]int{0, 0}, 0},
}
for _, test := range tests {
output := Add(test.input[0], test.input[1])
if output != test.expected {
t.Errorf("Expected %v, got %v", test.expected, output)
}
}
}
