golang单元测试
在$GOPATH的src目录下建目录demo_unittest
在目录demo_unittest下建文件calc.go,内容如下:
package demo_unittest
func Add(a, b int) int {
return a + b
}
func Sub(a, b int) int {
return a - b
}
func Mul(a, b int) int {
return a * b
}
func Div(a, b int) int {
return a / b
}在目录demo_unittest下建文件tests/calc_test.go内容如下
package tests
import (
"demo_unittest"
"testing"
)
func TestAdd(t *testing.T) {
result := demo_unittest.Add(1, 2)
if result != 3 {
t.Errorf("TextUrl was incorrect, got: %d, want: %d.", result, 3)
}
}
func TestSub(t *testing.T) {
result := demo_unittest.Sub(1, 2)
if result != -1 {
t.Errorf("TextUrl was incorrect, got: %d, want: %d.", result, -1)
}
}
func TestMul(t *testing.T) {
result := demo_unittest.Mul(1, 2)
if result != 2 {
t.Errorf("TextUrl was incorrect, got: %d, want: %d.", result, 2)
}
}
func TestDiv(t *testing.T) {
result := demo_unittest.Div(4, 2)
if result != 2 {
t.Errorf("TextUrl was incorrect, got: %d, want: %d.", result, 2)
}
}在目录demo_unittest/tests下建文件calc1_test.go内容如下
package tests
import (
"demo_unittest"
"testing"
)
func TestAdd1(t *testing.T) {
result := demo_unittest.Add(1, 2)
if result != 3 {
t.Errorf("TextUrl was incorrect, got: %d, want: %d.", result, 3)
}
}
func TestSub1(t *testing.T) {
result := demo_unittest.Sub(1, 2)
if result != -1 {
t.Errorf("TextUrl was incorrect, got: %d, want: %d.", result, -1)
}
}
func TestMul1(t *testing.T) {
result := demo_unittest.Mul(1, 2)
if result != 2 {
t.Errorf("TextUrl was incorrect, got: %d, want: %d.", result, 2)
}
}
func TestDiv1(t *testing.T) {
result := demo_unittest.Div(4, 2)
if result != 2 {
t.Errorf("TextUrl was incorrect, got: %d, want: %d.", result, 2)
}
}在tests目录下执行如下命令,运行单元测试
go test -v如果只想运行某一个单元测试函数,运行如下命令
go test -v -run TestMul1 demo_unittest/tests
