函数很简单,但如何测试呢,简单但丑陋的方法:
func Test_func(t *testing.T) {
isCalled := false
f := func() {
isCalled = true
}
trans := New()
// do something
trans.Do(f)
// check
if isCalled {
// do something
}
}

func Test_func(t *testing.T) {
isCalled1 := false
isCalled2 := false
isCalled3 := false
f1 := func() {
isCalled1 = true
}
f2 := func() {
isCalled2 = true
}
f3 := func() {
isCalled3 = true
}
trans := New()
// do something
trans.Do(f1)
trans.Do(f2)
trans.Do(f3)
// check
if isCalled1 {
// do something
}
if isCalled2 {
// do something
}
if isCalled3 {
// do something
}
}
