背景
有时候我们在写代码是，需要将test编译成单独的可执行文件进行测试，并且在test中传参。
go version
go version go1.15.1 darwin/amd64
demo
package action
import (
"flag"
"fmt"
"testing"
)
var cc = flag.String("cc", "11", "")
func TestInit2(t *testing.T) {
flag.Parse()
}
func TestWildDomain(t *testing.T) {
fmt.Println("cc:", *cc)
}
测试
go test t_test.go -cc=222 -v
=== RUN TestInit2
--- PASS: TestInit2 (0.00s)
=== RUN TestWildDomain
cc: 222
--- PASS: TestWildDomain (0.00s)
PASS
ok command-line-arguments 0.615s
go test t_test.go -cc=11 -v
=== RUN TestInit2
--- PASS: TestInit2 (0.00s)
=== RUN TestWildDomain
cc: 11
--- PASS: TestWildDomain (0.00s)
PASS
ok command-line-arguments 0.223s
./action.test -cc=1120 -test.v
=== RUN TestInit2
--- PASS: TestInit2 (0.00s)
=== RUN TestWildDomain
cc: 1120
--- PASS: TestWildDomain (0.00s)
