英文:
Capture SIGINT when running tests in GoLand IDE
问题
当从命令行运行测试时，捕获SIGINT信号是有效的。但是，当从GoLand IDE运行测试时，有没有办法将SIGINT信号传递给代码呢？
当从命令行运行时：
go test -v -run TestSth，然后调用<kbd>Ctrl + C</kbd>，它可以正常捕获。
示例代码：
编辑：看起来我的示例代码现在可以按预期捕获SIGINT信号（Goland 2022.3.2）
package main
import (
"fmt"
"os"
"os/signal"
"syscall"
"testing"
"time"
)
func TestMain(m *testing.M) {
terminate := make(chan os.Signal)
signal.Notify(terminate, syscall.SIGINT)
go func() {
<-terminate
fmt.Println()
fmt.Println("CAPTURED!!!") // 当从IDE运行测试时，希望能到达这里
}()
exitCode := m.Run()
os.Exit(exitCode)
}
func TestSth(t *testing.T) {
time.Sleep(time.Second * 5)
}
英文:
When running tests from command line, capturing SIGINT works fine. However, is there a way to pass SIGINT signal to code when running tests from GoLand IDE?
When running from command line:
go test -v -run TestSth and then calling <kbd>Ctrl + C</kbd> it captures fine.
Example code:
EDIT: it seems my example code now captures SIGINT as intended (Goland 2022.3.2)
package main
import (
"fmt"
"os"
"os/signal"
"syscall"
"testing"
"time"
)
func TestMain(m *testing.M) {
terminate := make(chan os.Signal)
signal.Notify(terminate, syscall.SIGINT)
go func() {
<-terminate
fmt.Println()
fmt.Println("CAPTURED!!!") // want to get here when running tests from IDE
}()
exitCode := m.Run()
os.Exit(exitCode)
}
func TestSth(t *testing.T) {
time.Sleep(time.Second * 5)
}

通过调用FindProcess函数获取当前进程的信息，并使用Process.Signal向其发送中断信号。
func TestSth(t *testing.T) {
go func() {
// 为了演示目的添加了Sleep，可以删除
time.Sleep(time.Second * 1)
p, err := os.FindProcess(os.Getpid())
if err != nil {
panic(err)
}
p.Signal(syscall.SIGINT)
}()
time.Sleep(time.Second * 5)
}
英文:
Get the current process information by calling FindProcess on the current PID and signal the interrupt to it using Process.Signal
func TestSth(t *testing.T) {
go func() {
// Sleep added for demonstrative purposes, can be removed
time.Sleep(time.Second * 1)
p, err := os.FindProcess(os.Getpid())
if err != nil {
panic(err)
}
p.Signal(syscall.SIGINT)
}()
time.Sleep(time.Second * 5)
}
