如何按指定列内容分组重排CSV文件？Golang优化实现咨询

我是Golang新手，现在需要实现按CSV文件最后一列（状态值为passed、failed、skipped）的内容进行分组重排的功能。目前已经写出了能正常运行的代码，但觉得这个方案不够优雅高效，附上当前代码、测试数据和运行结果，想请教有没有更优的实现方式。

原始CSV数据 #

test,test-cat,skipped
test,test-cat,failed
test,test-cat,passed
test,test-cat,skipped
test,test-cat,passed
test,test-cat,failed

预期结果 #

test,test-cat,skipped
test,test-cat,skipped
test,test-cat,failed
test,test-cat,failed
test,test-cat,passed
test,test-cat,passed

当前实现代码 #

package main
import (
        "bufio"
        "fmt"
        "os"
        "strings"
)
func main() {
        var FailStat, SkipStat,PassStat []string
      
        file, err := os.Open("test.csv")

        if err != nil {
                fmt.Println(err)
        } else {
                scanner := bufio.NewScanner(file)
                for scanner.Scan() {
                        line := scanner.Text()
                        if strings.Contains(line, "failed") {
                                FailStat = append(FailStat, line)

                        }
                        if strings.Contains(line, "skipped") {
                                SkipStat = append(SkipStat, line)

                        }
                        if strings.Contains(line, "passed") {
                                PassStat = append(PassStat, line)

                        }                       
                }
        }
        file.Close()

        var finalstat []string
        finalstat = append(SkipStat, FailStat...)
        finalstat = append(finalstat, PassStat...)

        for _, line := range finalstat {
           fmt.Println(line)
   }
}

测试运行结果 #

$ ./readfile 
test,test-cat,skipped
test,test-cat,skipped
test,test-cat,failed
test,test-cat,failed
test,test-cat,passed
test,test-cat,passed
