Go服务自动触发单元测试覆盖率

一、用到的工具

Gitlab
Jenkins
Shell
go test

二、实现原理

在gitlab上配置jenkins的webhook，当有代码变更时自动触发jenkins构建job，job内的shell脚本负责把覆盖率报告以钉钉群通知的方法发送出去。

三、Jenkins job配置

点击上图中的“高级”，出现下图后，点击“Generate”，生成Secret token。

四、Gitlab配置webhook

五、Shell脚本

touch last_num.txt

#存储本次.go文件和_test.go文件的个数，作为上次数据
echo $this_time_go_num > ./this_time_go_num.txt
echo $this_time_test_go_num > ./this_time_test_go_num.txt
echo $this_time_per > ./this_time_per.txt

#获取上次的.go文件数，如果没有则创建文件
if test -e last_time_go_num.txt
then
last_time_go_num=$(cat last_time_go_num.txt)
echo $last_time_go_num
else
touch last_time_go_num.txt
fi

#获取上次的test.go文件数，如果没有则创建文件
if test -e last_time_test_go_num.txt
then
last_time_test_go_num=$(cat last_time_test_go_num.txt)
echo $last_time_test_go_num
else
touch last_time_test_go_num.txt
fi

#获取上次的per，如果没有则创建文件
if test -e last_time_per.txt
then
last_time_per=$(cat last_time_per.txt)
echo $last_time_per
else
touch last_time_per.txt
fi

#计算两次.go文件数的差
go_num_diff=`expr $this_time_go_num - $last_time_go_num`
echo $go_num_diff

#计算两次test.go文件数的差
test_go_num_diff=`expr $this_time_test_go_num - $last_time_test_go_num`
echo $test_go_num_diff

#计算两次占比的差
this_time_test_go_num_init=$(printf "%d" $(($this_time_test_go_num*100/$this_time_go_num)))
last_time_test_go_num_init=$(printf "%d" $(($last_time_test_go_num*100/$last_time_go_num)))
per_diff=$(printf "%d%% " $(($this_time_test_go_num_init-$last_time_test_go_num_init)))
echo $per_diff
