** TEST FAILED **

ERROR: Job failed: exit status 1

我遇到这种情况，是因为跑单元测试的时候，安装gitlabrunner的那台机器上的Xcode的模拟器(外接真机)没有被指定，在.gitlab-ci.yml文件中指定test的设备就好了，比如，我是这么写的：

// platform:指定设备类型
// id : 设备的UUID
 test_project:
   stage: test
   script:
     - xcodebuild test -project xxxxx.xcodeproj -scheme xxxxxxTests -destination 'platform=iOS,id=5015bdba5a11a63c2450xxxxbf495109cfxxxxx' | xcpretty 
   tags:
    - iOS

还可以指定模拟器，可以参考这篇文章
Destination Specifier

希望对以后遇到这个问题的人有帮助。
