xxxTests-Info.plist Error in Xcode(删除test target)

I keep getting this error in Xcode and it's highly confusing: 

error: could not read data from '/Users/mjz/Desktop/xxx-iOS-BTv3/xxxTests/xxxTests-Info.plist': The file “(myapp)Tests-Info.plist” couldn’t be opened because there is no such file. 

when I go to my targets and find this "test" , it won't let me delete it. 

how to delete it ?

1、选择Edit Scheme

2、此时会发现，在build标签下有2个target，其中一个就是同名的Tests target，注意此时是无法直接删除Tests target的（下面的减号是不可点击的）

3、选中Test标签，选中Tests target，点击减号，将该target删除

4、此时可以看到，build标签下已经自动将Tests target移除，清爽了～

5、随后便可以肆无忌惮的删除项目内所有包含Tests的内容，一身清爽～

6、删除完毕之后，编译通过～
