Sublime 3 build system to run NPM Test

In Sublime 3,  go to `tools > build system > new build system` and paste the below into the file:

{  
 "working_dir": "${project_path:${folder:${file_path}}}",  
 "cmd": ["npm", "test"]  
}

Now you will have a build system that will run the NPM test command in your current project directory.
