echo $output >&3：将被测函数的输出打印到屏幕； - 在被测函数的 echo 语句中不使用
*，避免进行 Filename Generation（被解释成当下目录的所有文件）； -
echo "$output" >&3：必须在 bats 命令行指定 -t 参数可以起作用；

- Unit Testing bash scripts @ stackoverflow；
it's possible to import (include, whatever) a procedure (function, whatever it's named) from an external file. That's the key to writing a testing script: you break up your script into independent procedures that can then be imported into both your running script and your testing script, and then you have your running script be as simple as possible.
This method is like dependency injection for scripts, and sounds reasonable.
