Testing & Analysis of Shell (Bash) Scripts?

I'm working on a project where we deploy our software to Linux machines. This involves a whole load of Bash, for example, the init scripts (e.g. service foo start for SysVinit. My big concern is that we don't test these the way we test the application layer code with JUnit, FindBugs etc as part of our CI pipeline. What solutions are usually relied upon here? Is it possible to test and analyse these low level Linux scripts the way we would the app layer code?
