`shellFunctionSetup.sh` - Add Unit Test Coverage of `shellFunctionSetup.sh`

[ReedClanton]

Overview

Add ShellSpec unit test coverage for the shellFunctionSetup.sh file.

Details

Add ShellSpec unit tests for the shellFunctionSetup.sh file. Unit tests should be written for all supported shells.

All unit tests must be run by the pipeline.

Ensure that the result of these unit tests are reflected in the GitHub status badge(s) in the top level README.md of this repository.

The new unit tests should be documented to the same level as the existing ones.

Supported Shells

• bash
• zsh
• dash
• BusyBox ash
• FreeBSD sh
• NetBSD sh
• mksh
• OpenBSD ksh
• yash
• posh
• OSH

Artifact(s)

• PR that adds unit test coverage of shellFunctionSetup.sh and ensures that the tests are run by the pipeline, if it exists.

Scope

At point of writing, I don't know how many of the supported shells are already supported by the unit test suit. If a shell is not already supported by the unit test suit, then break out the creation of unit tests of shellFunctionSetup.sh for that shell into a separate issue.

If issue #3 hasn't already been worked, then there will be no pipeline. In that case, there is no need to add these unit tests to the pipeline.

If issue #4 hasn't already been worked, the there is no need to do this. If issue #4 has been worked, but #5 hasn't, then this only needs to be done for the zsh status badge.

Blockers

Before this issue may be worked, ShellSpec unit tests must have already been added by issue #2.

Should be worked after issue #3 and #4.
