Gold is a tool written in Zsh for golden testing on stdout/stderr of commands.
| All pass | One passes, one fails |

- Name test cases for easy identification in the output.
- Declarative approach, leveraging a Zsh file to provide configuration and resource files.
- Can be used to test software written in any language. The output of the binaries is what is tested.
- When a test case does not pass, the diff is nicely displayed using delta.
- Patch the golden file of test cases currently not passing.
zsh— https://zsh.sourceforge.io- In macOS this should already be installed.
delta(optional) — https://github.com/dandavison/delta

gold <config-file> <sub-command>
<config-file>
Config file path, written in Zsh, which must define the following parameters:
- `test_cases`. Numerically indexed array with the name of the test cases. This allows gold
to know how many test cases should be executed and provides a tag to print for each test.
- `resources`. Holds the file path to a dir to provide data for the command. At a minimum,
it is expected that for each test case there is one golden file in this directory with
the name `<index>_golden.txt`.
- `command`. Command to execute which output is compared against a golden file. The file can
be any valid Zsh command. Two strings are replaced before executing the command: <R> with
the `resources` value and <I> with the test case index (indices begin at 1).
<sub-command>
- list: List all test cases.
- run-all: Run all test cases.
- run <test-case-index>: Run a single test case, by index.
- execute <test-case-index>: Execute the command corresponding to a test case, by index.
- patch-all: Patch (fix with current diff output) all test cases.
- patch <text-case-index>: Patch (fix with current diff output) a single test case, by index.
For an example usage, refer to the directory test.
To run the first configuration, execute: gold test/pass_fail/config.zsh run-all.
