# Or run the docker image
docker run -v "$(pwd):/run" ghcr.io/vegaprotocol/approbation:latest check-references --specs="/run/specs/protocol/**/*.{md,ipynb}" --tests="/run/MultisigControl/test/*.js" --ignore="/run/specs/protocol/{0001-*}" --categories="/run/specs/protocol/categories.json" --show-branches --show-mystery --output-csv --output="/run/results/"

next-filename

Suggests what file sequence number to use next, given a list of spec files

Arguments

Parameter	Type	Description	Example
--specs	glob	specs to pull AC codes from	{specs/**/*.md}
--ignore	glob	glob of files not to include	specs/0001-spec.md
--verbose	boolean	Display extra output	-

In the case of three specs, ['001...', '002...', '003...'] this would suggest '004'. However if '002' didn't exist, it would indicate that '002' is available, as well as '004'.

next-filename example

# Use node
npx @vegaprotocol/approbation next-filename --specs="./specs/protocol/**/*.{md,ipynb}"

# Or run the docker image
docker run -v "$(pwd):/run" ghcr.io/vegaprotocol/approbation:latest next-filename --specs="/run/specs/protocol/**/*.{md,ipynb}"

next-code

Suggests what AC code to use next given a spec file

Arguments

Parameter	Type	Description	Example
--specs	glob	spec to pull AC codes from. Should only match one file.	{specs/**/0001-SPEC-spec.md}
--ignore	glob	glob of files not to include	specs/0001-spec.md
--verbose	boolean	Display extra output	-

Like next-filename, next-code will suggest the lowest available code in the sequence (e.g. if there is 0001-SPEC-001 and 0001-SPEC-003), it will suggest both 0001-SPEC-002 and 000-SPEC-004. If using the lowest available code, ensure it isn't already referenced by any tests (i.e. isn't listed as a 'Mystery Criteria' by check-references).

next-code example

# Use node
npx @vegaprotocol/approbation next-filename --specs="./specs/protocol/**/*.{md,ipynb}"

# Or run the docker image
docker run -v "$(pwd):/run" ghcr.io/vegaprotocol/approbation:latest next-filename --specs="/run/specs/protocol/**/*.{md,ipynb}"

Background

Each protocol specification receives a sequence number when it is merged in to master. This sequence number is a 0-padded integer, strictly 1 greater than the last merged specification. The sequence number is the start of the filename, with the end result that the ./protocol/ folder lists files in the order they were created.

After the sequence number, separated by a -, is a 4 letter code. This is arbitrary, and can be made up at merge time. It's there as a helpful hint as to what spec 0001 is, rather that having to keep that in mind.

The end result is that every specification (.md or .ipynb) should be named something like:

0024-EXMP-example-specification

Acceptance Criteria codes

Acceptance Criteria codes use the first two parts of the filename (detailed above), and then another sequence number (this time, 0 padded to 3 characters). These are assigned to each specific acceptance criteria that should be validated by a test (in any test suite.l)

The result

The result of the rules above is that we can easily map which acceptance criteria are covered in which test suite, and what our coverage for the main features identified in specs are. This is the task that these scripts solve.

How to name a spec

1. When your pull request is ready to merge, take a look at the most recent sequence number in the protocol folder. Maybe the last spec was 0088-BLAH-example.md. Your sequence number is 0089.
2. Now, make yourself a code based on the filename. It should be unique, and it should be memorable, so for example if the spec is system_accounts.md, it could be 'SYSA', or 'SYAC' - whatever feels reasonable.
3. Rename your file to 0088-SYSA-system_accounts.md
4. Label the acceptance criteria 0088-SYSA-001, 0088-SYSA-002 and so on.
5. Merge!

How to reference acceptance criteria in a spec.

These are more convention than a rule, but following these steps will ensure that the scripts in this folder pick up your references.

1. When you are writing your feature, take a look at the acceptance criteria.
2. If you're addressing one, reference it at the end of the Feature name, for example if you are writing a test that covers 0008-SYSA-001, call the feature Verify blah (0008-SYSA-001)
3. If it covers more than one feature, add it inside the same brackets: Verify blah (0008-SYSA-001, 0008-SYSA-002)
4. If a feature test intentionally covers something that isn't explicitly an acceptance criteria you can signal this with 0008-SYSA-additional-tests

Development

Run npm run setup to configure your environment:

• Tests should be run pre-push
• Package is published to npm on tag

Use in CI

# Use the pre-packaged docker version
