Avocado can be integrated into Azure pipeline to validate OpenAPI spec repository. For example, Avocado is used by Azure/azure-rest-api-specs now that will trigger automatically by azure DevOps pipeline when a new pull request is created.

Avocado major functions are listed below:

• For a given directory validate whether exists specification and filter readme.md under the specification folder.
• Validate whether readme.md is autorest specific file which must contain see https://aka.ms/autorest
• Validate whether swagger file is valid json file, and check all referenced json file (referenced json file marked in json object has the key name "$ref").
• Validate whether the folder has any files without being referenced. swagger file must be referenced by readme.md or other swagger file.
• Validate whether swagger file has a circular reference and report a warning. For more detail, see CIRCULAR REFERENCE
• Validate whether each RP folder contains readme file for SDK generation.

How to use

Install

npm install -g @azure/avocado

Example

• Run all specs: Clone the repo azure/azure-rest-api-specs and run "avocado" in folder azure/azure-rest-api-specs.
• Run single service specs: create a folder specification. and move your service specs folder in specification. run "avocado"

How to solve errors

JSON_PARSE

Level: ERROR

To solve json parse error, you need make sure the json format is valid.

NO_JSON_FILE_FOUND

Level: ERROR

Readme file references a non-existing json file. To solve the error you need to check whether the json file is existing.

UNREFERENCED_JSON_FILE

Level: ERROR

Json file must be referenced by the readme input file section or other json files. Eg, example swagger file should be referenced by main swagger json and for SDK generation main swagger should be referenced by the readme input file section. To solve the error you need to place the non-referenced file to proper place.

MISSING_README

Level: ERROR

Each resource provider folder must have a readme file which is required by downstream SDK generation. To solve the error, you need create a readme file contains SDK generation config.

NOT_AUTOREST_MARKDOWN

Level: ERROR

Each readme in resource provider folder should follow autorest markdown format. To solve the error, you need check the readme block quote whether contains see https://aka.ms/autorest literally.

INCONSISTENT_API_VERSION

Level: ERROR

Swagger json file api version must consistent with its file path. Swagger can define swagger 2.0 basic-structure which contains api version. To solve the error, you need modify either your swagger file location or swagger file api version to make both of them consistent.

CIRCULAR_REFERENCE

Level: WARNING

To solve circular reference, you should break the circular chain.

Example: a.json -> b.json->c.json

// a.json
{ "$ref": "b.json" }

// b.json
{ "$ref": "c.json" }

// c.json
{ "$ref": "a.json" }

graph TD

A((a.json))-->B((b.json))
B-->C((c.json))
C-->A

MULTIPLE_API_VERSION

Level: WARNING

The default tag should contain only one API version swagger.

To solve this warning , you should copy the swaggers of old version into the current version folder.
