Manual generates unit test fixtures and Go model objects from an OpenAPI 2.0 spec.
See Example folder for an example of an input spec and output test fixtures / Go models.
Why is this awesome?
This tool enables teams to keep their API in sync between servers and clients by using a single source of truth. This is achieved by having a server utilize generated Go model objects and clients write unit tests against the generated test fixtures.
When using this tool it is recommended that the team keeps a repository where the spec, the generated fixtures, and generated Go model objects can reside which is reviewed by all teams. The mobile clients only need to import the test fixtures while the server engineers only need to import the Go model package.
Manual supports unique OpenAPI 2.0 features like:
- abstract model schemas (generated as interfaces in Go) using
- representing polymorphism using the discriminator and
- nullability using
- specs with external file refrences to model schemas
You can use ManualReaderObjC to easily manage your generated fixtures in your iOS project. ManualReaderObjC makes it easy to stub requests/responses, parse fixtures into a type safe object, and pull out JSON examples of defined objects to test model object parsing in your unit tests.

$ manual --help Usage: manual -i [input] [flags] Flags: -f, --fixtures string Generates test fixtures in the provided output directory. -g, --go-models string Generates Go models in the provided output directory. -p, --go-package-name string Specifies the name of the generated Go package. Defaults to Go models\' output directory name. -i, --input string The input Swagger JSON specification file. (required)
Generate test fixtures and Go models using an OpenAPI 2.0 spec as an input.
$ manual --input "~/api/spec/index.json" --fixtures "~/api/gen_files/fixtures" --go-models "~/api/gen_files/models"
You'll need MacOS 10.13+ (High Sierra) and to have the Xcode 9.2+ command line tools installed.
$ mint run n8chur/Manual
$ manual --help
Running the tests
Tests must be run on macOS 10.13 (High Sierra) and above since the validation JSON fixtures are generated with .sortedKeys which is only supported by macOS 10.13 and above.
$ make test
