fixture-generator

fixture-generator provides an easy way to generate fixtures for Go structs. It aims to reduce the time one spends writing tests. It works using a "best effort" approach - if we can't generate data for a field then ignore it and return a partally complete fixture.

I do have more time to spend on this project so if you have suggestions or any kind of feedback I am more than happy to hear it and implement it as soon as possible.

Installation

go get github.com/tiriplicamihai/fixture-generator/.../, then $GOPATH/bin/fixturegen

Examples

Consider we have the next struct:

package test

type Person struct {
        Name             string
        Age              int
        Friends          []string
}

Run: fixturegen -struct Person and the following will be output to stdout:

Person{
	Name: "QuZNvyPcKeEp",
	Age: 651906,
	Friends: []string{"GMV", "dKFjsoGexcbs", "cC"},
}

Tip: You can use fixturegen -struct Person | gofmt to get a formatted fixture.

Command Line Arguments

• struct - required argument, expects the struct name for which the fixture will be generated

Fixtures can be generated even if field types are from other packages. It performs a recursive discovery for the types it finds in a package.

Known Limitations

• Fixtures can not be generated for fields declared as interfaces because we can't know the actual type
• Fixtures can not be generated for a struct that has a self referencing field (we would go in an infinite loop)
• Types from vendored external packages are not supported for now
