ayaml-go

ayaml-go is imported from Ayaml

ayaml-go gives you factory-girl like DSL to build test data.

Note that ayaml-go doesn't build test data as it is. Connection to database should be delegated to the other codes. (this is why this library is simple and flexible

sample

build data from below yml

valid_user:
  id: 100000000
  name: UserName
  created: '2014-01-01T00:00:00Z'

a, _ := ayaml.New("./your_fixture.yml")


data, _ := a.Schema("valid_user").Dump()
data == SchemaData{
	"id":      100000000,
	"name":    "UserName",
	"created": "2014-01-01T00:00:00Z",
}

data, _ = a.Schema("valid_user").With(SchemaData{"id": 1}).Dump()
data == SchemaData{
	"id":      1,
	"name":    "UserName",
	"created": "2014-01-01T00:00:00Z",
}

build sequential data

a, err := ayaml.New("./your_fixture.yml")
if err != nil {
	t.FailNow()
}

user := a.Schema("valid_user")

// increment id.
data, _ := ayaml.Seq(user).Range("id", 10, 12).ByOne().Dump()
data == []SchemaData{
	{
		"id": 10,
		"name": "UserName",
		"created": "2014-01-01T00:00:00Z",

// decrement id.

		"name": "UserName",
		"created": "2014-01-01T00:00:00Z",

// increment date string.
// you can specify duration 'byDay','byWeek','byMonth','byYear','bySecond'
