FAST Permutator
FAST Permutator has been deprecated. Use FAST Tooling React instead.
The FAST permutator creates all possible data permutations from a given JSON Schema, allowing for deep testing or display of complex data sets.
Use
Including the permutator
Add the permutator as a required variable:
const permutator = require('@microsoft/fast-permutator');
Permutating data sets
The main export of the permutator is to recieve a schema and any schema references. For example, take this simple schema:
let schema = {
type: "object",
properties: {
stringItem: {
type: "string",
example: "Hello World"
},
booleanItem: {
type: "boolean"
}
},
required: [
"stringItem"
]
};
permutator(schema);
This main export permutator will generate the following data:
[
{
stringItem: "Hello World"
},
{
stringItem: "Hello World"
booleanItem: true
},
{
stringItem: "Hello World"
booleanItem: false
}
]
If an example or a default is not provided, fake data will be generated.
Exporting an example
Use the export getExample
to retrieve an example piece of data.
permutator.getExample(schema);
Simplifying schemas
Use the export simplifySchemas
to show all schema permutations. This can be useful for extrapolating out all possible schema combinations.
permutator.simplifySchemas(schema, references);
Finding properties
Use the export getDeepPropLocations
to find properties within the schema.
permutator.getDeepPropLocations(schema, propertyName);
Resolve references
Use the export resolveReferences
to resolve the references of a schema by consolidating them with their referenced schema.
permutator.resolveReferences(schema, references);
Resolving properties
Use the export resolveSchemaProps
to resolve the given props for a schema.
permutator.resolveSchemaProps(schema, ['$ref', 'allOf']);
