Usage

Akov.DataGenerator library helps to generate random data based on its internal DataScheme.

There are three main ways how the DataScheme can be obtained.

• Using json file
• Using DataGenerator.Attributes
• Using mapper profiles

The DG output for the first two can then be represented as a json string or a generic object or collection.

// Get DataScheme
DataScheme GetFromFile(string filename)
DataScheme GetFromType<T>()

// Generate data
string GenerateJson(DataScheme scheme)
string GenerateJsonCollection(DataScheme scheme, int count)
T GenerateObject<T>(DataScheme scheme)
IEnumerable<T> GenerateObjectCollection<T>(DataScheme scheme, int count)

When dealing with profiles there is no public method populating the DataScheme. Instead you can directly get the output.

string GenerateJson<T>(DgProfileBase profile)
string GenerateJsonCollection<T>(DgProfileBase profile, int count)
T GenerateObject<T>(DgProfileBase profile)
IEnumerable<T> GenerateObjectCollection<T>(DgProfileBase profile, int count)

What should you be aware of?

At this moment, object generation is literally deserialization of the built json.

Json first approach was chosen to introduce Random Failure feature. If it is enabled, then the generated json is supposed to be invalid/incorrect for some objects, and deserialization may fail unless specific error handling is added. Like in this example based on Newtonsoft.Json usage. Unfortunately, System.Text.Json doesn't support this behavior yet.
