This guide describes conceptual information about data design environment components when you want to use the data fabrication feature in HCL OneTest™ Server.
A schema is a graphical data dictionary that contains metadata definitions of the structure of a document to generate test data. Schema provides visual cues for understanding the structure and complete definition of an object.
You add a file to a project to use it as input in the project. You can upload a file from your local file system to a project from the Files tab to generate test data. Alternatively, you can upload it when you define an action.
A connection defines the properties that are required to connect to an external resource. An action uses a connection to provide source data to a project or write data from a source to a target. Multiple actions can use the same connection. You can define both connections and actions at the project level.
Use the Schemas tab to define, modify, and view schemas. A schema describes the syntax, structure, and semantics of your data.
The properties of a type define the characteristics of the data objects of that type.
Item restrictions are an optional feature you can use to specify valid or invalid data objects for an item type. Item restrictions are grouped into three categories: Value, Character, and Range.
The RANDDATA function returns random text based on the properties of the output type. The RAND function returns a pseudo-random integer between 0 and RAND_MAX (guaranteed to be at least 32,767). The RANDDATA function generates a valid random value of the item type that is being built when it is invoked.
The SEED function primes the RAND and RANDDATA functions so they produce repeated results.
