Reference Guide
This guide describes conceptual information about data design environment components when you want to use the data fabrication feature in HCL OneTest™ Server.
- Files
  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.
- Connections
  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.
- Schema design
  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.
  - Introduction to schema design
    Use the Schemas tab to define, modify, and view schemas. A schema describes the syntax, structure, and semantics of your data.
  - Type properties
    The properties of a type define the characteristics of the data objects of that type.
  - Item restrictions
    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.
  - Components
  - Partitioning
  - Type inheritance
  - Schema analyzer
  - Distinguishable objects
  - Functions and expressions

IF

You can use the IF function for conditional logic. For example, to return one of two objects depending on the evaluation of a condition.

IF evaluates a conditional expression, returning one value if true, another if false.

Syntax:: IF (single-condition-expression , single-general-expression
[ , single-general-expression ])
Meaning:: IF (test_this , result_if_true [ , result_if_false ])
Returns:: A single item or single group

If test_this evaluates to "true", the result is result_if_true.

Otherwise, if test_this evaluates to "false", the result is result_if_false. If no result_if_false is specified, this evaluates to "none".

The result_if_true and result_if_false arguments must correspond to the same item interpretation or the same group type or either can be "none". For example, if result_if_true evaluates to a number, result_if_false must also evaluate to a number. If result_if_true evaluates to a LineItem group, result_if_false must also evaluate to a LineItem group.

Examples

IF (Quantity:LineItem:PO > 500, "PRIORITY", "REGULAR")
This example tests the Quantity value. If that Quantity is > 500, the IF function evaluates to the value PRIORITY. If that Quantity is <= 500, the IF function evaluates to the value, REGULAR.
IF (Status:Order = "Special", "SPCL")
This example tests the Status value. If the Status is Special, the IF function evaluates to the value, SPCL. Otherwise, it evaluates to "none". Notice that this rule is equivalent to

IF (Status:Order = "Special", "SPCL", "none")
