System Requirements
This document includes information about hardware and software requirements for HCL OneTest™ Server.
Getting Started Guide
This guide provides an overview of HCL OneTest™ Server. You can find the task flows to get you started with HCL OneTest Server. This guide is intended for new users.
Administrator Guide
This guide describes how to install the HCL OneTest™ Server software.
Test Author Guide
This guide describes how to create test assets in HCL OneTest™ Server and publish test assets to the Git repository that you have configured. You can also edit existing test assets that are in the repository added to your project. This guide is intended for testers and test managers.
Test Execution Specialist Guide
This guide describes tasks that you must complete before you can configure and run tests in HCL OneTest™ Server. You can find information about configuring runs for the different test types that are supported. You can also find information about other tasks that you can perform on the Resource Monitoring Service, Virtualization, and Integrations with third-party applications. This guide is intended for testers or test execution specialists.
Test Manager Guide
This guide describes how to manage and track your overall test effort. This guide is intended for test managers.

- 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

UNPACK

You can use the UNPACK function to do arithmetic with a packed decimal number or to move a packed decimal value into a numeric item.

UNPACK converts text that can be interpreted as a packed decimal number to a signed integer item.

The sign values for packed data are as follows:

C for positive (+)
D for negative (-)
F for unsigned, which is read as positive

Syntax:

UNPACK ( single-fixed-size-text-expression )

Meaning:

UNPACK ( text_to_unpack )

Returns:

A single signed integer

UNPACK returns a signed integer representing the value text_to_unpack, which is a packed decimal number. If the text_to_unpack cannot be interpreted as a valid packed decimal, UNPACK evaluates to "none".

In a packed decimal number, each half-byte is a digit, except for the last half-byte of the rightmost byte, which contains a sign.

Examples

UNPACK ( "1L" ) returns 314
The ASCII string "1L" in hex is 31 4C, which, when interpreted as a packed number, results in (positive) 314. This example returns the value "+314".

The hexadecimal representation of the value "1L" is x`14C', where C in the rightmost half-byte represents a positive sign.
UNPACK ( UnitPrice ) / 100 * QuantityOrdered
UnitPrice is unpacked and divided by 100 (to convert it from an integer to a number with two decimal places) and then multiplied by the QuantityOrdered.

You can define items as having a packed decimal number presentation. Then, when mapping to or from these items, the conversion to and from packed decimal is automatically performed as needed.
