Test Author Guide
This guide describes how to create test assets in Rational® Test Automation Server and publish test assets to the Git repository that you have configured. This guide is intended for testers and test managers.
Generation of test data
To test an application, you use data that is passed to get real-time results. Since creating test data manually is time-consuming, you can use HCL® OneTest™ Data, an automated tool to generate random test data. You can generate the test data in various file formats.
Schema design overview
When you compose a schema by using HCL® OneTest™ Data you must define the types of the schema. You can also modify the types of the schema when you import any schema from local file system or use the schema generated by using any external resource.
Setting type properties
After you add types to your schema, you must set type properties.
Setting regular expressions
When you want values of an item type to appear in a certain pattern in the generated test data, you must set the Regular Expression property for that item type in a defined schema.

- Datasets overview
  A dataset provides tests with variable data during a run. The test that uses a dataset at run time replaces a value in the recorded test with variable test data that is stored in the dataset.
- Generation of test data
  To test an application, you use data that is passed to get real-time results. Since creating test data manually is time-consuming, you can use HCL® OneTest™ Data, an automated tool to generate random test data. You can generate the test data in various file formats.
  - Schema fabrication
    A schema is a graphical structure to represent different types of data. You can fabricate a schema for the generation of test data.
  - Schema design overview
    When you compose a schema by using HCL® OneTest™ Data you must define the types of the schema. You can also modify the types of the schema when you import any schema from local file system or use the schema generated by using any external resource.
    - Defining types
      For optimum test data generation, you must define entire data of schema into types. Types are the components of schemas. After you design schema in the schema designer, you must define entire data as types by using type designer.
    - Setting type properties
      After you add types to your schema, you must set type properties.
      - Value assignation for item types
        When you want to use specific item type values to generate the test data, then you can assign those values to the item types. To assign the values to any item type, you can either import the item type values or add the values manually.
      - Setting weightage values
        You can set weightage values for an item type to determine how often the value of that item type can be displayed in the generated test data.
      - Setting regular expressions
        When you want values of an item type to appear in a certain pattern in the generated test data, you must set the Regular Expression property for that item type in a defined schema.
      - Integrating sample files into a schema
        When you want to generate the test data, you must define a schema. HCL® OneTest™ Data provides sample files with item type values so that you can integrate the sample file into a schema by mapping it to any item type.
      - Adding JavaScript rules
        When you have a JavaScript file with defined rules to create values for any item type, then you can add the JavaScript rules to create the values for the mapped item type.
      - The pairwise data generation method
        When you test any application, you might want to ensure that the test data that you use covers all possible combinations of item type values. To achieve this goal of maximum coverage of all possible scenarios, you must apply the pairwise data generation method on the required item types of a schema.
    - Designing a structural view of a schema
      To define how the item and group types are organized and are related to each other, you must design the structural view of a schema before generating the test data.
    - Setting restrictions
      When you define any item type for a schema, you can specify valid values to that type. You can define validations to the types by setting the restrictions.
    - Applying functions
      You can apply functions on the item types of a schema to define the component rules.
  - Test data generation from structured schemas
    When you want to test your application by using randomly generated test data, then you must generate the test data from the structured schemas.
  - Status of generated test data
    You can view the status of all the test data generated jobs performed in your project, on the Jobs page.

Setting regular expressions

When you want values of an item type to appear in a certain pattern in the generated test data, you must set the Regular Expression property for that item type in a defined schema.

Before you begin

You must have logged in to Rational® Test Automation Server.
You must have created a project and a schema.

About this task

The regular expression is a special text to describe a pattern. For example, you can specify regular expressions for email address, phone number, or website. HCL® OneTest™ Data provides you some sample regular expressions.

To set regular expressions to any item type, you can either insert a value or select from the sample list of regular expressions that best suits your testing requirements. HCL® OneTest™ Data then validates the value you inserted for the Regular Expression field and generates the values of the selected item type in a similar pattern.

Procedure

Select your project in HCL OneTest Server and go to the Data Fabrication page.
Open your schema from the Schemas tab.
Select the item type for which you want to set regular expressions.
Click Regular Expression from the Properties dialog box.

The sample list of regular expressions is displayed.
Set the regular expression in the Regular Expressions field by using any one of the following methods:
- Type the regular expression. HCL® OneTest™ Data then validates the regular expression.
  For example, [0-9]{18}
  Tip: If you want to reuse the validated regular expression then click Add to sample list, to add the expression in the list.
- Select the regular expression from the sample list. The selected regular expression is displayed in the Regular Expressions field.
Click Save.

Results

You have successfully set the regular expression for the selected item type.

What to do next

You must prepare the structural view of the schema. See Designing a structural view of the schema.
