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.
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.
Assigning values for item types from a file
When you have a file with values for an item type on your computer then you can assign those values to the item type to generate the test data.

- 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.
        Assigning values for item types from a file
        When you have a file with values for an item type on your computer then you can assign those values to the item type to generate the test data.
        Inserting values for item types manually
        When you want to assign specific values to an item type that does not exist in any file on your computer, then you can assign those values by inserting 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.

Assigning values for item types from a file

When you have a file with values for an item type on your computer then you can assign those values to the item type to generate the test data.

Before you begin

You must have created a file with item type values on your computer.

Procedure

Select your project in Rational® Test Automation Server and go to the Data Fabrication page.
Click Files and import the file of item type values from your computer into your project.
Open your schema from the Schemas tab.
Select the item type for which you want to assign the values.
Select Restrictions from the Item Properties drop-down list of the Properties dialog box.
Enable the Values from file toggle button.
Provide the name of the file that you imported with an extension in the Values file field.
Enter the column number of the file where the item type values are specified in the Values column number field.
Save the changes.

Results

You have successfully assigned the values for item types from a file.

What to do next

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