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.
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.
Generated test data for an Excel file
When you use Microsoft Excel as a database in your application testing environment and you want to use the structure of an Excel file to generate test data, then you can generate the test data for the selected Excel file by using HCL® OneTest™ Data.
Generating test data by using the generated schema
After you generate the schema in HCL® OneTest™ Data, you can use this schema to generate the test data in HCL OneTest 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.
  - 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.
    - Generated test data in JDBC database
      When you want the generated test data in any Java Database Connectivity (JDBC) supported database, you can generate the test data by using HCL® OneTest™ Data. Subsequently, HCL OneTest Data inserts the generated test data directly in the configured JDBC supported database.
    - Generated test data for SAP IDoc or DXOB
      When you want to generate the test data for an SAP Intermediate Document (IDoc) or Data Transfer Object (DXOB) file, you can generate a schema in HCL® OneTest™ Data by using the structured schema of the SAP IDoc or DXOB file. You can then generate the test data by using the generated schema in HCL OneTest Data.
    - Generated test data for SAP BAPI
      When you want to generate test data for SAP Business Application Programming Interface (BAPI), you can generate a schema in HCL® OneTest™ Data based on structured schema of SAP BAPI function modules. You can then generate the test data by using the generated schema in HCL OneTest Data.
    - Generated test data in MongoDB
      When you use MongoDB as a database in your application testing environment and you want the generated test data in MongoDB, then you can generate the test data by using HCL® OneTest™ Data. Subsequently, HCL OneTest Data inserts the generated test data directly in MongoDB.
    - Generated test data for an Excel file
      When you use Microsoft Excel as a database in your application testing environment and you want to use the structure of an Excel file to generate test data, then you can generate the test data for the selected Excel file by using HCL® OneTest™ Data.
      - Importing an Excel file
        When you want to establish a connection between HCL® OneTest™ Data and an Excel file, you must import the Excel file into your HCL OneTest Data project from your computer.
      - Establishing a connection between HCL OneTest Data and Excel
        When you want to generate a schema based on an Excel file, you must establish a connection between HCL® OneTest™ Data and Excel.
      - Generating a schema based on an Excel file
        After you establish the connection between HCL® OneTest™ Data and Excel, you can generate a schema that is based on an Excel file in HCL OneTest Data.
      - Generating test data by using the generated schema
        After you generate the schema in HCL® OneTest™ Data, you can use this schema to generate the test data in HCL OneTest Data.
    - Generating test data
      When you have a defined and structured schema for the entire data, you can generate test data to perform application testing.
  - 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.

Generating test data by using the generated schema

After you generate the schema in HCL® OneTest™ Data, you can use this schema to generate the test data in HCL® OneTest™ Data.

Before you begin

You must have generated the schema by using the connection that is established between HCL® OneTest™ Data and Excel. See Generating a schema based on Excel file.

Procedure

Select your project in Rational® Test Automation Server and navigate to the Data Fabrication page.
Select the schema name schema_<number> from the Schemas tab.
The schema is displayed.
Select the Sheet group type, and then select Structure from the menu.

You can view a group as Row in the structure of the schema. All item types of a schema are listed under the Row group type.
Click the menu for the Row group type, and then set the property as Set Required.
Click the menu for all the item types that you want to use to generate the test data, and then set the property as Set Required.

Note: If you have a numeric item type, you must set Min size (digits) and Max size (digits) properties.

For example, when you select Integer as Presentation, then you can set the Min size (digits) as 1 and the Max size (digits) as 9.
Click Save.
Select the Sheet group type in the Dictionary dialog box, and then click Generate Data from the menu.

The Generate Data dialog box is displayed.
Provide the number of records that you want to generate in Number of records.
Optional: Provide a seed value that acts as a reference number to generate the same set of data in Numeric Seed Value.
Select the output file format for the generated test data from the list, and then click OK.

Results

You have successfully generated the test data by using the generated schema.

What to do next

You can click the Jobs tab to view the status of the job. You can then download the generated test data of the jobs that are completed successfully.
