Setting the pairwise data property
When you want to generate an optimum test data that covers all possible combinations of item type values for each pair of item types in a schema, you can set the pairwise data property for those item types.
Before you begin
- Created a schema in HCL® OneTest™ Data.
- Read the details about how to assign the values to an item type. See Value assignation for item types.
About this task
The pairwise data generation method is a combinational method to find all the possible values of the selected pairs of item types. The pairwise data generation method is efficient when you have a large number of item types and the item type values in a schema. When you apply the pairwise data generation method in such cases, the number of generated test data decreases drastically although covering all the combinations. To implement the pairwise data generation method, you must have multiple item types in a group type of a schema. To assign item type values, you must either import the values of item type from a file or insert values for each item type.
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 from Dictionary for which you want to set the pairwise data property.
- Select Restrictions from the Item Properties drop-down list of the Properties dialog box.
-
Set values for the selected item type by using any one of the following
methods:
- Import item type values from the file by using Values from file.
- Include values for the selected item type in the Properties dialog box.
- Save the changes.
- Select Item Properties from the drop-down list of the Properties dialog box.
- Click the Advanced Properties icon .
-
Select Yes from the Pairwise Data
drop-down list.
Note: The default value of the Pairwise Data drop-down list is No.
-
Save the changes.
Important: You must select multiple item types to apply the pairwise data generation method.Note: When you want to apply the pairwise data generation method for each item type, you must repeat step 4 through step 10.
Results
You have successfully set the pairwise data property for the selected item type.
What to do next
You must select a group type to generate the test data of a schema. See Generating test data.
