Navigation concepts for test data

  • Article

To simplify the discoverability of generation methods for test data, a set of navigation objects is introduced. For more information about the generation methods, see Test data methods.

Navigation should start from the root object, the module must be specified, and then the entity must be specified together with the test data methods.

data.module().entity().testDataMethod();

Examples

modelGroup = data.invent().modelGroups().fifo();

itemBuilder = data.products().items().whsBuilder();

data.sales().salesOrders().ensureCanCreate();

data.invent().parameters().enableQualityManagement();

Advantages

  • Discoverability of data creation application programming interfaces (APIs). IntelliSense helps you get to the helper methods that are relevant for the entity.
  • Local references to frequently used nodes (for example, items.whsBuilder()). Therefore, long names aren't required.

Root navigation object

The root navigation object is the starting point for finding the test data methods that are required. The root navigation object exposes modules where test data methods are defined.

Variable naming

The suggested name for variables that reference the navigation root is data.

Class naming

The root class is named AtlDataRootNode.

Module navigation object

The module navigation objects let you group test data methods by relevant modules. Module navigation objects can expose entity navigation objects.

Module names should be based on the names of the modules on the main menu. However, a short version or an abbreviation should be used to support brevity of test code.

Examples

  • Sales and marketing module: data.sales()
  • Inventory management module: data.invent()

Class naming

AtlData<ModuleName>

Examples

  • Sales and marketing module: AtlDataSales
  • Procurement and sourcing module: AtlDataPurch
  • Inventory management module: AtlDataInvent
  • Accounts receivable module: AtlDataCust
  • Accounts payable module: AtlDataVend

Entity navigation objects

Entity navigation objects let you group test data methods by relevant entities.

The plural of the entity name should be used as the name of the entity navigation node.

Examples

data.products().items();

data.whs().warehouses();

Class naming

AtlData<ModuleName><EntityNamePlural>

Examples

AtlDataProductsItems

AtlDataInventChargeGroups

Notes

The same entity navigation object can be exposed from multiple modules when this approach makes sense. For example, AtlDataProductsItems is exposed from both data.product() and data.invent().

Helper navigation objects

Sometimes, a test data method isn't specific to any entity. In this case, a helpers node can be exposed at the module level.

The helpers navigation node should be named helpers.

Examples

data.helpers();

data.whs().helpers();

Class naming

AtlData<ModuleName>Helpers

Examples

AtlDataHelpers

AtlDataWHSHelpers
