Test data methods

  • Článek

Entity and helper navigation objects expose test methods that let you set up test data. This article provides information about the most common types of test data methods.

Factory methods

Factory methods focus on creating data that doesn't yet exist in the database. There are two types of entity factory methods, init methods and create methods. An init method initializes the entity but doesn't save it to the database. A create method initializes the entity and saves it to the database.

Naming convention

init<EntitySpecification>

create<EntitySpecification>

In this naming convention, <EntitySpecification> is the description of the key characteristics of the object that must be created.

Examples

salesOrder = data.sales().salesOrders().initDefault();

purchaseOrder = data.purch().purchaseOrders().createDefault();

Best practices

The create method should always call the init method that has the same entity specification.

Example

public AtlEntitySalesOrder createDefault()
{
    AtlEntitySalesOrder salesOrder = this.initDefault();
    salesOrder.save();
    return salesOrder;
}

Prerequisite data

The init method should take care of setting up prerequisites.

Before some entities can be created, specific prerequisites must be set up. In these cases, the ensure method must be called before the entity is initialized. You must also subscribe to all the entity events that require automatic setup of prerequisites.

Example

public AtlEntitySalesOrder initDefault()
{
    AtlEntitySalesOrder salesOrder;

    this.ensureCanCreate();

    salesOrder = new AtlEntitySalesOrder();
    salesOrder.parmCustomer(data.cust().customers().default());

    _salesOrder.postingInvoice += eventhandler(this.ensureCanPostInvoice);
    _salesOrder.postingPackingSlip += eventhandler(this.ensureCanPostPackingSlip);
    _salesOrder.releasingToWarehouse += eventhandler(this.ensureCanReleaseToWarehouse);
}

Builder methods

Builder methods are responsible for initializing creator objects that will be used to create data that doesn't yet exist in the database.

Naming convention

<EntitySpecification>Builder

In this naming convention, <EntitySpecification> is the description of the key characteristics of the object that must be created.

Example

catchWeightItem = data.invent().items().cwBuilder();

Well-known data methods

Well-known data methods provide a way to reference an entity that is set up in a specific way. If the entity doesn't exist in the database, it's created.

Naming convention

<EntitySpecification>

In this naming convention, <EntitySpecification> is the description of the key characteristics of the object that must be retrieved.

Example

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

In this example, the contract of the method specifies that the model group should use first in, first out (FIFO) as the inventory model. The rest of the settings can be left at their default values.

Sometimes, a real-world name communicates the contract better.

pieces = data.common().units().pieces();

In this example, it's clear that pieces is a unit of measure of the "quantity" class, and that is has a decimal precision of 0 (zero).

Contract of well-known data methods

Here are a few things to remember about the common contract of the well-known data methods.

  • Two calls to the same well-known data method should provide the caller with the reference to the same entity.

    fifo1 = data.invent().modelGroups().fifo();
fifo2 = data.invent().modelGroups().fifo();
fifo1.InventModelGroupId == fifo2.InventModelGroupId;

  • Creation of a test entity isn't always worth the effort. If a test entity isn't created, the corresponding record buffer should be returned from the well-known data method. For example, if you don't invest the time and effort to create the Site entity, the site well-known data method will return InventSite records.

    InventSite site = data.invent().sites().default();

  • Well-known data methods can take IDs as optional parameters when this approach makes sense.

    item1 = data.products().items().default('Item1');
item2 = data.products().items().default('item2');

Implementation

If there is already a builder or a factory method that is named <EntitySpecification>, it should be used as the internal implementation to create the well-known entity.

Example

public InventTable whsBatchAbove(ItemId _itemId = this.whsBatchAboveItemId())
{
    InventTable whsItem = InventTable::find(_itemId, true);
    if (!whsItem)
    {
        whsItem = this.whsBatchAboveBuilder().setItemId(_itemId).create();
    }
    return whsItem;
}

Ensure methods

Ensure methods are responsible for setting up prerequisites that are required in order to create an entity or run a business operation.

Naming convention

ensureCan<ExecuteBusinessOperation>

In this naming convention, <ExecuteBusinessOperation> is a verb that describes the business operation.

Examples

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

data.purch().purchaseOrders().ensureCanPostProductReceipt();

Implementation

Figuring out prerequisites for a complex business operation, such as invoice posting, can be complicated and requires lots of knowledge about the feature area.

Example

public void ensureCanCreate()
{
    data.helpers().setNumberSequenceReference(extendedTypeNum(InventDimId));
}

Automatic prerequisite setup

To enable automatic prerequisite setup, you must call the ensure methods in the appropriate init method. For more information, see the Factory methods section earlier in this article.

Query methods

Query methods are responsible for initializing new queries for the entity type of the navigation node that they are defined on.

Naming convention

query

Examples

loadLinesQuery = data.whs().loadLines().query();

purchaseLinesQuery = data.invent().transferOrderLines().query();

Specification methods

Specification methods are responsible for initializing new specification objects for the entity type of the navigation node that they are defined on.

Naming convention

spec

Example

loadLinesSpec = data.whs().loadLines().spec();

Find methods

Find methods let you find an entity based on the primary key.

Naming convention

find

Example

salesOrder = data.sales().salesOrders().find(salesOrderId);

Automatic prerequisite setup

If the entity has query support, the implementation should use the query that has already set up prerequisite support. Otherwise, after you find the record buffer and initialize the new instance of the entity, you should subscribe ensure methods to the business operation events of the entity.
