Create Object

Definition​

With this Teststep type, an object is created in-memory.

To save it to the database, add a Persist step.

Depending on the Apply security setting on the Test Case, the object is created only if the Execution User is allowed to based on the domain model access rules in the Mendix model.

Domain model event handlers (Before Create and After Create), if configured, are triggered.

Entity Access​

Security applied​

If the Test Case that this teststep is in, has Apply Security enabled, the Create rights on the Entity, through the configured Entity rights will be evaluated by the MTA Plugin to check if the Execution User may create a new object. If there are no Create rights, an error will be shown on the Test Run, and the Test Run will stop.

Security not applied​

If the Test Case that this teststep is in, does not have Apply Security enabled, a new object may always be created.

Add a Create Object Teststep​

  • Navigate to the Test Suite and move the mouse to the position you want to create a Teststep in.
  • Click and Click Teststep: Create object to add a Create Teststep.
  • Select an entity. You can search by name.

Set values​

info

Binary attributes are not supported by MTA.

Set Fixed value​

  • Click Add attributes to add them, or Edit values to change values for existing attributes.
  • Select one or more attributes.
  • Enter or select value(s).

For datetime values you can either specify a date, or calculate the date with an offset from the current datetime.

Note that not including an Attribute Value in a Create Object Teststep will make the value default to what has been configured in the Mendix domain model (usually empty). Including an Attribute but not entering a value will make the value empty for all datatypes except the String datatype. A String attribute will be given the zero-length value ('').

Use a former Teststep to set an Attribute Value​

  • Click Edit values and select Teststep.
  • Select the Teststep and (if the Teststep returns an Object) find the Attribute that should provide the value.

Assign associations​

  • Click Add associations.
  • Select one or more associations.
  • Select an operator: either Set (the default), or Add / Remove (both only available for many-to-many associations).
  • Using Edit, Select a previous Teststep, or add a Create/Retrieve Teststep that provides one associated object. You can also set the association to EMPTY.
  • For many-to-many associations, you can add additional lines.

Add a Create object Teststep by App Instance​

You can choose to fill all the attributes and associations using existing values in the database.

  • Navigate to the Test Suite and move the mouse to the position you want to create a Teststep in.
  • Click and Click Teststep: Create object by app instance to add a Create Teststep.
  • Select an entity. You can search by name.
  • Select an object. You can filter by attribute value, by clicking Find objects by attribute filters.
note

Because of performance reasons, the amount of associations retrieved is limited to 3.
