Editor layer extension points

The editor layer enables you to write protocol extensions. During the initialization process, a number of extension points are checked for extensions that define different aspects of the test editor.

The editor layer extends classes from the common framework layer to provide specific implementations for their models. The extensions must be defined in the protocol-specific plug-ins extending the test editor.

Extension point Description
dataCorrelationHandler

  • Defines an entry in the Data Correlation Handler Selection window. The handlers are queried and displayed in a dialog for the user to choose when there is more than one protocol capable of creating data correlation objects out of the selected text.

  • The user interface descriptor of a handler is matched to its data correlation package through the typeID attribute in the extension point.
  • dataCorrelationUICategory Defines a category for grouping built-in data sources that are represented in the user interface by the dataCorrelationUIDescriptor extension point.
    dataCorrelatorUIDescriptor Provides visual representation for built-in data source types. These are grouped under data correlation user interface categories in the Built-in Datasource Selection Wizard. The wizard is displayed when the user wants to create data correlation with a built-in data source.
    wizardPageContributor Used for contributing a protocol specific page or pages to the New RPT Test Wizard.

    The protocol handler can make a contribution to the details page of the test to protocol-specific test-wide options. If protocol needs to support data correlation, you can use the class DataCorrelationLabelProvider. The class contains several methods to use with data correlation. Many of the methods deal with display aspects of the data correlation objects.

    In data correlation there must be an attribute name assigned to each field or property of a model object that supports data correlation. These names are used for many purposes, one of which is to provide formatted labels for data correlation objects. Because the LoadTest editor creates labels early in a process cycle, these labels may not contain detailed formatting instructions.

    To overcome this issue, higher level protocol extensions or plug-ins can register LabelFormatters called when needed.
