Jemmy Operators Environment


Any Jemmy operator - subclass of org.netbeans.jemmy.operators.Operator class has its own environment which consists in Timeouts, Output, String Comparator, Component Visualizer, Verification Mode and Jemmy Properties. Operator environment is passed from one operator to another following next two rules:

  • Any operator created by constructor not having another operator as a parameter has default environment values which are taken from current Jemmy properties. Examples:
             new JFrameOperator("My Frame");
             new JDialogOperator("My Modal Dialog");
             new JPopupOperator();
             new JFileChooserOperator();

  • Any operator created by constructor having another operator as a parameter copies all environment from that operator by Operator.copyEnvironment(Operator) method. Example:
             new JFrameOperator("My Frame", 0, anotherFrameOperator);
             new JButtonOperator(frameOperator, "Help");


All Jemmy timeout values are kept by org.netbeans.jemmy.Timeouts class. Any class instance might hold any number of timeouts definition. Each timeouts defines by string name typically looking like ClassName.TimeoutName<code>. Example: AbstractButtonOperator.PushButtonTimeout, WindowWaiter.WaitWindowTimeout

Default Timeouts value is taken by operators constructors by <code>org.netbeans.jemmy.JemmyProperties.getCurrentTimeouts() method. Timeouts have values from the table below unless timeout values are specified in a file defined by "" environment variable.

Besides current timeout value kept by each Timeouts instance, each timeout also has a default value. If any particular Timeouts instance does not have some timeout defined, its default value is returned. Example:

Timeouts timeouts = JemmyProperties.getCurrentTimeouts();
//-1 in output
Timeouts.setDefault("Definitely.Nonexistent.Timeout", 222);
timeouts.setTimeout("Definitely.Nonexistent.Timeout", 333);

Any operator has a set of timeouts which are necessary to get it working. These timeouts default values are declared in correspondent class' static initializer section like this: Example (from AbstractButtonOperator):

    static {
	Timeouts.initDefault("AbstractButtonOperator.PushButtonTimeout", PUSH_BUTTON_TIMEOUT);

Default values for all existing timeouts are in this table:

Any class implementing org.netbeans.jemmy.Timeoutable can have its own timeout values. If a component operator created for has subcomponents, the operator tipically creates suboperators for those components itself. I might also create a copy of Timeouts by Timeouts.cloneThis() method and change some timeout values for a suboperator.

Example (from JScrollBarOperator):

	minButtOperator = new JButtonOperator(minButt);
	Timeouts times = timeouts.cloneThis();

Noone from existing operators changes a contents of Timeouts instance passed into setTimeouts(Timeouts) methods, so it's safe to pass existing Timeouts into any operator (which is done by all the operators constructors).


Output streams are held by org.netbeans.jemmy.TestOut class instance. Like Timeouts there exists an interface for a classes having own output settings: org.netbeans.jemmy.Outputable

Default TestOut value is taken by operators constructors by org.netbeans.jemmy.JemmyProperties.getCurrentOutput() method. By default System.out and System.err are used as output streams. If*) method is used to execute tests, streams are defined by parameters passed into this method.

Like with timeouts some operators might create new TestOut instance different from what they have.

Example (from JScrollBarOperator):

	minButtOperator = new JButtonOperator(minButt);

String Comparator

Implementation of org.netbeans.jemmy.operators.Operator.StringComparator defines the way to compare component string properties such as text, items, cell text with a pattern. A comparator instance assigned to operator is used for any operators' methods having String parameter and not having another comparator as a parameter. The comparator instance is also used for subcomponent finding (if component is searched by string property) following rules described above. Comparator is simple passed from operator to suboperators with no change.

Comparator used by default is new org.netbeans.jemmy.operators.Operator.DefaultStringComparator(false, false)

Component Visualizer

Implementations of org.netbeans.jemmy.operators.Operator.ComponentVisualizer interface is used to prepare component for user input. Default implementation - org.netbeans.jemmy.util.DefaultVisualizer is able to activate window containing component, scroll panes under the components, switch pages of a tabbed pane, activate internal frame.

Some operators might create an org.netbeans.jemmy.util.EmptyVisualizer instance for suboperators to avoid unnecessary actions.

Verification Mode

Boolean verification property defines if operator should verify/wait for appearing of correct result of operation. For example, verify text typing operation by waiting for typed text to be displayed inside component.

Jemmy Properties

Each operator has a pointer to JemmyProperties. This pointer copied from one operator to another like other properties. JemmyProperties assigned to operator used to get driver set.
