Studio:AutoScript

 

Introduction 

Ascript is the definitive hierarchy of methods, objects, and properties provided by Autosense. While Autosense helps the user find the script methods/data desired in a script, Ascript is the definitive source of what is available from STRIDE when using Autosense.

The ascript object provides functionality that allows host-based scripts to interact with target-based binaries through the STRIDE Runtime. Through ascript, you can:

• call target-based functions and messages (synchronously or asynchronously)
• set and read parameter values orf these functions and messages
• transparently emulate (mock) target-based functions

Automation API

Ascript

When creating a script, the user types in Ascript followed by dot '.' to get Autosense to display. The user may select methods to be used within his script. The user may access property data within his script. this API is the definitive API for Autosense. The following table outlines the main objects and collections available to the user.

Member	Type	Description
Arguments	Collection	Collection of arguments.
Constants	Collection	Collection of constants.
Database	Object	Database settings.
Functions	Collection	Collection of functions.
void Initialize (    String STIDName,    String databaseFile,    Integer messageBoxTimeout [optional] )	Method	Initializes and ascript object instance that has been created outside of tghe STRIDE Studio environment. This call is needed only on an explicitly-created ascript instance. This call should not be made on an ascript instance automatically created and injected into a script by STRIDE Studio.
IsEventPending	Property, Read-only, bool	Contains true if there is at least one event in this script's message queue. Events are retrieved from the queue using ascript.WaitForEvent();
LogicalPath	Property, Read-only, String	Contains the script's path in the STRIDE Studio workspace tree.
void MessageBox(     String message,    String title [optional],     String type )	Method	Displays a model message box dialog.

Output	Property, (String, integer, or object)	This is the return value from a RunBlocking() call that invoked this script. This works only when the script is invoked using RunBlocking() in the studio object model.
RspTimeoutPeriod	Property, Integer	This is the timeout threshold for synchronous function and message calls (in milliseconds). A zero value indicates no timeout.
ScriptName	Property, Read-only, String	Contains the name of the currently running script with extension and without path. If the current ascript instance was instantiated and initialized outside of STRIDE Studio, this value will reflect the STIDName passed to ascript.Initialize().

WaitTimeoutPeriod	Property, String	The timeout threshold (in milliseconds) for asynchronous function and message calls. A zero value indicates no timeout.

Ascript.Arguments

The Arguments collection represents the arguments passed to a script which has been invoked via one of the following methods of the Studio Object Model's File object:

• RunBlocking([arg1], [arg2], ...)
• RunNonBlocking([arg1], [arg2], ...)

The default sort order of the member argument objects is the order in which the arguments were given in the call where the script was invoked.

Member	Type	Description
Count	Property, Read-only, Integer	Returns the number of Arguments in this collection.
object Item (     Integer index )	Method	Retrieves the argument at the given index. An exception is thrown if the index is out of range.
object Item (     String name )	Method	Retrieves the argument with the given name. If a named argument doesn't exist, null is returned.

Ascript.Arguments.Item

An individual argument is accessed from the collection using the item(#) interface.

Member	Type	Description
Name	Property, Read-only, String	The argument name. The name may have been specified in the studio automation RunBlocking() or RunNonBlocking() call that launched the script or if not specified the name is synthesized by the ascript object. When synthesized, the name is of the form "Unnamed_N" where 'N' is a monotonically incremented number starting from 0.
Value	Property, Read-only, String, Integer, or Object	The argument value.

Ascript.Constants

Constants is a collection of constants contained and managed through Ascript.

The 'By' parameter may only be "Name". If not specified, the default is "Name". This represents how Constants should be sorted in the collection. The 'Order' parameter may be either "Ascending" or "Descending". If not specified, the default is "Ascending". Exception thrown if either argument is outside legal values.
Count	Property, Read-only, Integer	Returns the number of Constants in this collection.
object Item (     Integer index )	Method	Retrieves the constant at the given index. An exception is thrown if the index is out of range.

Ascript.TestUnits.Item

The Test Unit object represents a captured Test Unit interface in the currently active STRIDE database. A Test Unit object always exists as a member of the TestUnits collection and is accessed from the collection using the item(#) interface.

Member	Type	Description
Arguments	Object	Test Unit parameter list payload.
Name	Property, Read-only, String	Test Unit name.
IsRegistered	Property, Read-only, bool	Contains true if the Test Unit owner has registered on the target side.
void Run (void)	Method	Method to run the test unit.
Suite	Property, object	An object of type Reporter's TestSuite. By default after a run this object is a sub-Suite of ascript.TestSuite with the same name as the Test Unit (null if no reporting performed). Setting Suite to a concrete external TestSuite prior to execution will override default creation behavior (set to null to revert to default behavior).
Summary	Property, integer	Contains static payload object of type srTestCaseTotals_t with result (i.e. pass, fail, in progress, not in use).
Type	Property, Read-only, String	Contains test unit type (i.e. TestClass, TestCClass, or TestFList).

Ascript.Timers

The Timers collection manages a set of Timers. The Timers allow scripts to generate periodic or 'one-shot' timed events.

Upon creation, the Timers collection is empty.

The Timers collection is the only read/write collection in STRIDE; member Timer objects can be added (implicitly created) and removed by scripts.

From the collection's point of view, member Timers have two states: dead and alive. Timers are alive upon creation and remain so as long as they exist in the collection. A Timer object that is removed from the collection is considered dead. Any operation on a dead timer will cause an exception to be thrown.

A time object that is removed from the collection is automatically stopped before removal if it is active. No event is generated in this case.

The collection remains unsorted (Timer objects are held in the order in which they were added) unless ArrangeBy() is called.

Member	Type	Description
object Add (     object timerObject )	Method	Adds a new timer object.
void ArrangeBy (    String By [optional],    String Order [optional] )	Method	Sorts the Timers collection so that indexing by position yields predictable results. The 'By' parameter may only be "Name". If not specified, the default is "Name". This represents how Timers should be sorted in the collection. The 'Order' parameter may be either "Ascending" or "Descending". If not specified, the default is "Ascending". Exception thrown if either argument is outside legal values.
Count	Property, Read-only, Integer	Returns the number of Timers in this collection.
object Item (     integer index )	Method	Retrieves the Timer object for the given index.
object Remove (     integer index )	Method	Removes the timer at the given index.

Ascript.Timers.Item

The Timer object enables scripting clients to synthesize and receive timer-based periodic or one-shot events.

When a timer expires and rires its event, the event is queued and can be accessed by the ascript.WaitForEvent() method. The expired timer object will be returned by WaitForEvent();

Member	Type	Description
Active	Property, Read-only, bool	Contains timer operation state. True if timer is in operation (i.e. it will generate an event at some time in the future). A newly created timer is inactive by default.
Id	Property, Read-only, long	Contains timer identifier.
Duration	Property, long	Timer duration in milliseconds.
Name	Property, Read-only, String	Name assigned when the timer was created. Default names are "Timer_n" where 'n' is the nth named time created by this ascript object.
Periodic	Property, bool	When false, the time will fire only once (one-shot mode). When true, the time automatically restarts after each event is fired. This property can be changed regardless of the state of the timer. This field is false by default when a timer is created.
void Start (void)	Method	Transitions an inactive timer to active. Once started, the timer will run for the length of time specified by its Duration property. Calling Start on a timer with a zero/negative duration will cause an exception to be thrown. Calling Start on a timer that has already started will also cause an exception to be thrown.
void Stop (void)	Method	Transitions an active timer to inactive. Calling Stop on a timer that is not active will cause an exception to be thrown.
Type	Property, Read-only, String	Contains the string "Timer". This property is typically used to classify an object that is returned from ascript.WaitForEvent().
