## Background
FIELD OF THE INVENTION
The present invention relates to the management of computer-based applications in general, and more particularly to automated testing of computer-based applications.
BACKGROUND OF THE INVENTION
Computer-based applications typically require that in order for the application to perform a particular action, a required state must exist, usually as the result of the application performing (e.g., being caused by a user or another application to perform) one or more actions prior to performing the particular action. For example, an application may require that certain variables be initialized before they may be operated upon. While such applications typically enforce an action sequence leading up to each required state, in some circumstances, such as during automated testing of an application, it is desirable to be able to instruct an application to perform an action without regard to the action's required state.

Reference is now made to FIG. 1, which is a simplified illustration of a system for detecting and inducing application states, constructed and operative in accordance with an embodiment of the present invention. In one embodiment the system of FIG. 1 is used in conjunction with an automated application testing system, such as the AppScan® system, commercially available from International Business Machines Corporation, Armonk, N.Y., that performs automated testing of World Wide Web-based applications. In the system of FIG. 1, a target action manager 100 receives or otherwise detects a request to perform a target action within a computer-based application 102. Prior to application 102 performing the target action, a state detector 104 determines if the requested target action requires that a predefined state first exist for application 102 before the target action may be performed. In one embodiment a description of the required predefined state is stored in a table 106 of action state descriptions that state detector 104 consults. State detector 104 compares the current state, such as may be retrieved from application 102, with the predefined state required by the target action to determine if they match, such as in accordance with predefined match criteria 108. If the current state does not match the predefined state, a state inducer 110 preferably induces the required state, such as by causing application 102 to perform a set of actions. In one embodiment the set of actions whose performance are required to induce the state are stored in a set 112 of action sets, with each action set in set 112 preferably being associated with a target action and known to induce the state required by the target action. An action set may also include a sequence in which the actions are to be performed. Once the required state has been induced, target action manager 100 causes or otherwise allows the target action to be performed by application 102.
The system of FIG. 1 may be understood by way of example, such as where a requested target action is performing a shopping cart checkout at a checkout web page of an e-commerce application. A predefined state that is required before the checkout is performed is defined in action state description table 106 as a user being logged in to the e-commerce application, and at least one item being present in the shopping cart, and match criteria 108 require that both be true. The current state as determined by state detector 104, however, indicates that no user is currently logged in to the e-commerce application, and no item is present in the shopping cart. State inducer 110 then accesses action set table 112 to identify the action set that is associated with the target action being requested. The action set includes logging a user into a login web page and placing one or more items into a shopping cart on an item selection web page. State inducer 112 then causes application 102 to perform the actions in the action set, whereupon target action manager 100 causes or otherwise allows the target action to be performed by application 102.
In one embodiment a manual identification is performed of each target action within application 102, its predefined state that must first exist for application 102 before the target action may be performed, and the actions or action sequence required to effect the predefined state. In an alternative embodiment the system of FIG. 1 includes an action set generator 114 that automatically generates action sets. An exemplary method for automatically generating action sets is described hereinbelow with reference to FIG. 3.
In one embodiment the system of FIG. 1 includes an action set optimizer 116 that optimizes any of the action sets in action set table 112. An exemplary method for optimizing action sets is described hereinbelow with reference to FIG. 4.
In one embodiment any of the elements shown in FIG. 1 are executed by or otherwise accessible to a computer 118, such as by implementing any of the elements shown in FIG. 1 in computer hardware and/or in computer software embodied in a computer-readable medium in accordance with conventional techniques.
Reference is now made to FIG. 2 which is a simplified conceptual illustration of an exemplary method of operation of the system of FIG. 1, operative in accordance with an embodiment of the invention. In the method of FIG. 2, a request to perform a target action within a computer-based application is received or otherwise detected. Prior to the application performing the target action, if the requested target action requires that a predefined state first exist for the application, the current state of the application is compared with the predefined state. If the current state does not match the predefined state, the application is caused to perform a set of actions that are associated with the target action and known to induce the state required by the target action. Once the required state has been induced, the application is caused or otherwise allowed to perform the target action.
Reference is now made to FIG. 3 which is a simplified conceptual illustration of a method for automatically generating action sets, operative in accordance with an embodiment of the invention. In the method of FIG. 3, action sets are automatically generated by generating non-looping graphs of possible action paths from a root application point, such as a start-up procedure that an application invokes when the application is executed, to one or more potential target action points within the application. When a request is made to perform a target action, if the current state of the application does not match a predefined state as described above, or if no predefined state exists for the target action, a path from the root application point to the target action is selected, preferably being the path between the two points having the fewest actions. The set of actions that lie along the selected path up to the target action are then performed prior to performing the target action as described hereinabove.
Reference is now made to FIGS. 4A and 4B which are simplified conceptual illustrations of methods for optimizing action sets, operative in accordance with an embodiment of the invention. In the method of FIG. 4A, a given action set for a given target action may be optimized by performing different candidate subsets of zero or more members of the action set. For example, if a sequence is defined for the action set, the action immediately preceding the target action may be performed to form one candidate subset, the two actions preceding the target action may be performed to form another candidate subset, and so on. The candidate subset with the fewest actions that produces a result that matches the result of the entire action set according to predefined match criteria, or that results in a state that matches a predefined state associated with the target action according to predefined match criteria, may then be selected. When a request is subsequently detected to perform the target action, only the actions in the selected subset need be performed prior to performing the target action.
Alternatively, as shown in the method of FIG. 4B, the target action itself may be performed and its result compared with either a known valid result for the target action or with the result of performing the entire action set followed by the target action. If the results match according to predefined match criteria, when a request is subsequently detected to perform the target action, only the target action need be performed. If the results do not match according to predefined match criteria, different candidate subsets of zero or more members of the action set may be performed as described above, followed by the target action. The candidate subset with the fewest actions followed by the target action that produces a result that matches a known valid result for the target action or the result of the entire action set followed by the target action according to predefined match criteria may then be selected. When a request is subsequently detected to perform the target action, only the actions in the selected subset need be performed prior to performing the target action.
Reference is now made to FIG. 5 which is a simplified conceptual illustration of a method for testing application flow enforcement, operative in accordance with an embodiment of the invention. A prerequisite action set may be defined (with or without a sequence) for a target action in an application requiring that the target action only be performed if it is preceded by the performance of the prerequisite action set. The present invention may be used to test whether such an application is indeed enforcing the prerequisite actions requirement, or whether the target action may be performed in the correct state even when the target action is not preceded by the performance of the prerequisite actions. In the method of FIG. 5, given a target action and a prerequisite action set for the target action, and given either a predefined required state for the target action or performing the prerequisite action set to determine the required state that exists prior to performing the target action, one or more candidate subsets are formed of zero or more actions of any action path leading up to the target action. If at least one such candidate subset can be formed that differs from the prerequisite action set, and/or if performing the actions of such a candidate subset produces the target action's required state, the application is said to not enforce the prerequisite action set.
The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
