## Title
Debugging a graphical user interface code script with non-intrusive overlays

## Abstract

An embodiment of the present invention manages window focus non-intrusive over-lays while debugging a graphical user interface program. In an example, the computer displays in a first graphical user interface, wherein the computer program is designed to manipulate a second graphical user interface of another computer program. The computer receives a command to debug the second graphical interface computer program and converts the first graphical user interface into a focus-less graphical user interface so the focus does not transfer from the second graphical user interface. The computer debugs the computer program and upon completing debugging, the computer restores the first graphical user interface into focus.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. patent application Ser. No. 13/717,794 filed on Dec. 18, 2012, the entire content and disclosure of which is incorporated herein by reference.


FIELD OF THE INVENTION
The present invention relates generally to the field of debugging software, and more particularly to window focus on graphical user interfaces.
BACKGROUND OF THE INVENTION
Most computing devices, applications and complex tools rely upon a user interface to interact with, receive input from and provide information to users. There are many types of user interfaces which can be implemented and they can include graphical user interfaces (GUI), character user interfaces (CUI) and web-based user interfaces. The development of such software containing user interfaces, more specifically GUIs, involve the proper testing and verification of the performance and functionality of the GUI being tested. The testing of the GUI typically requires user interaction to ensure the aspects of the GUI are properly covered. Depending on the complexity of the GUI, the number of manual operations by the user to test the GUI can easily be an order of large magnitude. An automated GUI testing program, referred to herein as a GUI automation program, could be used to automatically simulate these otherwise manual operations by the user. However, since a GUI automation program is software in itself, it also has to be tested to ensure proper functionality.
As a GUI automation program performs its own testing functions on a GUI, a debugger program may simultaneously test the GUI automation program to ensure that the GUI automation program is functioning properly. During this process, the GUI being tested is the focus of the display. The GUI automation program and the debugger program typically operate in an integrated development environment (IDE). During the process of debugging an application, the IDE may take over the window focus in order to display information to the user. Any input made on the IDE may disrupt the GUI automation program and any automated processes or input being made by the automation program (i.e., mouse movement) on the GUI under test.
SUMMARY
Embodiments of the present invention disclose a method, computer program product, and computer system for managing window focus while debugging a graphical user interface automation.
In an example, the computer displays in a first graphical user interface, wherein the first graphical user interface is designed to manipulate a second graphical user interface of another computer program. The computer receives a command to debug the second graphical interface computer program. The computer converts the first graphical user interface into a focus-less graphical user interface. The first graphical interface program computer debugs the computer program. Subsequent to completion of said debugging, the computer restores the first graphical user interface into focus.

The present invention will now be described in detail with reference to the Figures. FIG. 1 is a functional block diagram illustrating computer device 102 containing various programs, in accordance with one embodiment of the present invention.
Computer device 102 may be a laptop computer, tablet computer, netbook computer, personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, or any programmable electronic device capable of hosting a graphical user interface (GUI). Computer program under test (CPUT) 104 and Integrated Development Environment (IDE) 108 are located on computer device 102. IDE 108 hosts debugger program 112 and GUI automation program 114. IDE 108 allows for the use of one graphical user interface (i.e., GUI 110) for both debugger program 112 and GUI automation program 114, so that a user has one window capable of displaying output of each program instead of two separate windows.
IDE 108 is not limited to hosting debugger program 112 and GUI automation program 114. It will also be recognized that although debugger program 112 and GUI automation program 114 may be accessed via IDE 108 sharing a single GUI in one embodiment, in another embodiment, these programs may have their own GUIs rather than sharing a single GUI (i.e. GUI 110). Debugger program 112 evaluates the state and code script of CPUT 104 as well as the state and code script of GUI automation program 114 so it can intercept, modify, and represent troubleshooting aspects of tasks being performed as part of CPUT 104 and its GUI 106. CPUT 104 may be any program utilizing a GUI.
FIG. 2 is a flowchart, depicting operational steps of implementing a focus-less GUI display as part of an IDE while debugging an automated GUI testing program, in accordance with an embodiment of the present invention.
In an exemplary embodiment, CPUT 104 is being tested by manipulating GUI 106 via GUI automation program 114. During this process, debugger program 112 can detect and/or be used to correct any errors in (i.e., debug) the code of CPUT 104 and/or the code script of GUI automation program 114. GUI automation program 114 and debugger program 112 are hosted by IDE 108, allowing them to share a single graphical display window. GUI 106 retains the window focus of computer device 102 while GUI automation program 114 causes CPUT 104 to perform tasks automatically. As GUI automation program 114 performs scripted inputs on GUI 106, the state of CPUT 104 can be evaluated by debugger program 112 to ensure that certain defined behaviors (i.e. exception conditions, values out of range, etc.) either do not occur or coincide as expected with the inputs being performed.
Prior to the debugging process beginning, IDE 108 intercepts the initialization of the debugging process (step 202). Since debugger program 112 and GUI automation program 114 are part of IDE 108, IDE 108 has the ability to detect when a program (i.e., debugger program 112) is performing a task, thus intercepting the task. In this example, the task being performed is the initialization of the debugging process by debugger program 112. Once IDE 108 intercepts the initialization of the debugging process, IDE 108 initializes a focus-less display (step 204). The focus-less display (i.e., GUI 110) allows for the focus to remain on the GUI being tested by GUI automation program 114 (i.e., GUI 106). The focus-less display of GUI 110 is a semi-transparent display appearing in front of all other GUIs which may be present. Due to the semi-transparent display, the user will be able to see what is being presented by GUI 110 as well as GUI 106. The focus-less display of GUI 110 allows for debugger program 112 to convey information which may be, but is not limited to, the status of GUI automation program 114 and the correlating code script, specified breakpoints, highlighted program code errors, user controls, or a status report. The focus-less display of GUI 110 allows for information to be available to the user during the debugging process without having to switch between two or more GUIs (i.e., GUI 106 and GUI 110).
IDE 108 initializes the debugging process (step 206) which was previously intercepted in the discussion of step 202. As a result of the focus-less display of GUI 110, GUI 106 is evaluated properly by GUI automation program 114 since GUI 106 retains the window focus.
IDE 108 monitors the debugging process to determine if the debugging process has ended (step 208). Upon determining the debugging process has ended (yes branch, step 208), IDE 108 restores the display (i.e. GUI 110) into focus (step 210). IDE 108 will bring GUI 110 into focus since GUI 106 is no longer being tested by GUI automation program 114.
FIG. 3 is a flowchart depicting operational steps for implementing a user input filter as part of an IDE while debugging an automated GUI testing program in accordance with an embodiment of the present invention.
In an exemplary embodiment, focus-less display of GUI 110 as previously mentioned in the discussion of FIG. 2, operates in parallel with the process of filtering user inputs. Prior to the debugging process beginning, IDE 108 intercepts the initialization of the debugging process (step 202). Once IDE 108 intercepts the initialization of the debugging process, IDE 108 initializes user input filter (step 302). In this example, the user input filter is a feature of IDE 108 which allows for IDE 108 to receive input from the user while the debugging process of the GUI automation program 114 is occurring. The user input filter will coincide with the focus-less display of GUI 110 so it does not interfere with GUI automation program 114 properly testing GUI 106. GUI automation program 114 can use the same set of user input controls (i.e., mouse and keyboard) to evaluate GUI 106 as a user may need to access information on the focus-less display of IDE 108. The user can specify when the user inputs are to be entered on the focus-less GUI 110 rather than GUI 106. The user can “step-into” or “step-over” the code script of GUI automation program 114 by entering a specified set of commands which are not normally used by GUI automation program 114 to evaluate GUI 106. Stepping-into the code script of GUI automation program 114 allows for the user to alter the code script and make appropriate changes according to information provided by debugger program 112. Stepping-over the code script of GUI automation program 114 allows for the user to enter in new code-script prior to it being used to test CPUT 104. Such specified sets of commands allowing for the user to step-into or step-over the code script of GUI automation program 114, may be located in a directory of IDE 108. The directory can have the specified sets of commands pre-programmed or the user can select their own preferences for which commands correspond to each user input.
IDE 108 initializes the debugging process (step 206) which was previously intercepted in the discussion of step 202 upon which then IDE 108 monitors the debugging process to determine if the debugging process has ended (step 208). Upon determining the debugging process has ended (yes branch, step 208), IDE 108 removes the user input filter (step 304). Any input entered by the user in IDE 108 will automatically be part of the window focus and no longer filtered by IDE 108.
The use of non-intrusive overlays (i.e., focus-less display and user input filter) allows for proper debugging of the code script of GUI automation program 114 while it tests GUI 106 belonging to CPUT 104.
FIG. 4 is a flowchart depicting operational steps for filtering a user input by IDE 108, in accordance with an embodiment of the present invention. When a debugging process is initialized as previously discussed in step 206, user input filter would have been initialized on the focus-less display of GUI 110.
IDE 108 receives a user input (step 402). The user input received by IDE 108 may be through any device that can communicate with the computer device 102. Such a device may contain but is not limited to: a keyboard, a mouse or a separate computing device. Upon receiving the input, IDE 108 checks the user input according to a directory (step 404). The directory is a specified list of commands which allow for the user inputs to be filtered through to IDE 108. In an example, the directory can be a list of a predetermined set of combination of keys pressed on a keyboard which will allow for the user to be able to provide input into IDE 108 without drawing the window focus away from GUI 106. As previously mentioned in the discussion of FIG. 3, the list may contain but is not limited to a combination of keys for stepping into or stepping over the code script of GUI automation program 114. The combination of keys would not be used in the testing of CPUT 104 by GUI automation program 114. This is to ensure the command representing the specific combination of keys pressed will not interfere in the testing being performed by GUI automation program 114.
IDE 108 determines if the user input can pass through the filter (step 406). Upon IDE 108 determining the input entered by the user is not on the directory (no branch, step 406), IDE 108 will not display those inputs on the focus-less display of GUI 110. Upon IDE 108 determining the input entered by the user is on the directory (yes branch, step 406), IDE 108 displays user input on the focus-less display of GUI 110 (step 408).
FIG. 5 depicts a block diagram of components of computer device 102 in accordance with an illustrative embodiment of the present invention. It should be appreciated that FIG. 5 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environment may be made.
Computer device 102 includes communications fabric 502, which provides communications between computer processor(s) 504, memory 506, persistent storage 508, communications unit 510, and input/output (I/O) interface(s) 512. Communications fabric 502 can be implemented with any architecture designed for passing data and/or control information between processors (such as microprocessors, communications and network processors, etc.), system memory, peripheral devices, and any other hardware components within a system. For example, communications fabric 502 can be implemented with one or more buses.
Memory 506 and persistent storage 508 are computer-readable storage media. In this embodiment, memory 506 includes random access memory (RAM) 514 and cache memory 516. In general, memory 506 can include any suitable volatile or non-volatile computer-readable storage media.
CPUT 104, debugger program 112, and GUI automation program 114 are stored in persistent storage 508 for execution by one or more of the respective computer processors 504 via one or more memories of memory 506. In this embodiment, persistent storage 508 includes a magnetic hard disk drive. Alternatively, or in addition to a magnetic hard disk drive, persistent storage 508 can include a solid state hard drive, a semiconductor storage device, read-only memory (ROM), erasable programmable read-only memory (EPROM), flash memory, or any other computer-readable storage media that is capable of storing program instructions or digital information.
The media used by persistent storage 508 may also be removable. For example, a removable hard drive may be used for persistent storage 508. Other examples include optical and magnetic disks, thumb drives, and smart cards that are inserted into a drive for transfer onto another computer-readable storage medium that is also part of persistent storage 508.
In these examples, communications unit 510 includes one or more network interface cards. Communications unit 510 may provide communications through the use of either or both physical and wireless communications links. CPUT 104, debugger program 112 and GUI automation program 114 may be downloaded to persistent storage 508 through communications unit 510.
I/O interface(s) 512 allows for input and output of data with other devices that may be connected to computer device 102. For example, I/O interface 512 may provide a connection to external devices 518 such as a keyboard, keypad, a touch screen, and/or some other suitable input device. External devices 518 can also include portable computer-readable storage media such as, for example, thumb drives, portable optical or magnetic disks, and memory cards. Software and data used to practice embodiments of the present invention, e.g., CPUT 104, debugger program 112 and GUI automation program 114 can be stored on such portable computer-readable storage media and can be loaded onto persistent storage 508 via I/O interface(s) 512. I/O interface(s) 512 also connect to a display 520.
Display 520 provides a mechanism to display data to a user and may be, for example, a computer monitor.
