Abstract

Disclosed are methods, systems, and articles of manufacture for synchronizing a software verification flow of an application that uses a user interface. Various embodiments comprise implementing a menu item as a widget and identifying an operation associated with the menu item. A synchronizer is further identified or created for the operation and then registered with the operation such that the synchronizer is activated when the operation is invoked during the software verification flow. Once activated, the synchronizer takes over control of the verification flow and prevents the verification flow from proceeding until a criterion is fulfilled. The synchronizer may be reused among different tests, and the same test case may be rerun on different machines with different computing performance and workloads without producing false positives or false negatives.

Claims

1. A computer implemented method for synchronizing a software verification flow, the method comprising:

using a computer system which comprises at least one processor to perform a process, the process comprising;

identifying a component operation associated with a menu item of a user interface, wherein the component operation includes an element to be tested in the software verification flow and represents an act of triggering the menu item in the user interface;

identifying or creating a synchronizer;

registering the synchronizer with the component operation;

synchronizing the software verification flow by using the synchronizer, without including wait statements in the software verification flow to instruct the software verification flow to pause execution and to wait for a particular state to proceed with verification.

2. The computer implemented method of claim 1, wherein

the act of synchronizing comprises determining whether a criterion has been fulfilled, and

the criterion comprises an occurrence of a state that indicates completion of the component operation.

3. The computer implemented method of claim 2, wherein the act of synchronizing comprises taking control of the software verification flow by using the synchronizer until the criterion has been fulfilled.

4. The computer implemented method of claim 2, wherein

the act of synchronizing prevents the software verification flow to proceed to a next stage until the criterion is fulfilled;

and

the act of synchronizing is performed without placing a synchronization requirement into a test case of the software verification flow.

5. The computer implemented method of claim 1, wherein the act of synchronizing is performed automatically without human manipulation of the software verification flow.

6. The computer implemented method of claim 2, wherein

the act of synchronizing causes the software verification flow to wait for an amount of time, and

the amount of time is no more or no less than what is necessary to conserve computing resources.

7. The computer implemented method of claim 1, wherein the act of identifying or creating the synchronizer comprises:

defining a synchronizer struct for the synchronizer from a base struct, in which the act of defining the synchronizer struct comprises defining one or more commands to which the synchronizer listens.

8. The computer implemented method of claim 7, wherein the act of defining the one or more commands comprises:

defining a wait logic for the synchronizer struct.

9. The computer implemented method of claim 8, wherein the act of identifying or creating the synchronizer comprises:

registering the synchronizer as listener to the menu item.

10. The computer implemented method of claim 7, further comprising:

defining a method for instantiating an instance of the synchronizer struct; and

passing the instance as a parameter to an application programming interface for the act of registering the synchronizer with the component operation.

11. The computer implemented method of claim 1, further comprising:

causing the synchronizer to be activated, wherein

the synchronizer is stored in a central repository to be reused for one or more other software verification flows, and

the synchronizer is activated when the component operation is invoked in the software verification flow.

12. The computer implemented method of claim 1, wherein the act of registering the synchronizer with the component operation occurs only once for a first occurrence of the component operation but not for subsequent occurrences of the component operation in the software verification flow.

13. The computer implemented method of claim 11, wherein the act of causing the synchronizer to be activated further comprises:

causing a synchronizer pre-event to be activated before invoking the component operation in the software verification flow, or

causing a synchronizer post-event to be activated after invoking the component operation in the software verification flow.

14. The computer implemented method of claim 1, further comprising:

implementing the menu item as a widget for the user interface.

15. The computer implemented method of claim 14, wherein the act of implementing the menu item as a widget comprises:

creating or modifying a menu item struct;

identifying or determining a method for activating the menu item within the menu item struct;

determining a second method for registering one or more operations for the menu item struct; and

implementing one or more plug-ins.

16. The computer implemented method of claim 15, further comprising:

calling one or more synchronizer pre-event operations before implementing the one or more plug-ins; and

calling one or more synchronizer post-event operations after implementing the one or more plug-ins.

17. The computer implemented method of claim 15, wherein the one or more plug-ins invoke the method for activating the menu item in the software verification flow.

18. A machine for synchronizing a software verification flow, the machine comprising:

a computer system which comprises at least one processor that is at least to;

identify a component operation associated with a menu item of a user interface, wherein the component operation includes an element to be tested in the software verification flow and represents an act of triggering the menu item in the user interface;

identify or creating a synchronizer;

register the synchronizer with the component operation; and

synchronize the software verification flow by using the synchronizer, without including wait statements in the software verification flow to instruct the software verification flow to pause execution and to wait for a particular state to proceed with verification.

cause the synchronizer to be activated, wherein

the synchronizer is stored in a central repository to be reused for one or more other software verification flows, and

21. The machine of claim 18, wherein the at least one processor that is to define the synchronizer struct is further to:

implement the menu item as a widget for the user interface.

22. The machine of claim 21, wherein the at least one processor that is to implement the menu item as a widget is further to:
