Testcase Synchronization via Phase Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Software testing in enterprise data processing environments is time-consuming due to the complexity of modern software applications and the need to execute testcases across multiple hosts and platforms, often resulting in race conditions that require synchronization of testcase processes.
Innovation Solution
A method for executing testcases in a sequence of phases with asynchronous execution across multiple processes, using synchronization events triggered externally to manage synchronization, allowing each phase to initiate only upon completion of the previous phase, thereby mitigating race conditions.

1Productivity
If testcases are executed across multiple hosts and platforms simultaneously, then testing coverage and productivity are improved, but race conditions occur requiring complex synchronization mechanisms
Solution Approach 1:
The testcase is divided into multiple phases, where each phase represents a distinct execution stage. This segmentation allows different phases to be executed independently on different hosts while maintaining a clear execution sequence, thereby enabling parallel testing without race conditions between phases.
Solution Approach 2:
A synchronization event is established before each phase execution to ensure that all processes are ready and properly initialized before the phase begins. This preliminary synchronization action prevents race conditions by ensuring consistent initial states across all hosts before execution starts.
2Productivity
If multiple testcase processes execute concurrently to cover multiple platforms, then testing throughput increases, but synchronization complexity increases to manage race conditions
Solution Approach 1:
A centralized synchronization event acts as an intermediary between all testcase processes. Instead of each process managing its own synchronization, the external synchronization event coordinates all phase transitions, simplifying the synchronization mechanism while enabling concurrent execution across multiple platforms.
Solution Approach 2:
Multiple synchronization requirements are merged into a single external synchronization event that all processes wait for. This consolidation reduces the complexity of managing multiple synchronization mechanisms while maintaining the ability to execute testcases concurrently across different hosts and platforms.
3Reliability
If testcases are broken into phases for synchronized execution, then race conditions are mitigated, but execution time increases due to sequential phase dependencies
Solution Approach 1:
The execution model dynamically adapts to platform-specific requirements while maintaining phase synchronization. Each phase can be executed asynchronously on different hosts once the synchronization event is triggered, allowing the system to optimize execution time while preserving the correctness guarantees of synchronized phase transitions.

AI summary
Systems and methods for software automation are provided. Software testcases are distributed across multiple data processing systems (equivalently, “machines” or “hosts”) that may collectively include multiple platforms (equivalently, “operating systems”). A testcase may be executed as one or more processes progressing through a sequence of phases, with execution within a phase being asynchronous among processes. Synchronization of the testcase processes across the data processing systems and platforms may be effected by managing an event; the testcase processes block on the event upon completion of the current testcase phase. A testcase phase execution service on each host handles synchronization events. The definition of the testcase may include metadata that identifies the particular phases in sequence, that is phase names, for the testcase; the phase names identifies the phases to the synchronization process that triggers the synchronization events which initiate each succeeding phase of the testcase.
