Abstract

A concurrency testcase generation includes providing a concurrency testcase template for features built into a concurrency testcase generation infrastructure that requires no compilation. Through the concurrency testcase template, testers may input directives for managing activities of concurrent threads, directives for configuring timing tests by the concurrent threads, directives for configuring responses to errors by the concurrent threads, and directives for configuring logging of data for the concurrent threads. The directives for managing activities of the concurrent threads may include directives for managing creation of the concurrent threads, directives for customizing actions of each concurrent thread, directives for managing a sequence of the concurrent threads, directives for exchanging of information between the concurrent threads, and directives for configuring throughput for the concurrent threads. The inputted directives collectively define the concurrency testcase. In this manner, the testcase generation infrastructure masks the programming complexities of the features from testers.

Claims

1. A method for concurrency testcase generation by a computer system comprising a processor, comprising:

displaying a concurrency testcase template for features built into a concurrency testcase generation infrastructure that requires no compilation;

receiving first directives input through the concurrency testcase template for managing activities of concurrent threads;

receiving second directives input through the concurrency testcase template for configuring timing tests by the concurrent threads;

receiving third directives input through the concurrency testcase template for configuring responses to errors encountered by the concurrent threads;

receiving fourth directives input through the concurrency testcase template for configuring logging of data for the concurrent threads;

creating a concurrency testcase comprising the first, second, third, and fourth directives by the concurrency testcase generation infrastructure; and

executing the concurrency testcase on an application code by implementing the features built into the concurrency testcase generation infrastructure according to the concurrency testcase, comprising;

implementing one or more of the following features according to the first directives in the concurrency testcase;

assigning tasks to the concurrent threads;

setting a sequence of the concurrent threads;

implementing signaling for exchange of information between the concurrent threads; and

enabling or disabling a thread pool;

implementing a timer according to the second directives in the concurrency testcase to delay task execution until each thread is created;

configuring services to respond to the errors encountered by the concurrent threads according to the third directives in the concurrency testcase; and

implementing a facility to log the data for the concurrent threads according to the fourth directives in the concurrency testcase.
