Abstract

A system and method for simultaneously validating a client-server software application from a client side and a server side, the client-server software application having a client application and a server application. The method and system include: defining a test case to exercise or emulate the client application; specifying validations to be made against server-side state in the defined test case; controlling a monitoring program to monitor the server application and collect information about the server-side state; executing the defined test case to exercise the server application through the client or a client emulator; processing the collected information; simultaneously performing validation tests against the collected information about the server-side state and against the client application or outputs from the server; and reporting results of the validation tests.

Claims

1. A method for simultaneously validating a client-server software application from a client side and a server side, the client-server software application having a client application and a server application, the method comprising:

defining a test case to exercise or emulate the client application;

specifying validations to be made against the client application or outputs from the server in the defined test case;

executing the defined test case to exercise the server application through the client application or a client emulator;

controlling a monitoring program to monitor the server application while being exercised by the execution of the defined test case, and collect information about server-side internal states including execution paths of the server application, wherein the collected information further includes information about an object calling sequence implied from temporal recording of a sequence of calls from the execution of the server application program being exercised by the client application or the emulator;

processing the collected information about the server-side internal states;

retrieving a portion of the processed collected information to recreate instances of server-side objects that have the same properties as the objects in the server application by stubbing portions of the objects that reference information that was not collected by the monitoring program;

defining assertions against properties of said recreated instances of server-side objects, by the test case;

simultaneously performing validation tests against the collected information about the server-side internal states and against the client application using the recreated instances of server-side objects; and

reporting results of the validation tests.

2. The method of claim 1, wherein controlling a monitoring program to monitor the server application and collect information about the server-side internal states further comprises profiling interfaces available for a given program type to provide data about method invocation sequence and argument values.

3. The method of claim 1, wherein defining a test case further comprises using a test tool to define the test case.

4. The method of claim 1, wherein defining a test case further comprises generating corresponding code from an Application Programming Interface (API) that mimics a set of user actions in the client application or by a client emulator.

5. The method of claim 4, wherein the set of user actions are previously recorded in a browser.

6. The method of claim 4, wherein the generated corresponding code is Java code and the API is a HttpUnit API.

7. The method of claim 1, wherein the collected information includes data uniquely identifying a thread in an execution path in which a method is invoked, instance object on which the method was invoked, method argument values, place of the method invocation amongst other method invocations, and return value of the method.

8. The method of claim 7, wherein the collected information further includes information about objects and processes the method would interact with.

9. The method of claim 1, wherein defining a test case further comprises specifying validations to perform on properties of some of the created objects.

10. The method of claim 1, further comprising using the server-side internal states information for trouble-shooting.

11. The method of claim 10, wherein using the server-side internal states information for trouble-shooting further comprises:

specifying portions of the server application to be monitored; and

displaying the collected information in a display.
