Abstract

Embodiments of the present invention provide a method, system and computer program product for a smart cache for server testing in an application development tool. In an embodiment of the invention, method of smart caching of service data during application testing in a development tool for a service invoking application is provided. The method includes loading source code for a computer program into a development tool executing in memory of a computing system. The method further includes executing the source code from the development tool. In this regard, the execution of the source code invokes a service responsive to a directive to invoke the service disposed in the source code. Finally, the method includes invoking the service in a container instance in response to a first invocation of the service from the computer program. However, a data set for the service is located in a cache and returned the data set to the computer program in lieu of invoking the service in the container instance for all other invocations of the service.

Claims

1. A smart caching of service data during application testing in a development tool for a service invoking application, the method comprising:

loading source code for a computer program into a development tool executing in memory of a computing system;

executing the source code from the development tool, the execution of the source code invoking a service responsive to a directive to invoke the service disposed in the source code; and

,

invoking the service in a container instance in response to a first invocation of the service from the computer program, but otherwise locating a data set for the service in a cache and returning the data set to the computer program in lieu of invoking the service in the container instance.

2. The method of claim 1, wherein invoking the service in a container instance in response to a first invocation of the service from the computer program, but otherwise locating a data set for the service in a cache and returning the data set to the computer program in lieu of invoking the service in the container instance, comprises:

determining whether or not a smart cache module has been activated in the container instance;

if the smart cache module has been activated, invoking the service in a container instance in response to a first invocation of the service from the computer program, but otherwise locating a data set for the service in a cache and returning the data set to the computer program in lieu of invoking the service in the container instance; and

,

if the smart cache module has not been activated, invoking the service in the container instance in response to all invocations of the service from the computer program.

3. The method of claim 2, further comprising activating the smart cache module in response to determining that a threshold response time has been exceeded for prior invocations of the service in the container instance.

4. The method of claim 2, further comprising deleting all entries in the cache in response to a de-activation of the smart cache module.

5. The method of claim 2, further comprising deleting the cache in response to a shutdown of the development tool.

6. A software development data processing system comprising:

a computing system comprising memory and at least one processor;

a development tool executing in the memory of the computing system;

a container instance also executing in the memory of the computing system;

a service executing in the container instance;

a cache coupled to the container instance; and

,

a smart cache module executing in the memory of the computing system, the module comprising program code enable to invoke the service in the container instance in response to a first invocation of the service from a computer program executing from source code loaded in the development tool, but otherwise to locate a data set for the service in the cache and return the data set to the computer program in lieu of invoking the service in the container instance.

7. The system of claim 6, wherein the container instance is an application server.

8. The system of claim 6, wherein the source code incorporates asynchronous Javascript and extensible markup language (AJAX) technology.

9. A computer program product for smart caching of service data during application testing in a development tool for a service invoking application, the computer program product comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code for loading source code for a computer program into a development tool executing in memory of a computing system;

computer readable program code for executing the source code from the development tool, the execution of the source code invoking a service responsive to a directive to invoke the service disposed in the source code; and

,

computer readable program code for invoking the service in a container instance in response to a first invocation of the service from the computer program, but otherwise locating a data set for the service in a cache and returning the data set to the computer program in lieu of invoking the service in the container instance.

10. The computer program product of claim 9, wherein the computer readable program code for invoking the service in a container instance in response to a first invocation of the service from the computer program, but otherwise locating a data set for the service in a cache and returning the data set to the computer program in lieu of invoking the service in the container instance, comprises:

computer readable program code for determining whether or not a smart cache module has been activated in the container instance;

computer readable program code for, if the smart cache module has been activated, invoking the service in a container instance in response to a first invocation of the service from the computer program, but otherwise locating a data set for the service in a cache and returning the data set to the computer program in lieu of invoking the service in the container instance; and

,

computer readable program code for, if the smart cache module has not been activated, invoking the service in the container instance in response to all invocations of the service from the computer program.

11. The computer program product of claim 10, further comprising computer readable program code for activating the smart cache module in response to determining that a threshold response time has been exceeded for prior invocations of the service in the container instance.

12. The computer program product of claim 10, further comprising computer readable program code for deleting all entries in the cache in response to a de-activation of the smart cache module.

13. The computer program product of claim 10, further comprising computer readable program code for deleting the cache in response to a shutdown of the development tool.
