Abstract

A system and method of dynamically generating software is provided. Applications are created in a set of workflow models which are tested in an interpretive test environment. The models are stored in a versioning repository and code generation templates created for the models. Source code is generated and compiled for the application. Modifications to the models are tested and incorporated into a modified version of the application after subsequent testing of the model and the modified, compiled application. The modified version of the application is returned to the test environment where it becomes the basis for testing future modifications.

Claims

1. A computer-implemented method of providing an application based on a workflow, comprising:

under control of one or more computer systems configured with executable instructions,

obtaining one or more models of a workflow;

generating source code based on the one or more models;

compiling the source code to provide compiled code;

modifying at least one of the one more models to provide at least one modified model;

reconfiguring the compiled code to provide an interpreted component to operate with the at least one modified model via interpretation and an unchanged component to operate via direct execution by a processor;

interpreting the interpreted component and the at least one modified model;

executing the unchanged component by the processor; and

providing an application including the at least one modified model.

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

obtaining instructions for testing the application; and

testing the application in a testing environment based at least in part upon the instructions.

3. The computer-implemented method of claim 2, wherein the instructions are obtained from a user.

4. The computer-implemented method of claim 2, wherein the instructions are obtained from a unit testing framework.

5. The method of claim 2, further comprising:

deploying the application to a production environment.

6. The computer-implemented method of claim 1, wherein generating the source code includes:

obtaining one or more code generation templates based on the one or more models; and

executing a code generator using the one or more code generation templates.

7. The computer-implemented method of claim 6, wherein the code generation templates are obtained from a user.

8. The computer-implemented method of claim 6, wherein the code generation templates are obtained from a template repository.

9. The computer-implemented method of claim 6, wherein providing the application includes:

modifying the one or more code generation templates to provide one or more modified code generation templates based on the at least one modified model;

generating modified source code using the one or more modified code generation templates; and

compiling the modified source code to provide the application.

10. The computer-implemented method of claim 9, further comprising:

providing a notification relating to the one or more modified code generation templates.

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

storing the one or more models in a model repository including versioning information; and

storing the at least one modified model as a subsequent version of the at least one of the one or more models.

12. A system, comprising:

a processor;

memory including instructions that, upon being executed by the processor, cause the system to;

obtain one or more models of a workflow;

generate source code based on the one or more models;

compile the source code to provide compiled code;

modify at least one of the one more models to provide at least one modified model;

reconfigure the compiled code to provide an interpreted component to operate with the at least one modified model via interpretation and an unchanged component to operate via direct execution by a processor;

interpret the interpreted component and the at least one modified model;

execute the unchanged component by the processor; and

provide an application including the at least one modified model.

13. The system of claim 12, wherein the instructions upon being executed further cause the system to:

obtain information for testing the application; and

test the application in a testing environment based at least in part upon the information.

14. The system of claim 13, wherein the information is obtained from at least one of a user or a unit testing framework.

15. The system of claim 12, wherein the one or more models and the at least one modified model correspond to an interchange format.

16. The system of claim 12, wherein the instructions upon being executed to cause the system to generate the source code include causing the system to:

obtain one or more code generation templates based on the one or more models; and

execute a code generator using the one or more code generation templates.

17. The system of claim 16, wherein the instructions upon being executed further cause the system to:

store the one or more code generation templates in a version tracking repository.

18. A non-transitory computer-readable storage medium including instructions that, upon being executed by a processor, cause the processor to:

obtain one or more models of a workflow;

generate source code based on the one or more models;

compile the source code to provide compiled code;

modify at least one of the one more models to provide at least one modified model;

reconfigure the compiled code to provide an interpreted component to operate with the at least one modified model via interpretation and an unchanged component to operate via direct execution by a processor;

interpret the interpreted component and the at least one modified model;

execute the unchanged component by the processor; and

provide an application including the at least one modified model.

19. The non-transitory computer-readable storage medium of claim 18, wherein the instructions upon being executed further cause the processor to:

obtain instructions for testing the application; and

test the application in a testing environment based at least in part upon the instructions.

20. The non-transitory computer-readable storage medium of claim 18, wherein the instructions upon being executed to cause the processor to provide the application include causing the processor to:

modify one or more code generation templates to provide one or more modified code generation templates based on the at least one modified model;

generate modified source code using the one or more modified code generation templates; and

compile the modified source code to provide the application.
