Abstract

This document discusses, among other things, a method of testing an Application Programming Interface (API) call that includes receiving data identifying a schema associated with web services together with an API call. Various example embodiments may relate to accessing a data repository associated with the schema to identify an API response corresponding to the API call. In some example embodiments, a message is returned that is based on a determination of whether the API call is valid. The example message may simulate an API response from web services.

Claims

1. A method of testing an application programming interface (API) call, comprising:

receiving an API call to access at least one web service, the API call indicating a schema associated with the at least one web service;

validating the API call based on the schema; and

based on validating the API call, providing a simulated API response that simulates an API response from the at least one web service.

2. The method of claim 1, wherein the API call includes at least one input field.

3. The method of claim 2, wherein validating the API call includes verifying at least one of:

that the input field is populated with at least one value; and

that the input field is associated with a valid extensible markup language (XML) schema data type.

4. The method of claim 1, wherein the API call corresponds to instructions executable by the at least on web service to perform a function.

5. The method of claim 1, wherein the validating of the API call includes validating the API call based on syntax of the schema.

6. The method of claim 1, wherein the providing of the simulated API response includes generating the simulated API response including at least one output field populated with a value.

7. The method of claim 1, further comprising:

returning an error message based on invalidating the API call that is not consistent with syntax of the schema.

8. The method of claim 7, wherein the receiving of the API call includes receiving the API call via a world wide web (WWW) from a web browser, and the returning of the simulated response or the error message includes returning the simulated response or the error message to the web browser.

9. The method of claim 7, wherein the receiving of the API call includes receiving the API call via a world wide web (WWW) from a desktop interface, and the returning of the simulated response or the error message includes returning the simulated response or the error message to the desktop interface.

10. A machine-readable medium having executable instructions to cause one or more machines to perform a method of testing an application programming interface (API) call, the method comprising:

receiving an API call to access at least tine web service, the PI call indicating a schema associated with the at least one web service;

validating the API call based on the schema; and

based on validating the API call, providing a simulated API response that simulates an API response from the at least one web service.

11. The machine-readable medium of claim 10, wherein the API call includes at least one input field.

12. The machine-readable medium of claim 11, wherein validating the API call includes verifying at least one of:

that the input field is populated with at least one value; and

that the input field is associated with a valid extensible markup language (XML) schema data type.

13. The machine-readable medium of claim 10, wherein the API call corresponds to instructions executable by the at least one web service to perform a function.

14. The machine-readable medium of claim 10, wherein the validating of the API call includes validating the API call based on syntax of the schema.

15. The machine-readable medium of claim 10, wherein the providing of the simulated API response includes generating the simulated API response including at least one output field populated with a value.

16. The machine-readable medium of claim 10, further comprising:

returning an error message based on invalidating the API call that is not consistent with syntax of the schema.

17. A response simulator to test an Application Programming Interface (API) call, the response simulator comprising:

a communication interlace to be communicatively coupled to a user interface and to receive from the user interface;

an API call to access at least one web service, the API call indicating a schema associated with the at least one web service;

a validation module communicatively coupled to the communication interface to determine whether the API call is valid; and

a response module communicatively coupled to the validation module and to the communication interface to provide a simulated API response based on validating the API call, the simulated API response simulating an API response from the at least one web service.

18. The response simulator of claim 17, wherein the API call includes at least one input field populated with a value.

19. The response simulator of claim 18, wherein the validation module is to determine the valid API call based on verifying at least one of:

that the input field is populated with at least one value; and

that the input field is associated with a valid extensible markup language (XML) schema data type.

20. The response simulator of claim 17, wherein the API call corresponds to instructions executable by the web services to perform a function.

21. The response simulator of claim 17, wherein the validation module is to validate the API call based on syntax of the schema.

22. The response simulator of claim 17, wherein the response module is to indicate failure or partial success of the API call, based on comparing the API call with syntax of the schema.

23. The response simulator of claim 22, wherein the communication module is to receive the API call via a world wide web (WWW) from a web browser, and the communication module is to return the indication of failure or partial success of the API call to the web browser via the WWW.

24. The response simulator of claim 22, wherein the communication module is to receive the API call via a world wide web (WWW) from a desktop program interface, and the communication module is to return the indication of failure or partial success of the API call to the desktop program interface via the WWW.

25. The response simulator of claim 17, wherein the response module is to generate the simulated API response that includes at least one output field populated with a value.

26. The response simulator of claim 17, wherein the response simulator is integrated into a desktop program via installation of a plugin to the desktop program, wherein the desktop program is included within the user interface.

27. A system to test an application programming interface (API) call, comprising:

receiving means for receiving an API call to access at least one web service, the API call indicating a schema associated with the at least one web service;

validating means for validating the API call based on the schema; and

based on validating the API call, responsive means for providing a simulated API response that simulates an API response from the at least one web service.
