Abstract

According to an embodiment of the present invention, a system for generating one or more test cases for a service of a server system comprises at least one processor. The system analyzes metadata associated with the service to generate a schema definition for inputs and outputs of the service. A description of the service is generated in an application description language that refers to the schema definition. The system processes the generated description of the service to produce the one or more test cases. Embodiments of the present invention further include a method and computer program product for generating one or more test cases for a service in substantially the same manner described above.

Claims

1. A computer-implemented method of generating one or more test cases for a service of a server system comprising:

analyzing metadata associated with the service to generate a schema definition for inputs and outputs of the service;

generating a description of the service in an application description language that refers to the schema definition; and

processing the generated description of the service to produce the one or more test cases.

2. The computer-implemented method of claim 1, wherein the service includes an Extract, Transform, Load (ETL) job.

3. The computer-implemented method of claim 1, wherein the schema definition includes an Extensible Markup Language Schema Definition (XSD) grammar, and the application description language includes Web Application Descriptor Language (WADL).

4. The computer-implemented method of claim 1, wherein the one or more test cases include at least one of a test script and a Java application.

5. The computer-implemented method of claim 1, wherein the service is of a third party server system, and the one or more test cases are produced by one or more clients of the service.

6. The computer-implemented method of claim 1, wherein the one or more test cases test at least one of an input parameter and an output of a process of the service for compliance with a data restriction, wherein the data restriction indicates acceptable data for the input parameter and the output.
