Abstract

Systems and methods for test data generation are described. In one implementation, the method includes receiving seed data having one or more characteristics. Further, the method includes obtaining a selection criterion indicating a selected portion of the seed data to be transformed. Based on the selection criterion, the seed data is transformed for at least a plurality of iterations to generate test data. The test data comprise a plurality of data sets including a primary data set generated in a first iteration and a secondary data set generated in each subsequent iteration. The primary data set includes transformed data corresponding to the selected portion of the seed data and non-transformed data corresponding to a remaining portion of the seed data and each secondary data set includes transformed data corresponding to the selected portion of the seed data.

Claims

1. A method for generating test data comprising:

receiving seed data having one or more characteristics;

obtaining a selection criterion indicating a selected portion of the seed data to be transformed; and

transforming the seed data for at least a plurality of iterations to generate test data, wherein the test data comprise a plurality of data sets including a primary data set generated in a first iteration and a secondary data set generated in each subsequent iteration such that the primary data set includes transformed data corresponding to the selected portion of the seed data and non-transformed data corresponding to a remaining portion of the seed data and each secondary data set includes transformed data corresponding to the selected portion of the seed data.

2. The method as claimed in claim 1 further comprising loading the test data in a test database, wherein the loading comprises:

transferring the primary data set into the test database;

appending the non-transformed data in the primary data set to the transformed data in the secondary data set to generate a temporary data set;

further transferring the temporary data set into the test database; and

deleting the temporary data set.

3. The method as claimed in claim 1, wherein the plurality of iterations is based on volume of the test data to be generated.

4. The method as claimed in claim 1, wherein the characteristics includes cell level characteristics, column level characteristics, and inter-column level characteristics.

5. The method as claimed in claim 1, wherein the seed data is based at least in part on production data.

6. The method as claimed in claim 1, wherein the seed data seed data is based at least in part on user-defined data.

7. A test data generation system comprising:

a processor;

a memory coupled to the processor, wherein the memory comprises

a transformation module configured to transform seed data for at least a plurality of iterations to generate test data, wherein the test data comprise a plurality of data sets including a primary data set generated in a first iteration and a secondary data set generated in each subsequent iteration such that the primary data set includes transformed data corresponding to the selected portion of the seed data and non-transformed data corresponding to a remaining portion of the seed data and each secondary data set includes transformed data corresponding to the selected portion of the seed data.

8. The test data generation system as claimed in claim 7 further comprises a loading module configured to:

transfer the primary data set into a test database;

append the non-transformed data in the primary data set to the transformed data in the secondary data set to generate a temporary data set;

further transfer the temporary data set into the test database; and

delete the temporary data set.

9. The test data generation system as claimed in claim 7, wherein the transformation module comprises one or more converters configured to generate the plurality of data sets including at least one of cell level characteristics and column level characteristics of the seed data.

10. The test data generation system as claimed in claim 7, wherein the transformation module comprises one or more synthesizers configured to generate the plurality of data sets including at least inter-column characteristics.

11. A computer-readable medium having embodied thereon a computer program for executing a method comprising:

receiving seed data having one or more characteristics;

obtaining a selection criterion indicating a selected portion of the seed data to be transformed; and

transforming the seed data for at least a plurality of iterations to generate test data, wherein the test data comprise a plurality of data sets including a primary data set generated in a first iteration and a secondary data set generated in each subsequent iteration such that the primary data set includes transformed data corresponding to the selected portion of the seed data and non-transformed data corresponding to a remaining portion of the seed data and each secondary data set includes transformed data corresponding to the selected portion of the seed data.

12. The computer-readable medium as claimed in claim 11 further comprising loading the test data in a test database, wherein the loading comprises:

transferring the primary data set into the test database;

appending the non-transformed data in the primary data set to the transformed data in the secondary data set to generate a temporary data set;

further transferring the temporary data set into the test database; and

deleting the temporary data set.

13. The computer-readable medium as claimed in claim 11, wherein the plurality of iterations is based on volume of the test data to be generated.

14. The computer-readable medium as claimed in claim 11, wherein the characteristics includes cell level characteristics, column level characteristics, and inter-column level characteristics.

15. The computer-readable medium as claimed in claim 11, wherein the seed data is based at least in part on production data.

16. The computer-readable medium as claimed in claim 11, wherein the seed data seed data is based at least in part on user-defined data.
