Abstract

Devices and methods for identifying relevant features of software product are described. The system retrieves requirement data, test case data and defect data associated with plurality of features of the software product. The requirement data comprises de-scoped requirements which indicate those requirements which are not required for performing the regression testing. The device further computes an impact score, a test effort score, and a weightage factor for each of the plurality of features based on the requirement data, the test case data and the defect data respectively. Based on the computed impact score, the test effort score, and the weightage factor, the device further determines a regression factor for each of the plurality of features. Further, the device identifies one or more relevant features amongst the plurality of features based on the regression factor. This way, the device facilitates structured regression planning which optimizes the overall performance of the device.

Claims

1. A method for identifying relevant features of a software product for regression testing, the method comprising:

retrieving, by a software testing computing device, requirement data, test case data and defect data associated with a plurality of features of the software product, wherein the requirement data comprises one or more new requirements, one or more updated requirements, one or more impacted requirements, and one or more de-scoped requirements, and wherein the de-scoped requirements indicates a set of requirements not required for performing the regression testing;

computing, by the software testing computing device, an impact score, a test effort score, and a weightage factor for each of the plurality of features based on the requirement data, the test case data and the defect data respectively, wherein the impact score is computed by excluding the one or more de-scoped requirements from the one or more new requirements, and adding the one or more updated requirements with the one or more impacted requirements;

determining, by the software testing computing device, a regression factor for each of the plurality of features based on the impact score, the test effort score, and the weightage factor;

identifying, by the software testing computing device, one or more relevant features amongst the plurality of features based on the regression factor; and

testing, by the software testing computing device, only the identified one or more relevant features of the software product.

2. The method as claimed in claim 1, wherein the requirement data, the test case data and the defect data are retrieved from a test management repository associated with the software testing computing device.

3. The method as claimed in claim 1, wherein test case data comprises one or more existing test cases, one or more new test cases, one or more updated test cases, and one or more deleted test cases based on the de-scoped requirements.

4. The method as claimed in claim 1, wherein the defect data comprises one or more user acceptance testing defect data indicating defect detected during user acceptance testing, one or more production defect data indicating defect detected in production stage, and one or more quality assurance defect data indicating defect detected in quality assurance stage.

5. The method as claimed in claim 4, further comprising determining a priority of each of the plurality of features based on the one or more user acceptance testing defect data, the one or more production defect data, and the one or more quality assurance defect data.

6. The method as claimed in claim 1, wherein the identifying the one or more relevant features comprises:

comparing, by the software testing computing device, the regression factor of each of the plurality of features with a predefined regression factor range.

7. A software testing computing device comprising:

a processor; and

a memory communicatively coupled to the processor, wherein the memory stores processor-executable instructions, which, on execution, causes the processor to;

retrieve requirement data, test case data and defect data associated with a plurality of features of the software product, wherein the requirement data comprises one or more new requirements, one or more updated requirements, one or more impacted requirements and one or more de-scoped requirements, and wherein the de-scoped requirements indicate a set of requirements not required for performing the regression testing;

compute an impact score, a test effort score, and a weightage factor for each of the plurality of features based on the requirement data, the test case data and the defect data respectively, wherein the impact score is computed by excluding the one or more de-scoped requirements from the one or more new requirements, and adding the one or more updated requirements with the one or more impacted requirements;

determine a regression factor for each of the plurality of features based on the impact score, the test effort score, and the weightage factor;

identify one or more relevant features amongst the plurality of features based on the regression factor; and

test only the identified one or more relevant features of the software product.

8. The device as claimed in claim 7, wherein the requirement data, the test case data and the defect data are retrieved from a test management repository associated with the software testing system.

9. The device as claimed in claim 7, wherein test case data comprises one or more existing test cases, one or more new test cases, one or more updated test cases, and one or more deleted test cases based on the de-scoped requirements.

10. The device as claimed in claim 7, wherein the defect data comprises one or more user acceptance testing defect data indicating defect detected during user acceptance testing, one or more production defect data indicating defect detected during production stage, and one or more quality assurance defect data indicating defect detected during quality assurance stage.

11. The device as claimed in claim 10, wherein the processor is further configured to determine priority of each of the plurality of features based on the one or more user acceptance testing defect data, the one or more production defect data, and the one or more quality assurance defect data.

12. The device as claimed in claim 7, wherein the processor is further configured to identify the one or more relevant features by comparing the regression factor of each of the plurality of features with a predefined regression factor range.

13. A non-transitory computer-readable storage medium including instructions stored thereon that when processed by at least one processor cause a software testing system to perform operations comprising:

retrieving requirement data, test case data and defect data associated with a plurality of features of the software product, wherein the requirement data comprises one or more new requirements, one or more updated requirements, one or more impacted requirements, and one or more de-scoped requirements, and wherein the de-scoped requirements indicates a set of requirements not required for performing the regression testing;

computing an impact score, a test effort score, and a weightage factor for each of the plurality of features based on the requirement data, the test case data and the defect data respectively, wherein the impact score is computed by excluding the one or more de-scoped requirements from the one or more new requirements, and adding the one or more updated requirements with the one or more impacted requirements;

determining a regression factor for each of the plurality of features based on the impact score, the test effort score, and the weightage factor;

identifying one or more relevant features amongst the plurality of features based on the regression factor; and

testing only the identified one or more relevant features of the software product.

14. The medium as claimed in claim 13, wherein the requirement data, the test case data and the defect data are retrieved from a test management repository associated with the software testing system.
