Abstract
Official abstract text for this publication.
A computer-implemented method, computer program product, and system is provided for determining test coverage. In an implementation, a method may include identifying at least one change in source code. The method may also include instrumenting object code of at least one class file associated with a source file of the source code associated with the identified at least one change. The method may further include testing the instrumented object code with at least one test case. The method may further include generating a coverage report associated with the instrumented object code, wherein the coverage report includes a proportion of the at least one change in the source code covered by the at least one test case.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer-implemented method comprising: identifying, by a processor, at least one change in source code; identifying, by the processor, object code of at least one class file associated with a source file of the source code associated with the identified at least one change, wherein the object code of at least one class file is a compiled file of the source code; instrumenting, by the processor, the object code of the at least one class file associated with the source file of the source code associated with the identified at least one change; inserting a counter into the object code of the at least one class file associated with the source file of the source code associated with the identified at least one change, wherein the counter is increased each time a portion of an instruction associated with the object code is executed; testing, by the processor, the instrumented object code with at least one test case; and generating, by the processor, a coverage report associated with the instrumented object code, wherein the coverage report includes a proportion of the at least one change in the source code covered by the at least one test case. 2. The computer-implemented method of claim 1 , wherein identifying the at least one change in the source code includes identifying the at least one change in the source code based upon, at least in part, a source code history change-set. 3. The computer-implemented method of claim 1 , wherein the at least one change in the source code includes at least one of a new source file and at least one change in an existing source file. 4. The computer-implemented method of claim 3 , further including: identifying the at least one class file associated with the source file of the source code associated with the at least one change based upon, at least in part, a source code attribute of the at least one class file. 5. The computer-implemented method of claim 4 , wherein instrumenting the object code of the at least one class file associated with the source file of the source code associated with the identified at least one change further includes: instrumenting the object code associated with the at least one class file associated with the new source file. 6. The computer-implemented method of claim 4 , wherein instrumenting the object code of the at least one class file associated with the source file of the source code associated with the identified at least one change further includes: instrumenting the object code associated with the at least one class file associated with the at least one change in the existing source file.
