Analysis of code coverage differences across environments

A method, comprising:

• determining, by a plurality of code coverage agents of a code coverage profiling system, respective agent-specific levels of instrumentation for collecting code coverage data from respective computing resources;
• collecting, from the plurality of agents during a time period, respective code coverage data from the respective computing resources that respective code coverage agents of the plurality of code coverage agents are in, wherein the respective computing resources are associated with execution of a program code of a software product in a first environment, and wherein the respective code coverage data indicates specific portions of the program code that are executed in the respective computing resources and respective frequency of execution of the specific portions at the respective agent-specific levels of instrumentation, and wherein at least a portion of the respective agent-specific levels of instrumentation used in collecting the respective code coverage data from different ones of the plurality of agents are at different levels of granularity of code coverage during the time period;
• merging the respective code coverage data to generate a first code coverage profile comprising the different levels of granularity of code coverage, wherein the first code coverage profile comprises an aggregate of the respective code coverage data, wherein the respective code coverage data are at the respective agent-specific levels of instrumentation, and wherein at least a portion of the respective agent-specific levels of instrumentation for the respective code coverage data are at the different levels of granularity of code coverage;
• and
• performing, by the code coverage profiling system, a comparison of the first code coverage profile and a second code coverage profile associated with execution of the program code in a second environment, to determine a difference between one or more portions of the program code that were executed in the first environment and one or more portions of the program code that were executed in the second environment, wherein the comparison is based, at least in part, on the respective frequency of execution of the specific portions at the respective agent-specific levels of instrumentation.

One or more non-transitory computer-readable storage media storing program instructions that, when executed on or across one or more processors, perform:

• determining, by a plurality of code coverage agents of a code coverage profiling system, respective agent-specific level of instrumentation for collecting code coverage data from respective computing resources;
• collecting, from the plurality of agents during a time period, respective code coverage data from the respective computing resources that respective code coverage agents of the plurality of code coverage agents are in, wherein the respective computing resources are associated with execution of a program code of a software product in a first environment, and wherein the respective code coverage data indicates specific portions of the program code that are executed in the respective computing resources and respective frequency of execution of the specific portions at the respective agent-specific levels of instrumentation, and wherein at least a portion of the respective agent-specific levels of instrumentation used in collecting the respective code coverage data from different ones of the plurality of agents are at different levels of granularity of code coverage during the time period;
• merging the respective code coverage data to generate a first code coverage profile comprising the different levels of granularity of code coverage, wherein the first code coverage profile comprises an aggregate of the respective code coverage data, wherein the respective code coverage data are at the respective agent-specific levels of instrumentation, and wherein at least a portion of the respective agent-specific levels of instrumentation for the respective code coverage data are at the different levels of granularity of code coverage;
• and
• performing, by the code coverage profiling system, a comparison of the first code coverage profile and a second code coverage profile associated with execution of the program code in a second environment, to determine a difference between one or more portions of the program code that were executed in the first environment and one or more portions of the program code that were executed in the second environment, wherein the comparison is based, at least in part, on the respective frequency of execution of the specific portions at the respective agent-specific levels of instrumentation.
