Abstract

In some examples, a method may include receiving, by a system comprising a processor, for a first invocation of a first test of a plurality of code coverage tests run at overlapping times, a first report indicating a first subset of files of application code covered by the first test. The method may include generating, by the system, a test-to-file map associating the first subset of files to the first test. The method may include receiving, by the system, a second report indicating a second subset of files of the application code covered by a second invocation of the first test. The method may include modifying, by the system, the test-to-file map to associate the second subset of files to the first test.

Dependent claims

A method comprising:

receiving, by a system comprising a processor, for a first invocation of a first test of a plurality of code coverage tests, a first report indicating a first subset of files of application code covered by the first test, wherein the first invocation of the first test overlaps in time with a second test of the plurality of code coverage tests other than the first test;
generating, by the system, a test-to-file map associating the first subset of files to the first test;
receiving, by the system, a second report indicating a second subset of files of the application code covered by a second invocation of the first test, wherein:
the second invocation of the first test overlaps in time with a third test of the plurality of code invocation tests of the plurality of code coverage tests other than the first test, and
at least one of the overlapping in time of the first invocation of the first test and the second test or the overlapping in time of the second invocation of the first test and the third test causes a given file of a set of files formed from the first subset of files and the second subset of files to be inaccurately indicated in at least one of the first report or the second report as being covered by the first test;
processing, by the system, the set of files based on memberships of the files in the first and second reports to identify the given file, wherein processing the set of files comprises:
for each respective file of the first subset of files, determining an affinity factor (AF);
and
generating, by the system, a report indicating files mapped by the test-to-file map for which the affinity factor (AF) satisfies a threshold;
and
based on the generated report, modifying, by the system, the test-to-file map.

A system comprising:

a processor;
and
a non-transitory storage medium storing instructions that are executable on the processor to:
receive, for a first invocation of a first test of a plurality of code coverage tests, a first report indicating a first subset of files of application code covered by the first test, wherein the first invocation of the first test overlaps in time with a second test of the plurality of code coverage tests other than the first test;
associate the first subset of files to the first test in a test-to-file map;
receive a second report indicating a second subset of files of the application code covered by a second invocation of the first test, wherein:
the second invocation of the first test overlaps in time with a third test of the plurality of code invocation tests of the plurality of code coverage tests other than the first test, and
at least one of the overlapping in time of the first invocation of the first test and the second test or the overlapping in time of the second invocation of the first test and the third test causes a given file of a set of files formed from the first subset of files and the second subset of files to be inaccurately indicated in at least one of the first report or the second report as being covered by the first test;
process the set of files based on memberships of the files in the first and second reports to identify the given file, wherein processing the set of files comprises:
for each respective file of the first subset of files, determining an affinity factor (AF);
and
generating, by the system, a report indicating files mapped by the test-to-file map for which the affinity factor (AF) satisfies a threshold;
and
update the test-to-file map based on the generated report.

receive, for a first invocation of a first test of a plurality of code coverage tests, a first report indicating a first subset of files of application code covered by the first test, wherein the first invocation of the first test overlaps in time with a second test of the plurality of code coverage tests other than the first test;
associate the first subset of files to the first test in a test-to-file map;
receive a second report indicating a second subset of files of the application code covered by a second invocation of the first test, wherein:

at least one of the overlapping in time of the first invocation of the first test and the second test or the overlapping in time of the second invocation of the first test and the third test causes a given file of a set of files formed from the first subset of files and the second subset of files to be inaccurately indicated in at least one of the first report or the second report as being covered by the first test;
