Challenges in Development Organizations
• Regressions are run to detect integration errors, however, as a codebase matures
and grows, its regression test suite also grows.
• Running a full regression test on the mature codebase might take hours, slowing
down the frequency of integrations.

Long wait And Trade off..
• Running all tests means long wait for feedback
• Even after running all the tests they cannot tell what part of the code
was tested, or even how much of the application was ever tested
• As such, developers are forced to trade-off software quality for slower
CI cycles or scale down testing and end up with buggy releases
• With DevOps and Agile requiring continuous testing for each and
every build, dev teams need a way to speed up the execution of test
suites

Need..
Need of change impact analysis technique had arisen due to the
inherent difficulty in generating, collating and analysing all the
necessary data required to accurately determine release readiness
(especially in real-time).

• Should provide immediate insights into the tests impacted by code changes
• Should help in prioritizing and executing regression tests based on their efficacy in
detecting bugs.
• Should reduce the total number of tests needed to run
• Eventually should reduce untested code changes from reaching production.

Behind the scene
• Track the code coverage for every single test ,
thereby tracing all the paths for every test that you
ran in your testing suite.
• Track the code changes committed in each build
• Use Machine Learning algorithms on the collected
code Coverage Vs Test(s) map , thus giving the
optimal results of “which test touched which code”.
