REGRESSION TESTING OF APPLICATIONS BASED ON SOURCE CODE CHANGE LOCATIONS AND SOURCE CODE TEST LOCATIONS

An example system includes a source code change engine to: retrieve a source code change location in an application, as maintained at a first database. The example system further includes: a source code test location engine to: retrieve a source code test location, tested by a regression test, as maintained at a second database in association with the regression test. The example system further includes: a regression test selection engine to: select the regression test to test the application based on comparing the source code change location for the application with the source code test location associated with the regression test. The example system further includes: a regression test engine to: execute the regression test, as selected, on the source code test location of the application; and in response to the application passing the regression test, return an indication of passing the regression test.
