Along with Software Development, software testing is also one of the most important factors that plays crucial role. There are many different methods for software testing. Let us take a look at Regression testing today.
Regression testing is one kind of software testing procedure that seeks to expose regression bugs/errors. Regression bugs arise whenever software functionality that worked fine in the past stops operating or no longer works in the similar way that was previously intended. Normally regression bugs arise as an accidental outcome of program changes.
The most common techniques of regression testing comprises re-running formerly run tests and checking whether formerly-fixed mistakes/defects have resurfaced. Previous experiences have revealed that as software is developed; such type of reemergence of bugs/defects is quite normal. Sometimes it arises because a fix gets vanished through improper/inadequate revision control exercises (or simple human mistake in review control), but just as often a solution for a trouble will be "delicate" - if some other modification is made to the program, the fix no longer performs.
Ultimately, it has frequently been the case that when some feature is revamped, the same errors will be made in the revamped solution that were made in the initial execution of the feature. So, in most software development states it is considered good exercise that when a bug is found and fixed, a test that exposes the error is traced and frequently retested after subsequent modifications to the program.
Although this may be completed through manual testing processes using programming methods, it is often done by automatic testing techniques, frequently, a 'test suite', software techniques that lets the testing environment to carry out all the regression test occurrences automatically; some assignments even set up automated mechanisms to automatically re-run all regression tests at stipulated times and report any regressions that arises.
Common approaches are to run such a mechanism after every successful compile (for small projects), each night, or once a week. Regression testing is an essential part of the considerable programming software development techniques. In this testing methodology, design documents are exchanged by extensive, repeatable, and automated testing of the whole software package at every phase in the software development life cycle.
