Regression Testing Software
Although before being marketed and released, a certain software program or application has
been through many tests. After all, a company does not want to ruin its reputation by releasing
programs that do no work correctly. However, even programs that originally functioned correctly
will stop doing so and bugs develop. This is more than likely unintentional and results from
changes that have been made to the program script. For this reason it is of utmost importance
that a company makes use of regression testing software and keeps their program working at all
times. Not only that, but software regression testing also provides information on the output
quality and data like simulation time or compilation time can be obtained.
It is a known fact that a program that has been previously fixed all of a sudden shows the problem
once again. This re-emerging of a problem is common and for that reason alone is software
regression testing so important. There are a number of regression testing tools that can be used
to double check a program. A very common method is to just simply re-run previous tests. Going
through the program again should find any re-emerging bugs and problems. Another method is to
record a bug and then program it into a regression testing software program and then the test is
performed whenever a change to the program script occurs. This is important since the bugs
usually re-surface after changes are made. In order to re-test a program on a regular basis, there
are a number of regression testing tools that have been created to complete this task. Automated
testing programs have such tools and regression testing techniques that allow the tester to go
through all regression cases automatically. This is much better and more practical then to do
such regression tests manually, although this can be done if desired. Another very popular and
useful tool that many regression testing software programs have is the one where the system can
be programmed to complete the tests in regular intervals, such as every week or every two
weeks, and then the system reports any bugs found. It is also a good idea to run regression
testing software whenever features have been rewritten, redesigned or compiled.
The most common techniques for running regression testing techniques are the local, unmasked
and remote types. They are use for different purposes and the local one is for newly discovered
bugs whereas the unmasked technique is for the re-discovery of previously found bugs. There
are also two classes of regression. The one is known as the new feature regression and the other
is the existing feature regression.
Regression testing software is necessary to do on a regular basis and it should definitely be done
if any changes have been made to a program or if new features have been added. This testing is
of utmost importance for quality control and if not done, many problems that have been assumed
to be corrected can reappear and if found by others and not you, that can ruin a reputation.
