Difference Between Regression Testing and Functional Testing In Details

Points of Difference Between Regression Testing and Functional Testing

Daily Batch Processing is a series of mainframe tasks used by a financial institution daily to reunite day to day client dealings.

B is a GUI (Graphical User Interface) program which is used by financial institution workers to evaluation dealings of financial records as per client concerns.

C is a GUI (Graphical User Interface) program which is used by financial institution workers to evaluation dealings of bank card records as per client concerns.

L is a GUI (Graphical User Interface) program which is used by financial institution workers to evaluation dealings of loan records as per client concerns.

Assume that all tasks in batch processing relevant to programs B, C and L are connected each other.

Now there is rule modify for job that procedure program B and this job modify triggered to modify GUI of a B.

Testing Requirements:

Functional Testing:

Now it is evident that evaluators need to test below

1. Jobs that procedure the information to nourish program B

2. Application B GUI rule changes

So the testing of 1 and 2 above is known as Efficient testing i.e any testing to validate the suggested program behaviour is known as functional testing.

Regression Testing:

As we believed above in the importance, the Jobs that procedure information nourish to GUI B is connected to other tasks which procedure information nourishes to C and L. Now it is tester’s liability to make sure that there are no effects to tasks that procedure information nourishes to programs C and L due to rule changes happened on tasks that procedure information nourish to B. So this type of tests known as Regression Testing.

Regression testing and functional testing are all different, in fact. Both form a part of software quality assurance process.

Regression tests the act of retesting a product around an area where a bug was set. If a data access element is modified, for example, to enhance security, the rule straight impacted by that change will be regression examined. A good group will also analyze relevant rule such as UI-based features which make use of the methods and/or category suffering from the fix.

Functional tests an overridden term most frequently used to relate to the testing of application features (functional points) independently. Focus is placed on performance within the product, and very little time is invested testing how that efficient device combines with other efficient models.

Regression testing is a type of application testing that confirms that application previously developed and examined still works properly after it was modified or interfaced with other application. Changes may consist of application improvements, areas, settings changes, etc. During regression testing, new application insects or regressions may be discovered. Sometimes a application package modify impact research is conducted to find out which places could be affected by the suggested changes. These places may consist of efficient and non-functional places of the system.

The purpose of regression testing is to ensure that changes such as those described above have not presented new mistakes. One of the significant reasons for regression testing is to figure out whether a alternation in one part of the application impacts other parts of the software

Functional testing a quality assurance (QA) process and a type of black-box analyzing that angles its analyze cases on the requirements of the software component under analyze. Functions are tested by providing them with food feedback and analyzing the outcome, and internal program structure is rarely considered (not like in white-box testing). Efficient analyzing usually explains what it does.

Functional analyzing does not suggest that you are analyzing a function (method) of your component or class. Efficient analyzing assessments a piece of performance of the whole program.
