Successful businesses plan for a variety of outcomes before ever releasing any product line or changing its operational structure. Ideas are great, but it is important to understand how those ideas are likely to impact the bottom line if acted upon. As you take care of your own business, it is important to know the possible outcomes that will come about before implementing any course of action. Functional testing is a way to do exactly that.

This is a type of testing that introduces a variety of scenarios into any possible software product or idea that you might have to determine what the likely outcomes are. It will also help you to better determine what is acceptable to do in your business and what is best left unused. When you determine what is going to happen, you can make a better determination of what system or software application, you should implement to obtain the desired result. You can use functional testing as a validation for a number of different scenarios that your business is likely to encounter over time.

These Are the Two Most Popular Strategies

If you are looking for the best functional testing tools in use today, the following techniques are the most commonly utilized. Take a look at the description of each and determine which one best suits your needs.

Testing Based on a Business Scenario

You will want to consider this type of functional test when you are considering a software system that will have an impact on the operation of your business. It will employ a number of different scenarios to determine what the most likely outcome will be. Using this type of functional test will allow you to determine how the system is most likely to be perceived by the various operational structures that you have already built into your business. The interesting part of a business scenario functional test is that you can input an outcome that you think might occur and see what happens as a result.

Testing Based on Set Requirements

When you know what you need to get out of a system, this is a type of functional test that will help you determine if you can obtain the necessary outcome or not. Based on that outcome, you can then conduct tests to make sure that the requirements you have in mind will be met.

Both of these testing strategies are most effective when they are implemented in conjunction with your normal quality assurance process. This will help you to get the maximum benefit out of each test in your efforts to determine if the software system under consideration is ready for implementation. It is important to be aware of the different types of functional tests that are possible in order to use the correct one in any given situation. Some tests will need to be run daily, while others will only be necessary at the time of implementation. As such, having a number of tools in your testing arsenal is always advisable.

The Different Types of Functional Tests

As mentioned, it is important to understand that there are a number of functional tests that can be deployed by any given business. The actual test that you end up using will depend on the scenario being studied. Whoever does the testing should be aware of each of these types and understand how best to use them in any given situation.

Beta and Usability

No product should ever be delivered to the customer in its final form before it is first tested in a real-world environment. This is what the beta functional test is designed to measure. You will be able to determine how usable the product is, and you can spot any potential problem areas before it gets delivered to the client.


Many software systems require other external components in order to work properly. These must integrate well together in order to make sure that the system produces the desired outcome. An integration test is designed to make sure that each part of the product works well with all other required components. If there is a breakdown anywhere along the way, this is the type of test that will reveal it. At that point, you can then make any necessary adjustments.


You might have an existing software system that is working well, but you encounter the need to add some additional code to it. Before this is then released back to the general public, you must run a regression test. You need to ensure that the new code performs the desired function and that it does not compromise any other parts of the system. You need to ensure that the product is still going to run as advertised.


Smoke testing should occur when the system has been completed, and you think that it is ready to go. This is a test that is designed to put the product through almost every type of situation imaginable in order to make sure that it performs as it should. In essence, smoke testing is such a useful UFT tool because it helps you to determine the overall stability of the entire system.


This is a useful functional test because it makes sure that the system is working even after you have released it. It is important to continue with the testing process on a periodic basis just to make sure that the application is continuing to deliver the desired outcome each and every time. Sanity testing is typically performed after a smoke test in order to provide a type of verification process.

You will want to view functional testing as an essential part of the business process. You need to have a way to ensure that your systems are working properly and that you are representing yourself well to your customers. Functional testing is a way to spot potential problems before they get released and cause you further headaches down the road.
