If you get to know the types of testing functional steps, you will be able to easily understand what functional testing is. You see, functional testing is defined as one of the software development stages. This is part of black box testing wherein the functionality of the software is tested one by one. Of course there are many types of testing functional steps so as to assure that the test is done properly. These are the ones you must be able to understand so that you will be able to come up with the right results.
The first types of testing functional step would be to identify the many different functions of the software. You see, from the onset of the plan to create a software, it is very important that the future functions of the programs be identified and listed. This way, when the software development begins, there will be a guideline that will be followed in the sense of the functions that the programs that it has to perform. When it comes to this part of the types of testing functional steps, it is important that these functions are identified as they will be the ones tested.
Next part of the types of testing functional steps is to create and establishment of the inputs needed to test the functions of the software. You see, there may be a lot of different kinds of input that can be used for this. But it is best that you are able to come up with the ones that will return the output that you desire to be able to see whether or not the functions are working right.
Of course, if input has already been made, a list of the desired output would be the next types of testing functional steps. Remember that you do not create the output. You will merely need to write down what kinds of output will come up when the inputs you have established have been given. This will allow you to see whether or not the software is functioning right.
After you already have identified the inputs and outputs that you will be expecting, the types of testing functional step to follow would be to create the test case. In other words, you will need to enter the inputs that you have established and see there if the software will be coming up with the right expected outputs.
Lastly, as you are already able to get the software to function, you must go on the types of testing functional step that will let you compare your notes. You have already written down what you are expecting the software to do right? Now you have tested them already per functions. Did the software return the right values? Did it give you the right outputs? From here, you can then adjust your software basing on how you want it to react. This way, you will be able to make sure that the functions will be working right as well.
