Why should you shift to functional automation testing?

Why Should You Shift to Functional Automation Testing?

Are you feeling bore to test your code manually for the bugs again & again? The code should function properly is the main thing. If the code is not acting based on the specific requirements? Then is no use with the codes.

Functional testing ensures whether the code functions properly? This is specially based on the requirements. If there is small change or alteration take place in the code? Then it will alter the working. We need to retest our code after every change is made in the code.

When we run the same test cases repeatedly, then it may feel very dampen. This is one of important reason we should prefer the automation testing. Automating our functional testing will be greater relief for us. It reduces our burdens as well as it will save more time.

About Functional Automation Testing:

Let’s first see about what functional testing is. Then we see about functional automation testing.

As we see before, functional testing confirms the working of functions. It confirms whether all function of our code works in based on the requirement. The functional testing needs us to send the appropriate inputs. Also, we need to verify actual output. Especially with expected output.

In the process of quality assurance, we must require repeated testing. For making our work easy, we must automate the process of testing.

This kind of testing automation is a process. This assists us to make things easier as well as faster. Specially to execute our test cases. Generally, manual testing wants us to execute all test case. We need to test this one by one. This is very time-consuming process because we handle it manually.

In order to come out, we go for automating the functional testing. This will be a great savior for saving both time as well as efforts. This will be very helpful in executing all the test cases automatically. Specially without any human intervention.

Now let’s see few drawbacks of the manual testing.

Manual Testing Drawbacks:

Following are few drawbacks of the manual testing. These drawbacks promote the testers for adopting the automated testing. They are,

  • Time taken for the manual testing is much more.
  • Testing like the regression testing are repetitive. Also, this leads the testers to lose their own interest.
  • It needs many resources.
  • This may miss out few scopes of the functional testing.

Need of the Automation Testing:

Now we are going to see the present scenario. Let’s imagine we are developing a software at very fast speed. Also, we are alternating the code based on the requirement. We also enhance our code at equal speed. For this we must require a new method of testing. Especially, to test our code at the same speed. Here the functional automation testing comes to role.

Most of the companies are now going forwarded with Agile as well as DevOps. This increases the importance of the automation. We frequently integrate our codes and enhance our code in this method. These require the test cases to run faster as well as more accurately. The functional automation test provides more accuracy. It runs very faster without any human errors.

One of the biggest reasons for this testing is saving both the time & money.  It provides the feedback very fast to developers. Specially for any of the bugs as well as errors.

It has many more benefits behind the time as well as money saving. Following are some of such benefits. They are,

  • Less fault because of the human error.
  • More actual benchmarks.
  • Assist more reusable.
  • Provides more test coverage.
  • Provides quick feed backs to developers. Especially about the bugs present in the code.
  • Helps to release the software as soon as possible.

Functional automation test as the development of the software:

The Functional automation tests is piece of the software code. These codes rely on the programming language. We can develop the codes as well as test it. Especially with the help of this automaton. It makes the complete activity of the software development.

Developing the codes for the functional testing is not at all an easy job. It is equally complicated as development of the software projects. Also, we need to face same issues as other development.

So, we need to follow the best development practice of the software. This will help us to develop the test cases for the automation testing.

Does it require to automate all our test cases?

It is definitely not at all a good idea to automate all test cases.  We should consider the below things for automating the test cases. They are,

  • Unit test cases.
  • Test cases which are Stress or load.
  • Determining test cases.
  • Time consuming test cases.
  • Test cases which need not require any manual communications.
  • Test cases which needs to run in many browsers, systems and more.
  • Test cases which deals with the areas which are related to the fiscal of software.
  • Test cases which deals with the risk areas of software.
  • Test cases which runs on various data sets.
  • Test cases which seems to be difficult for testing manually.

Also, we must consider the time-consuming & repeating test cases. But these criteria may vary based on the different conditions. 

Now let’s see about the ROI of the Functional automation testing in the below section. 

ROI of the automation functional Automation testing: 

ROI takes place a major part of the business. This is because it controls any decisions of the business. Whether we want to automate our test cases? This will also depend on the ROI. It is very tricky to determine the ROI of the automation testing. There is a small formula to roughly estimate the cost of automation. It is as follows. 

Cost = Tool cost + Labor cost + Maintenance cost.

If our automation testing cost seems lower than cost of manual testing? Then we should go with the automation testing. In case if it seems to be high then ROI get added with each and every run in the automation testing.

Still, there are other factors which affects our decision. Especially, to automate the test cases or not?

What are the test cases which are not to be Automated?

Automation functional testing will definitely save time as well as efforts. But we can’t automate all test cases. This is not at all a good idea. We should not automate few test cases. These are based on the below consideration. They are,

  • Test cases which is to be tested only once.
  • Test cases which doesn’t have any predictive result.
  • Test cases which are based on the Ad Hoc.
  • Usable test cases.

These are considered while we automate the test cases. It is highly beneficial once we done this wisely.


Functional testing is very important phases of the STLC. But sometimes these functional testing take much time as well as frantic task. Automating function testing will help us to overcome from this snag. Also, it will save us more money as well as time. So, I suggest strongly to consider this automation testing for your next projects.
