Manual vs Automation Testing: Do You Need Both?

Manual vs Automation Testing: Do You Need Both?

Whenever you launch a digital product to the market, you have to be 100% certain it should work easily and flawlessly. And, in fact, it ought to meet the expectations of your customers too! In any other case, your challenge might fail, which is not the desired end result, proper? So that you must pay due consideration to software program QA testing.



However what’s the proper method to testing your platform? Which methods to pick out? Is it price checking product efficiency manually or utilizing automation? Or possibly select each choices without delay?

These are tough questions, however don’t fret: we’re able to reply them in correct order.

What’s automated and handbook testing?

Making certain high-quality software program is a posh course of, which takes a whole lot of time and prices some cash. Nevertheless, such bills can’t be prevented (offered you need to reach the long term). You will need to draw up a reliable testing technique that will let you get the utmost impact with minimal effort and perceive whether or not the location or utility meets the necessities set.

And initially, it is best to reply the query: are you going to check software program manually or utilizing course of automation?

How do the automated and handbook testing differ?

  • With a handbook method, testing is being carried out with out utilizing software program;
  • With automated software program testing, the method is predicated on particular scripts.

Each sorts of testing have professionals and cons, which we will focus on on a case-by-case foundation. For now, let’s simply say that the profitable implementation of the challenge largely depends upon the time, value, and high quality of labor. The problem for the enterprise proprietor is to cut back the fee and growth time whereas sustaining its high quality. And testing additionally performs a task on this regard.

Handbook Testing

As you could have discovered, this sort of testing does not contain the usage of automation instruments. The testing engineer interacts with the digital product straight and works with it because the end-user.

Though handbook testing is sort of low-level, it can’t be uncared for. The actual fact is that complete automation is simply unimaginable… nevertheless, let’s focus on the issue in additional element.

The primary process of handbook testing

A key objective is to ensure the software program works as supposed. And consider us, it is not about mindlessly clicking on web site hyperlinks and tapping app display screen parts. You need to draw up a reliable technique and act in response to the plan.

So whereas a handbook QA professional isn’t required to have particular data, he have to be sensible and discerning.

Format testing is extraordinarily vital, do not you agree? Then we suggest to debate what instruments are finest to make use of to attain one of the best outcome.

Handbook Software program Testing Myths:

  • anybody can check a product manually. Alas, that is removed from the reality. A QA engineer should have expertise and be skilled sufficient;
  • automation is the one key to effectivity. Really, each sorts of testing are vital and efficient in their very own approach;
  • handbook testing could be very simple. It appears easy, however simply at first look. An analytical method is required anyway so that you simply don’t should do pointless work and delay the event course of.

Execs and cons of handbook testing

Let’s begin with the advantages, do you thoughts?


  • No programming data required. Many testing duties of this type could be carried out with out entry to the code. So discovering the fitting specialist is way simpler.
  • Well timed person suggestions. A handbook tester acts as an end-user who’s as important as attainable to your product and tries to search out a whole lot of flaws in it. So that you get rapid person suggestions and have an opportunity to enhance your platform earlier than an actual buyer interacts with it.
  • Cheapness. You don’t want to purchase or create automation instruments, which suggests you save in the beginning (solely within the quick time period).
    • The value of handbook testing is fairly low, however not in the long term! Maintain this in thoughts.
  • Actual-time outcomes. The QA engineer does not write check instances so he does not want to attend for his or her completion. He is capable of present some outcomes right here and now, immediately.
  • Excessive-quality UI suggestions. Person interface testing can solely be completed manually (a minimum of, for now). Automating the method would neither give excellent outcomes nor let you modify your design in response to the expectations of customers.
  • Efficient exploratory testing. Along with the testing of software program interfaces, there’s a likelihood to investigate the operation of an utility or web site from the viewpoint of a researcher and consider its performance. And on this case, the essential factor is spontaneity, which could not be achieved in the event you run automated testing.
  • Improvisation. Properly, the final instance of the advantages of handbook testing is improvisation. Basically, this is similar spontaneity we have talked about above. Automation is all the time based mostly on deliberate eventualities, whereas a handbook method opens up room for creativeness and spontaneous selections.


  • Human errors. We, the individuals, typically make errors merely by advantage of our human nature. That is fairly regular.
  • Longer course of period. As we have talked about earlier, some outcomes could also be offered instantly, however these are largely preliminary information. Generally, the entire process takes for much longer (in comparison with the automated course of).
  • No circumstances for finishing up efficiency or stress testing. Handbook methods do not enable simulating numerous customers, so that you’re unable to learn the way the system would behave when the load will increase.
  • Impossibility of reuse. Every subsequent collection of exams must be carried out anew, and it’ll take the identical period of time.
  • Extra prices in the long term. Because the time of the QA professional’s work grows, the price of the challenge does the identical. At first, although, no particular investments are anticipated.

The place do you have to use handbook testing eventualities?

  • The necessity for bodily affect. If the testing course of requires some type of bodily affect from a QA professional (switching connectors, turning a tool on and off, and many others.), it is simpler and cheaper to resort to a handbook method.
  • Safety. Safety testing must also embrace handbook methods. The purpose is, there are eventualities the place the person is proven a particular modal window to work together with. And no different utility sees it (which is being completed in order that no program may intervene with the safety system). As you may think about, computerization is unlikely that can assist you right here, you want a human tester!
  • UI/UX. If person expertise or person interface testing are wanted, you will should dismiss automating the method too. Solely a handbook testing engineer would spot errors in enterprise logic or design.
    • In actual fact, there are particular frameworks capable of simulate person conduct (keystrokes, mouse motion, clicking on hyperlinks, and many others.). Nevertheless, they don’t seem to be efficient sufficient to rely solely on the outcomes they supply us with.
  • Quick testing. You’ll be able to write a testing script provided that you perceive what the ultimate outcome ought to seem like. If the function is new, it is troublesome to foretell the result, and it is higher to start out with handbook eventualities.

Automated Testing

We always try to automate and thereby simplify some actions and operations, and the work of a QA professional isn’t any exception. Furthermore, handbook scripts are hardly sufficient to create a challenge’s testing technique able to guaranteeing the sleek operation of contemporary multi-component software program programs.

Nonetheless additional, much less and fewer time is dedicated to the event of digital merchandise, which suggests testing have to be carried out shortly and effectively. And its automation is a superb reply to this sort of problem of our time.

What’s Automation Testing?

Automation of the QA engineer’s actions includes the usage of particular software program (along with the examined one) and writing varied exams. The complete course of depends on a pre-scripted situation, so there isn’t any room for spontaneity… but it surely has different advantages that we’ve but to debate.

Why is automated testing so demanded?

  • Accelerated software program growth course of. As we have already mentioned, the software program is developed sooner as we speak, so a QA professional must be extra dexterous in checking the standard of its work.
  • The recognition of DevOps expertise, the essence of which lies within the tight integration of all growth phases. Subsequently, testing of a digital product must be carried out concurrently with its creation. And automation is indispensable on this respect.
  • The complication of software program. At the moment, modern applied sciences similar to large information, IoT, and the like are getting used an increasing number of actively. As well as, microservices structure has turn into widespread, which permits completely different options to be developed independently of one another. Checking the operation of each microservice is simply too troublesome a process, and a handbook tester will not have the ability to address it.

In the event you nonetheless don’t perceive who and why wants testing, it is best to rigorously learn our article on the hyperlink.


To write down automated exams, a QA specialist should have programming abilities. The work is fairly fascinating as a result of the professional has to provide you with efficient and unique methods to make use of automated testing instruments.

Execs and cons of automated testing

Now it’s time to debate the primary benefits and drawbacks of automated testing.


  • Risk of efficiency and stress testing. In contrast to handbook eventualities, computerized processes are ideally suited to simulate the loading affect of numerous customers;
  • No danger of human errors. Automated testing methods aren’t susceptible to the errors that an individual unwittingly makes;
  • Saving time. Automation is designed to simplify and pace up a specific course of (on this case, checking the operation of a digital product);
  • Reuse. As soon as you have written a check script, you’re welcome to make use of it again and again as many instances as you want;
  • No routine. The advantages of automated testing additionally supply an important likelihood to keep away from boredom and routine so consultants get drained and irritated much less;
  • Higher units help. If the script is written appropriately, it’ll be usable on completely different platforms and units;
  • Higher protection. Lastly, there is a chance to extend testing protection by checking even the smallest ingredient of the software program.


  • Programming abilities are a should. Writing scripts requires sure abilities; subsequently it’s not all the time simple to search out an professional, and his providers would value extra;
  • No person suggestions. The written check fulfills the set situation and is unable to let you know about its impressions, to offer high-quality suggestions;
  • Greater value. Automated testing instruments additionally value some cash, which barely will increase the challenge worth;
  • The issue of UI/UX testing. As we’ve already defined, it’s troublesome to automate the method of testing of software program interfaces, together with their design, usability, and so forth.
  • Imperfect reliability. Though human errors will not happen as a result of automation, different issues may occur, say, brought on by the load on the check machine;
  • No human view of issues. There’re errors within the work of programs that solely people would have the ability to acknowledge;
  • Utilization restrictions. Autotests are aimed toward checking predetermined system options and will not reveal something outdoors the plan.
