Manual vs Automation Testing - Your Complete Guide!


Software is a broad term used to describe the various kinds of programs that are used to operate various computers and other related devices. It can be called a collection of instructions that empower the user to act together with a computer and its hardware to perform the desired tasks. But a software requires testing to achieve optimal performance levels post-rollout. Here, comes the necessity of manual and automation testing. To know which one is better, you need to know manual testing vs automation testing. 

Without software, most computers would be of no use. Therefore, when a software is developed it is tested carefully to check whether it is is working properly or not. Because unless the software yields the desired results, it is of no use.

A comparison between manual testing vs automation testing will help understand which technique is best suited to chcek a software’s effectiveness.

In this article, we will delve into dwell between manual vs automation testing. You will learn:  -

So, without wasting further time, let’s dive in for an enriched learning experience!

What Is Software Testing ?

Software testing is the activity  that is aimed at evaluating the capability of a program or system and determining that it meets its expected results. Software Testing is a process of executing a program or system  to find errors or mistakes. 

The problem in software testing stems from the complexity of the software; we cannot wholly test a program with mild complexity. Software Testing is something more than just debugging. The purpose of software testing can be quality assurance, reliability estimation or verification and validation.

 Unlike physical systems, most of the defects in software are design errors and not manufacturing defects. Once the software is ready, the design defects remain concealed until activation. Therefore, software testing becomes an integral part of removing any of the bugs that may have appeared.

Why Do We Need Software Testing?

Software testing is broadly dispersed in every phase of the software development cycle. More than 50% of the development time is spent in its testing.

Software testing is needed in software development for the following purposes:

1. For Reliability Estimation - Software reliability has important relations with many aspects of the software, including the structure and the amount of testing it has been subjected to.  Testing can serve as a statistical sampling method to gain failure data for reliability estimation based on an operational profile.

2. To Improve Quality - As computers and software are used in critical applications, the outcome of a bug can be severe. Bugs in critical systems have caused airplane crashes, halted trading on the stock market, and even worse. Bugs can cause  massive disasters. 

Quality means the conformance to the specified design requirement. Being correct, the minimum requirement of quality means performing as required under specified circumstances. Debugging is a narrow view of software testing, and is performed heavily to find out design defects by the programmer.

3. For Verification and Validation - Verification and validation are other vital purposes of software testing. Testers make claims based on interpretations of the testing results. We can also compare the quality of different products under the same specification based on results from the same test. Good software testing provides measures for all relevant factors.

What Is Manual Testing?

Manual Testing is a procedure done to figure out the defects in software that have been developed. In this type of testing, the tester manually checks features of the given application, program and software to ensure a proper functioning  of that application, program or software. 

In Manual Testing, a tester executes the test cases and generate test reports without using automation testing tools. It is performed by an experienced testing professional as a type of preparatory method which and must be completed before the beginning of automation of the various experiments. This method  additionally checks the need for mechanized testing. 

What Are the Advantages of Manual Testing?

Here are a few advantages that you have while you opt for manual testing-

advantages of manual testing

  1. Cost-Effective in Short-Term Scenarios: Buying software automation tools can turn out to be very expensive. With the help of manual testing, you won’t have to invest an insanely huge amount of money on testing.
  2. Bugs Related to User-Handling are Caught More Easily: Automated tests are literally robotic. They fail to act as an actual end-user would. On the other hand, manual testing permits the developing program to be tested and used as it would be used on its launch or final delivery. Any bugs and defects that may pop up as soon as a user handles the given software in a certain way are more likely to be wedged with the help of manual testing.
  3. Manual Testing is Adaptable: In manual testing, you can swiftly test and see the outcomes. Automatic tests take more time to set up and adjust to the change, which doesn’t allow you to test ideas swiftly and conveniently.

Manual Testing Cons

  • Manual testing can be less reliable because of human intervention. Therefore, more prone to mistakes & errors.
  • You will not be able to record the manual testing process. Hence, you can’t use this process again.
  • Through this testing method, certain testing tasks are extremely difficult to perform manually.

What Is Automation Testing?

Before we go into manual testing vs automation testing, let’s first understand the Automation Testing. It is a type of testing performed with the help of an automation tool to write and then execute a tester's test scripts and test cases. The critical purpose of Automation Testing is to lessen the number of test cases to be run by manual testers, but not discarding Manual Testing all in all.

If the software's intended expectations and outcomes align with each other, then it is understood that your project is behaving as it should, and your program is most likely bug-free. If the two are not in accordance, that indicates an issue that needs to be addressed. 

You'll have to take a good look at your code, change it, and continue to run the necessary tests until the actual results align with the expected results.

What Are the Advantages of Automation Testing?

Before you go on picking sides with the type of testing in manual testing vs automation testing  it is better that you take a look at the advantages of automation testing too. 

advantages of automation testing

1. Instantaneous and Cogent: It is true that the initial setup of the testing does take time, but once it is done; there are no delays after that. Everything is as quick as it could be. You will not be required to continuously fill out the same repeated information or remember to run certain particular tests. Everything is taken care of you already.

2. Cost-Effective in the Long Run: While the automation tools can seem to be exorbitant initially, they do end up saving you a good amount of money in the long-term. They surely do a lot more than a human tester can in a given amount of time and additionally they also find defects faster.
