Do you know the difference between manual and automated testing? You might have come across this terminology while working on a project, or you have heard this in your college subjects. It is quite confusing for someone to know which testing method I should use in my project and how to differentiate between them to know more about testing. Both manual and automated testing are types of testing, and it is very crucial to know the vital differences between them. This guide will help you know everything about manual and automated testing.
What is Manual Testing?
In manual testing, no automation tools are involved, and it is a common way of testing software. In this process, test cases are prepared, executed one at a time, and verified as to whether the application is behaving as expected or not. Lastly, they develop a report on what they have found.
Manual testing, because it is performed entirely by humans, may be more time-consuming and prone to human error. However, at the same time, it adds something impossible to get through automation- human intuition and judgment.
Consider that you are testing a food delivery app. As a manual tester, you will launch the app, make an order, enter a promo code, and observe whether the delivery costs are accurate and, finally, track the order. You will look for bugs, but also the smoothness with which a user will interact with it.
When Should Manual Testing be done?
The manual test is an ideal option when there is no possibility of automation or where automation cannot bring much value. There are key scenarios as follows:
- Exploratory Testing: This is when you wish to test more new and unexplored features without adherence to fixed scripts.
- Usability Testing: when you need to see whether the app is intuitive to use, visually pleasing, and offers a quality user experience.
- Ad-Hoc Testing: It is testing an application in a short time after minor changes or bug fixes are made.
- Visual/GUI Testing: When the visual aspect of presentation, e.g., colours, fonts, layouts of design details across devices and browsers, needs to be checked.
What is Automation Testing
Automation testing is a new-fangled method where we utilize programming tools and scripts to carry out the tests. Instead of a person going through each step individually, a script that was previously prepared executes the process and compares the actual outcomes against the expected outcomes.
This increases the speed and reliability of automation testing, particularly on routine procedures. However, in one way, it involves some manual work in the beginning, that is, the testers have to write and maintain the test scripts.
In this case, imagine that you have a shopping store online with thousands of products. Whenever a new update is issued, you should test to see whether the Add to Cart and the Checkout features continue to work. This would not be possible to do manually each time without taking days. By automating something, you only need to write a script once, then run it whenever you need to do it, which can save a lot of time.
When Should Automation Testing be done?
Automation testing is most useful where speed and repeatability are critical. A few of the important instances are:
- Repetitive Tasks: This is especially the case with regression tests when the same features have to be retested after an update takes place.
- Large-Scale Testing: When it is large, software and manual testing can take too much time.
- Performance Testing: The desire to know how the app will act under intensive load or when you have lots of users.
- Short Time: There are time limits, and not all things can be done by man.
Career Opportunity in Testing
According to the U.S. Bureau of Labor Statistics (BLS), there will be a 17% increment in the demand for software testers in the U.S between 2023 and 2033. The advancement in fields like AI, cloud computing, and cybersecurity raises the demand for a professional and skilled software tester. Companies rely on skilled testers to ensure product reliability.
Career Roles and their progression

Frequently Asked Questions on The Difference Between Manual and Automated Testing
Question 1. Why is manual testing valuable when so much emphasis is being placed on automation?
Answer: Manual testing is valuable because not everything can be automated. Manual testing depicts real-life scenarios for users, and it uncovers usability bugs or UX bugs (UI bugs) that automation tools cannot find. Manual testing is also a good choice for beginners or individuals doing short-term projects, as it is cheaper and more flexible for beginners learning, as well as quickly adapting to facts in their short-term findings, a process that works well with all of the foundational training at View Softnic Academy.
Question 2. If I am new to software testing, should I start with manual or automation testing?
Answer: It is highly recommended that you start with manual testing. Manual testing will allow you to gain better knowledge of software functionality as well as the user viewpoint. The View Softnic courses will steer a beginner through the basics of manual testing first, and in accordance with the deepest understanding of the various manual testing techniques, they subsequently introduce automation tools and automation scripts. By then, you will have a thorough understanding of testing principles and practice them step-by-step without pressure.
Question 3. Does automation testing really find all software bugs?
Answer: Automation testing is an amazing way to find consistent errors in repeated test cases, but it will not catch every bug. Some bugs will require human judgement as they involve complex visual or user-experience issues. That is why View Softnic believes in balance, and the need for training to use automation efficiency with the standard judgement manual testers generally employ, to provide a more thorough overall testing of products.
Question 4. How does learning testing at View Softnic set me up for what I would be expected to do in my career in testing?
Answer: View Softnic Academy provides you with real, hands-on training of manual and automation testing with real tools, based on real-life scenarios. While you are expected to use automated tools, there is a process. Our experts will be teaching you how to create your test cases, manage the execution, and maintain your automated scripts. This is intended to make you job-ready by giving you some of the skills businesses are looking for in a QA professional.
Question 5. Can I go from manual testing to automation testing after I have taken the beginner course?
Answer: Yes, in fact, I can tell you most of the successful testers I know started their careers with manual testing and gradually moved into automation testing by learning systematically. View Softnic will provide a systematic approach to learning manual testing, including automated testing, as well as foundational programming and mastering tools, so you can confidently automate tests as you expand your career.
Question 6. Which is better for beginners – manual or automation?
Answer: It is always better to start with manual testing, where you will learn the foundational core concepts related to testing. Manual testing helps you to understand how to test software manually and how to write test cases efficiently. When you gain enough experience with manual testing, then you should go with automation testing.
Question 7. How long does it take to learn automation testing?
Answer: To begin your learning journey in automation testing, you should first understand the basics of testing concepts and then a programming language (Python, Java, JavaScript). Then you get some exposure to testing tools, like Selenium, JUnit, and Appium.
If you are a beginner, then it may take 1 month to learn a tool, and overall, it would take 3 – 4 months to learn automation testing.
Question 8. Do I need coding to learn automation testing?
Answer: Yes, at least you should have a basic understanding of one of the coding languages, such as Python, Java, or JavaScript. This programming language helps you to write the scripts which is required to perform automation testing. Although there are some tools which is based on low-code or no-code solutions, where you don’t need any programming experience. But if you know a programming language, then it always gives an edge over others, as it helps you with problem-solving skills and also enhances your capabilities as a tester.
