Manual or Automated testing – what to consider for a mid-size project?
Manual and automated testing are both very important in developing a successful website or an application, so it is crucial to make them part of your project from the very start. Software Testing – is an integral part of your project that will save you tons of time and money rather than you just wait till the end and fix it afterwards.
There are two ways of testing your project: automated testing and manual testing. Both types have their pros and cons. In this article, you are going to read about them and think whether you should use the first or the second one, or both.
What is manual testing? It is a tedious procedure. It can be a drag if you are willing to make many further modifications in your app. When testing manually you don’t have any expenses in connection with the use of automation tools, instead you are being charged for someone’s time and efforts. Many results could appear to be more cost-effective if they mostly depend on what you use the testing for.
Mentioned below are the pros and cons of manual testing that can help you figure out how you can benefit from it.
Manual Testing Pros
- Visual Feedback: Automated testing software cannot provide you with suggestions and opinions on how a UI looks and appeals to the human eye as well as an actual person can do.
- Human remarks: You will be getting the exact remarks that you would get from an actual human using your app or website. You will be able to figure out what your users would like or not. Getting feedback like this can grant you a better chance at coming up with the best design and user interface.
- Cost Effective in a Short Term: If your project is about a simple app that has to be tested only once, then manual testing could be cheaper for you because that way you would not have to spend extra money on expensive software or tools.
- On the spot, flexible testing: Testing requires you to make many modifications and test again and again. But if you only have to test just once and make only a simple change, then manual testing is best as it can give you results right on the spot.
Manual Testing Cons
- Less accurate: Manual testing can be accounted for human error. That is why you might have to run the tests several times to get it right. When a script is running a test it is less likely to skip out or miss something.
- Testing fatigue: Developers do not test their own apps because they are too familiar with them and are prone to slip through cracks and miss major points. The same goes with manual testers when they get too familiar with how the app works. Repetitive and tedious tasks can make the testers tired of the same thing over and over again and make them miss out on checking important things.
Automated testing works by comparing the expected results of how a certain program should function with how it actually does. Tests that include series of actions that are predefined in your software are run by automation testers and are observed to see if a system performs as expected. If the elements don’t perform the way that they should have been, it means that you are likely to have a bug in your program. The automation script will point the bugs out so that they can be fixed. Here we have the pros and cons of automated testing to help you figure out if it is a good option for your project:
Automated Testing Pros
- Point out more bugs: Scripts are more accurate than human testers. There is almost no chance of a script missing out a bug or error.
- Efficiency and Speed: Scripts are much faster than human testers so you can get a lot of tests run in a very short period of time.
- Reusability: If you are consistently republishing units and making updates, you don’t have to write an entirely new script each time. The previously written script can simply be reused in your regression testing.
- Keeps you on the same page: With results generated from automated testing it is easier for the team to stay on the same page as compared to the results from manual
Automated Testing Cons
- No human element: Automated testing lacks human element and thus this becomes one of its major cons.
- Less feedback on UI: With the human element you are getting insights on the visual elements of the UI. Things like the text, color contrasts, font size or button placement aren’t recognized by the script as well as an actual person does.
- Cost: The total cost of the tools for automated testing and the up-front time can be costly. But the time saving and reusability factors mostly cover it up.
In conclusion, we have found out that if you have a simple task that doesn’t have many changes to be made in the future, you can go along with manual testing. It is best for such kind of tasks because it provides a very realistic approach to the tests. However, for bigger projects it might be not so helpful. The best choice for complicated projects is automated testing. It is thorough, quick and can be run several times. To add, there are projects which might imply the use of both methods. In that case, you would need a bigger budget for it, but in exchange you will receive the best result possible.
