Key Considerations of Application Testing: Automated Testing Vs Manual Testing

In general, every project has three essential aspects to consider i.e cost, time and quality. The major goal of any project is to get a high-quality at the end at the affordable cost within a reasonable time to complete the project.

Directly or Indirectly the quality is measured ultimately by testing the product. Also, the testing helps to know, the expectations and reality gaps among the developer to the client. Within the current article, we are going to pin-point 2 major kinds of testing as follows.

  1. Manual Testing 
  2. Automated Testing

We all know, Testing is the fundamental element of any project. But most of the people are not aware of what to choose and when to choose among manual or either automated testing. It’s very important to know the difference between manual testing and automated testing so that it helps to optimize the cost and time of the project.

ROI of testing

It was a well-known fact that both of them have their own benefits and disadvantages. If we consider Manual testing, the tester has to sit in front of the screen and go through each module. In other contrast, Automated testing is a much more powerful for tester as the test cases are performed automatically by using automated tool/software. Basing on several factors like budget, timeline, and human resource….You could choose the right type of testing to archive your goals. Let’s look inside how we can consider these…

What is Automated Testing?


Automated testing is a process that makes use of automation testing tools, scripts and software to perform pre-scripted tests on applications, then compares the test results to the expected levels and report it to the testers. You can perform test automation by writing scripts with codeless tool automation tool or with selenium. These automation testing tools also have the record and playback features which help you to record all your testing activities. By performing the repeated predefined actions the results will be compared. If the output and the expected results same, your product is working well as it supposed to do work. However, all automated testing requires some manual testing at first to create initial testing scripts.

What are the types of Automated Testing?

  • Data Driven Testing:  For this testing, the same functionalities needed to be validated with lots of different inputs and large datasets (for example login, sign up, search, etc).
  • Load testing: This helps to determine a system’s performance in real-time while loading the application. It will find how the system behaves when multiple users access it simultaneously.
  • Performance Testing: Performance testing helps to get the speed, scalability and stability of the application. The goal is to reduce any performance bottlenecks. This requires simulation of thousands of simultaneous users.
  • Regression Testing: Because of frequent code changes and therefore the ability to run the regressions in a timely manner.
  • Repeated Execution: The repeated execution of a task is the best-automated testing.
Advantages of Automated Testing:
  • In automated testing, most of the process is automatic which makes it into an efficient and fast testing process.
  • The level of productivity is improved with this process and is quick to provide accurate testing results.
  • The automated testing tactics are supported by a majority of applications.
  • With automated testing, you can spot more bugs
  • The user can record the process of automated testing, which further allows it to be reused and executed.
Disadvantages of Automated Testing:
  • As there is no human element in automated testing, it becomes difficult to get appropriate insight into the visual aspects including the fonts, colours, and other user interface elements.
  • The advanced tools required for automation testing can be quite pricey.
  • There are flaws with every automated testing tool like the test maintenance cost being high.
Summarised points of Automated testing:
  • Automated testing is much faster due to using the software.
  • Less UI feedback.
  • It could be costly at the starting stage, but in the long-term, it will reduce the cost.
  • High accuracy result.
  • More reliable.
  • Programming is required.
  • Regression testing is easy due to using tools.
  • Once the test requirements are made, it requires the fewer tester to execute test cases.

What is Manual Testing?

Manual testing is actually a self-explanatorytesting of a web or mobile application is done manually by human action which is intended to find out the defects or bugs in a software program by going on a device to evaluate numerous components including design, functionality, and performance by clicking through multiple elements or units of a web application without support from a tool or script to make sure that they are working as they are supposed to work. Everything will be done manually so it is time-consuming and laborious.

What are the types of Manual Testing?

  • Exploratory Testing: In this type of testing the tester’s knowledge, experience, analytics/logical skills, creativity, and intuition is the most essential elements. The test will be characterized by poorly written specification documentation, and/or a short time for execution. This approach requires the least planning and most test execution.
  • Usability Testing: Using this approach we will know how user-friendly, efficient, or convenient the product is for the end users? The goal of this testing is human observation and satisfaction.
  • Ad-hoc testing: The testing is performed without any plan or documentation. The output is totally dependent on the skill and knowledge of the tester.

In order to know when to use each type of testing, you need to understand the advantages and disadvantages of each testing. Using the right method at the right time will save your time and will give the best results. So let’s go through advantages and disadvantages of Manual and Automated testing.

Advantages of Manual testing:
  • In comparison to automated testing, manual testing is less extensive and cost-efficient.
  • Because of the involvement of the human element, we get accurate user interface feedback in testing.
  • The user doesn’t need to change the entire code, in order to make small quick fixes in the app.
  • With manual testing, we can get the exact replication of the real user experience on the web and mobile apps.
  • The manual testing approach is able to handle difficult use case situations better than the automated testing.
Disadvantages of Manual Testing:
  • In manual testing, the choice of recording the testing process is not available and that makes it less efficient.
  • As manual testing is handled by the humans that’s why changes in errors are higher.
  • Sometimes the tasks seem to be complicated and unrealistic to be performed manually which may even require additional time to be completed.
Summarised points of Manual testing:
  • Manual testing is time-spending because running test cases in everything is done manually.
  • The tester can observe the application during testing, making the user-friendliness better.
  • Less expensive in the short-term.
  • Low accuracy result.
  • Less reliable.
  • Programming is not required
  • Regression testing is time-consuming and laborious.
  • The same amount of time is required to perform the test cases.

Difference Between Automates Testing and Manual Testing


For optimizing the cost and time required for successful completion of a project, you cannot solely depend on the manual testing or automated testing approach. You may need a right combination of both the testings to get the best output for the product.
