Difference Between Manual and Automated Testing

Difference Between Manual and Automated Testing

Software testing is the process of checking and assessing whether a software product or application does what it is designed to do. It is a huge sector, but it may be divided into two categories: manual and automated testing. Both methods of testing have advantages and limitations. In this tutorial, we’ll cover all you need to know about manual and automated testing. Read on to find out!

What is Manual Testing?

A Quality Assurance Analyst performs manual testing. In this case, the tester analyses all of the critical features of the offered application or software.

During this method, software testers run test cases and generate test reports without the use of automated software testing tools. It is a traditional way of testing that aids in the discovery of defects in software systems.

What is Automation Testing?

Automated Software Testing involves testers writing code and test scripts to automate test execution. Test scripts are generated and validated using appropriate automation technologies. The goal is to complete test execution in a shorter amount of time. This sort of testing is based on pre-scripted tests that run separately to compare real and predicted outcomes.

This lets the tester determine whether or not an application runs as planned. Automated testing allows you to run repeated jobs and regression tests without the involvement of a manual tester.

Manual Testing Advantages and Disadvantages 

  • It is affordable because you don’t have to pay for automation tools and processes.
  • Receive quick and accurate visual feedback.
  • While testing a modification, an automation test would require a script, which could take some time. You might test manually on the go.
  • Human sense always helps the manual element.

Disadvantages of manual testing:

Because it is conducted by a human, this form of testing is less dependable. As a result, it is inherently prone to inaccuracy.

The manual testing process cannot be recorded, making it impossible to reuse.

Certain jobs in this testing approach are difficult to carry out manually, which might require more time during the software testing process.

The pros and disadvantages of automated testing 

Advantages of automated testing

  • The majority of the testing process is automated, resulting in a reduced and efficient process.
  • Automated testing helps uncover more bugs than a human tester.
  • The testing is carried out using software tools, so it works without tiring or lack of sleep, unlike humans in manual testing.
  • The automation process may be simply recorded. This allows the tester to reuse and carry out the same kind of testing processes.
  • Testing coverage can be increased because the automation testing tool never forgets to verify even the most minor unit.
  • It can boost productivity by delivering quick and accurate testing results.
  • Automated testing serves a variety of applications.

Disadvantages of Automated Testing:

  • Without the human factor, it is difficult to gain insight into visual parts of your UI, such as colours, fonts, sizes, contrast, and button sizes.
  • Automation testing tools are relatively expensive, which may raise the overall cost of the testing project.
  • Automation testing tools are not yet perfect. Every automation tool has constraints that reduce the extent of automation.
  • Debugging the script or code is another significant difficulty in automated testing. Test maintenance is expensive.

Key Features Between Manual and Automation Testing 

As the demand for automation grows, it might be difficult to decide between manual and automated testing. attempted to clarify this in the table below. Automation also has problems. As a result, it is critical to first understand them before making any decisions.

Manual Testing Automation Testing 
Manual testing is done manually.Automation testing takes place with the use of tools.
The reliability of manual testing is low.Reliability is more
It is less expensive.It is costly
Because humans are capable of error, accuracy is low.The machine makes a few mistakes.
Manual testing may make it difficult to test the application across multiple operating systems.Automation testing  allows us to simply test the programme on a variety of operating systems.
As it includes human intervention, checking the simplicity of access to the application is beneficial.It includes tools.
Manual testing makes it difficult to carry out all test cases, which has an influence on test coverage.We can meet our test coverage objective with automation testing.
Manual testing requires you to create reports on your own.The tool will generate a report on the execution of each test case. TestNG is the framework that will provide a report for you.You only need to run Automation scripts; they can be run overnight!

When Should You Use Manual Testing?

  • Usability testing is the process to assess how efficient and user-friendly a software or product is for customers. Human observation is the most important component here, hence a manual approach is ideal.
  • Exploratory testing assesses a tester’s knowledge, experience, analytical or logical abilities, and intuition. This test stands out by weak specification documentation and a shorter execution time. In this case, human capabilities are necessary to carry out the testing process.
  • Ad-hoc testing has no set approach. It is an unplanned testing approach in which the tester’s understanding and intuition are the sole decisive variables.

When Should You Use Automated Testing?

  • Load Testing: Automated testing is the most effective technique for carrying out loading testing.
  • Regression Testing: Automated testing is appropriate here due to frequent code changes and the ability to execute regressions on time.
  • Repeated Execution: It is better to automate testing that involves the repeated execution of a task.
  • Performance testing, like repeated execution, necessitates the simulation of thousands of concurrent users. Automation is required.

In conclusion, the choice between manual and automated testing ultimately depends on a variety of factors such as the project scope, timeline, budget, and resource availability. Both manual and automated testing have their own strengths and limitations. Manual testing excels in exploratory testing and usability, while automated testing is ideal for repetitive tasks and regression testing. It is important for teams to weigh the pros and cons of each approach and tailor their testing strategy to the specific needs of each project. By leveraging the right mix of manual and automated testing, organisations can achieve higher productivity, improved software quality, and ultimately, better customer satisfaction.Also the manual testing of software provides a comprehensive understanding of both traditional manual testing methods and modern automation testing techniques. By learning both approaches, students can develop a well-rounded skill set that is highly desirable in the software testing industry. The course equips students with the necessary knowledge and practical experience to excel in software testing roles, and prepares them to adapt to the evolving demands of the industry.
