Difference between Manual and Automation Testing

Difference between Manual and Automation Testing


Software testing can be defines as task from planning to execution. These software programs help you to easily identify any bugs or errors in the program. If you would take a look at testing tools today more specifically software test tools, that is you would see a lot of them that are automated. This is because having automated software test tools would certainly make the process of software testing much more convenient and faster. The world of technology revolves at a fast pace today.

Manual test tools did have its fair share of responsibilities back in the day, and they did perform very well. However, gone are the days when you can rely on manual tools. Investing in such could even mean the untimely demise of the software development company because they would inevitably be left behind by its competitors who have already joined the worthwhile bandwagon.

You also have to understand that the testing phase of the software could even take longer than the production phase itself. This can be pretty hard on any software engineer if he or she were to use manual test tools because testing takes a lot of time, effort, and resources. Technically, using manual tools would just be a waste of time. Imagine how much time would be wasted when you would have to start from the very beginning whenever you would detect a particular error, defect, or bug in the program. Without automated test tools, this would be the likely scenario, going back to square one or starting from scratch. A month’s worth of manual software testing could be had in just a few weeks’ time when you use automated tools. There would even be times when it would take just a few days or even hours, depending on the nature of the software being developed.

Manual testing:

Manual testing is the process of manually testing software for defects. It requires a tester to play the role of an end user, and use most of all features of the application to ensure correct behavior. To ensure completeness of testing, the tester often follows a written test plan that leads them through a set of important test cases.

Advantages of manual testing :

  • It is used in both big and small projects.
  • The test cases can be added or removed according to the movement of the project.
  • Within a limited cost budget you can finish this testing.
  • Manual testing is better than automated testing in terms of reliability.
  • Tester can execute additional ad-hoc. You will find that more bugs and errors are found with adhoc than the automation.

Disadvantages of manual testing :

  • By using manual testing, you cannot find the size difference of the GUI object and color combination easily.
  • In this type of testing, the real performance and load cannot be determined for a huge number of clients.
  • Manual testing is time consuming.

Automated testing:

Test automation is the use of software to control the execution of tests, the comparison of actual outcomes to predicted outcomes, the setting up of test preconditions, and other test control and test reporting functions. Commonly, test automation involves automating a manual process already in place that uses a formalized testing process.

Advantages of automated testing :

  • Within a short period of time, you can cover all the major test cases.
  • Using tools, you can check all kind of cases like performance and load of the software.
  • It is the best choice for regression testing.
  • Sometimes certain websites requires instantaneous assessment, and this testing is the best choice during this time.
  • This testing can be executed on different operating platforms within same time.
  • This kind of testing is used as easy tools in the case of volume testing.
  • Within short period, you can obtain test results of many test cases.

Disadvantages of automated testing :

  • This test will use a longer time, as it requires test cases to be resolved in to scripts.
  • When you compare it to manual testing, this testing is expensive.
  • Not all tools support all languages, as there is much software for different language testing.
  • This kind of testing is not able to detect color related issues.
  • As it cannot read tags, hence automated testing is not able to recognize any kind of heading tags that is missing.
  • This test cannot identify the descriptive attributes.

To find out whether the website is logical or functional in case the browsers are not supporting the scripts and style sheets or even if the user disable these it cannot be identified by automated testing.
