Difference between manual testing and automation testing

※ Download: Difference between manual testing and automation testing Manual testing, on the other hand, allows the developing program to be used as it would be upon launch. The results produced using automated testing has high quality as they are more accurate. In comparison, manual testing has to be done sequentially, and so only one test can be run at a time. Fewer errors The automated tests are less susceptible to errors compared to humans. Read More: What is the difference between automation testing and manual testing? For example, assessing whether an icon is suitably meaningful and positioned nicely is a matter for people not computers, because the computer doesn't care but the user does. Every automation tool has their limitations which reduces the scope of automation. Manual Testing: - If there is any change to the software, you have to run the tests again by hand. While neither of these options are technically better or worse than the other, the size, budget and time allowance of a project will certainly be factors that affect which method will work best in your testing procedure. Manual Testing Manual testing is essentially self-explanatory — testing of a web application is done manually, by human action. This means that someone actually goes 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. Sometimes, people will interchange the terms or with manual testing, as well. Advantages The method of manual testing is inherently valuable to consumer-facing websites because the tester is able to have the full user experience, making it easier to assess visual components such as text size and layout as well as UI. It can also be a boring, time consuming and tedious task for developers to continually perform manual tests every time they update a code, rather than spending their time actually improving the code itself. Manual Testing v Automated Testing for CI Automated Testing Automated testing uses the assistance of tools, scripts, and software to perform test cases by repeating pre-defined actions. You can perform test automation by writing scripts with or through a codeless tool automation tool. All automated testing, however, requires some manual testing at first to create initial testing scripts. This is because automation allows multiple tests to be , since the test cases can be distributed across different machines. In comparison, manual testing has to be done sequentially, and so only one test can be run at a time. In this way, the accuracy of automated testing makes it ideal for finding bugs when running tests repeatedly over a long time period or running multiple tests on different browsers. Additionally, automated testing is preferred for large projects that require regression, load, and performance testing or any repeated execution. Specifically, developers that use an Agile methodology depend on automated testing to be able to retest scripts as they continually change code because manually testing every time a small fix was made would be exceptionally time-consuming. Disadvantages The downfall of automated testing is that, unlike manual testing, there is little human observation involved. While automated testing is more efficient in many ways, developers will sometimes find that they need to execute manual testing in order to add a human element and meet specific consumer needs. Often people will attribute automated testing because it requires a greater investment in tools. However, if your project calls for automated testing, this investment will most likely pay for itself and be more cost-effective over time. Tools such as CrossBrowserTesting offer solutions and features that complement manual and automated testing alike. These value-add features including , Selenium, , and all contribute to a well-rounded project execution. However, the success of your testing process will first depend on your ability to measure which testing method is best for your project.

Alex McPeak is a Content Marketing Specialist for CrossBrowserTesting and is always looking to provide insights in testing, development, and design for the software community, appearing in outlets such as Abstracta, DZone, and Ministry of Testing. She's especially interested in writing about the latest innovations in technology and is forever TeamiPhone. It is considered less reliable because of human error. Each page of your app or site could have several user stories. In this way, the accuracy of automated testing makes it ideal for finding bugs when running tests repeatedly over a long time period or running multiple tests on different browsers.

We need the human skills to execute the testing process in this scenario. Automation Testing: The method takes automation tool support to execute the test cases is known as Automation Testing. But anyways many thanks for sharing your experience Sir. Reviewing your test suite frequently to add tests worth automated and remove unsuitable ones.
