Software testing has become an essential part of software development, where reliability, quality and safety of a program are the core pillars of good output. The more programs integrate into our daily life the greater is the demand for quality assurance. Hence, quality assurance is the process of ensuring customers that the developed app has no defects or other issues. Unfortunately, there is no 100% certainty some errors will be spotted out when the testing is done with the help of a human, so there are automated testing tools to do the job and satisfy the customer. In order to ensure an application works accurately, QA engineers perform either manual or automation testing. Both manual testing and automation testing carry out the same mission but require different approaches towards testing itself. So, the question pops up – what is manual testing and automation testing, where and when is it used?
Manual testing is a process of software testing that spots various defects and errors during a test suite. It is performed by a QA engineer, who runs test cases and analyzes the functionality of a program from the user’s perspective to make sure there are no bugs or unexpected program failures. Moreover, testers create test reports manually. During this kind of testing, QA engineers use no particular software automation tools.
Before applying to manual testing, it is necessary to understand how to do manual testing. Thus, it is important to analyze the requirements or software documentation, create a specific test plan, write test cases based on documentation requirements, review these test cases, execute them, report bugs (if there are some!) and re-run test cases to exclude bug repetitions. Generally, there are four stages of manual testing:
Based on these stages manual testing is divided into three types:
Some of the tools used in manual testing are Google Apps (Google Drive, Google Spreadsheets, etc.), JIRA and plugins (e.g. Zephyr), Test Link and Browser Dev Tools.
Usually, manual testing is carried out to find critical errors in the newly-developed apps before automating the testing process of these apps. Of course, everything, which is done manually, requires extra time, cost and effort and becomes boring when frequently repeated. It is not effective in the long run if to take ROI into account. In addition, not every app can be tested manually if multiple troubleshooting and test cases are needed. That’s when to automate testing.
Automation testing is the process of software testing with the help of software tools that is faster, more accurate and efficient. Here, test scripts are done by a computer that runs them on its own and at any time – even during the nights! Thus, QA engineers might concentrate on tasks that are more important at the moment and enjoy the testing process. For example, it is impossible to perform 10,000 checks of Facebook logins and activities on the platform at once manually. However, automation testing can do the job. If test scripts are automated, there is no need for additional manual check-ups. What is more, due to automation testing the ROI improves.
Before implementing automation testing and finding methods how to automate test cases it is also necessary to make up your mind what test cases should be automated, perform early and frequent testing to ensure better results, choose the right tool for automated testing of the app, make a smart division of the automated testing tendency, create test data of excellent quality, and develop automated tests that easily adjust to the UI changes.
So, when to automate tests? Here, the benefit of automation test cases lies in the number of test scripts to be run and repeated. Hence, automation is required when:
Numerous Automation Testing Tools exist and QA engineers use them to perform different kinds of testing activities, e.g. web application testing, API Testing Tools and Performance Testing Tools.
Despite the fact that automation testing decreases manual working hours, it does not substitute manual testing completely. It’s the type of test execution needed that really counts in the choice of a testing method. So, manual testing vs automation testing – what’s the difference?
Return on Investment (ROI) is mostly used by businesses that desire to know their key performance indicator (KPI) and forecast the future profit of the current expenses and contributions. ROI shows statistical data of future successes based on the right business decisions. ROI calculation gives a better understanding of business solutions and whether your business decision-making is successful and brings profit. For example, if you would like to calculate the ROI of the automation process you should take into account:
Based on the given information, the biggest ROI will be achieved when the process is:
Here, your ROI will be 357% in a year, 379% in three years, and 383% in five years. In comparison, if the process is:
Your ROI will be 7% in a year, 15% in three years and 19% in five years, respectively. So, the choice is on you!
At Inoxoft we understand what is best for our clients and plan application test execution thoroughly. Taking full responsibility for a successful app development, our QA team provides the best quality assurance services.
As the performance of an app is affected directly by the choice of the software testing methods, we suggest automation testing as an end-to-end testing because:
Having the knowledge of coding skills and working with automation frameworks and tools, our QA engineers know how to automation test cases and design test scripts. Therefore, the choice of applying Manual testing or Automation testing depends on the final goal you’d like to achieve.
