Having a well-defined testing process helps in the following ways, directly and indirectly: Gives enough time to iterate the test execution in manual and automated mode All test artifacts are created and captured along with a clear Requirements Traceability Matrix Scheduling and utilization of testing resources, both in terms of people and environments, becomes effective Defect isolation, reporting, and reproducing become easier The feedback cycle of identifying and addressing a bug is small and quick Test coverage across multiple testing verticals becomes clear and indicates the quality of the software; it includes functional testing, black-box testing, smoke testing, integration testing, regression testing , performance testing, and more The strategy of Test data creation and refresh is concise, clear, and repeatable Once a test process is in place, it is easier and simpler to automate the execution of the tests and reduce the manual interventions in the test cycle.
Test Execution Test execution takes the maximum amount of time in the entire test process. The automation of testing includes the following aspects of the test process: Test data preparation: Using scripts created automatically by tools like Katalon Studio, or written in SQL, Python, Shell, or other similar languages Test cases execution: Using tools such as Katalon Studio, Katalon TestOps, Selenium, or others Test results verification: Using tools like Katalon Studio and Katalon TestOps, or scripts such as Groovy, Ruby, Python, and others Test results visualization: Using advanced reports in Katalon TestOps, JavaScript-based visualization toolkits, or HTML5 based reporting toolkits In the case of automated testing, there is an additional step of preparing the scripts for test cases using a tool or programming language.
Comparisons Whenever automated and manual testing are compared, the following factors are considered; however, automated testing is better on all of these fronts: The accuracy of the execution and results The velocity of execution of the test cases The repetitiveness of the execution steps Cases for Automated Testing The automation of testing is useful in modern-day delivery, both , for quality and velocity.
Automated testing is worth the effort in order to save the time and cost in most of the cases, such as those listed below: Agile development teams require continuous feedback on the quality of their daily deliverables and use them for performing nightly builds.
It includes unit testing, system testing, integration testing, and regression testing of the build. Test results are shared immediately with the development team to address the issues found. At the end of a sprint or a release cycle , the release candidate needs to undergo various types of tests. Having automation ensures that multiple rounds can be run simultaneously or back-to-back to capture the results.
This ensures complete coverage of new functionality, easy regression, configuration verification, and more. Another good case for automation is when there are multiple configuration options available in the software and each needs to be tested. Although the test cases remain the same, the test results may change due to changes in the environmental and software configuration. Running the same test cases manually is time-consuming as well as error-prone.
When concurrency, load, and endurance need to be tested for software, it is best to use automated testing. Performing the same thing manually would require several people to perform the same activity over a long period of time. It is a waste of time, resources, and money.
Automated test cases can be run in parallel from the same machine and produce the same output. Automation of the security tests against threats and attacks is very important to prevent security attacks, DDoS attacks, malicious code injections, brute force attacks, vulnerabilities, cross-site scripting, script injections, impersonation attacks, and more. Quite a few of these attacks cannot be simulated manually and always require automation.
Cases for Manual Testing While test automation is very important for a project, manual testing holds its place in the entire mix. The initial rounds of testing done during the verification phase of the first release candidate are done manually. During this phase, the process of testing and the efficacy of the release candidate is established.
Only after the initial manual testing is completed successfully, can the automated test cases be executed confidently. During the support phase of software, multiple releases of the software are made. While all forms of repetitive testing are performed using automation, there are cases where the software may encounter a P1 bug and require an immediate quick fix.
In such cases, while the regression is performed using automation, the fix of the P1 bugs must be tested manually to ensure completeness. Software testing is a vast domain with the everlasting combination of manual and automated approaches. Manual testing suggested by its name requires executing test cases without the use of additional tools. Automated testing, by contrast, involves script writing, the use of tools and software.
The choice between the two depends on the project requirements, complexity, budget, timeline, etc. Sometimes the right choice of a testing method may help to accomplish the goal better than another. Yet there are cases when an effective combination of manual and automation is the only way to release successfully.
Such monitoring may become one of the best ways to measure the level of software effectiveness and convenience.
QA engineers automate the tests using dedicated tools to run predefined tests and actions written in the test script. Although the key objectives are the same, automated tests show their effectiveness in a bit different areas of software QA. A QA specialist, who performs manual testing, has to be attentive, innovative, resourceful.
Some people may think that because of technological improvement the manual testing era is over, but in reality, this classic method has become vital for software development. Our team of automation QA engineers points out the following advantages their work brings to the project growth:.
The team of automated QA engineers completes a test checklist following manual test cases. When QA specialists adopt multiple benefits and take into account drawbacks of these approaches, they conduct a complex, professional software quality assurance. Robust automation brings about efficiency in the whole testing process, while manual testing remains less costly and more helpful checking user interface.
There is no universal way of testing; each project requires a unique approach. With Automated Software Testing you remove that very quickly. You get to rely on accurate coding that eventually saves you plenty of time. Which is the better option? It all depends on what you need to do. Automated Testing is a very good idea if you need to perform time-consuming, repetitive tasks, functional testing, or load testing, even GUI testing.
Manual testing is better for small or short term projects at the beginning of the development phase, when testing the UI or for physical products.
Both options are great, you just have to learn when to use them for the best outcome!
