When you decide to automate the software testing process, it is necessary to know that not every phase of the application testing can be automated. By type of automation tests, we mean defining the types of test suites that can be automated.
It often happens with testers when they confuse this topic with types of automation frameworks, but it is entirely different than that. Automation is performed on the basis of tests included in a testing process. Here, we will discuss the types of tests that you can automate easily.
1. Automated Unit Tests:
Unit testing is usually conducted by developers, which involves small units or components of a web app. These tests are written to test the code level, find bugs in the functions, routines, and methods. In some organizations, automated unit testing is performed by the developers, whereas, some enterprises prefer to hire specialized test automation resources to execute the tests. Testers write unit tests to break the production code so that they can test the production code in multiple instances. With automated unit tests, it becomes easier to verify the functionality of every component of a web app. And if the unit test fails, it means that the code being pushed to the production environment is faulty. There are numerous automated unit testing frameworks to help developers deliver better software. Some of the renowned ones are NUnit, Junit, Unit, js, QUnit, etc. Even Microsoft provides its own unit testing framework known as MSTest to help you perform Selenium automation testing with C#.
2. API Automation Testing:
An API (Application Programming Interface) helps testers understand the interface of the application more clearly. Nowadays, the API testing of web apps has become more popular among enterprises. In API testing, the business layer of the application is validated by verifying the request-response combinations for various APIs that are included in the application. However, in API testing, the graphical user interface of the app is not included. With automated API testing, the functionality, compliance, and security issues are tested, and if you are testing a web app, then the security of Request and Response is also examined. For automated API testing, you can use LambdaTest that is available in both free and paid versions.
3. GUI Automation Testing:
Automated testing of the graphical user interface is the most challenging task of the testing process because it includes user interface testing of the app. Why it is difficult because the GUI of web apps often keep changing. But, GUI testing is also the most crucial part of the testing process, as it helps users do what they are willing to do on your web app. GUI automation testing impersonates the same actions that users perform with their mouse and keyboard on the user interface. So, chances of finding bugs in GUI in early stages is feasible, and it can also be used in other testing scenarios like regression tests or filling up forms that often take longer. There are multiple GUI testing tools available in the market, such as Selenium, Microsoft Coded UI, etc. Apart from these automated testing, there are some other tests as well that can be automated, such as:
- Performance tests and quality control
- Regression tests
- Integration tests
- UI tests and Smoke tests
- Security tests and Acceptance tests
- Cross-browser compatibility testing
Misconceptions Around Automated Testing
Since the inception of automation testing, many misconceptions are revolving around it that make enterprises not to use it. Below we have tried to clear some of the misconceptions.
1. Automation Will Replace Manual Testers:
The biggest misconception that is making testers worried is that automation will replace manual testers, but this is completely untrue. Automation testing helps testers to improve their testing process in a better way, it will never replace humans because a little human intervention is always required to run automated tests. The benefit of using automation testing is that it helps you test repeated, long, and boring tests quickly while saving time and energy, so that you can focus on other test scenarios and functionality of the web app. Also, tools used in automation testing don’t start testing the web app automatically; a team of testers is always required to start the tool.
2. You Can Automate Everything With Automation:
Most people believe that they can automate all their test cases, but if this is true, then why do you need manual testers? So, this misconception is also false. The fact is you can never automate 100% of your test cases because an application can never be thoroughly tested. There are always some scenarios that testers often miss while testing a web app. And if the app is reviewed carefully even after testing. You will find one or two bugs in it. Also, some parts of a web app are easier to test with manual testing rather than automation testing, so 100% automation testing doesn’t make sense. For example, if you are willing to test CAPTCHA scenarios, Code reading scenarios, Performance testing, then it is recommended to use manual approaches rather than using automation testing.
3. Automation Testing Is Easy:
Do you really think automation testing is easier? Let me tell you, automated testing is one of the hardest parts of the software development life cycle. Even if you’re a professional at automated testing, you would never find it easy to automate the testing process of a software project. Though many automation testing tools prompt automation as one of the easiest things, it is to gain the user’s attention only. The main features of these types of tools are either automating the capture and replay manual test cases. If you ask any organization about how many test cases they actually automate, you will get to know that only 20-30% test cases are automated. This happens because setting up an automation testing environment requires a lot of time and effort, as well as you will have to stay up-to-date with the latest system changes. Automation testing might be easier for regression testing, but it is not reliable for every test scenario with new scripts.
4. Automated Testing Is Too Costly:
Many believe that automated testing requires higher expenses. Well, the upfront costs of automation testing can be higher, but as an organization, you should consider this as a long-term investment. It is true that setting up an automation testing environment and buying an automation tool does require a bit of investment. But, once the environment is set up, you don’t have to invest much into it. In the next few years, the internal investment will provide you with a strong ROI. So, before implementing automation testing for your web app, prefer analyzing the ROI; it will help you determine the benefits of automation testing after investing a little amount.
5. Only Recording and Playback Are Involved in Automation:
Most automation testing tools say that you just need to record and playback your testing steps, and the test cases will be automated. That’s the biggest lie testers hear. Automation is not just about recording and playback; it is much more than that. In fact, it is everything that is included in manual testing. And to be honest, professional automation engineers prefer not to use recording and playback features. In general, the recording and playback feature is only used to analyze how the tool is generating a script for your testing steps. Once testers get to know the scripting, they use this scripting for creating automated tests. Also, you should have programming experience if you want to perform automation testing, even if you don’t know how to program, you can quickly learn it with practice. Individuals from non-technical backgrounds have also gained a little programming experience and now working as professional automation engineers. So, if you want to be an amazing automation tester, then don’t run from programming. Apart from the above points, there are some other misconceptions as well that you will find floating on forum comments, such as you only require unit test automation, it is for regression testing only, it requires a vast team of automation engineers, etc. But, when you will start using automation, you will realize none of them is true. They are just hoax created by people who never used automation.
