What is Test Automation, and What are the Types of Automation Testing?

Automation testing is the method of automating software testing. Automation testing is important because it helps ensure that the software's quality meets the business and customers' needs. It can be used for any program, but it's most often used for web applications, desktop applications, and mobile applications.

Automated testing involves creating tests written in a computer language such as Java or C++ (or other), then running those tests on a computer to see if they work as expected. This testing is common practice for software developers because it ensures that all code works as intended before it is released into production.

Why automate?

Test automation helps identify bugs quickly, which saves time and money and makes developers happy. It also allows for better collaboration between developers and testers because it allows them to work together on fixing bugs without relying on one another for information about what went wrong with a particular feature or bug.

As a developer, you can write automated tests much faster than manual scripts that need to be maintained over time as features change or new bugs are discovered.

How does test automation work?

It is the practice of automating tests. It allows you to run automated tests on your applications and check for errors as you develop them. It can be used to improve your quality assurance, increase productivity, and reduce project risk.

There are three main steps involved in automation testing. First, you need RPA for test automation, which involves writing the code that makes up your automated tests against your source code. Then you have to write a script that defines how those tests are run. Finally, you have to ensure all of those scripts are executed by someone who knows how to use them.

Types of automation testing

• Unit Testing 

Unit tests check for errors in a specific unit: a single method, class, or module. They are run against each entity individually and are written specifically to test that entity without side effects on other parts of the system.

• Component Testing

Component tests check for errors in multiple components at once. For example, they can check whether several objects interact correctly when created by other objects. These tests should also be written with side effects in mind so that it doesn't interfere with any future functionality after creating those objects by other means (for example, by calling methods).

• Integration testing

is a process that tests the integration of two or more systems. Integration testing aims to ensure that two or more systems are working correctly and communicating with each other.

Integration testing can be performed at any point in the software development life cycle, but it's typically done after a product has been designed, developed, and documented. Integration testing aims to ensure that your product works as expected when it's implemented in the real world.

• Regression testing

Software testing verifies whether a particular feature or code works as expected. It's typically used to ensure that new features do not break existing functionality and can be done manually or using tools. Regression testing can also detect bugs in existing code, which may have been introduced during your product's life cycle.

• Smoke testing

Smoke testing is verifying a website's functionality before moving on to the next testing phase. Smoke testing involves simulating web activity on a live site or mock-up to check your website's performance under real-world conditions.

You can use a black hat approach to perform smoke tests, in which you try to break your site by injecting malicious code. Or, you could use white hat techniques such as automated tools that crawl through websites and report on their health.

• Functional testing 

It is the process of using a computer to execute software and hardware systems while they are in use. These tests evaluate the system's ability to perform its intended function.

Developers use functional testing to determine whether the software or hardware meets its design requirements and specifications, including any bugs or defects that may have been introduced during development. Functional testing also includes verification that an application will work on the expected platform with all required components installed.

Conclusion

Test automation is a way to improve software quality by automating the testing process. Automation testing is an important aspect of software development. It helps developers find bugs in their code before becoming difficult to fix.
