11 Types of Automation Testing For Your Software With the Best Automation Tools

Most tasks related to software testing are repetitive, time-consuming, and boring for a human. Manual automation testing, with human intervention, is more likely to be affected by human errors. Automation testing comes to the rescue to eliminate such risks and relieve the testers from the burden of performing mundane manual testing tasks.

With the development of AI and machine learning technologies, test automation has become an integral part of software QA. Different applications or software call for different types of automation testing. No matter what kind of automation test you run, an effective tool can generate almost 100% accurate reports for you.

In this article, we’re going to discuss what automation testing is, its benefits, its major types, and the best automation tools. Keep reading to learn more.

You can navigate to the main points from the table of contents below.

What Is Automation Testing?

automation software testing

Automation testing refers to any method that conducts software testing without human participation. You can run tests, gather software testing results, and compare them with expected outcomes. The whole process is known as test automation in software testing.

Manual testing requires humans to sit in front of computers and carefully execute each step of the testing process. This type of mundane task is often associated with significant human errors. Automation testing is more efficient because it keeps the errors to almost zero.

How Test Automation Can Benefit You

The best use cases of test automation are- it automates repetitive tasks and renders more accurate results than manual testing. Moreover, you can run both functional and non-functional testing with the right kind of automation testing tools.

Test automation has a lot more advantages to offer. The following list will help you understand how automation testing can benefit you.

  • A faster and more efficient process
  • Scopes to test more features
  • Saves time and money
  • Offers excellent accuracy
  • Generates more reliable findings
  • Requires fewer people to perform the testing
  • Provides detailed comparative reports
  • Facilitates faster release of the software
  • Performs multiple testing at the same time

11 Types of Automation Testing for Software

Types of Automation Testing

Automation testing is mainly of two types- functional and non-functional. Functional tests deal with the real-world application of a software solution. It determines if an application works properly.

On the contrary, non-functional automation testing tests the performance, usability, and speed, and monitors the efficiency of the software. It determines how well the program works.

All other types of automation testing are based on these two major types. Let’s learn more about the types of automation testing from the below section.

1. Unit Testing

Unit testing is the initial step of the automation testing process. It ensures that the application runs hand in hand with all integrated tools. Each application comes with multiple components that are supposed to work perfectly as an individual unit. Unit testing deals with those components as isolated units and tests their functionality.

Upon successful testing, these small units are integrated into the application to form the whole. Once all components qualify at this stage, they are assembled together for the next testing step.

2. Integration Tests

Integration Tests

Integration testing focuses on testing different modules and units of the application as a whole. It figures out whether all integrations of the software meet the functional requirements of the solution.

This testing process studies how each integration interacts with the other. You can easily detect any conflicting issues available among multiple modules and extensions of the software.

3. Smoke Tests

Smoke testing is also known as Confidence Testing. It’s called smoke testing because this test ensures that the program is safe to be tested further without involving the risk of catching fire.

Smoke tests determine if the software is stable and functional. The application should be sent back to the development team if it doesn’t qualify in this phase.

4. API Testing

API Testing

API aka application programming interface allows a component of the application to access data and interact with other external components. A successful application needs to have seamless access to all required components. API testing finds out if the APIs are properly synchronized and working fine as they should.

5. Regression Tests

This test makes sure that an application is correctly updated with new features, functionality, or codebase. Whenever any changes are made to a program, regression testing comes into play. Regression testing determines if the new change makes the application perform as it is supposed to.

If the program behaves the same way before or downgrades to a previous version, then it is called regression. Regression tests are relevant whenever there is any change in coding.

6. Keyword-driven Testing

Keyword-driven Testing

Keyword-driven testing focuses on associating a specific keyword or set of keywords with a specific set of actions. It determines if the intended action gets triggered when a keyword is used. Keyword-driven testing is popular because it is flexible, reusable, and easy to use for even people with less technical knowledge.

7. Data-driven Testing

Usually, each test case runs on the basis of a set of data stored separately in a table or spreadsheet. Developing a new set of data every time is a waste of time and resources. Data-driven testing implies the use of the same data for multiple test cases. It eases this process by facilitating the reusability of code.

8. Performance Tests

Performance Tests

Performance testing is conducted once the development process is done. It involves determining the software’s stability, speed, responsiveness, and functionality under a heavy workload. It focuses on finding out the bugs and hurdles that hamper the performance.

Performance testing helps developers understand how well their product works. The product goes back to the development process if any issues get detected throughout the testing process. Then they can troubleshoot to figure out a problem and find its solution. Thus, a product becomes marketable to its target users.

9. User Interface Tests

Once all the above testing is complete, it turns to finally check the user experience. User experience depends on the functionality, usability, and aesthetic quality of the user interface. User interface testing involves testing these things on behalf of the end-users of the application. The aim of this testing process is to maintain an optimal user experience for all users.

10. Security Tests

Security Tests

As the name suggests, security testing involves everything related to the vulnerability of the application. It finds out if the program is susceptible to security threats. It focuses on finding the weaknesses and helps developers remove the exploitability to build a better application.

11. Acceptance Tests

The aim of building a product is to cater to the needs of its end users. Acceptance tests work with this section of the development process. It tries to predict how the end-users may react to the release of the application. A high acceptance level means the program is likely to gain popularity among the users.

Choose a Framework to Manage the Automation Testing 

Choose a Framework to Manage the Automation Testing 

You don’t need to operate all kinds of automation testing for your application. Select only those you need. Once you can identify the right type of automation testing for your needs, the next phase is choosing a framework to manage the automation The major types of automation testing frameworks are as follows.

Linear framework

This is the simplest approach and works best for a comparatively inexperienced and small team. The linear framework is also called the Record and Playback model.

You need to write simple test scripts to run each test case. This type of framework used in software automation testing doesn’t involve any sequential steps or modularity in its mechanism.

Modular based framework

The modular framework fragments the test scripts into small, individual modules. It allows the testers to create multiple test cases and test the independent modules efficiently.

The modular-based framework is very effective but it requires a great deal of planning and background work. It’s an ideal approach for testers who have significant experience in using automation testing tools.

Library architecture

This is a more advanced and larger version of the modular-based framework, but there are a few differences. Under this system, the tasks are put together in the larger test script in a way that meets their goals. Tasks with similar objectives fall into the same group.

These functions are kept in a library for further reference. The testers can quickly access this data whenever needed. This is a flexible framework. However, you initially devote a significant amount of time to organizing the library.
