Types of Automation Testing | A Comprehensive Guide

Automation testing is a technique in which testers leverage automated software tools for executing test cases. These tests typically include operations that are repetitive in both their nature and outcome. And you have to decide among many different types of automation testing for business.

What is Automation Testing?

Automation testing refers to the use of tools and test scripts to verify software quality. There is no human intervention in running the test cases or reporting the results. Automating the test suite helps in saving the time and effort required in performing repetitive and resource-heavy tasks that are difficult to perform manually. In this blog post, let’s explore the types of Automation testing.

Types of Automation Testing

Automation testing has multiple types as per different categories. Here we are going to discuss three types of automation testing: based on types, phases, and tests. It might sound confusing right now, but when you read about them, you will understand the differences and why they are categorized like such.

Types of Automation Testing Based on the Type of Testing

Automation of Functional Tests

Functional tests check the logic behind the working of an application. And automating these functional tests includes writing scripts and running them using a suitable tool like Testsigma to verify that the application is working per user expectations.

Automation of Non-Functional Tests

Non-functional aspects of an application include everything else that does not come under functional. Anything that is not related to the logic of how the product is working is non-functional. And it also includes creating and executing test scripts using automation tools.

Types of Automation Testing Based on the Phase of Testing

Automation of Unit Tests

Unit test is a type of testing developers run to check the code of the application. Coders can easily write unit tests and automate them to check the program in the development phase.

Automation of UI Tests

UI tests refer to checking the look and feel of the application. It includes validating the business logic and functionality of the product, but only after the complete development is over.

Automation of API Tests

Testers run API tests during the integration phase to check if different nodules/programs of the system are communicating properly. These tests verify the logic as per the request and response of programs that are running the application.

Types of Automation Testing as Per Tests

Let’s discuss several types of automation testing as per tests.

  • Regression tests: They are ideal for automation testing because of their repetitive nature and huge test suite size.
  • Unit tests: The smallest units of code are tested using automation, during the early development stages.
  • Integration tests: They help to certify the seamless interaction between modules and are really critical for any software.
  • Smoke tests: Checks major functionalities of the software are working when an initial new build is deployed.
  • Data-driven tests: Huge data inputs, outputs, and results are easily managed through automation testing, which would otherwise incur enormous manual time and effort.
  • Keyword-driven tests: They are popular today, because of the flexibility, reusability, and clarity keyword-driven tests provide.
  • Performance tests: These tests help test the speed, responsiveness, and stability of the application under test, and most can be performed only with help of an automation tool.

Automation Testing Frameworks

An automation testing framework is a platform that integrates various hardware, software, and tools that enable streamlined design and development of test scripts. With efficient test scripts, testers are able to perform an analysis of the detected bugs of the AUT.

QA engineers effectively leverage automation testing frameworks to find objects and sort them so that they may be reused in test scripts, perform the desired fix on the identified objects, and ensure the objects deliver the desired results.

Linear Frameworks

The linear framework is record and playback driven, which is always achieved linearly. It is more commonly named the record and playback model. Typically, test scripts are created and executed individually in this scripting-driven framework. The automation scripting takes place incrementally, where new interactions are added to the automation tests simultaneously.

Modular Frameworks

Test scripts are developed based on modules or clusters in a modular automation framework. These are formed by dividing the entire software or app into smaller, self-sufficient blocks. Thus, individual test scripts belonging to a particular module or group are created. These scripts belonging to these isolated modules can be integrated and driven by a master driver script to perform integration testing among the modules. All these are achieved with the help of shared function libraries used while developing modules’ scripts. This automation testing framework adheres to the concept of abstraction, wherein test data is added to the test scripts. Test scripts need to be directly updated if there is a need to test with a different combination of test data. The smaller modules in the framework hierarchically communicate with each other to form a large script capable of testing an entire scenario.

Library Architecture Frameworks

The library architecture framework is similar to the modular framework but provides more benefits. Rather than segregating the AUT into different scripts, identical tasks within the script are combined by function. These functions are placed in a library and are called upon by the test scripts when required. Similar to the case of the modular framework, utilizing library architecture enables greater modularization, leading to simplified test maintenance and higher scalability. Library architecture is highly scalable due to the availability of a standard function library that multiple test scripts may use.

Advantages of Leveraging Automation Testing Frameworks

Automation testing frameworks are utilized to execute test cases and decide the output coordinated with user requirements. The testing framework application is constantly independent and is straightforward to expand, use, and maintain.

Automation testing frameworks reduce the time and effort required to perform monotonous tests. It helps find the issues early and understand them at the right time. Additionally, advanced testing frameworks allow testers to explore the full potential of automation testing tools and maximize output.

Reduces Manual Efforts

An automated script saves your group time and counteracts disparities between coding guidelines. It is possible to run automated tests anytime, even when the testers are not physically present at the workplace.

Improves App Scalability

Sometimes, certain areas of the software or application may need updates. Automation testing framework expands the capability to incorporate these things without experiencing a confounded methodology.

Enhances App Adaptability

Another important benefit of utilizing an automation framework is its adaptability and modularity for application testing. The framework ensures that a significant task is separated into reasonable parts, which would then be reusable as and when required.

Reduces Cost and Maintenance

Maintenance is the greatest obstacle to effective automation. A well-planned automation framework helps maintain the code in light of common changes like Reporting structure, Test data, Page Objects, etc.

Optimizes Test Reporting

Testers do not have to execute test scripts manually whenever there is a need to initiate automation testing. Also, you don’t need to supervise the test scripts. At last, the test result is achieved without observing it once in a while. This saves time and simultaneously increases test accuracy.

Provides Maximum Testing Coverage

A well-defined automation framework structure enables keeping up a decent scope of testing and offers the best possible scope of testing.

Enables Reusability of Test Cases

Utilizing common library records is not possible in manual testing. By introducing automation software, it is possible to reuse the library records whenever required without creating them every time. If the module is the equivalent, there is no need to create new documents. This saves the need to do a similar task repeatedly and makes the entire procedure proficient.

When Should Test Cases Be Automated?

The types of test cases that have plenty of complex manual scenarios and require a lot of data should be automated. A test case should be automated if –

  1. It will save a significant amount of time.
  2. The tests are being used repeatedly.
  3. The tests are stable.
  4. The tests are not risky and unlikely to change.
  5. The tests are error-prone if done manually.
  6. There are several downtimes between steps.

Best Practices of Automation Testing

Despite the immense benefits offered by automation testing, the process is sometimes difficult to implement and deviates from the expected results. Efficient execution of automation testing needs the right skills, experience, thoughtfulness, creativity, and zeal to create ROI-driven strategies and frameworks.

It is important to know the best practices of automated testing as they enable testers to create maintainable, readable, and simple automated test suites. Here are some of the tried-and-tested automation testing best practices testers should know of:

Design Test Cases Beforehand

It is recommended to create test cases and scenarios before automating the tests. A good test design helps identify defects as automated tests execute these test designs. The risk involved in moving directly to automation is that you’re only making the script work. In most cases, only the happy flow scenarios are automated. Instead, testers should think of other possible scenarios that may require testing.

Remove the Uncertainties

One of the critical points of adopting automated testing is the ability to provide regular and expected results. If the success of an automated test is not consistent throughout, meaning the test passes once but fails in another run, it may not be determined the cause of app failure. In case of test case failures, testers must analyze the results to understand the cause of failure and make the necessary fixes.

Validate the Automated Test Cases

Outdated tests do not check for essential verifications. Lack of test case validation leads to testers jumping to automation directly without spending enough time on planning and designing good test cases. Always review the test cases for validity and sanity and make sure the tests are up to date.

Prevent Automating Unstable Functionalities

If automation testing begins while a new app feature is being developed, the tests may need to be updated alongside feature updates. It can be challenging to update the test case with every feature update. Therefore, automating only stable features or less subject to change is recommended.

Keep Realistic Expectations

In an ideal scenario, automation testing aims to reduce the overall time required to test an application or software so that exploratory testing may occur. Results from automated testing assure the teams that the app will perform seamlessly, even if there are any recent updates. However, testers should not expect automation testing to deliver a lot of errors as the number of bugs reported in automation testing will be less than the bugs reported in manual testing. Don’t expect automation to find lots of bugs. The number of bugs found by automation is always much less than in manual and exploratory testing.

Understand the Context

Automated tests may be run at any layer, i.e., Unit, API, Service, or GUI. Each application layer provides a different aspect for testing. Unit tests are performed to verify there are no bugs at the class level. API or integration testing is performed to achieve functions and classes that may be integrated to work together and may pass data from within classes. GUI testing ensures the user flows and journeys are seamless and as per the business expectations. If the tester wants to test the app functionality, the testing should be performed at lower layers rather than UI. UI tests should primarily focus on ensuring the application or software delivers according to the predefined use cases.

Do Not Aim for 100% Automation

Complete test coverage is impossible since there can be millions of combinations. Creating a reliable automated script takes a considerable amount of time and effort, and it is not practical for testers to automate all the tests. Rather than automating everything, the focus should be on adopting a risk-based approach so that all possible candidates for automation may be identified. Automating the most critical business scenarios is recommended to achieve the full benefits of automation. Also, automating some testing scenarios takes up additional costs and is difficult to maintain since it relies on downstream system checking. The best solution here is to prefer manual testing for such cases.


One cannot overstate the benefits of automation testing. Given the customer demand for new features every few weeks, organizations must incorporate automation testing. Since a terrible user experience will almost certainly get any application uninstalled and downvoted by customers, automation testing plays a critical role in ensuring the desired customer experience. Without it, developing software that appeals to users becomes significantly more difficult.
