Automation testing - Types, Frameworks, Steps & Benefits

Automation testing is the practise of testing a software application and other tech products using different techniques with specific automation testing software tools. All this process aims to execute a test case suite and check if the software responds exactly the way it is supposed to.

Different types of automation testing tools, scripts and frameworks are used to perform test cases by repeating pre-defined actions and are run without human intervention.

Meaning of automation testing 

Automation testing uses software tools to automate a series of test tasks that were previously carried out by manual testers.

Just as the name suggests, automated software testing is a method in software testing that uses special software tools to control the execution of tests and then compares actual test results with predicted or expected results.

Instead of a human tester manually testing everything on a site, automated testing automates the process in order to save time while maintaining accuracy related to functionality, performance, and security.

Automation testing ensures that you are able to optimize your productivity without missing important bugs. Furthermore, unlike manual testing, automation testing can check for the functionalities and edge cases for which manual test cases may not have been developed efficiently. 

In contrast, manual testing that is driven by continuous human intervention which compiles insights and test results manually. Check few of the main differences between the both.

Top automation testing types

When choosing what type of test automation to implement, you need to know about the different types of automated testing out there. 

Understanding these differences and what they are good for can help your software development team make the most of test automation.

There are several different types of automated testing available today, most known include;


Unit tests

Unit testing is the first level of testing and sets the foundation for other, more extensive testing types. It involves testing individual components or functions in isolation to ensure they work as expected.

Unit testing is performed during the development phase, hence, it is run during the very first phase of testing. Usually is done manually by developers before hanging the software off to the testers.

Worth to be mentioned that the process of unit testing can also be automated.

Unit tests are essential for building a good application as they help identify bugs early in the development lifecycle while helping developers understand the functionality of each unit in the application. 

Unit tests also make it easy to reuse code, which helps boost the overall productivity of your team.

Integration testing

The focus of integration testing is on verifying whether the modules or subunits of the application are working properly. 

All the individual units of software are taken and then tested all together as a whole in order to guarantee smooth-running performance.

Acceptance testing

Every software has a purpose why it is built and what aims to serve, and acceptance testing is here to make sure the business requirements are met by determining whether the software is ready for delivery or not to the end-user.

In other words, it determines whether the application responds to what the user wants it to.

Functional testing

Functional testing serves to analyze all the functions of the web application whether they work as expected or not. Functional testing involves testing the; user interface, APIs, security, database server applications, and overall the functionality of the website.

End-to-end testing

The idea of end-to-end testing is to replicate as closer as possible the user behaviour in a complete application environment. 

End-to-end tests aren’t cheap to run. Despite that this type of testing is very useful, it can be hard for maintenance, hence, it is recommended to have a few end-to-end test and pend more on unit and integration tests.

Smoke testing

This type of testing is done only after developed software functions are fully integrated in the final software. Meaning that, in case that any flaw or any bigger failure occurs at this stage, it will send the application back at the development team for modification and enhancing in accordance with the negative outcomes of the smoke testing.

The stability and viability of the software are assessed through smoke testing. Smoke testing means helping to preventing any catching fire(as the name tells) of the software on later stage. 

If the software features fail in smoke testing, it indicates that the software testers can’t go in next testing steps before fixing issues appeared of the software on this stage of testing.

Regression testing

As we know code is something that needs to be updated according to the evolution of technologies or because we want to change, add, remove something from our software, even though it is performing just fine. 

In these cases, changes in code can cause unpleasant situations, therefore it is required to test and monitor the performance of the software after these changes.

Regression testing is run especially for verifying that these recent changes in code aren’t affecting the exciting features of the software. In other words, it verifies that the old code works in the same level of performance as they were performing before making the new changes.

Performance testing

Developers are in pursuit of softwares that behave smooth in every kind of workload. Performance testing checks whether the software can perform at a high level and stay responsive and fast when dealing with multiple users as well.

Performance testing makes sure to simulate user traffic and test a software’s speed, stability and responsiveness under workload and identify possible bottlenecks. 

If any possible performance hurdles have been identified through performance testing, they need to be removed in order to optimize the software’s ability to perform in a higher level and be able to deliver the best results to the end user.

Frameworks used in automation software testing

The most popular automation frameworks include;

1. Linear Scripting framework

The creation and execution of test scripts are done individually for each test case. Testers capture each test step such as browsing, navigation, user inputs, enforcing checkpoints, and then play the scripts to carry out the tests.

This type of framework is used in applications of small sizes.

2. Data-Driven Automation 

In contrary to modular framework data-driven can easily pass and make the test scripts work properly for different sets of data.

Using this framework, the number of test scripts is significantly reduced and at the same time, it gives test coverage with reusable tests. Designing this framework requires coding skills and experience in test automation.

3. Keyword Driven Automation 

Otherwise known as action word-based test automation, it performs automation test scripts based only on the keywords specified in the excel sheet.

The tester is able to work with keywords to develop any test automation script. This framework has shares similarities with data-driven testing.

Even though it can take some time to design keyword-driven automation, it isn’t needed to be an expert in order to be able to write test scripts. Yet, employees with good test automation skills are needed. 

4. Modular Automation 

The complete application is broken down into smaller independent modules based on which testers create individual test scripts modules. These test scripts can be modified and combined to make larger test scripts to achieve the required scenario. 

5. Hybrid Automation 

As the name suggests, hybrid test automation is the combination of two or more frameworks. May teams are using this framework in the current market attempting to leverage the strengths of other frameworks.

6. Behaviour Driven Development 

The aim of this framework is to develop a multi-functional platform that allows business analysts, developers, testers, etc. to continuously participate.

For a more successful implementation of this framework, development and test teams need to increase and deepen their collaboration. 

How to automate tests

Every automation test needs to go through four steps.

  1. Choose a test automation tool and a framework that best fits your needs and budget as well.
  2. After deciding with which automation tool and framework you want to test the software, you need to define your test cases. In other words, you need to write down every single step and the outcomes you look forward to receive. You don’t want to miss any steps that manual testers might take.
  3. In this stage you need to convert you test case into a test that can run in the chosen framework. Check if you test actually works properly and that it works in every case you need to test. For example, make sure your test can work on every browser if your app needs to run on different browsers.
  4. Least but not least, run the test and examine the outcomes. Evaluating the outcomes isn’t easy process since many test failures can be false positives, triggered by minor changes in the application, which in this case you need to update the test and run it again for more accurate results. 

Test Cases That Need to Be Automated

You can automate the test cases based on the below conditions, which will also help you increase the ROI on automation.

  • When there is a high risk involved, such as business-critical test cases.
  • If you need to execute test cases repeatedly.
  • If test cases are tedious, and you are unable to execute them manually.
  • When test cases take more than expected time for execution.
Benefits of automation testing

In short, implementation and practicing successfully the automation testing helps in;

  • Maintaining consistency of Testing
  • Improves test structuring
  • Minimum usage of code
  • Less Maintenance of code
  • Improve re-usability
  • Non Technical testers can be involved in code
  • The training period of using the tool can be reduced
  • Involves Data wherever appropriate

As a bottom line we say that, automation testing definitely helps improve quality and that with speed. In the other hand, not every testing can be automated.
