There is a need for businesses to adopt test automation that ensures faster and quality releases along with saving considerable time, and efforts.

What is Automation Testing?

According to WIKI, automation testing is the use of software separate from the software being tested to control the execution of tests and the comparison of actual outcomes with expected outcomes.

Test automation can automate some repetitive but necessary tasks in a formalized testing process already in place, or perform additional testing that might be difficult to do manually.

Test automation can speed up the release cycles, increase coverage and ensures quality software releases.

In manual testing, a human is involved to perform the manual tests that are more prone to human error and might even lack their correctness. This sort of human involved testing encloses many gaps which are seen and sometimes even have missed project timelines due to the huge number of misidentified bugs.

But, as automation testing involves the usage of tools and test scripts to test the software, the results are more reliable and delivers accurate results while testing various use cases and user scenarios.

Hence, this sort of automation testing ensures effective outcomes and can be successfully used by businesses to ensure faster and quality releases.

Automated testing is also known as test automation is a method in software testing that effectively makes use of special test automation tools. These tools are used to control the execution of tests using well-crafted test cases for each of the user scenarios and compares the actual test results to the predicted or the expected results.

It is actually a process that validates if the software is functioning appropriately and meeting the given requirements using these test automation tools.

What does Test Automation Do?

Automation testing meaning can be broadly defined as the process which involves running scripts that are executed by leveraging software testing tools. Automated test systems ensure high accuracy and reliability of the test results.

As no human observations are involved, it ensures more accurate test results. Moreover, this sort of automation testing using open source and paid test automation tools is most suitable for regression testing, performance testing, load testing, security testing along with other types of testing.

Significance of Automation in Testing for Enterprises?


Software testing is essentially an important part of the software development life cycle (SDLC) and should be taken up to ensure quality software.

Earlier manual testing was the major mode of testing but with advanced applications and connected devices in place, it is essential to have Test Automation to ensure faster and quality releases.

Even smaller and mid-sized companies in their quest to have good quality products continue to adopt test automation best practices to deliver high-performing products to their clients.

For enterprises, with automation in testing in place, there is a faster feedback cycle and that brings faster validation at various phases in product development.

The other benefit of automation testing is the testing procedure becomes automated as the test scripts are run by the test automation tools without much interference of QA.

Test automation also helps enterprises to improve the communication between DevOps, QA teams and product owners who depend on the results of these automated tests as these results are more reliable than the manual testing results.

It is more important to note that automation testing is best suitable for applications that need to be tested for various versions, platforms, and operating systems.

Test automation involves the usage of tests that are repeatable and can be run many times to test various conditions and scenarios.

It is best suited with regression tests and high-risk functionality tests to check whether they fail under real-time conditions.

These automated test results help to save businesses of any probable loss due to their application failure as with effective automated software testing the results are more reliable.

After having known about the various benefits of Automation testing, it is necessary to know about the different types of automation testing.

What are the Types of Automation Testing?

Types of Automation Testing

Unit Testing:

This is the first type of automation testing in which the individual components of an application are tested. These tests are usually written by the developers but sometimes automation testers also write them. These tests are usually performed during the software development phase.

Smoke testing:

This type of testing is performed to check whether the build is stable or not. If the build is not stable, then it will be sent back to the developers as an unstable build and if the build is stable then testers will accept it to perform further testing on the build.

Black box testing:

This form of testing is performed to check if there are any incorrect or missing functions, checks for the existence of any interface errors, or any behaviour related or performance errors and also checks the presence of termination errors if any.

Integration testing:

In this integration testing, the application modules are typically integrated logically and tested as a group. Essentially, this form of testing checks and verifies the data communication between different modules of the application.

Functional testing:

This form of testing is done to check if all the functions work as expected or not. This involves testing APIs, database, security testing and also tests the overall functionality of the application.

Regression testing:

This is an exhaustive testing methodology done to check whether all the existing features are functioning well even with recent code changes.

It basically verifies that the old code works in the same way as they were before making any changes to the code.

What are the Various Components of Automation Testing?

Components of Automation Testing

Automated unit tests:

These tests are primarily designed and crafted to test the software code. These tests categorically search for script errors, or if any bugs or any other issues within the written code.

Automated web services tests:

These tests are useful to test the user interface part of the web services. Protocols like SOAP and REST are used to test a web service.

This sort of testing determines the XML request and validates the response against the request sent which is achieved by the web services testing.

Automated API tests:

These tests allow the software to communicate effectively with other software applications. These API tests help to check the functionality and security of underlying layers.

Automated GUI tests:

These tests focus on testing the graphical user interface of the application under test.

It involves checking the screens with various controls like menus, buttons, icons, and all types of toolbars, menu bars dialogue boxes, and windows.

Automation Testing Tool Best Practices


Below listed are 6 best practices for test automation tool:

1. Select the right automation tool:

Testing teams must select the right automation testing tool that is in-line with their project requirements which helps them to execute automated test cases in an effective manner.

2. Design tests before automating them:

It’s always preferred and is considered as a good practice to create test cases before initiating the test automation process. A good test design will eventually help in finding defects and fixing them.

3. Don’t plan to automate unstable functionality:

Whenever there is a new feature or functionality that is to be tested, care should be taken such that automation testing will be taken up only for stable functionalities.

4. Decide which tests to automate:

Every feature cannot be automated as there are certain features that require manual testing. A proper automation test strategy needs to be put in place to fulfil all those test cases that need to be automated.

5. Early and frequent testing:

To leverage test automation, it is much better to start testing early on in the software development process. By running automated tests often, testers will be in a better position to detect bugs and resolve them at the earliest. This would save time and cost which would have been spent otherwise on fixing bugs at a later stage of the software development process.

6. Do not completely rely on UI test automation:

Completely relying on UI test automation is not considered as a best practice as every application might have some UI changes done. Hence, UI testing should be planned carefully to ensure the app delivers a great user experience to end-users.

Some of the Most commonly used Test Automation tools are:

What Does an Automation Tester Do?

automation tester

The QA automation tester and the automation test engineers are the main people involved to achieve test automation initiatives. They know how to automate for the successful roll-out of quality products for businesses.

The QA automation tester is responsible for designing and writing test automation scripts as the first phase and they use various types of test automation frameworks to achieve successful test automation.

They run test scripts to ensure all the scenarios are successfully tested and they have a close association with the developers and other QA analysts.

They log bugs and issues in various test management tools such that the developers work on these bugs and fix them.

Once again automated regression testing is done to ensure the new functionalities do not affect the functionalities of existing features.

What are Automation testing challenges and how to overcome them?


automation testing challenges

Though Test automation brings about a lot of advantages for enterprises. Typically, by using automated testing, an expedition of the process of software validation can be achieved along with achieving increased test coverage.

However, there are a lot of challenges in applying test automation for applications under test (AUT) which need a careful follow-up process to achieve successful test automation implementation.

1. Lack of Proper communication & collaboration between Developer and QA teams: 

Lack of proper interaction and collaboration between developers, QA automation engineers, and operations teams does not signify test automation success.

Hence, it is essential to place the entire team members to get involved in identifying test automation objectives and setting targets.

They also need to spend significant efforts on proper communication between teams to have a clear understanding of the requirements and project specifications to ensure test automation success.

2. Proper Selection of Right Test Automation Tool:

With the availability of a variety of automation testing tools for both open source and paid tools, it is necessary to evaluate properly before adopting a tool. A proper in-depth evaluation of the application under test (AUT) is required.

It should be carefully done and then the tool that appropriately matches the AUT should be chosen.

To overcome it, an expert QA test automation engineer can prove helpful to evaluate the tools based on the application that has to be tested.

3. Lack of Highly Skilled Test Automation Experts:

It is a truth that test automation requires efficient and industry rich technical skills to accurately design and maintain test automation framework and test scripts.

The team should properly build test scripts and maintain them to effectively run test scripts to verify the application performance and further resolve technical issues.

In order to overcome it, automated testing resource(s) should have a strong knowledge of the Test Automation framework’s design and implementation aspects to ensure effective automation is achieved.

4. Involves High Initial Investment Costs:

It is also a known fact that the initial phase of test automation is usually expensive as it is necessary to analyze, design and build a automation testing framework, libraries or reusable functions through a thorough analysis of the AUT.

Further, if a licensed test automation tool is selected, then the operating cost should be evaluated.

Else, if free open-source tools are chosen then also significant efforts should be spent on learning, training and maintaining them.

Hence based on the AUT priority and cost capability available therein, either open source or licensed tools should be selected.

5. Challenges with Scaling Test environments:

This is an important challenge today as QA teams that don’t provision test environments in the cloud, continue to face scalability challenges when they introduce test automation.

It is necessary to rapidly provision the different test environments that automated testing requires, scale them up, run the tests, tear them down, to ensure success while testing in the cloud.

The in-house (on-premise) teams usually have a limited number of test environments they can use, which means fewer tests they can deploy at any given time.

As a result, testing takes a much longer time. In order to overcome this, it is essential to move test environments to the cloud to scale the test automation and it will also reduce QA teams operating costs.

Automation Testing Vs Unit Testing

Criteria Automation Testing  Unit Testing 
Definition    Automation tools and scripts are used to execute test cases without manual intervention.    It is a type of testing wherein individual units or software components are tested in isolation. 
Purpose  Increase efficiency, speed, and coverage of the testing process. Especially beneficial for regression testing.   Validate that each unit of the software functions as designed. 
Tools  TPopular tools include Selenium, QTP, TestComplete, and Cucumber. They cater to various platforms and programming languages.  JUnit (for Java), NUnit (for . NET), and PHPUnit (for PHP) are widely used frameworks. 
Execution Time  Faster than manual tests once set up. Initial setup might take time.  Quick to write and execute, providing immediate feedback.
Scope  It can be used for different levels of testing, including unit, integration, and system testing.   It is strictly restricted to the testing of individual units or components. 
Benefits  – Efficient for large projects    – Consistent and reusable    – Higher accuracy due to reduced human error     – Helps in identifying issues early in the development cycle   – Facilitates code refactoring   – Enhances code quality   
Maintenance  Requires regular maintenance. Small changes in the code can break the test scripts.   Low maintenance. However, if software design changes, some unit tests may need revisions.
