What is Automation Testing?
Automation testing is a software testing method in which automation scripts and tools interact with the software applications to execute tests. The test script automatically performs tests on the software without human intervention and shows the output as pass or fail. This technique helps improve the testing process’s efficiency, effectiveness, and accuracy.
Continuous integration and continuous deployment are made possible by different types of automated testing, which also speeds up test execution (CI/CD). It assists in reducing the time and effort needed to complete labor-intensive, repetitive tasks that are challenging to complete by hand.
Different levels of automation testing can be carried out, such as:
- API Testing: Validating application programming interfaces’ functionality, reliability, and security (APIs).
- Unit-level Automation: Testing individual components or units of code to ensure they work as expected.
- User Interface (UI) Testing: Assessing the usability and functionality of the application’s user interface to ensure it meets design specifications and provides a good user experience.
Why Automation Testing?
There are many reasons why automation testing is helpful for software applications.
- Quality Assurance Automation testing cuts down on the manual work needed for repeated tasks. This lowers human errors and boosts the overall quality of the software. It ensures more thorough test coverage, allowing more features and functions to be tested fully.
- Error or Bug-Free Software Automated tests are great at finding bugs and issues, leading to a more reliable and stable software product. They can quickly run full test suites, catching bugs that might be missed during manual testing.
- No Human Intervention Automation testing removes the need for constant human involvement. This means tests can run by itself, freeing up resources for other tasks. This results in more consistent and reliable test execution.
- Increased Test Coverage Automated testing can handle more test scenarios and edge cases than manual testing. This wide coverage helps find problems that manual testing might miss.
- Frequent Testing Automation testing allows for frequent test runs, supporting continuous integration and continuous deployment (CI/CD) practices. Regular testing cycles improve software quality by finding and fixing issues early. ## Types of Automation Testing
There are two major types of Automation Testing i.e., Functional Testing and Non- Functional Testing. We will learn about them in detail in the upcoming sections.
Functional Testing
Functional testing refers to software testing in which the functionality of a software application is evaluated by testing it against the specified requirements and checking if the outputs meet the expected or desired outcomes. Functional Testing tools aim to ensure software functions per the desired specifications and perform its intended tasks efficiently.
Types of Functional Testing
This section will help explore various functional testing types to ensure software quality and deliver a flawless product to end-users.
Unit Testing
Unit testing is a software testing method that focuses on verifying the functionality of individual units or components of a software system. A unit is the smallest testable part of a program, often a function, method, or class.
The main purpose of unit testing is to isolate and test each unit of code separately to ensure it performs as intended. By testing individual units in isolation, developers can easily identify and fix bugs early in the software development lifecycle (SDLC) before integrating the units into a larger system. Unit testing improves code quality by ensuring each unit behaves correctly according to its specifications or requirements.
Unit testing helps reduce the number of bugs and enhance the security of software design. Examples of unit testing tools include JUnit, NUnit, TestNG, and PHPUnit. These tools test the source code, ensuring its reliability and robustness.
Integration Testing
Integration Testing is a software testing technique that focuses on testing the integration and interaction between different modules, components, or subsystems of a software system. It ensures that individual elements work together as expected and that the integrated system functions properly.
Integration testing aims to identify defects that may arise when combining and interacting with different components. It verifies that interactions between different parts of the system, such as modules, classes, databases, APIs, or external systems, are seamless and produce the desired outcomes.
Integration testing tools facilitate the testing interactions and communication between software components. These tools offer user-friendly features that follow best practices in integration testing, speeding up the testing process while reducing concerns about maintenance and reporting.
Regression Testing
Regression Testing is a software testing practice aimed at verifying that changes or enhancements made to an application have not introduced new bugs or caused unintended side effects. It involves retesting previously tested functionality to ensure it works as expected after modifications.
The primary focus of regression testing is to catch any defects or issues that may have been introduced due to changes in the software. It ensures that existing functionality remains intact and unaffected by modifications or additions made during the development process.
Regression testing tools automate the execution of previously run test cases, ensuring the application maintains its expected behavior after modifications. Examples of these tools include Selenium, Appium, TestGrid, and Watir, etc.
Smoke Testing
Smoke Testing is an essential type of software testing performed to quickly assess the stability and basic functionality of an application or system after a new build or major changes have been made. The goal is to identify any major issues that might indicate critical flaws, which could hinder further testing or deployment.
Smoke testing serves as an initial check to ensure that critical functionalities of the software are working as intended. This basic examination verifies the software’s stability before more rigorous testing begins. By running predetermined tests on essential features, smoke testing helps identify severe defects early. This allows developers to address these issues promptly and avoid wasting time and resources on further testing.
Smoke testing tools automate preliminary tests on new software builds to ensure basic functionalities work correctly. They quickly verify that critical features are functioning, allowing developers to proceed with detailed testing. These tools automate basic test cases such as launching the application, performing UI interactions, and handling simple data processing. Examples include Jest, Cypress, Selenium, and Postman, etc.
Acceptance Testing
Acceptance testing is functional testing that focuses on evaluating a software’s readiness for deployment and its alignment with the requirements and expectations of end users or stakeholders. This crucial phase determines whether the software meets the agreed-upon acceptance criteria and is suitable for acceptance or approval by the intended users.
The primary purpose of acceptance testing is to ensure that the software satisfies the desired functionality, usability, and overall quality standards. It validates that the software fulfills business objectives and user needs, confirming its readiness for deployment in the production environment.
Acceptance testing can take different forms, such as:
- User Acceptance Testing (UAT): End-users or representatives from the client organization validate the software to ensure it meets their requirements and expectations.
- Operational Acceptance Testing (OAT): Verifies the software’s operational readiness and compatibility with the production environment. Tools commonly used for acceptance testing include Selenium, Cucumber, JMeter, and SoapUI. These tools help automate the testing process, ensuring the software meets all necessary criteria before release.
Non-Functional Testing
Non-functional testing refers to software testing that evaluates the non-functional aspects of a software application, assessing criteria not covered by functional testing. It focuses on performance, reliability, usability, efficiency, maintainability, and scalability. This type of testing is crucial for ensuring the software meets standards and delivers a high-quality user experience.
