Automation testing is essential in software development as it enhances cloud testing efficiency and extends the automation testing stage. In today’s fast web application environment, developers and testers must embrace automation testing methods. Automation testing involves running pre-written tests on a software application to verify its dependability and quality.
Creating and running automated test scripts to compare anticipated and real outcomes is part of the process. This blog will be a detailed guide for automation testing in your software development cycle.
What is Automation Testing?
Automation testing utilizes specialized software tools to perform pre-written tests on a software program without requiring manual participation. This technique simplifies and effectively validates software functionality, performance, and reliability.
The first step is to write test scripts detailing the testing process steps.
These scripts can handle various situations, from basic tasks to more advanced scenarios. Automation testing tools then run these scripts against the software being tested, comparing actual and predicted results.
Automated testing offers several benefits compared to manual testing, such as quicker processing, consistency, increased scope, and reduced likelihood of human mistakes.
Conducting multiple tests in regression testing to verify new code changes do not affect current functionality is particularly beneficial.
In addition, automation testing enables the smooth process of continuous integration and continuous delivery (CI/CD) pipelines, leading to quicker and more frequent software releases.
Nonetheless, implementing automated testing requires a significant initial investment in selecting tools, developing scripts, and maintaining them.
Moreover, some types of testing, like exploration tests and usability testing, still need manual participation to ensure full test coverage.
Benefits of Automation Testing
Here are a few reasons why developers and testers should adapt automation testing in their software development cycle:
- Increased Efficiency: Automated tests can be run significantly faster than manual tests, delivering faster feedback on software quality and accelerating total development.
- Reuse of test scripts: It involves utilizing automated test scripts multiple times, reducing time and effort in regression testing while ensuring consistent test coverage.
- Increased Test Coverage: Automation enables thorough testing of different scenarios, such as edge cases and error conditions that are difficult or time-consuming to test by hand.
- Consistency and Precision: Automated tests follow the same procedures accurately every time they are executed, reducing the likelihood of human mistakes and ensuring reliable test outcomes.
- Cost-Effectiveness: Despite the initial investment required to set up automation frameworks and develop test scripts, automation ultimately lowers testing expenses by cutting down on time and resources, particularly for recurring tests
- Early release of applications: Automation testing results in early releases as it speeds up the testing process, automates repetitive tasks, and provides faster feedback on software’s quality
- Early detection of bugs: Automation testing identifies bugs early in the development process, which helps the team quickly address and resolve issues.
- Assistance with integration and deployment: Automation testing can easily be incorporated into CI/CD pipelines, allowing for automated testing during deployment and guaranteeing that changes can be released without manual involvement.
- Scalability: Automated tests can expand in size and complexity as software systems evolve, enabling teams to adjust to program modifications and improve test coverage.
- Enhanced teamwork: Automation testing encourages cooperation among developers, testers, and stakeholders by offering reliable feedback on the quality and readiness of the application for release.
Components of Automation Testing
Automation Testing consists of several components such as :
Test Automation Tools
These tools automate the process of running test cases. Selenium WebDriver, Appium, Cypress, and JUnit are used to test web and mobile apps, and Postman and SoapUI are tools specifically for testing APIs.
Test scripts
The scripts can be created for automation testing by writing them in various coding languages like Java, Python, etc. These scripts detail the steps to take on the tested application and the expected results.
Test frameworks
Test frameworks give a structure and rules for organizing and running automated tests.
They assist with managing test cases, generating reports, and connecting with Continuous Integration (CI) systems. Commonly used frameworks include TestNG, JUnit, Robot Framework, and NUnit.
Test data
Test data are the inputs, parameters, or variables used during test execution. It offers legitimate and invalid data to test the application’s functionality under various conditions. Test data management guarantees that test data is available, consistent, and secure.
Test Environment Setup
Automation testing demands a stable and consistent test environment near the production environment. This comprises configuring software, hardware, networks, databases, and other dependencies required for test execution.
Reporting and analysis
Automation testing generates test reports summarizing test execution results, such as pass/fail status, issues, and identified defects. Examining these reports allows you to identify problems, monitor testing advancements, and use data to enhance test coverage and application quality.
Maintenance and Version Control
Test automation requires continuing maintenance to update test scripts, adapt application changes, and improve test coverage. Git and other version control systems help manage changes to test scripts, enabling cooperation, traceability, and reproducibility of tests.
Test Execution
Test Execution involves running automated test scripts on the application being tested. Test execution can be initiated manually or integrated into continuous integration (CI) pipelines for consistent and automated testing during software development.
How to Perform Automation Testing?
Performing automation testing requires several critical steps:
- Identify Test Scenarios: Decide which test cases or scenarios are appropriate for automation. Focus on repeated, time-consuming, or crucial tests that can be automated.
- Pick the correct testing tool: Select suitable automated testing tools that can fulfill the project’s needs, like technology and financial resources. Some relevant and preferred tools among the testers and QA teams are Selenium WebDriver for web applications, Appium for mobile apps, and Postman for API testing.
- Set Up Test Environment: Create a stable and consistent test environment similar to the production environment. This comprises installing software and setting up hardware, networks, databases, and other needs.
- Create Test Scripts: Create test scripts with specified automation tools and programming languages like Java, Python, or JavaScript. Create test steps, assertions, and data inputs to automate the execution of test cases.
- Improve Test Scripts: Add strong error handling, synchronization, and reusable routines to make test scripts more efficient, maintainable, and scalable. Use design patterns and best practices to enhance script quality and readability.
- Execute test scripts: Run test scripts for the application being tested. Run tests locally on developer machines or integrate them into Continuous Integration (CI) pipelines to execute testing as part of the software development process.
- Iterate and Improve: Constantly examine and analyze automation testing methods to improve test coverage, efficiency, and effectiveness. Collect input from team members and stakeholders to identify areas for improvement and execute required changes.
Following these procedures will allow teams to efficiently do automation testing to check product functionality, improve quality, and accelerate the software development lifecycle.
