Discover How is Java useful for Software Testers? Learn how Java helps in automation testing, scripting, and building robust test frameworks for QA professional.
What is Software Testing?
Ever wondered how the software we use daily works flawlessly, giving you a great experience and a hassle-free chain of handling various tasks and outcomes? Software testing is your answer. In the Software Development life-cycle, the software goes through many phases, of which testing is one of the crucial parts.
Why is Software Testing needed?
Software Testers ensure the identification of bugs and errors in the early stages of software development to provide a smooth experience for users plus it saves the company a lot of money by avoiding future failure of the software due to lack of insufficient testing. You can learn Software Testing through various courses online and training institutes like SevenMentor which offer practical training and in-depth knowledge about software testing and industry-standard tools for testing.
What Role does Java play in Software Testing?
Java is an object programming language, apart from being a great programming language for development, Java is also a game changer due to its versatility and reliability making Java a top choice for software testers for building and testing automation frameworks.
Learning Java is essential for software testers who want to move from manual testing to automated testing.
Why particularly Java? Can’t I use any other programming language?
Software testers highly value Java, especially in automated testing due to these factors:
- Java is platform-independent. Java’s nondependency on any platform offers testers great flexibility between different platforms as far as the platform has JVM running, ensuring cross-platform testing.
- The robustness and versatility of Java make it a great language for creating a wide range of testing frameworks, from simple to complex automation testing processes.
- Java integrates seamlessly with popular testing tools like JUnit, Selenium, and TestNG.
- Java can integrate with CI/CD tools like Jenkins allowing constant testing and deployment of the software. This helps in accelerating the software testing process avoiding any unnecessary halts when time and effectivity of the project is essential.
- Java’s popularity has made available ample learning resources, tutorials, courses and community support. At SevenMentor we thoroughly cover Software Testing and Java for SoftwareTesting in crafted training programs for students and professionals.
- Java’s syntax and structure is feasible for testers to not get confused while reading code making it easier to maintain, update, and collaborate on test automation processes.
Top Java Testing Frameworks and Tools
- Selenium: Selenium is the most common open source and is widely used for browser automation. It creates scripts written in Java to create efficient automation scripts for web applications. Selenium tests can be executed across various operating systems like Windows, MacOS, Android, IOS, etc.
- JUnit: JUnit is an open-source framework that is considered one of the best and most reliable for conducting unit tests. Effectively developing and carrying out unit testing for an application is the main goal of the JUnit testing framework and integration testing.
- TestNG: Test Next Generation also known as TestNG is used to create unit tests and automation tests, TestNG is an easier version derived from JUnit with a lot more functionalities. It can also parameterize tests, allowing developers to run the same tests with different sets of data.
- SerenityBDD: SerenityBDD is an open-source testing framework designed to simplify writing automated acceptance tests and regression tests. It is versatile and easy to maintain with reports on progress and data on the tests and keeps tabs of how many requirements have been mapped with respect to testing providing a better functional test coverage report.
Java Automation Software Testing Methods
Unit Testing: Unit testing is about finding and fixing each piece of code in isolation, this helps developers to detect and rectify the issues in the early stage of the development.
Why is Unit Testing needed?
The individual components of code are tested in isolation to ensure they function as intended. Frameworks like JUnit or TestNG are used to write unit tests for automating tests. Unit testing keeps the modularity and maintainability so that any changes to the code do not break the previous functionality.
Integration Testing: In Integration testing multiple parts of software are grouped together and then tested as a group. Integration Testing is the next step after Unit Testing.
What does Integration Testing achieve?
The main goal of Integration testing is to check if different software components are working seamlessly together and not break down when multiple packages are used at the same time.
Integration Testing is suitable for large projects with several sub-projects. It is not preferred for small-scale projects as it is high in cost.
Performance Testing: Performance testing is carried out to ensure that the product is ready for real-world use cases. The application must go under vigorous testing to determine the performance of the final product and is not unstable.
How does Performance Testing Ensure the Reliability of the Software?
Various factors like several users, multiple activities at the same time, etc should not affect the performance, stability, speed, and reactivity and should not cause the system to fail under a heavy workload. It also tests the system performance to scale to new versions and bring updates.
In modern times automated software testing is reducing a lot of manual workload where necessary, making Quality Assurance not seem too overwhelming. Java has relieved a lot of testers from manual testing and has brought dynamic changes with automation and better frameworks in the testing ecosystem. Finding the right Java frameworks that work for you and choosing the right tools to integrate for the automation of tests and even in manual testing reduces the risk of cost. It strives to provide a reliable and smooth software experience and is a pivotal step in the software development process.
