TASK 14

QUE 1 : what is difference between Automated and Manual testing in Software development

Manual Testing

• Manual testing is testing of the software where tests are executed manually by a QA Analyst without the use of automation tools. It is performed to discover bugs in software under development.
• In Manual testing, the tester checks all the essential features of the given application or software.
• The tester executes test cases and generates test reports without any help from the automation tools.
• It is conducted by the experienced tester to accomplish the testing process.
• Manual testing allows testers to adapt quickly to changes in requirements or user interface designs, making it suitable for exploratory testing and ad-hoc scenarios.
• Manual testing is essential for evaluating aspects of usability, user experience, and user interface design that cannot be easily automated.

Automation Testing

• In Automated Software Testing, testers write code/test scripts to automate test execution. Testers use appropriate automation tools to develop the test scripts and validate the software. The goal is to complete test execution in a less amount of time.
• It is faster than manual testing because it is done with some automation tools. There is no chance of any human errors.
• Automated testing entirely relies on the pre-scripted test which runs automatically to compare actual result with the expected results. This helps the tester to determine whether or not an application performs as expected.
• Automated testing allows you to execute repetitive task and regression test without the intervention of manual tester. Even though all processes are performed automatically, automation requires some manual effort to create initial testing scripts.

REST Assured: (API)

• REST Assured is a popular Java library for testing RESTful APIs, commonly used in automated testing frameworks and tools.
• It provides a fluent interface for writing test cases and assertions, making it easy to create readable and maintainable tests.
• REST Assured integrates seamlessly with popular Java testing frameworks like JUnit and TestNG.

Apache JMeter: (Performance)

• JMeter is one of the most widely used open-source performance testing tools.
• It allows users to simulate various scenarios, including load testing, stress testing, and functional testing of web applications.
• JMeter supports multiple protocols (HTTP, HTTPS, SOAP, JDBC, etc.) and offers features for distributed testing, dynamic parameterization, and result analysis.

• It provides a comprehensive set of features for load testing, stress testing, and performance monitoring of applications.
• LoadRunner supports various protocols (HTTP, SOAP, JDBC, etc.) and offers integrations with CI/CD tools for automated testing.

QUE 3: what is cross browser testing

Cross-browser testing is the process of verifying that a web application functions correctly and consistently across different web browsers and browser versions. Since web browsers can interpret HTML, CSS, and JavaScript code differently, web applications may render and behave differently depending on the browser being used. Cross-browser testing ensures that users have a consistent and reliable experience regardless of the browser they choose to use.

• The primary objective of cross-browser testing is to identify and address any discrepancies or issues in how a web application is displayed or functions across different browsers.

• Verify that the layout, styling, and visual elements of the web application are consistent across browsers.

• Ensure that all features, interactions, and behaviors of the web application work as expected across browsers.

• Test the responsiveness and performance of the web application, including page load times and responsiveness to user interactions, across browsers.

• Confirm that the web application is compatible with older versions of browsers, as well as newer versions and alternative browsers.

QUE 4: Write blog on TDD and BDD

Test Driven Development

• Test Driven Development is a development technique which focuses more on the implementation of a feature of a software application/product.
• Here, we create the test cases first and then write the code underlying those test cases. Although TDD is a development technique, it can also be used for automation testing development.
• The teams that implement TDD, take more time for development however, they tend to find very few defects. TDD results in improved quality of code and the code that is more reusable and flexible.
• TDD also helps in achieving high test coverage of about 90-100%. The most challenging thing for developers following TDD is to write their test cases before writing the code.

Benefits:

• Unit test provides constant feedback about the functions.
• Quality of design increases which further helps in proper maintenance.
• Test driven development act as a safety net against the bugs.
• TDD ensures that your application actually meets requirements defined for it.
• TDD have very short development lifecycle.

Behavior Driven Development

• BDD is a software development approach that extends TDD by focusing on the behavior of the software from the perspective of its stakeholders.
• BDD emphasizes collaboration between technical and non-technical stakeholders to define and verify the behavior of the system through examples written in a common language.
• BDD is considered a best practice when it comes to automated testing as it focuses on the behavior of the application and not on thinking about the implementation of the code.
• The behavior of the application is the center of focus in BDD and it forces the developers and testers to walk-in the customer’s shoes.

Benefits:

• Greater clarity on business goals and customer requirements.
• Reaches a larger customer set as it uses non-technical languages.
• Helps in defining acceptance criteria before development.
• Focuses on the system’s behavior from the client’s and developer’s point of view.
• Collaboration between team members is promoted through BDD, involving all stakeholders in the development process to ensure a shared understanding of objectives.
• Detailed documentation of user stories, acceptance criteria, and step definitions can improve overall project documentation, facilitating maintenance and updates to the system.
