2) Why is Software Testing necessary?
Software Testing is necessary to ensure the quality and reliability of the software product. It helps identify bugs, improve functionality, and prevent costly errors after release. Testing ensures that the product meets the user's needs and complies with regulatory and performance requirements.
3) What are the different types of Software Testing?
There are several types of Software Testing, including Functional Testing (like Unit Testing, Integration Testing, System testing), Non-functional Testing (like Performance Testing, Security Testing), Manual Testing, and Automated Testing. Each type focuses on different aspects of the software’s functionality and performance.
4) What is a test case?
A test case is a set of specific conditions or variables under which a tester determines that one or more aspects of the system work properly. A test case typically includes input data, execution steps, and expected results which ensure that the software is consistent with the requirement.
5) What is Exploratory Testing?
Exploratory Testing is a testing approach where testers actively explore the system without predefined test cases. The tester interacts with the application, discovering defects and issues while learning the application’s behaviour in real-time.
6) What is End-to-end Testing?
End-to-end Testing is the validation of the entire flow of the application from start to end. It proves that the integrated components of the system work as expected and meet the requirements of the users by simulating real-world scenarios.
7) What is a test report?
A test report is a document summarising the activities and results of testing. It's usually an information report giving specifics about which tests were run, the outputs, defects identified, and coverage achieved as a whole. This then helps the stakeholders make some decisions of quality regarding the software.
8) What is a test suite?
A test suite is a collection of test cases aimed at testing a functionality or feature of a software application. It organises tests in a meaningful order and ensures that different scenarios are cared for to ensure full coverage.
9) What is A/B Testing?
A/B Testing refers to the methodology whereby you compare two versions, A and B, of a feature or a product to identify which performs better in relation to user engagements or other metrics. In most cases, it comes under UX Testing to fine-tune interfaces that are closer to delivering better user results.
10) What is Dynamic Testing?
Dynamic Testing is the execution of software under study with analysis in a run-time environment. This is helpful to detect defects by validating the response of software in relation to input and to ensure that it functions according to design.
11) What is a test plan and contents available in a test plan?
A test plan is a well-planned document that summarises the goals, scope, methodology, and means of testing required. Its contents typically consist of the test strategy, environment, test objectives, test deliverables, resource planning, test schedule, and risk analysis.
