Tester Interview Questions and Answers for Freshers

Testing is the process of evaluating a system or its component(s) with the intent to find whether it satisfies the specified requirements or not.

• Testing is a process of identifying defects or errors in software applications.

• Waterfall model is a linear sequential approach where testing is done at the end of the development cycle.

• Agile method is an iterative approach where testing is done throughout the development cycle.

• Test case is a set of conditions or variables under which...read more

Test scenario is a high-level description of the functionality to be tested, while test case is a detailed step-by-step procedure to test a specific scenario.

• Test scenario is a broad description of what needs to be tested

• Test case is a specific set of steps to test a particular scenario

• Test scenario can have multiple test cases

• Test case includes preconditions, inputs, expected outputs, and post-conditions

• Test case should be repeatable and independent

The bug life cycle refers to the stages a bug goes through from discovery to resolution.

• Bug is reported

• Bug is assigned to a tester

• Tester reproduces the bug

• Bug is logged in a bug tracking system

• Bug is prioritized and assigned to a developer

• Developer fixes the bug

• Tester verifies the fix

• Bug is closed

Black box testing is a software testing technique where the internal structure, design, and implementation of the system are not known to the tester.

• Black box testing focuses on the functionality of the system.

• Test cases are designed based on the system's requirements and specifications.

• The tester does not have access to the source code or the internal workings of the system.

• It verifies if the system behaves as expected from the end-user's perspective.

• Examples include input v...read more

SDLC stands for Software Development Life Cycle. It is a process used to develop software applications.

• SDLC is a systematic approach to software development that includes planning, designing, coding, testing, and maintenance.

• It provides a framework for developers to follow and ensures that the software is developed efficiently and meets the requirements.

• The different phases of SDLC include requirements gathering, system design, coding, testing, deployment, and maintenance.

• Eac...read more

Java tester rules ensure effective testing practices, maintainability, and quality assurance in software development.

• Follow the AAA pattern: Arrange, Act, Assert. Example: Set up test data, execute the method, and verify the output.

• Use meaningful test names that describe the purpose. Example: 'shouldReturnTrueWhenInputIsValid'.

• Isolate tests to avoid dependencies. Example: Use mocks for external services.

• Maintain test independence; one test should not affect another. Example: ...read more

Static testing is a type of software testing where the code is not executed. Blackbox testing is a type of testing where the internal logic of the system is not known to the tester.

• Static testing involves reviewing the code, requirements, and design documents to find defects early in the development process.

• Blackbox testing focuses on testing the functionality of the software without knowing the internal code structure.

• Examples of static testing include code reviews, walkthro...read more
