SOFTWARE TESTERS INTERVIEW QUESTIONS WITH ANSWERS-PART1
Here are some Software Testers Interview Questions
1What is the role of QA in development project?
Deploy and enforce standards Continually improve standards, QA process based on previous experiences, Promote effective means for reporting and communication.
2What is verification?
A: Verification ensures the product is designed to deliver all functionality to the customer; it typically involves reviews and
meetings to evaluate documents, plans, code, requirements and specifications; this can be done with checklists, issues lists, and
walkthroughs and inspection meetings.
3What is validation?
A: Validation ensures that functionality, as defined in requirements, is the intended behavior of the product; validation typically involves actual testing and takes place after verifications are completed.
- What is quality?
A: Quality software is software that is reasonably bug-free, delivered on time and within budget, meets requirements and expectations and is maintainable
- What is good code?
A: A good code is code that works, is free of bugs and is readable and maintainable.
- What is good design?
A: Design could mean to many things, but often refers to functional design or internal design. Good functional design is indicated by software functionality can be traced back to customer and end-user requirements. Good internal design is indicated by software code whose overall structure is clear, understandable, easily modifiable and maintainable; is robust with sufficient error handling and status logging capability; and works correctly when implemented.
- What is software life cycle?
A: Software life cycle begins when a software product is first conceived and ends when it is no longer in use. It includes phases
like initial concept, requirements analysis, functional design, internal design, documentation planning, test planning, coding,
document preparation, integration, testing, maintenance, updates, re- testing and phase-out.
- What is the role of documentation in QA?
A: Documentation plays a critical role in QA. QA practices should be documented, so that they are repeatable. Specifications, designs, business rules, inspection reports, configurations, code changes, test plans, test cases, bug reports, user manuals should all be documented. Ideally, there should be a system for easily finding and obtaining of
documents and determining what document will have a particular piece of information. Use documentation change anagement, if possible.
- What about requirements?
A: Requirement specifications are important and one of the most reliable methods of insuring problems in a complex software project is to have poorly documented requirement specifications. Requirements are the details describing an application’s externally perceived functionality and properties. Requirements should be clear, complete, reasonably detailed, cohesive, attainable and testable.
- What is a test plan?
A: A software project test plan is a document that describes the objectives, scope, approach and focus of a software testing effort. The process of preparing a test plan is a useful way to think through the efforts needed to validate the acceptability of a software product. The completed document will help people outside the test group understand the why and how of product validation. It should be thorough enough to be useful, but not so thorough that none outside the test group will be able to read it.
- What is a test case?
A: A test case is a document that describes an input, action, or event and its expected result, in order to determine if a feature of an application is working correctly. A test case should contain particulars such as a…
• Test case identifier
• Test case name
• Input data requirements/steps
• Expected results.
Please note, the process of developing test cases can help find problems in the requirements or design of an application, since it
requires you to completely think through the operation of the application. For this reason, it is useful to prepare test cases early
in the development cycle, if possible.
- What is software quality assurance?
A: Software Quality Assurance, is oriented to prevention. It involves the entire software development process. Prevention is
monitoring and improving the process, making sure any agreed-upon standards and procedures are followed and ensuring problems are found and dealt with.
- What is quality assurance?
A: Quality Assurance ensures all parties concerned with the project adhere to the process and procedures, standards and templates and test readiness reviews. A lot will depend on team leads or managers, feedback to developers and communications among customers, managers and testers.
- Standards and templates – what is supposed to be in a document?
A: All documents should be written to a certain standard and template. Standards and templates maintain document uniformity. It also helps in learning where information is located, making it easier for a user to find what they want.
- How do test case templates look like?
A: Software test cases are in a document that describes inputs, actions, or events, and their expected results, in order to determine if all features of an application are working correctly. Test case templates contain all particulars of every test case. Often these templates are in the form of a table. One example of this table is a 6- column table, where column 1 is the “Test Case ID Number”, column 2 is the “Test Case Name”, column 3 is the “Test Objective”, column 4 is the “Test Conditions/Setup”, column 5 is the “Input Data Requirements/ Steps”, and column 6 is the “Expected Results”. All documents should be written to a certain standard and template. Standards and templates maintain document uniformity. They also help in learning where
information is located, making it easier for users to find what they want
- Process and procedures – why follow them?
A: Detailed and well-written processes and procedures ensure the correct steps are being executed to facilitate a successful completion of a task.
- How do you create a test strategy?
A: The test strategy is a formal description of how a software product will be tested. A test strategy is developed for all levels of
testing, as required. The test team analyzes the requirements, writes the test strategy and reviews the plan with the project team. The test plan may include test cases, conditions, the test environment, a list of related tasks, pass/fail criteria and risk assessment.
- What is the general testing process?
A: The general testing process is the creation of a test strategy (which sometimes includes the creation of test cases), creation of a test plan/design (which usually includes test cases and test procedures) and the execution of tests.
- What is a test schedule?
A: The test schedule is a schedule that identifies all tasks required for a successful testing effort, a schedule of all test activities and resource requirements.
- What are the different levels of testing?
A. Each level of testing is either considered black or white box testing.
- What is black box testing?
A: Black box testing is functional testing, not based on any knowledge of internal software design or code. Black box testing are based on
requirements and functionality.
- What is white box testing?
A: White box testing is based on knowledge of the internal logic of an application’s code. Typically done by developers.
- What is unit testing?
A: Unit testing is the first level of dynamic testing and is first the responsibility of developers and then that of the test engineers. Unit testing is performed after the expected test results are met or differences are explainable/acceptable.
