Cognizant Quality Assurance Interview Questions and Answers

The software testing life cycle is a process that defines the various stages involved in testing a software application.

• It includes planning, designing test cases, executing tests, reporting bugs, and retesting.

• The stages may vary depending on the development methodology used, such as Agile or Waterfall.

• Examples of testing stages include unit testing, integration testing, system testing, and acceptance testing.

Severity refers to the impact of a defect on the system, while priority refers to the urgency of fixing the defect.

• Severity is the measure of how much a defect affects the system's functionality.

• Priority is the measure of how soon a defect needs to be fixed.

• Severity is usually categorized as low, medium, or high.

• Priority is usually categorized as low, medium, or high.

• For example, a spelling mistake in a button label ma...read more

Bug life cycle refers to the stages a bug goes through from identification to resolution.

• Bug is identified by QA team or users

• Bug is reported in a bug tracking system

• Bug is assigned to a developer for fixing

• Developer fixes the bug

• Bug is retested by QA team

• If bug is fixed, it is closed. If not, it is reopened

• Bug may go through multiple cycles before being resolved

Adhoc testing is informal testing without any predefined test cases or plans.

• Adhoc testing is performed randomly without any specific guidelines or documentation.

• It is usually done to explore the application and find defects that may not be covered in regular testing.

• Adhoc testing is not structured and is often performed by experienced testers who can think outside the box.

• Examples of adhoc testing include randomly cli...read more

Regression testing is the process of retesting a software application to ensure that new code changes have not adversely affected existing functionality.

• Repeating test cases that have been previously executed to verify that the unchanged parts of the software still perform as expected

Functional testing is a type of software testing that focuses on verifying that the software functions correctly according to the specified requirements.

• Tests the functionality of the software

• Verifies that the software behaves as expected

• Does not concern itself with the internal structure of the software

• Examples include testing user interfaces, APIs, databases, and integrations

Software development life cycle is a process used to design, develop, and test software applications.

• It consists of phases such as planning, analysis, design, implementation, testing, and maintenance.

• Each phase has specific goals and deliverables to ensure the quality and success of the software.

• Examples of SDLC models include Waterfall, Agile, and DevOps.

Error, bug, and issue are terms used in software testing to describe different types of problems.

• Error: A mistake made by a human that results in a fault in the software.

• Bug: A fault in the software that causes it to behave incorrectly or unexpectedly.

• Issue: A problem reported by a user or identified during testing that needs to be addressed.

• Example: Typing 'pritn' instead of 'print' in the code is an error. If this mi...read more

Regression testing ensures that new code changes do not adversely affect existing functionality, while sanity testing quickly checks if the software is ready for further testing.

• Regression testing is performed after code changes to ensure that existing functionality is not affected.

• Sanity testing is a quick test to check if the software is ready for further testing.

• Regression testing is comprehensive and covers all are...read more

A test pass is a collection of test runs, while a test run is a single execution of a test case.

• A test pass includes multiple test runs, which are iterations of executing test cases.

• A test run is a single instance of executing a test case to verify its functionality.

• Test passes are used to group and organize test runs for a specific testing phase or cycle.

• Test runs are typically recorded and documented to track the res

A test suite is a collection of test cases, while a test case is a specific set of conditions and inputs to test a particular aspect of the software.

• Test suite is a collection of test cases that are grouped together based on a common goal or functionality.

• Test case is a specific set of conditions, inputs, and expected results to test a particular aspect of the software.

• Test suite helps in organizing and managing test c...read more
