TOP Manual Testing Interview Questions and Answers
What is Acceptance Testing?
Testing conducted to enable a user/customer to determine whether to accept a software product. Normally performed to validate the software meets a set of agreed acceptance criteria.
What is Accessibility Testing?
Verifying a product is accessible to the people having disabilities (deaf, blind, mentally disabled etc.).
What is Ad-Hoc Testing?
A testing phase where the tester tries to ‘break’ the system by randomly trying the system’s functionality. Can include negative testing as well. See also Monkey Testing.
What is Agile Testing?
Testing practice for projects using agile methodologies, treating development as the customer of testing and emphasizing a test-first design paradigm. See also Test Driven Development.
What is Application Binary Interface (ABI)?
A specification defining requirements for portability of applications in binary forms across different system platforms and environments.
What is Application Programming Interface (API)?
A formalized set of software calls and routines that can be referenced by an application program in order to access supporting system or network services.
What is Automated Software Quality (ASQ)?
The use of software tools, such as automated testing tools, to improve software quality.
What is Automated Testing?
Testing employing software tools which execute tests without manual intervention. Can be applied in GUI, performance, API, etc. testing. The use of software to control the execution of tests, the comparison of actual outcomes to predicted outcomes, the setting up of test preconditions, and other test control and test reporting functions.
What is Backus-Naur Form?
A metalanguage used to formally describe the syntax of a language.
What is Basic Block?
A sequence of one or more consecutive, executable statements containing no branches.
What is Basis Path Testing?
A white box test case design technique that uses the algorithmic flow of the program to design tests.
What is Basis Set?
The set of tests derived using basis path testing.
What is Baseline?
The point at which some deliverable produced during the software engineering process is put under formal change control.
What is Beta Testing?
Testing of a re-release of a software product conducted by customers.
What is Binary Portability Testing?
Testing an executable application for portability across system platforms and environments, usually for conformation to an ABI specification.
What is Black Box Testing?
Testing based on an analysis of the specification of a piece of software without reference to its internal workings. The goal is to test how well the component conforms to the published requirements for the component.
What is Bottom Up Testing?
An approach to integration testing where the lowest level components are tested first, then used to facilitate the testing of higher level components. The process is repeated until the component at the top of the hierarchy is tested.
What is Boundary Testing?
Test which focus on the boundary or limit conditions of the software being tested. (Some of these tests are stress tests).
What is Bug?
A fault in a program, which causes the program to perform in an unintended or unanticipated manner.
What is Defect?
If software misses some feature or function from what is there in requirement it is called as defect.
What is Boundary Value Analysis?
BVA is similar to Equivalence Partitioning but focuses on “corner cases” or values that are usually out of range as defined by the specification. his means that if a function expects all values in range of negative 100 to positive 1000, test inputs would include negative 101 and positive 1001.
What is Branch Testing?
Testing in which all branches in the program source code are tested at least once.
What is Breadth Testing?
A test suite that exercises the full functionality of a product but does not test features in detail.
What is CAST?
Computer Aided Software Testing.
What is Capture/Replay Tool?
A test tool that records test input as it is sent to the software under test. The input cases stored can then be used to reproduce the test at a later time. Most commonly applied to GUI test tools.
What is CMM?
The Capability Maturity Model for Software (CMM or SW-CMM) is a model for judging the maturity of the software processes of an organization and for identifying the key practices that are required to increase the maturity of these processes.
What is Cause Effect Graph?
A graphical representation of inputs and the associated outputs effects which can be used to design test cases.
What is Code Complete?
Phase of development where functionality is implemented in entirety; bug fixes are all that are left. All functions found in the Functional Specifications have been implemented.
What is Code Coverage?
An analysis method that determines which parts of the software have been executed (covered) by the test case suite and which parts have not been executed and therefore may require additional attention.
What is Code Inspection?
A formal testing technique where the programmer reviews source code with a group who ask questions analyzing the program logic, analyzing the code with respect to a checklist of historically common programming errors, and analyzing its compliance with coding standards.
What is Code Walkthrough?
A formal testing technique where source code is traced by a group with a small set of test cases, while the state of program variables is manually monitored, to analyze the programmer’s logic and assumptions.
What is Coding?
The generation of source code.
What is Compatibility Testing?
Testing whether software is compatible with other elements of a system with which it should operate, e.g. browsers, Operating Systems, or hardware.
What is Component?
A minimal software item for which a separate specification is available.
What is Component Testing?
Testing of individual software components (Unit Testing).
What is Concurrency Testing?
Multi-user testing geared towards determining the effects of accessing the same application code, module or database records. Identifies and measures the level of locking, deadlocking and use of single-threaded code and locking semaphores.
What is Conformance Testing?
The process of testing that an implementation conforms to the specification on which it is based. Usually applied to testing conformance to a formal standard.
What is Context Driven Testing?
The context-driven school of software testing is flavor of Agile Testing that advocates continuous and creative evaluation of testing opportunities in light of the potential information revealed and the value of that information to the organization right now.
What is Conversion Testing?
Testing of programs or procedures used to convert data from existing systems for use in replacement systems.
What is Cyclomatic Complexity?
A measure of the logical complexity of an algorithm, used in white-box testing.
What is Data Dictionary?
A database that contains definitions of all data items defined during analysis.
What is Data Flow Diagram?
A modeling notation that represents a functional decomposition of a system.
What is Data Driven Testing?
Testing in which the action of a test case is parameterized by externally defined data values, maintained as a file or spreadsheet. A common technique in Automated Testing.
What is Debugging?
The process of finding and removing the causes of software failures.
What is Defect?
Non conformance to requirements or functional / program specification
What is Dependency Testing?
Examines an application’s requirements for pre-existing software, initial states and configuration in order to maintain proper functionality.
What is Depth Testing?
A test that exercises a feature of a product in full detail.
What is Dynamic Testing?
Testing software through executing it. See also Static Testing.
What is Emulator?
A device, computer program, or system that accepts the same inputs and produces the same outputs as a given system.
