What is Boundary Value Analysis?

A black-box test design technique in which test cases are designed based on boundary values.

What is Equivalence Partitioning?

A black-box test design technique in which test cases are designed to execute representatives from equivalence partitions.

What is Test Driven Development (TDD)?

A software development process that relies on the repetition of a very short development cycle: requirements are turned into very specific test cases, then the software is improved to pass the new tests.

What is Behavior-Driven Development (BDD)?

Understand Behavior-Driven Development (BDD), an agile software development process that encourages collaboration.

What is Alpha Testing?

Simulated or actual operational testing by potential users/customers or an independent test team at the developers' site.

What is Beta Testing?

Operational testing by potential and/or existing users/customers at an external site not otherwise involved with the developers.

What is Mutation Testing?

A method of software testing which involves modifying a program in small ways to check if the test suite detects the changes.

What is Fuzz Testing?

Understand fuzz testing, an automated testing technique that involves providing invalid, unexpected, or random data as inputs.

What is Static Testing?

Learn about static testing, a software testing technique where the code is not executed.

What is Dynamic Testing?

Understand dynamic testing, a technique where the software is executed to validate its behavior.

What is API Testing?

Testing of an API (Application Programming Interface) directly and as part of integration testing to determine if it meets expectations.

What is System Testing?

The process of testing an integrated system to verify that it meets specified requirements.

What is Test Automation?

The use of special software (separate from the software being tested) to control the execution of tests and the comparison of actual outcomes with predicted outcomes.

What is the Defect Lifecycle?

Understand the defect lifecycle (bug lifecycle), the journey of a defect from its discovery to closure.

What is Test Plan?

A document describing the scope, approach, resources and schedule of intended test activities.

What is Test Case?

A set of conditions or variables under which a tester will determine whether a system under test satisfies requirements or works correctly.

What is Test Suite?

A collection of test cases that are intended to be used to test a software program to show that it has some specified set of behaviours.

What is a Traceability Matrix?

Understand the Requirements Traceability Matrix (RTM) and how it ensures test coverage.

What is Agile Testing?

Software testing practice that follows the principles of agile software development.

What is Shift-Left Testing?

Understand shift-left testing, a practice of moving testing earlier in the software development lifecycle.

What is Continuous Testing?

Learn about continuous testing, the process of executing automated tests as part of the software delivery pipeline.

What is User Acceptance Testing (UAT)?

Formal testing with respect to user needs, requirements, and business processes conducted to determine whether or not a system satisfies the acceptance criteria.

What is Automated Testing?

The use of software separate from the software being tested to control the execution of tests and the comparison of actual outcomes with predicted outcomes.

What is Bug?

An imperfection in a computer program that causes it to produce an incorrect or unexpected result, or to behave in unintended ways.

What is Bug Life Cycle?

The specific set of states that a bug or defect goes through from discovery to defect resolution.

What is Compatibility Testing?

Testing to determine the compatibility of a software product with other elements of a system.

What is Component Testing?

The testing of individual software components.

What is Continuous Integration?

A software engineering practice in which isolated changes are immediately tested and reported on when they are added to a larger code base.

What is Defect?

A flaw in a component or system that can cause the component or system to fail to perform its required function.

What is Edge Case?

A problem or situation that occurs only at an extreme (maximum or minimum) operating parameter.

What is End-to-End Testing?

A methodology used to test whether the flow of an application is performing as designed from start to finish.

What is Functional Testing?

Testing based on an analysis of the specification of the functionality of a component or system.

What is Manual Testing?

The process of manually testing software for defects.

What is Mock Object?

Simulated objects that mimic the behavior of real objects in controlled ways.

What is Negative Testing?

Testing to confirm that the system handles invalid input or unexpected user behavior properly.

What is Non-functional Testing?

Testing the attributes of a component or system that do not relate to functionality, e.g. reliability, efficiency, usability, maintainability and portability.

What is Security Testing?

Testing to determine the security of the software product.

What is Test Coverage?

A measure used to describe the degree to which the source code of a program is executed when a particular test suite runs.

What is Test Environment?

A setup of software and hardware on which the testing team is going to perform the testing of the software product.

What is Test Script?

A set of instructions that will be performed on the system under test to test that the system functions as expected.

What is HTTP 400 Bad Request?

Status code indicating that the server cannot or will not process the request due to something that is perceived to be a client error.

What is HTTP 401 Unauthorized?

Status code indicating that the request has not been applied because it lacks valid authentication credentials for the target resource.

Status code indicating that the origin server did not find a current representation for the target resource.

What is HTTP 500 Internal Server Error?

Status code indicating that the server encountered an unexpected condition that prevented it from fulfilling the request.
