ISTQB Foundation - Chapter 1 - Fundamentals of testing Questions And Answers Latest Updates

Three categories of test case design techniques - ️️1) Black box techniques 2) White box techniques 3) Experience based techniques State transition testing - ️️Uses a state diagram to list out all of the possible states and transitions that can occur to ensure each are tested Test condition - ️️An item or event of a component or system that could be verified by one or more test cases Test case - ️️A set of input values, execution preconditions, expected results, and execution postconditions, such as to exercise a part of the code Test procedure specification - ️️A sequence of actions for the execution of a test Reasons to know test coverage - ️️1) Provide a quantitative measure of the quality of testing that has been done 2) Provides a way of estimating how much more testing is needed Specification based techniques - ️️Black box testing - test cases derived directly from a specification or a model of a system or proposed system (documentation) 5 types of specification based techniques - ️️1) Equivalence partitioning 2) Boundary value analysis 3) Decision table testing 4) State transition testing 5) Use case testing Equivalence partitioning - ️️Reduces the number of tests needed by considering partitions are the only test cases needed Boundary value analysis - ️️Looks for tests that focus on the possible boundaries of inputs, noting that most errors occur there Decision table testing - ️️Uses a table to list out all possible inputs and actions that can arise to ensure each are testedStructure-based techniques - ️️White box techniques - used to explore the system or component structures Statement testing - ️️Testing aimed at exercising programming statements Decision testing - ️️Testing aimed to ensure that the decisions in a program are adequately exercised Error guessing - ️️Uses tester's skill, intuition, and experience to identify special tests not easily captured otherwise Exploratory testing - ️️Combines experience of testing with a structured approach to testing where specifications are missing or inadequate and there is time pressure Experience based techniques - ️️Techniques that you fall back on when there is no adequate specification or no time to run the full set of tests Use case testing - ️️Capturing individual interactions between actors and the system to help test specific scenarios that are likely to be performed
