Socrative Week 5 Flashcards
What knowledge does the tester have about the software in black box testing?
No knowledge of inner workings of software
In black box testing, the tester accesses the system as a user would?
True
In black box testing, the SW system is a machine that?
Accepts input
Provides output
Makes changes based on the tester request
In black box testing, the tester focuses on whether or not the system operates as expected from the ___ perspective
User
In black box testing, the tester looks for user-facing defects which are defects the user would encounter
True
In black box testing, the tester is?
An ordinary user
Why do black box testing?
Functional errors Errors in data structures or external database access Behavior of performance errors Initialization and termination errors Interface errors Incorrect or missing functions
Black box testing method is applicable to which software testing levels?
Integration testing
System testing
Acceptance testing
The higher the SW test level, the bigger and more complex the box, the more black box testing method comes into use
True
Some test design techniques in black box testing include equivalent class partitioning, boundary value analysis, and cause effect graphing
True
Equivalence class partitioning involves?
Dividing input values into valid and invalid partitions
Selecting representative values from each partition as test data
Boundary value analysis involves?
Determining boundaries for input values
Selecting values that are the boundaries and just inside/outside of the boundaries as test data
Cause Effect Graphing involves?
Identifying the cases (input conditions) and effects (output conditions)
Producing a cause-effect graph and generating test cases
Programs need to deal with various situations, some require unique program elements to handle them correctly?
True
Which of the following are testing risks?
Programmers might fail to recognize a particular situation as unique and needing unique handling
Programmers recognize that the situation is unique but might create unique elements of the program that handle the situation incorrectly
Programmers might fail to recognize or properly define these boundaries
Equivalence partitioning helps you recognize and test unique situations to ensure the programmer didn’t make such mistakes
True
In equivalence class partitioning there is one set of input values that maps to an output value and this set is called an___?
Equivalence class Equivalence partition
Equivalence class partitioning separates a specific functionality into distinct equivalence classes based on input values
True
Testers create equivalence classes by grouping input values that do something dissimilar
False
Equivalence classes enable testers to create tests which cover all or most parts of functionality, and avoid over-testing just one part
True
Equivalence classes can be applied at any level of testing and is often a good test design technique to use first.
True
Boundary value analysis is black box test design technique used to find errors at boundaries of input domain rather than finding those errors in the center of input
True
Equivalence Partitioning and Boundary value analysis are linked to each and can be used together at all levels of testing?
True
Interior values are?
Values which are not boundary values
Black box testing advantages include?
Tests are done from a user’s point of view and will help in exposing discrepancies in the specifications
Tests can be conducted by a body of testers independent from the developers, allowing for an objective perspective and the avoidance of developer-bias
Test cases can be designed as soon as the specifications are complete
Tester doesn’t need to know programming languages or how the software has been implemented
