© PureTesting 2008Testing Thought Leadership Extension to Noun and Verb Technique for writing better test cases
© PureTesting 2008Testing Thought Leadership Noun and Verb Technique
© PureTesting 2008Testing Thought Leadership ***Nouns and Verbs, Adjectives and Adverbs Some software systems exist to manipulate specific kinds of data The kinds of data sets are the nouns The manipulations are the verbs Adjectives and adverbs affect the manipulation Identify these items Write test in sentences Even trace coverage For example, an ATM system should Accept deposits Process withdrawals Answer inquiries Kinds of deposits, withdrawals, inquiries? Quickly? Securely? This test design technique comes from Elisabeth Hendrickson. ***Rex Black: Effective and Efficient Testing Course
© PureTesting 2008Testing Thought Leadership Extending Noun and Verb Technique Challenges in using the technique Often Requirements are not sufficiently detailed Extracting enough Noun and Verbs is difficult Writing complex scenario based tests from this technique is difficult The technique has been extended at PureTesting and used successfully Next few slides will present the extension with the help of an example…
© PureTesting 2008Testing Thought Leadership Extension Extract the nouns and verbs Use 5W1H to extract adjectives, adverbs and more information Use pre and post conditions to extract more nouns and verbs Enumerate properties of every noun Break down these properties to base elements Use boundary values, equivalence classes on the base elements Write tests for individual properties Combine operations (verbs) to write scenario based test cases of arbitrary complexity
© PureTesting 2008Testing Thought Leadership Applying the Extended Technique
© PureTesting 2008Testing Thought Leadership Example: File Open Requirement fragment: The application allows users to open supported files. With the given requirement fragment Very few meaningful test cases can be written using any test design technique Using out extension to noun & verb technique we plan to write extensive test cases
© PureTesting 2008Testing Thought Leadership Extracting the Nouns and Verbs The application allows users to open supported files Extracting Nouns Extracting Verbs Extracting Adjectives and Adverbs
© PureTesting 2008Testing Thought Leadership File open… Noun Look for properties of this noun Also ask What, Why, When, Where, Who, Which, How, How much/many Verb Look for properties of this verb Also ask What, Why, When, Where, Who, Which, How, How much/many
© PureTesting 2008Testing Thought Leadership File: Properties Enumerate all the properties of FILE File has Name Size Location Extension Metadata Creation date Accessing date Modification date State
© PureTesting 2008Testing Thought Leadership File: Properties Type Access Control Password protection Attributes Compression Support Encryption Support Creating application version
© PureTesting 2008Testing Thought Leadership Breaking Down the Properties: Name Name - is a string String - is a SEQUENCE of Characters Sequence = Length of string Characters are elements of some valid character set (THUS) Name Has a length Has a set of allowed characters And some characters are not allowed (/ or \ in file name on windows, spaces on Linux/Unix platforms)
© PureTesting 2008Testing Thought Leadership Applying Boundary Values Name/String Has a length (maximum and minimum) Has a set of allowed characters (valid equivalence class) And some characters are not allowed (invalid equivalence class)
© PureTesting 2008Testing Thought Leadership Dealing with the Verb(s)… Open how? Open in various ways double click drag and drop command line application menu open with … Open how many? Open one (minimum number of) file Many files Max. number of files that can be opened simultaneously… How fast How much time does it take to open the file?
© PureTesting 2008Testing Thought Leadership Some Simple Positive Test Cases Open a (supported) file Minimum size Maximum size Minimum name length Maximum name length Located on a network drive/web With and without appropriate extension Created using older/newer version of creating application Password protected Read-only …
© PureTesting 2008Testing Thought Leadership Some Simple Negative Tests Open file(s) of Unsupported type Changed extensions Corrupt file Invalid/non-existent name …
