Uniqueness as a Service in Wikipedia If one cannot go to Wikipedia for a first good look at a topic that is emerging in innovation 'spaces' that impact our species and societies profoundly, then the public will learn to merely 'Google' search or look elsewhere. ESaaS is an emerging topic in the 'greenovation' that is currently leading renewables development. I vote for keeping the article; it isn't overtly taxing our resources.

.Cucumber is a tool used by that supports (BDD). Central to the Cucumber BDD approach is its plain language parser called. It allows expected software behaviors to be specified in a logical language that customers can understand. As such, Cucumber allows the execution of feature documentation written in business-facing text. It is often used for testing other software. It runs automated written in a (BDD) style.Cucumber was originally written in the.
And was originally used exclusively for Ruby testing as a complement to the BDD framework. Cucumber now supports a variety of different programming languages through various implementations, including. The open source port of Cucumber in is called SpecFlow.
For example, and are software bridges that enable testing of and projects, respectively. Other implementations may simply leverage the parser while implementing the rest of the testing framework in the target language. Contents.Gherkin language Gherkin is the language that Cucumber uses to define test cases. It is designed to be non-technical and human readable, and collectively describes use cases relating to a software system.
The purpose behind Gherkin's syntax is to promote behavior-driven development practices across an entire development team, including business analysts and managers. It seeks to enforce firm, unambiguous requirements starting in the initial phases of requirements definition by business management and in other stages of the development lifecycle.In addition to providing a script for automated testing, Gherkin's natural language syntax is designed to provide simple documentation of the code under test.
Gherkin currently supports keywords in dozens of languages.Language Operations. # List available languagescucumber -i18n help # List a language's keywordscucumber -i18n $LANG Syntax Syntax is centered around a, similar to that of. The structure of a file is defined using whitespace and other control characters. # is used as the line-comment character, and can be placed anywhere in a file. Instructions are any non-empty and non-comment line.
They consist of a recognized Gherkin keyword followed by a string.All Gherkin files have the.feature file extension. They contain a single Feature definition for the system under test and are an executable test script. Features, Scenarios, and Steps Cucumber tests are divided into individual Features. These Features are subdivided into Scenarios, which are sequences of Steps.Features A feature is a that describes a specific function of the software being tested.
There are three parts to a Feature. The Feature: keyword. The Feature name (on the same line as the keyword). An optional description on the following linesExample Feature definition.
Feature: Withdraw Money from ATM A user with an account at a bank would like to withdraw money from an ATM. Provided he has a valid account and debit or credit card, he should be allowed to make the transaction. The ATM will tend the requested amount of money, return his card, and subtract amount of the withdrawal from the user's account. Scenario: Scenario 1 Given preconditions When actions Then results Scenario: Scenario 2.
Scenarios Each Feature is made of a collection of scenarios. A single scenario is a flow of events through the Feature being described and maps 1:1 with an executable test case for the system. Keeping with the example ATM withdrawal feature, a scenario might describe how a user requests money and what happens to their account. Scenario Outline: A user withdraws money from an ATM Given has a valid Credit or Debit card And their account balance is When they insert their card And withdraw Then the ATM should return And their account balance is Examples: Name OriginalBalance WithdrawalAmount NewBalance Eric 100 45 55 Gaurav 100 40 60 Ed 1000 200 800 At runtime the scenario is run against each row in the table. Column values are substituted for each of the named placeholders in the scenario.Steps The crux of a Scenario is defined by a sequence of Steps outlining the preconditions and flow of events that will take place. The first word of a step is a keyword, typically one of. Given - Describes the preconditions and initial state before the start of a test and allows for any pre-test setup that may occur.
When - Describes actions taken by a user during a test. Then - Describes the outcome resulting from actions taken in the When clauseOccasionally, the combination of Given-When-Then uses other keywords to define conjunctions. And - Logical and.
But - Logically the same as And, but used in the negative form. Scenario: A user attempts to withdraw more money than they have in their account Given John has a valid Credit or Debit card And his account balance is $ 20 When he inserts his card And withdraws $ 40 Then the ATM displays an error And returns his card But his balance remains $ 20 Tags Gherkin's Feature structure forces organisation. However, in cases where this default organisation is inconvenient or insufficient, Gherkin provides Tags. Tags are @-prefixed strings and can be placed before.
Feature. Scenario. Scenario Outline. ExamplesAn element can have multiple tags and inherits from parent elements.
Cucumber Step Definitions Steps in Gherkin's.feature files can be considered a method invocation. Before Cucumber can execute a step it must be told, via a step definition, how that step should be performed.Definitions are written in and conventionally filed under features/stepdefinitions/.steps.rb. Definitions start with the same keywords as their invocation (including Gherkin's full language support). Each definition takes two arguments. Either a or string with $variables. A block containing ruby code to executeExample using regular expressions.
Given '$name has a valid Credit or Debit card' do name # Ruby code end Hooks Hooks are Cucumber's way of allowing for setup to be performed prior to tests being run and teardown to be run afterwards. They are defined as executable Ruby blocks, similar to methods marked with @Before, @After annotations. Conventionally they are placed under support/, and are applied globally. Three basic types of hooks exist. Before - Runs before a scenario. After - Runs after a scenario.
Around - Assumes control and runs around a scenarioAdditional hooks include. BeforeStep. AfterStep. AfterConfiguration - Runs after Cucumber configuration and is passed an instance of the configurationBefore, After, and Around hooks optionally take a list of tags filtering scenarios that they apply to. A list of tags in the same string is treated as OR, while individual arguments are treated as AND; tags can be optionally negated by being preceded with.Example of a tagged before hook. Before ( '@ATM' ) do scenario # Ruby code endHooks are often used to maintain database state, typically by cleaning up prior to running a scenario. It is also possible to start and roll back a transaction using Before and After hooks, and many Cucumber extensions provide an @txn tag for such a purpose.Integrations and Implementations Non Ruby implementations of Cucumber exist for popular languages including, and Python.
Support also exists for integration testing frameworks. A complete list of implementations can be found on Cucumber. Cucumber has integrated testing tools working well with many configurations.
There are cucumber plugins for popular CI tools like and and also for IDEs like and.Below is an example of a step definition written for Java with Cucumber-JVM. $ cucumber -name logoutThe above command will run only those scenarios that contain the word 'logout'.It is also useful to be able to know what went wrong when a test fails. Cucumber makes it easy to catch bugs in the code with the -backtrace option.Cucumber can also be configured to ignore certain scenarios that have not been completed by marking them with the Work In Progress tag @wip.
When Cucumber is passed the -wip argument, Cucumber ignores scenarios with the @wip tag.References.
