Beginning Cucumber and Behavior-driven Development

Beginning Cucumber and Behavior-driven Development

• start the course
• define the concepts behind ATDD, automated acceptance tests, and how Behavior-driven Development stems from this concept
• recognize the fundamental principles of BDD, process in which Cucumber supports and the benefits of using it
• describe the process in example mapping and understand the distinction between rules and examples
• demonstrate use cases using the application of Rules, Examples and Example Mapping
• identify how Cucumber works with features and steps and how it can be used with Ruby code
• list the available versions and the process of installing Cucumber with Ruby on Linux, Mac OSX, and Windows development machines, including HTTP proxy settings and additional gem packages
• install Cucumber with Ruby on a Mac OSX development machine
• identify Cucumber features and scenarios by writing feature files
• use regular expressions to create step definitions in Cucumber scenarios
• run Cucumber scenarios and show how to use the different formatters
• recognize how to add and manage assertions in Cucumber scenarios
• create a scenario that includes both features and steps, while exploring concepts in BDD design

Cucumber Steps and Scenario Development

Cucumber Steps and Scenario Development

• start the course
• describe the purpose of Gherkin in Test-driven Development and benefits along with the syntax used
• recognize the purpose of using features in Gherkin files and how to implement it to a project
• define steps and step definitions and how it is implemented in an example
• use features such as capture groups and wildcards and multiple arguments in Cucumber steps
• describe the available result states for a Cucumber scenario and provide examples of scenarios containing steps that lead to these results
• describe a background section in a Cucumber feature file to outline steps common to all scenarios
• use doc strings and data tables for data that doesn't fit on one line in Cucumber scenarios
• use scenario outlines to define steps for Cucumber scenarios
• use nest steps in Cucumber scenarios
• describe the use of transforms to remove duplication in Cucumber step definitions
• describe the Cucumber World object and refactor steps into Ruby helper methods that are added to the World
• describe the uses for directories and tagging Cucumber scenarios at feature and scenario level
• recognize the implementations of steps and step definitions, and how expressive scenarios work

Deep Dive Cucumber

Deep Dive Cucumber

• start the course
• group Cucumber features in subfolders and run a feature from a subfolder
• demonstrate how to filter Cucumber scenarios to run a subset using tags or lines
• use hooks in Cucumber scenarios
• demonstrate how to modify the default output from Cucumber using formatters such as progress, rerun, usage and stepdef, formatting to file, and use backtrace option
• demonstrate how to store Cucumber command line options in a YAML file and use the profile option to run them
• recognize handling of asynchronous systems in Cucumber scenarios
• recognize concepts including introducing ActiveRecord, refactor a Cucumber scenario to use data, and read and write data to a database
• use transactions and truncation to clean databases for Cucumber scenarios
• test REST APIs with Cucumber
• identify issues in Cucumber scenarios such as flickering scenarios; brittle and slow features; and unengaged stakeholders, identify underlying causes, and provide solutions
• recognize how Cucumber and Gherkin can be used with IOS, Android, PHP and many more platforms for tests
• create Cucumber scenarios for an ATM application
