Specflow Tricks: apart from basics

This is short guide that describes how to use some Specflow amazing features

• Data tables transformation
  • Direct table parsing
  • Using Specflow Assist library to create certain instances and set of instances
  • Using Specflow Assist library and customize instance newly created with StepsArgumentTransformation attribute
• Extensions for Feature and Scenario contexts to manage test data
• Creating your own test data context and share it between multiple steps binding classes: use built-in Specflow BoDi dependency injection container to setup data context (shared dependency instance) and use constructor injection of shared dependency in binding classes
• Strings formatting is steps:
  • inline formatting with placeholders passed from Scenario-level data
  • inline formatting with placeholders passed from code-level data
• Tags
  • Filtering usage: Using tags to restrict Hook method binding (Before, After). Using multiple tags in Hook methods
  • Categorizing usage: Using tags to mark
    • Feature
    • Scenario
    • Scenario Example
• Just some nice things about Specflow
  • Usage of multiple binding attributes on method in order to bing it to several steps
  • Usage of Scope attribute in order to restrict method binding to some concrete Feature/Scenario step
