Getting started Specflow

Specflow is a BDD framework. Specflow integrates with Visual Studio.

What is BDDà

BDD or Behavior-driven development allows a developer to focus on testing the code based on the expected behaviour of the software which is easier for non technical stakeholders to understand.In BDD process the product owner or customer representatives species the behaviour they want to see in the system.BDD helps the developer collaborate with other stakeholders,including testers to define accurate unit tests focused on business needs.

BDD frameworks define acceptance criteria based on the given/when/then format.And it is usually done in very English like language ,which helps the domain experts to understand the implementation.

Given some initial context,

When an event occurs,

Then ensure some outcomes.

As the statement structure and syntax are formally documented, software tools like specflow can generate the code for developers to create test cases.

An example:

Given my bank account is in credit, and I made no withdrawals recently,

When I attempt to withdraw an amount less than my card's limit,

Then the withdrawal should complete without errors or warnings

Specflowà

   #As a BDD framework specflow aims at bridging the communication gap between domain experts and developers.

   #Specflow is available as a visual studio extension that we can install.

   #Specflow allows to write business readable tests feature file for the system that we are building.

   #A specflow feature file contains one or more test scenarios that describe the usage of the system.

   # Feature file and test scenarios within specflow are written in Gherkin business readable language.And Gherkin is available in multiple language such as English,French etc.

   # Each scenario is broken down into a number of individual steps.Each of these logical steps map to test code that we actually write to execute the system that we are building and checks that it’s doing the right thing.
