By the end, you'll be equipped to write robust Gherkin scenarios that serve as the foundation for behavior-driven testing.
- Introduction to Specflow
- In this module, we will introduce you to SpecFlow, a powerful tool for implementing BDD in .NET projects. You'll learn why SpecFlow is essential for .NET developers, explore different types of SpecFlow tests, and get hands-on experience by installing and testing SpecFlow extensions in your preferred development environment.
- Getting Started with Specflow - Binding Steps
- In this module, we will guide you through the process of binding steps in SpecFlow, a crucial aspect of BDD. You'll start with a clean slate, create a SpecFlow class, and learn how to bind steps effectively. We will also cover how to resolve unbound steps, customize configurations, and run your tests to ensure everything is functioning correctly.
- Specflow - How Parameters Are Handled
- In this module, we will focus on how SpecFlow manages parameters within your test scenarios. You'll learn how to work with various types of parameters, including strings, integers, and datatables, and how to debug them to ensure they are handled correctly. This knowledge will enable you to write more dynamic and flexible BDD tests.
- Gherkin Datatables - Specflow Table Assist
- In this module, we will dive into handling Gherkin datatables using SpecFlow's Table Assist feature. You'll learn how to leverage helper methods to create instances and compare data within your tests, ensuring your scenarios are both accurate and efficient. We'll also cover how to fix common implementation issues to optimize your BDD workflow.
- Introduction to Specflow Hooks
- In this module, we will explore the concept of SpecFlow hooks, which allow you to execute specific actions at various points in your test run. You'll learn how to use hooks for logging, managing execution order, and passing context dependencies. We’ll also cover error handling within hooks, providing you with the tools to create more reliable and maintainable test suites.
- Splitting Features and Steps
- In this module, we will focus on effectively splitting and organizing features and steps within your SpecFlow projects. You'll learn how to refactor your code by separating step files, which can help in managing large test suites more efficiently. We will also discuss how to handle ignored and context-pending steps to maintain clarity and functionality in your tests.
- Sharing Data in Specflow - Context and Dependency Injection
- In this module, we will explore techniques for sharing data between SpecFlow scenarios using context and dependency injection. You'll learn about the SpecFlow context system, how to merge scenario context properties, and how to implement a base class approach with dependency injection. By the end, you'll have a comprehensive understanding of the different methods available and how to choose the best one for your testing needs.
- Advanced Specflow - Value Retrievers
- In this module, we will delve into advanced SpecFlow features focused on value retrievers. You'll learn how to work with built-in retrievers for DateTime and Enums and create custom retrievers for more complex data types. We’ll also address challenges like handling null values and parsing comma-separated lists, ensuring you have the tools to customize SpecFlow for any scenario.
- Step Argument Conversions
- In this module, we will explore the concept of step argument conversions in SpecFlow, which allows for the transformation of data passed into steps. You'll tackle a conversion challenge to solidify your understanding and learn how to handle complex data types using custom transformations, including IEnumerable table arguments. By the end, you'll be equipped to manage argument order precedence effectively to optimize your BDD scenarios.
- Advanced Specflow - Hooks and Scopes, Async
- In this module, we will explore advanced techniques in SpecFlow, focusing on hooks, scopes, and asynchronous step definitions. You'll learn how to write async step definitions to improve test efficiency and how to restrict hook scopes using various logical combinations like AND/OR at different levels. Additionally, we'll cover scoped bindings to ensure your tests remain well-organized and adaptable to changes.
- Running Tests with Specflow
- In this module, we will cover the different approaches for running SpecFlow tests, whether via the Test Explorer in Visual Studio or using command-line tools like dotnet test and vstest.console.
