Hooks

Hooks in SpecFlow allow you to execute setup and teardown logic before or after scenarios, features, or test runs. Hooks provide a way to perform common tasks such as setting up test data, initializing resources, or cleaning up after tests.


1. BeforeScenario Hook:

  • Executed before each scenario.
  • Useful for setting up test data or initializing resources.
C#
Copy
[BeforeScenario]
public void BeforeScenario()
{
    // Code to set up test data or initialize resources
}

2. AfterScenario Hook:

  • Executed after each scenario.
  • Useful for cleaning up resources or performing cleanup actions.
C#
Copy
[AfterScenario]
public void AfterScenario()
{
    // Code to clean up resources or perform cleanup actions
}

3. BeforeFeature Hook:

  • Executed before each feature.
  • Useful for setting up feature-specific data or initializing resources.
C#
Copy
[BeforeFeature]
public static void BeforeFeature()
{
    // Code to set up feature-specific data or initialize resources
}

4. AfterFeature Hook:

  • Executed after each feature.
  • Useful for cleaning up resources or performing cleanup actions related to a feature.
C#
Copy
[AfterFeature]
public static void AfterFeature()
{
    // Code to clean up resources or perform cleanup actions after a feature
}

5. BeforeTestRun Hook:

  • Executed once before the test run starts.
  • Useful for global setup tasks or initializing shared resources.
C#
Copy
[BeforeTestRun]
public static void BeforeTestRun()
{
    // Code to perform global setup tasks or initialize shared resources
}

6. AfterTestRun Hook:

  • Executed once after the test run completes.
  • Useful for global cleanup tasks or releasing shared resources.
C#
Copy
[AfterTestRun]
public static void AfterTestRun()
{
    // Code to perform global cleanup tasks or release shared resources
}

7. Tagged Hooks:

You can also apply hooks selectively based on tags using the same attributes with an additional parameter specifying the tag expression.

C#
Copy
[Before("@smoke")]
public void BeforeSmokeTests()
{
    // Code to set up environment before running smoke tests
}

In this example, the BeforeSmokeTests hook is executed only before scenarios tagged with @smoke.


Hooks provide a powerful mechanism to manage setup and teardown logic in your SpecFlow tests, helping to ensure that your tests run in a consistent and predictable environment.
