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.
