cucumber when location

It looks like you're inquiring about using Cucumber for testing, particularly about the "When" step, which is a part of the Behavior-Driven Development (BDD) format. 

In Cucumber, the typical structure of a feature file looks like this:

```gherkin
Feature: Title of the feature
  In order to achieve something
  As a role
  I want some feature

  Scenario: Title of the scenario
    Given some precondition
    When some action is performed
    Then expect some result
```

**"When" Clause in Cucumber:**

The "When" step is used to describe an action that the user or system performs. This is usually the step where you define the specific interaction, event, or change that triggers the behavior you're testing.

### Example:

Here's an example scenario that tests a login feature using Cucumber:

```gherkin
Feature: User Login

  Scenario: Successful Login
    Given the user is on the login page
    When the user enters valid credentials
    And clicks the login button
    Then the user should be redirected to the dashboard
```

### Implementing the Step Definitions:

In your step definition file (usually written in Java, Ruby, JavaScript, etc.), you would implement the "When" steps like this:

```java
import io.cucumber.java.en.When;

public class LoginSteps {

    @When("the user enters valid credentials")
    public void enterValidCredentials() {
        // Code to input username and password
    }

    @When("clicks the login button")
    public void clickLoginButton() {
        // Code to click the login button
    }
}
```

### Conclusion:

The "When" clause is crucial for defining what action you want to test in your Cucumber scenarios. If you have a more specific context or question regarding the "when" location, please provide additional details, and I’d be happy to assist you further!
