Apache camel mail mock

Apache Camel provides a mock endpoint that allows you to test and mock the behavior of a route without actually sending or receiving messages. This can be particularly useful when testing routes that involve sending or receiving emails using the Camel Mail component.

To use the mock endpoint with Camel Mail, you can follow these steps:

  1. Add the camel-mail dependency to your project's pom.xml file (if you're using Maven) or your project's build configuration file (if you're using Gradle or another build tool).
  2. Create a Camel route that uses the mail component to send or receive emails.
  3. Add a mock endpoint to the route, specifying the mock endpoint as the endpoint URI.
  4. Configure the mock endpoint to mimic the behavior you want to test. For example, you can set the mock endpoint to return a specific response or throw an exception.

Here's an example of how you might use the mock endpoint with Camel Mail:

from("direct:start")
 .to("mail:smtp://localhost:25?username=myuser&password=mypassword")
 .to("mock:myMockEndpoint");

from("direct:start")
 .to("mock:myMockEndpoint")
 .to("mail:smtp://localhost:25?username=myuser&password=mypassword");

In this example, the first route sends an email using the mail component and then routes the response to a mock endpoint called myMockEndpoint. The second route routes the input message to the same mock endpoint and then sends the response to the mail component.

You can then test the route by sending a message to the direct:start endpoint and verifying that the mock endpoint returns the expected response.
