Explanation:
When encountering a “connection refused” error while using WireMock, it typically means that the server is not reachable or not accepting connections. There are a few possible causes for this issue.
Possible Causes:
-
Port Number: Ensure that the specified port number for WireMock server is correct and not being used by any other process. By default, WireMock runs on port 8080.
-
Firewall: Check if there are any firewall rules or security settings blocking the connection to the WireMock server. Make sure that the necessary ports are open.
-
Server Configuration: Verify the server configuration to ensure that it is properly set up and running. This includes checking the server status, network settings, and any specific requirements for WireMock.
-
URL or Endpoint: Double-check the URL or endpoint you are using to send requests to the WireMock server. It should match the server location and port number.
Example Scenario:
Let’s say you have set up WireMock to run on port 8080, and you are trying to send a request to the following endpoint:
http://localhost:8080/api/users
If you encounter a “connection refused” error, you can perform the following checks:
-
Verify that WireMock is running and listening on the correct port (8080 in this case).
-
Check if there are any firewall rules blocking incoming connections to port 8080.
-
Make sure that the endpoint
http://localhost:8080/api/usersis correct and matches the WireMock server’s location and port.
