In this blog, I will discuss one troubleshooting tip for Pact Mock Service not stopping, after Pact Contract test completed. The console shows a connection error, not directly related to the solution worked out for me. However, when I stopped Pact Mock Service manually, I was able to proceed with the Pact test.


Background

I am using the following code snippet for starting and stopping Mock Pact Server. I have selected Pact as it helps you to write an integration test without creating expensive infrastructure.

# Setting up pact
pact = Consumer('Consumer').has_pact_with(Provider('Provider'))
pact.start_service()
atexit.register(pact.stop_service)

I used the following steps to overcome this problem. However, note that this not a complete solution in the sense that, once you stop service manually, then you would not require to do it again. The non-stoppage of the Pact Mock Service may still occur. But you can apply the same solution once again.

2. Kill the process
3. Run the test


1. Check if any pact process is still running

Since pact-mock-service.rb is ruby file, you can simply type ps aux|grep "ruby" on the console. This will give all ruby process. You can locate this as shown in the blow screen. Get the pid for this process which will be used in next step.


2. Kill the proces

Run kill -9 pid to kill the pact process. You can use the pid which you have found in step 1.


3. Run the test

Now run the test which should be successful now.
