"overwrite" and "merge" result in no pact files being written. When using "update", it just gives an empty log, but the pact files are written:

As far as I can see

<PactfileWriteMode>

is used in two places,

<MessageConsumerOptions>

and in

<MessageProviderOptions>

. It doesn't seem to work in the first case though. How we are currently doing is that before we run consumer tests we remove all the previous pact files and generate new files. Then we publish them to the broker. After that we run the provider tests which verify against the broker pact files published. pact-foundation/pact-js
