Hi all,
I would like to use matchers with message...

I would like to use matchers with messages, but all the examples I see have exact values https://github.com/pact-foundation/pact-python/tree/master/examples/message .
Do matchers work with messages ? If so where can I find an example / documentation ?

There's a PR to change the current behaviour for this I believe, but something that was missing/unclear is you need to do this:
Copy code
with pact:
mock_slack(kwargs)
result = consumer(matchers.get_generated_values(event)).get_result()Mike Geeves
11/07/2022, 11:10 AMWhere the event has your matchers in, so something like
Copy code
TERM_ANY_EPIC = Term("^(audusd|eurcad|eurgbp|eurusd|gbpcad|gbpeur|gbpusd|usdcad|usdjpy)$", "audusd")
TERM_BUY_SELL = Term("^(BUY|SELL)$", "BUY")
event = {
"detail-type": "placeTrade",
"source": "ig-tracker",
"detail": {
"message": {
"epic": TERM_ANY_EPIC,
"trade_type": TERM_TRADE_TYPE,
"buysell": TERM_BUY_SELL,
}
},
}Mike Geeves
11/07/2022, 11:11 AMThe key bit being you need to make that
matchers.get_generated_values(event)Mike Geeves
