#1203 Support combining matching rules Issue created by mefellows In some cases, you need to apply multiple matchers to a field in order to properly validate it. Only Pact JVM currently supports this behaviour. The capability to combine matching rules will be enabled in the next release (

v0.4.19

), but the clients will need to update their DSLs to support it. Motivating Use Case From a request in slack. How might you write a matcher to check both the keys and values and the same time (use

eachKeyMatches

and

eachValueMatches

simultaneously):

enum Keys {
      One = "One",
      Two = "Two",
    }

    interface Value {
      min: number
      max: number
    }

    type R = Record<Keys, Value>
    const record: R  = {
      [Keys.One]:
        {
          min: 1,
          max: 2
        }
    }

  it("check record", async () => {
    messagePact
      .expectsToReceive("record")
      .withContent({
        // What need to write here to check type R ?
      })
  })
