描述

I was writing this scenario, where accidently I had written the a test case in two different class with same consumer and provider pair which is having Authorization header in the api request.

So when I publish the contract from one test class, contract was perfectly fine, but when I ran the second test class with exact same test case and publish the contract there was extra space coming in the authorization header.

Not sure why this happen?

研究方向
Investigate the contract merging logic in Pact JVM, specifically how interactions from multiple test classes with the same consumer provider pair are combined. The issue suggests that duplicate test cases cause an extra space in authorization headers. Look at the source files responsible for writing the pact file, possibly in the PactWriter or related classes. Check for any string concatenation or formatting that might introduce whitespace when interactions are appended.
