What is Pact?

It is a code-first tool for testing HTTP and message integrations using contract tests. Contract tests assert that inter-application messages conform to a shared understanding that is documented in a contract. Without contract testing, the only way to ensure that applications will work correctly together is by using expensive and brittle integration tests.
Pact is a tool in the Microservices Tools category of a tech stack.
Pact is an open source tool with 216 GitHub stars and 94 GitHub forks. Here’s a link to Pact's open source repository on GitHub
