Expressive vs Pact: What are the differences?

Expressive: Build PHP microservices and web applications in minutes. Make your code flexible and robust, using the dependency injection container of your choice; Pact: Fast, easy and reliable testing for your APIs and microservices during development. 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.

Expressive and Pact belong to "Microservices Tools" category of the tech stack.

Some of the features offered by Expressive are:

  • PSR-15 and PSR-7
  • Routing
  • Dependency Injection Templating

On the other hand, Pact provides the following key features:

  • Support for JavaScript, JVM, .NET, Python, Go, Ruby, PHP, Swift and more
  • Get fast, reliable feedback on the compatibility of your integrations
  • Ensures all your services are compatible with each other before you deploy

Expressive and Pact are both open source tools. It seems that Expressive with 768 GitHub stars and 209 forks on GitHub has more adoption than Pact with 196 GitHub stars and 93 GitHub forks.
