Contract Testing: Practical Comparison of PACT, Spring Cloud
Too Long; Didn't Read
Contract testing is a method for verifying system integration by individually examining each application to ensure that contracts and interfaces adhere to the agreed-upon alignment. A mock integration point enables the validation of a component’s expected behavior without reliance on that component.
In the case of a large and intricate application, it may be necessary to establish an integration point trusted by multiple applications. This trusted integration point’s behaviors are validated by all dependent applications, preventing inadvertent or malicious changes from impacting the entire system.
Thus, a system can be constructed in which each component performs a specific task, safeguarding the system against accidental or malicious alterations to any of its components.
