It is very important that they understand each other. If one microservice expects something different, it can break everything.
Testing APIs is very important. If you want to learn this, you can join an API Testing Online Course. It helps you understand how to test APIs between microservices.
Now, let us learn how Pact helps with API testing. Pact is a very smart tool. It helps you make sure two microservices talk the right way.
What is Pact?
Pact is a tool for contract testing. It checks if two microservices agree on how to talk. One side is called the consumer. The other side is called the provider. The consumer says, “This is what I need.” The provider says, “I can give it to you.”
Pact checks that both sides match. This is called contract testing. It is like making sure two puzzle pieces fit together.
Why Use Pact?
Pact is good for many reasons. Here is why teams use it:
How Does Pact Work?
Pact works in three easy steps.
-
The consumer writes a test. It says what it wants from the provider.
-
Pact makes a contract file. This file tells what the consumer expects.
-
The provider runs tests to see if it meets the contract.
It is like writing a note. The consumer says what it wants. Then the provider checks the note and says, “Yes, I can do that.”
Pact in a Microservices Team
Let us see a simple example. There are two microservices. One is called "Order Service." The other is called "User Service."
The Order Service needs to ask the User Service for user info. It says, “I want the name and email of a user.” The User Service must send that.
If the User Service changes the format, the Order Service may break. Pact helps stop that. It will say, “Wait! Something changed!”

This shows why Pact is a smart tool for microservices.
Comparing Tools for Contract Testing
Let us see how Pact stands with other tools.
As you can see, Pact and Karate are very helpful. If you want to learn Karate, you can try the Karate API Online Course. It teaches you how to write tests in a simple way.
Learning More About API Testing
You can also get certified. Try Karate API Certification Training. It teaches how to write good tests and understand microservices better.
Conclusion
Pact is a useful tool. It helps teams write better APIs. It checks that both sides agree. This makes software safe and strong. Microservices grow fast. Bugs can grow too. Pact keeps them in check. It is a smart friend for all API developers. If you want to start your journey in API testing, begin with an API Testing Course. Learn how Pact works. Write your own tests. Make your microservices happy.
