Micro Services- What are they?

Micro service are product of a software architectural style know as micro services architecture.

in this architecture, a single application is developed as a set of small service

Each services operates as its own process and communiates with the other services over a network

DOMAIN-DRIVEN DESIGN

Each service is thought of as a component

Organized around business capabilities and service model a real world domain. Responsibilities enforced via bounded contexts

• Loose coupling and high cohesion
• Continuous delivery — Extensive use of automation(testing,deployment etc)
• fast feedbcack on code quality
• provides confiedence that production software will work

End to End Test Guidelines

Consumer-Driven Test or contract testing

They only test:

Tools such as Pact, pacto and janis can be used to write contract test.

Another way to build this is to have 1 codebase and multiple pipeline.

Now there is a third option 1 code repository and 2 build pipeline per service and this is the recommended way to go.

With some scripting the cross-repo changes can resolve the issue.
