How deeply does Google Anthos in Action cover unit test?

Defines isolated testing and its CI role, but stops short of detailing test design, execution mechanics, or assertion strategies.

Unit test

As explained in Google Anthos in Action

Unit testing is the practice of testing an isolated software unit, such as a function, class, or module, against expected behavior.

A unit test checks an isolated software unit, such as a function, class, module, or business-domain service, against expected behavior. In modernization work, continuous integration runs unit tests to provide rapid feedback and expose problems early. section 16.1

Unit testing supports modernization by:

Identifying and fixing application problems faster through automated checks in the build pipeline. section 16.1
Building and testing a single business-domain service in isolation after capabilities are decoupled into smaller services. section 16.1
