As part of our move to continuous integration, we need a unit testing framework, in order to support our emerging Test-Driven-Development practice. By writing unit tests, we increase the confidence in our code and our build pipeline, and limit the number of issues when we make a code change.
Jest is used in all of our starter kits and reference architecture applications. We have very little configuration in the
package.json, and only use it to enable the coverage report and to blacklist the
node_modules folder, to increase test speed.
