6. Special Interest Group level requirements
Kubernetes has defined
Testing Special Interest Groups
to make it easier for the community to write and run tests, and to contribute,
analyze and act upon test results. This chapter basically converts all the
requirements written in the previous chapters as mandatory Special Interest
Group Features. It enforces the overall requirements traceability to testing,
especially those offered for
End-to-End Testing
The reference conformance, for its part, lists all regexes matching the
following Features tabs defined here.
