Fixes https://github.com/elastic/kibana/issues/149344 This PR migrates all plugins to packages automatically. It does this using `node scripts/lint_packages` to automatically migrate `kibana.json` files to `kibana.jsonc` files. By doing this automatically we can simplify many build and testing procedures to only support packages, and not both "packages" and "synthetic packages" (basically pointers to plugins). The majority of changes are in operations related code, so we'll be having operations review this before marking it ready for review. The vast majority of the code owners are simply pinged because we deleted all `kibana.json` files and replaced them with `kibana.jsonc` files, so we plan on leaving the PR ready-for-review for about 24 hours before merging (after feature freeze), assuming we don't have any blockers (especially from @elastic/kibana-core since there are a few core specific changes, though the majority were handled in #149370). --------- Co-authored-by: kibanamachine <42973632+kibanamachine@users.noreply.github.com> |

# Kibana Testing Library
The @kbn/test package provides ways to run tests. Currently only functional testing is provided by this library, with unit and other testing possibly added here.
## Functional Testing
### Dependencies
Functional testing methods exist in the `src/functional_tests` directory. They depend on the Functional Test Runner, which is found in [`{KIBANA_ROOT}/src/functional_test_runner`](../../src/functional_test_runner). Ideally libraries provided by kibana packages such as this one should not depend on kibana source code that lives in [`{KIBANA_ROOT}/src`](../../src). The goal is to start pulling test and development utilities out into packages so they can be used across Kibana and plugins. Accordingly the Functional Test Runner itself will be pulled out into a package (or part of a package), and this package's dependence on it will not be an issue.
### Exposed methods
#### `runTests(configPaths: Array<string>)`
For each config file specified in configPaths, starts Elasticsearch and Kibana once, runs tests specified in that config file, and shuts down Elasticsearch and Kibana once completed. (Repeats for every config file.)
`configPaths`: array of strings, each an absolute path to a config file that looks like [this](../../test/functional/config.base.js), following the config schema specified [here](../../src/functional_test_runner/lib/config/schema.js).
Internally the method that starts Elasticsearch comes from [kbn-es](../../packages/kbn-es).
#### `startServers(configPath: string)`
Starts Elasticsearch and Kibana servers given a specified config.
`configPath`: absolute path to a config file that looks like [this](../../test/functional/config.base.js), following the config schema specified [here](../../src/functional_test_runner/lib/config/schema.js).
Allows users to start another process to run just the tests while keeping the servers running with this method. Start servers _and_ run tests using the same config file ([see how](../../scripts/README.md)).
## Rationale
### Single config per setup
We think it makes sense to specify the tests to run along with the particular server configuration for Elasticsearch and Kibana servers, because the tests expect a particular configuration. For example, saml api integration tests expect certain xml files to exist in Elasticsearch's config directory, and certain saml specific options to be passed in via the command line (or alternatively via the `.yml` config file) to both Elasticsearch and Kibana. It makes sense to keep all these config options together with the list of test files.
### Multiple configs running in succession
We also think it makes sense to have a test runner intelligently (but simply) start servers, run tests, tear down servers, and repeat for each config, uninterrupted. There's nothing special about each kind of config that specifies running some set of functional tests against some kind of Elasticsearch/Kibana servers. There doesn't need to be a separate job to run each kind of setup/test/teardown. These can all be orchestrated sequentially via the current `runTests` implementation. This is how we envision tests to run on CI.
This inherently means that grouping test files in configs matters, such that a group of test files that depends on a particular server config appears together in that config's `testFiles` list. Given how quickly and easily we can start servers using [@kbn/es](../../packages/kbn-es), it should not impact performance to logically group tests by domain even if multiple groups of tests share the same server config. We can think about how to group test files together across domains when that time comes.
