## UPDATE
It has been removed the execution of the playwright tests on buildkite,
the execution will be re-enabled as soon as we are ready and as
described below in the PR, there are still steps pending to be done.
## Motivation
**Cypress is not performing well lately.**
* We have been facing significant performance issues with Cypress. For
instance, it takes a long time to open the visual interface and start
executing tests.
**Teams are finding it increasingly challenging to write new tests and
debug existing ones.**
* The time and effort required to create new tests or troubleshoot
existing ones have become burdensome.
**Concern about the impact this could have on our testing practices.**
* Lose motivation to write tests or, worse, skip writing crucial tests.
## Why Playwright?
* Compared to Cypress, Playwright seems to be known for its faster
execution times and lower resource consumption. What could have a
positive impact by having faster feedback during development and
execution of new tests as well as more efficient use of CI resources.
* Provides powerful debugging tools which can make easier to write,
debug and execute tests.
* Seems to provide the same capabilities we currently use in our Cypress
tests.
* Given Playwright's active development and backing by Microsoft, it is
likely to continue evolving rapidly, making it a safe long-term choice.
Considering all the above, Playwright seems to be a strong candidate to
replace Cypress and address all the issues we are facing lately
regarding UI test automation.
## Objective of this POC
To write in Playwright a couple of tests we currently have on Cypress to
check the performance of the tool as well as the development experience.
The tests selected have been:
-
[enable_risk_score_redirect.cy.ts](https://github.com/elastic/kibana/blob/main/x-pack/test/security_solution_cypress/cypress/e2e/entity_analytics/dashboards/enable_risk_score_redirect.cy.ts)
- Owned by Entity Analytics team and selected by its simplicity since it
does not need any special setup to be executed and is short.
-
[manual_rule_run.cy.ts](https://github.com/elastic/kibana/blob/main/x-pack/test/security_solution_cypress/cypress/e2e/detection_response/detection_engine/rule_gaps/manual_rule_run.cy.ts)
- Owned by Detection Engine team and selected because is short and adds
a bit more of complexity due to it needs of clean-up and setting up
initial data through the API.
## How to execute the tests
### Visual mode
- Navigate to: `x-pack/test/security_solution_playwright`
- Execute: `yarn open:ess` for ESS environment or `yarn open:serverless`
for serverless environment.
### Headless mode
- Navigate to: `x-pack/test/security_solution_playwright`
- Execute: `yarn run:ess` for ESS environment or `yarn run:serverless`
for serverless environment.
### From VScode
- Install `Playwright Test for VScode` extension by Microsoft
- Navigate to: `x-pack/test/security_solution_playwright`
- Execute: `yarn open:ess` for ESS environment or `yarn open:serverless`
for serverless environment.
- Open your IDE
- Click on the `Testing` icon
- On the `Test Explorer` click on the three dots to select the profile
you are going to execute `ess` or `serverless`
- Click on the test you want to execute or navigate to the spec file of
the test and execute it from the same spec.
## My experience
- Tests are way easier to implement than with Cypress.
- Playwright does not rely on chainable commands. Chainable commands on
Cypress can lead to confusing code.
- Without chainable commands, the flow of the tests is more explicit and
easier to understand.
- You can notice that the tool has been designed with Typescript in
mind.
- Is super easy to implement the Page Object Model pattern (POM).
- With POM the test code is clean and focused on "what" rather than
"how".
- Love the fact that you can execute the tests from the same IDE without
having to switch windows during test development.
- The visual mode execution gives you lots of information out of the
box.
## The scope of this PR
- Sets the initial infrastructure to write and execute tests with
Playwright.
- Has examples and set a basis about how to write tests using the POM.
- Allows the execution of the tests in ESS and serverless (just
stateless environment).
- Integrates the execution of the tests with buildkite.
## Pending to be done/investigate
- Proper readme
- How to split tests and PO between the different teams
- Good reports on CI
- Upload screenshots on CI
- Flaky test suite runner
- Complete the labeling
- Execution of the tests on MKI environments
## FAQ
**Can I start adding tests to playwright?**
Currently, you can explore and experiment with Playwright, but there is
still work pending to be done to make the tool officially usable.
**Why security engineering productivity is the owner of the playwright
folder?**
This is something temporary to make sure that good practices are
followed.

## Dearest Reviewers 👋
I've been working on this branch with @mistic and @tylersmalley and
we're really confident in these changes. Additionally, this changes code
in nearly every package in the repo so we don't plan to wait for reviews
to get in before merging this. If you'd like to have a concern
addressed, please feel free to leave a review, but assuming that nobody
raises a blocker in the next 24 hours we plan to merge this EOD pacific
tomorrow, 12/22.
We'll be paying close attention to any issues this causes after merging
and work on getting those fixed ASAP. 🚀
---
The operations team is not confident that we'll have the time to achieve
what we originally set out to accomplish by moving to Bazel with the
time and resources we have available. We have also bought ourselves some
headroom with improvements to babel-register, optimizer caching, and
typescript project structure.
In order to make sure we deliver packages as quickly as possible (many
teams really want them), with a usable and familiar developer
experience, this PR removes Bazel for building packages in favor of
using the same JIT transpilation we use for plugins.
Additionally, packages now use `kbn_references` (again, just copying the
dx from plugins to packages).
Because of the complex relationships between packages/plugins and in
order to prepare ourselves for automatic dependency detection tools we
plan to use in the future, this PR also introduces a "TS Project Linter"
which will validate that every tsconfig.json file meets a few
requirements:
1. the chain of base config files extended by each config includes
`tsconfig.base.json` and not `tsconfig.json`
1. the `include` config is used, and not `files`
2. the `exclude` config includes `target/**/*`
3. the `outDir` compiler option is specified as `target/types`
1. none of these compiler options are specified: `declaration`,
`declarationMap`, `emitDeclarationOnly`, `skipLibCheck`, `target`,
`paths`
4. all references to other packages/plugins use their pkg id, ie:
```js
// valid
{
"kbn_references": ["@kbn/core"]
}
// not valid
{
"kbn_references": [{ "path": "../../../src/core/tsconfig.json" }]
}
```
5. only packages/plugins which are imported somewhere in the ts code are
listed in `kbn_references`
This linter is not only validating all of the tsconfig.json files, but
it also will fix these config files to deal with just about any
violation that can be produced. Just run `node scripts/ts_project_linter
--fix` locally to apply these fixes, or let CI take care of
automatically fixing things and pushing the changes to your PR.
> **Example:** [`64e93e5`
(#146212)](64e93e5806)
When I merged main into my PR it included a change which removed the
`@kbn/core-injected-metadata-browser` package. After resolving the
conflicts I missed a few tsconfig files which included references to the
now removed package. The TS Project Linter identified that these
references were removed from the code and pushed a change to the PR to
remove them from the tsconfig.json files.
## No bazel? Does that mean no packages??
Nope! We're still doing packages but we're pretty sure now that we won't
be using Bazel to accomplish the 'distributed caching' and 'change-based
tasks' portions of the packages project.
This PR actually makes packages much easier to work with and will be
followed up with the bundling benefits described by the original
packages RFC. Then we'll work on documentation and advocacy for using
packages for any and all new code.
We're pretty confident that implementing distributed caching and
change-based tasks will be necessary in the future, but because of
recent improvements in the repo we think we can live without them for
**at least** a year.
## Wait, there are still BUILD.bazel files in the repo
Yes, there are still three webpack bundles which are built by Bazel: the
`@kbn/ui-shared-deps-npm` DLL, `@kbn/ui-shared-deps-src` externals, and
the `@kbn/monaco` workers. These three webpack bundles are still created
during bootstrap and remotely cached using bazel. The next phase of this
project is to figure out how to get the package bundling features
described in the RFC with the current optimizer, and we expect these
bundles to go away then. Until then any package that is used in those
three bundles still needs to have a BUILD.bazel file so that they can be
referenced by the remaining webpack builds.
