+### Mapping CI CD jobs to local commands
+
+When you see the CI CD fail on jobs you may wonder three things
+- Do I have a bug in my code?
+- Is the test flaky?
+- Is there a bug in `main`?
+
+To answer these questions the following commands will give you confidence to locate the issue.
+
+#### Static Analysis
+
+Part of the CI CD pipeline performs static analysis on the code. Use the following commands to mimic the CI CD jobs.
+
+The following set of commands should get us closer to one and done commands to instantly retest issues.
+
+```
+yarn test-setup
+```
+
+> Gotcha, are packages up to date and is the wasm built?
+
+
+```
+yarn tsc
+yarn fmt-check
+yarn lint
+yarn test:unit:local
+```
+
+> Gotcha: Our unit tests have integration tests in them. You need to run a localhost server to run the unit tests.
+
+#### E2E Tests
+
+**Playwright Browser**
+
+These E2E tests run in a browser (without electron).
+There are tests that are skipped if they are ran in a windows OS or Linux OS. We can use playwright tags to implement test skipping.
+
+Breaking down the command `yarn test:playwright:browser:chrome:windows`
+- The application is `playwright`
+- The runtime is a `browser`
+- The specific `browser` is `chrome`
+- The test should run in a `windows` environment. It will skip tests that are broken or flaky in the windows OS.
+
+```
+yarn test:playwright:browser:chrome
+yarn test:playwright:browser:chrome:windows
+yarn test:playwright:browser:chrome:ubuntu
+```
+
+**Playwright Electron**
+
+These E2E tests run in electron. There are tests that are skipped if they are ran in a windows, linux, or macos environment. We can use playwright tags to implement test skipping.
+
+```
+yarn test:playwright:electron:local
+yarn test:playwright:electron:windows:local
+yarn test:playwright:electron:macos:local
+yarn test:playwright:electron:ubuntu:local
+```
+
+> Why does it say local? The CI CD commands that run in the pipeline cannot be ran locally. A single command will not properly setup the testing environment locally.
+
 #### Some notes on CI
 
 The tests are broken into snapshot tests and non-snapshot tests, and they run in that order, they automatically commit new snap shots, so if you see an image commit check it was an intended change. If we have non-determinism in the snapshots such that they are always committing new images, hopefully this annoyance makes us fix them asap, if you notice this happening let Kurt know. But for the odd occasion `git reset --hard HEAD~ && git push -f` is your friend.
