+## Testing with cypress
+
+These notes setup cypress and run tests. These notes are likely to change.
+
+- One time step: **Outside** the Apollo dev container
+  [install cypress](https://docs.cypress.io/guides/getting-started/installing-cypress).
+  E.g. on your OS terminal (not vscode) run:
+
+```
+yarn --cwd packages/jbrowse-plugin-apollo add cypress --dev
+yarn --cwd packages/jbrowse-plugin-apollo add cypress-mongodb --dev
+```
+
+Add these lines to the `packageExtensions` section of `.yarnrc.yml`:
+
+```
+  cypress-mongodb@*:
+    dependencies:
+      bson: "*"
+```
+
+Then run `yarn` again.
+
+---
+
+- Start [jbrowse](https://github.com/GMOD/jbrowse-components): You may want to
+  pull the latest code to be consistent with the GitHub workflow
+
+```
+cd /path/to/jbrowse-components
+git pull
+yarn --cwd products/jbrowse-web start
+```
+
+- Start Apollo server. Within the docker container (_i.e_ within vscode) and in
+  distinct terminals run:
+
+```
+yarn --cwd packages/apollo-shared start
+```
+
+```
+yarn --cwd packages/apollo-collaboration-server run cypress:start
+```
+
+```
+yarn --cwd packages/jbrowse-plugin-apollo start
+```
+
+If above you change the name fo the test database (`apolloTestDb`), change
+accordingly in `commands.ts`
+
+- Open cypress in the testing directory, _i.e._ where yo have the relevant
+  `package.json`. Typically (again outside the dev container/vscode):
+
+```
+yarn --cwd packages/jbrowse-plugin-apollo run cypress open
+```
+
+- For end-to-end testing, click "E2E Testing" `->` Chrome `->`
+  `Start E2E Testing`. Click on one of the available test scripts.
