 #### How to write a great visual test (TODO)
 
+#### How to write a great network test
+
+- Where possible, it is best to mock out third-party network activity to ensure we are testing application behavior of Open MCT.
+- It is best to be as specific as possible about the expected network request/response structures in creating your mocks.
+- Make sure to only mock requests which are relevant to the specific behavior being tested.
+- Where possible, network requests and responses should be treated in an order-agnostic manner, as the order in which certain requests/responses happen is dynamic and subject to change.
+
+Some examples of mocking network responses in regards to CouchDB can be found in our [couchdb.e2e.spec.js](./tests/functional/couchdb.e2e.spec.js) test file.
+
 ### Best Practices
 
 For now, our best practices exist as self-tested, living documentation in our [exampleTemplate.e2e.spec.js](./tests/framework/exampleTemplate.e2e.spec.js) file.
 
+For best practices with regards to mocking network responses, see our [couchdb.e2e.spec.js](./tests/functional/couchdb.e2e.spec.js) file.

 ### Tips & Tricks (TODO)
 
 The following contains a list of tips and tricks which don't exactly fit into a FAQ or Best Practices doc.
@@ -378,3 +400,23 @@ A single e2e test in Open MCT is extended to run:
 - Tests won't start because 'Error: <http://localhost:8080/># is already used...'
 This error will appear when running the tests locally. Sometimes, the webserver is left in an orphaned state and needs to be cleaned up. To clear up the orphaned webserver, execute the following from your Terminal:
 ```lsof -n -i4TCP:8080 | awk '{print$2}' | tail -1 | xargs kill -9```
+
+### Upgrading Playwright
+
+In order to upgrade from one version of Playwright to another, the version should be updated in several places in both `openmct` and `openmct-yamcs` repos. An easy way to identify these locations is to search for the current version in all files and find/replace.
+
+For reference, all of the locations where the version should be updated are listed below:
+
+#### **In `openmct`:**
+
+- `package.json`
+  - Both packages `@playwright/test` and `playwright-core` should be updated to the same target version.
+- `.circleci/config.yml`
+- `.github/workflows/e2e-couchdb.yml`
+- `.github/workflows/e2e-pr.yml`
+
+#### **In `openmct-yamcs`:**
+
+- `package.json`
+  - `@playwright/test` should be updated to the target version.
+- `.github/workflows/yamcs-quickstart-e2e.yml`
