+#### How to write a great visual test
+
+ - Generally speaking, you should avoid being "specific" in what you hope to find in the diff. Visual tests are best suited for finding unknown unknowns.
+ - These should only use functional expect statements to verify assumptions about the state
+in a test and not for functional verification of correctness. Visual tests are not supposed
+to "fail" on assertions. Instead, they should be used to detect changes between builds or branches.
+ - A great visual test controls for the variation inherent to working with time-based telemetry and clocks. We do our best to remove this variation by using `percyCSS` to ignore all possible time-based components. For more, please see our [percyCSS file](./.percy.ci.yml).
+ - Additionally, you should try the following:
+   - Use fixed-time mode of Open MCT
+   - Use the `createExampleTelemetryObject` appAction to source telemetry
+   - When using the `createDomainObjectWithDefaults` appAction, make sure to specify a `name` which is explicit to avoid the autogenerated name
+ - Very likely, your test will not need to compare changes on the tree. Keep it out of the comparison with the following
+   - `await page.goto('./#/browse/mine')` will go to the root of the main view with the tree collapsed.
+ - If you only want to compare changes on a specific component, use the /visual/component/ folder and limit the scope of the comparison to the object like so:
+   - ```
+      await percySnapshot(page, `Tree Pane w/ single level expanded (theme: ${theme})`, {
+            scope: treePane
+        });
