 * In the [Cypress Test Runner](https://docs.cypress.io/guides/core-concepts/test-runner), you'll Cypress automatically visit the page.  This first test will succeed, as all you are doing is making sure the _page exists_.
 * From here, you can use the [Selector Playground](https://docs.cypress.io/guides/core-concepts/test-runner#Selector-Playground) in the Cypress Test Runner window to determine how to tell Cypress to interact with a specific HTML element on that page.
     * Most commands start by telling Cypress to [get()](https://docs.cypress.io/api/commands/get) a specific element, using a CSS or jQuery style selector
+      * It's generally best not to rely on attributes like `class` and `id` in tests, as those are likely to change later on. Instead, you can add a `data-test` attribute to makes it clear that it's required for a test. 
     * Cypress can then do actions like [click()](https://docs.cypress.io/api/commands/click) an element, or [type()](https://docs.cypress.io/api/commands/type) text in an input field, etc.
+      * When running with server-side rendering enabled, the client first receives HTML without the JS; only once the page is rendered client-side do some elements (e.g. a button that toggles a Bootstrap dropdown) become fully interactive. This can trip up Cypress in some cases as it may try to `click` or `type` in an element that's not fully loaded yet, causing tests to fail. 
+      * To work around this issue, define the attributes you use for Cypress selectors as `[attr.data-test]="'button' | ngBrowserOnly"`. This will only show the attribute in CSR HTML, forcing Cypress to wait until CSR is complete before interacting with the element.
     * Cypress can also validate that something occurs, using [should()](https://docs.cypress.io/api/commands/should) assertions.
 * Any time you save your test file, the Cypress Test Runner will reload & rerun it. This allows you can see your results quickly as you write the tests & correct any broken tests rapidly.
 * Cypress also has a great guide on [writing your first test](https://on.cypress.io/writing-first-test) with much more info. Keep in mind, while the examples in the Cypress docs often involve Javascript files (.js), the same examples will work in our Typescript (.ts) e2e tests.
