+=== Common things that break Angular unit tests ===
+== Changing DOM selectors ==
+If the test is expecting a certain DOM element, but you change the structure within an Angular template, the test might start failing.
+Note that you can use text of a button as a selector.  If the button text changes, you'll need to update the selector.
+To fix it: update the selector in the test.  Or perhaps the test can be made more general.
+== Adding a new service ==
+Adding a new service
+To fix it: add a mock for the new service in the test.  Or even better, consider if you can simplify or refactor the component so that it does not need many different services.
+== Lifecycle/timing issues ==
+Interacting with anything asynchronous (especially grid and combobox) requires some care!
+To fix it: You may be able to add a setTimeout.  Or use Angular's fakeAsync and tick.
