 Now the service dependency for `MyComponent` will be resolved through DI automatically.
 
-## Ignoring dependencies
-
-You might want to test a component that is composed of subcomponents with possible side-effects that you don't want to encounter during your test. In that case, you can prevent specific resources from being loaded during the test by calling `ignoreDependencies()`. This will prevent a module `<require>`d by a template
-from actually being loaded. Note that you need to provide the resolved module path,
-which may not be exactly the same as the path you used in `<require>`.

-```HTML A composed component - template
-<template>
-  <require from="./my-component"></require>
-
-  <my-component first-name="Alice"></my-component>
-
-  ${message}
-</template>
-```

-```JavaScript A composed component - View Model
-class MyParent {
-  message = "Hello from the parent!"
-}

 You can improve the readability of your complex views by using template literals in your tests -
