Providing input to a component under test

This section covers the various ways to provide input to a component under test. It’s split into four sub sections:

• Passing parameters to components: This covers passing regular parameters, child content, cascading values, event callbacks, etc.
• Injecting services into components under test: This covers injecting services into components under test.
• Controlling the root render tree: This covers how to modify the root render tree in which components under tests are rendered.
• Configure 3rd party libraries for testing: This covers setting up third-party libraries in a bUnit testing scenario so that components under test that use them can be tested easily.
