"""
Runs a benchmark test against the given angular app using the given driver.
This rule was created with the intention of reducing the amount of
duplicate/boilderplate code, while also allowing you to be as verbose with
your app as you'd like. The goal being that if you just want to test a
simple component, the only thing you'd need to provide are the component
(via ng_srcs) and driver.
** USAGE NOTES **
(assets/styles): The default index.html imports a stylesheet named
"styles.css". This allows the use of the default index.html with a custom
stylesheet through the styles arg by providing either a styles.css in the
prefix directory or by providing a css binary named styles.css.
(assets): The default index.html expects that the root selector for
the benchmark app is "app-root".
(entry_point): The default entry_point expects a file named "app.module" to export
the root NgModule for the benchmark application. It also expects that the
root NgModule is named "AppModule".
TIP: The server is named `name + "_server"` so that you can view/debug the
app.
Args:
name: The name of the benchmark_test to be run
prefix: The relative path to the root directory of the benchmark app
driver: The ts driver for running the benchmark
driver_deps: Driver's dependencies
ng_srcs: All of the ts srcs for the angular app
ng_deps: Dependencies for the angular app
assets: Static files
styles: Stylesheets
entry_point: Main entry point for the angular app
entry_point_deps: Entry point's dependencies
