/**
|
|
* A test runner that was added to start Robolectric with our custom configuration for use in unit tests.
|
|
*
|
|
* This class is now deprecated as the configuration is set by robolectric.properties instead.
|
|
* You should only use Robolectric when necessary because it non-trivially increases test duration.
|
|
*
|
|
* usage:
|
|
* ```
|
|
* @RunWith(FenixRobolectricTestRunner::class)
|
|
* class ExampleUnitTest {
|
|
* ```
|
|
*
|
|
* There were three common test runners before this patch:
|
|
* 1. The default (@RunWith not specified) = JUnit4
|
|
* 2. @RunWith(RobolectricTestRunner::class) = JUnit4 with support for the Android framework via Robolectric
|
|
* 3. @RunWith(AndroidJUnit4::class) = JUnit4 with support for the Android framework. This currently
|
|
* delegates to Robolectric but is presumably generically named so that it can support different
|
|
* implementations in the future. The name creates confusion on over the difference between this and
|
|
* JUnit without any Android support (1).
|
|
*
|
|
* We chose the name RobolectricTestRunner because we want folks to know they're starting Robolectric
|
|
* because it increases test runtime. Furthermore, the naming of 3) is unclear so we didn't want to
|
|
* use that name.
|
|
*
|
|
* As a result, new tests should use RobolectricTestRunner.
