UI-less on-device test: Setup

- [Instructor] Great, now we're on our way…to read from an asset folder into a recipe store.…How do we test it?…We cannot use JVN unit test…because the recipe store class…requires a context to read the assets.…We need to use an instrumentation test.…Remember, an instrumentation test…runs on a device,…and, therefore, have access to Android classes.…To create an instrumentation test…we will add espresso as a dependency.…

Go to app slash build.gradle.…In the dependency block in line 24…we will add another dependency.…This time we will use an Android test dependency,…so Android test compile.…And then we are going to use…com.android.support.test.espresso:…espresso-core:…2.2.2.…

We are going to actually exclude something…from this dependency.…Exclude group:…com.android.support,…module:…support-annotations.…We add this exclude line for espresso library…so that we can avoid version conflict…with the support annotations…that is included by addcompat in line 23.…

Click on sync now to run a gradle sync.…With all the dependencies taken care of,…
