If you want to use the latest versions of the libraries, here what you must do.

compile is going to be replaced with implementation soon. Compiler gives warnings regarding that so you should change it.

Testing-only dependancies should be changed from androidTestCompile to androidTestImplementation

com.google.android.gms:play-services-appindexing:x.x.x is obsolete as it is replaced with com.google.firebase:firebase-appindexing:x.x.x where x.x.x is the version you need.

Here is a changed version that uses the latest libraries. Anything with the $ in it is a String value that you can change if a new version comes out for those.

`dependencies {

def espresso_version = "3.0.2"
def android_support_version = "27.1.1"
def android_support_test_version = "1.0.2"
def firebase_version = "16.0.1"

implementation "com.android.support:design:$android_support_version"
implementation "com.android.support:support-annotations:$android_support_version"
implementation "com.google.firebase:firebase-appindexing:$firebase_version"
implementation "com.android.support.test.espresso:espresso-idling-resource:$espresso_version"

// Testing-only dependencies
androidTestImplementation "com.android.support:support-annotations:$android_support_version"
androidTestImplementation "com.android.support.test.espresso:espresso-core:$espresso_version"
androidTestImplementation "com.android.support.test.espresso:espresso-intents:$espresso_version"
androidTestImplementation "com.android.support.test:rules:$android_support_test_version"
androidTestImplementation "com.android.support.test:runner:$android_support_test_version"

}`

Change compileSdkVersion 25 to compileSdkVersion 27

The static imports would be highlighted in red on the InstrumentedTest java files. Just delete the static imports and add each one. Can alt + enter on items you have your cursor on that are needing imports.

I'm trying to do the first exercise. I added maven repository in the build.gradle of the project, without this I can't compile the project:

allprojects {
    repositories {
        maven {
            url 'https://maven.google.com'
        }
        jcenter()
    }
}

Then I added the dependecies in the build.gradle of the app:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "com.example.android.teatime"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile 'com.android.support:design:25.1.0'
    compile 'com.android.support:support-annotations:25.1.0'
    compile 'com.google.android.gms:play-services-appindexing:9.8.0'

    // DONE (4) Add the required Espresso UI Testing dependencies
    // Testing-only dependencies
    androidTestCompile 'com.android.support:support-annotations:25.1.0'
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
}

But AndroidJUnit4 and ActivityTestRule are not recognized and I can't import them.

My Android Studio:
Android Studio 4.0

Upon adding libs to gradle I am getting cannot resolve AndroidJUnit4 error.

on running the test on an emulator, a error
android.support.test.espresso.PerformException: Error performing 'load adapter data' on view 'with id: com.example.android.teatime:id/tea_grid_view'.
occurs.

In the method clickDecrementButton_ChangesQuantityAndCost() we should increment first the quantity to "1" to test that the decrement button works!. Comments updated accordingly:

    @Test
    public void clickDecrementButton_ChangesQuantityAndCost() {

    // Check the initial quantity variable is zero
    onView((withId(R.id.quantity_text_view))).check(matches(withText("0")));

    // Click on increment button
    onView((withId(R.id.increment_button)))
        .perform(click());

    // Click on decrement button
    onView((withId(R.id.decrement_button)))
            .perform(click());

    // Verify that the decrement button decreases the quantity by 1
    onView(withId(R.id.quantity_text_view)).check(matches(withText("0")));

    // Verify that the decrement button also decreases the total cost from $5.00 to $0.00
    onView(withId(R.id.cost_text_view)).check(matches(withText("$0.00")));

}

Loading large images the resizing them by the system either throws OOM error or make the scrolling too slow.

To fix that move the images (tea images) to a new folder named drawable-nodpi instead of locating them inside drawable, in this case the images will be loaded with the same original size without resizing them to go along with device's density.

https://stackoverflow.com/questions/47078005/why-is-espressos-registeridlingresources-deprecated-and-what-replaces-it

In TODO (6) Instead of:
Espresso.registerIdlingResources(mIdlingResource);
use:
IdlingRegistry.getInstance().register(mIdlingResource);

In TODO (8) instead of:
Espresso.unregisterIdlingResources(mIdlingResource);
use:
IdlingRegistry.getInstance().unregister(mIdlingResource);

In the Gradle build dependencies,
compile 'com.google.android.gms:play-services-appindexing:9.8.0' shows it is deprecated, please update the project to use the firebase 10.0.0 or above,

compile 'com.google.firebase:firebase-appindexing:11.2.2' solves it

At the initial state hard coded $ currency (R.string.initial_cost) is used
After the increase/decrease btn pressed NumberFormat.getCurrencyInstance().format() is used which it can changes the currency not just the quantity.

In TESP.04-Solution-AddIdlingResourceMenuActivityTest, MenuActivityScreenTest doesn't pass any more!!!
Also, in MenuActivity, there is a comment saying "We call ImageDownloader.downloadImage from onStart or onResume instead of in onCreate to ensure there is enougth time to register IdlingResource if the download is done too early (i.e. in onCreate)". This comment makes a feeling that mIdlingResource should be assigned and registered @before registerIdlingResource() before calling ImageDownloader.downloadImage() in onStart(). And in this case (similar to IdlingResourceSample), there would be no need to call getIdlingResource() in onCreate(). However, when using Logs, it is clear that all of onCreate(), onStart(), and onResume() in MenuActivity are actually called before @before registerIdlingResource() in IdlingResourceMenuActivityTest. That's why we must call getIdlingResource() in onCreate() to initialize mIdlingResource before using it in ImageDownloader.downloadImage().

Initially the activity layout displays a currency symbol $ though once the button is pushed it displays the symbol of my region, the € symbol.

It seems system dependent to me. The test case may need to be adapted to make it run successfully.

Hi guys, while trying to follow up with espresso lesson repos, I found the following

1- Warning:Conflict with dependency 'com.android.support:support-annotations'. Resolved versions for app (25.1.0) and test app (23.1.1) differ. See http://g.co/androidstudio/app-test-app-conflict for details.
"I guess my build tools issue but wasn't solved after changing the build number "

and I can't really get what's the reason for the following issues;

Besides android studio can't recognize testing classes

Testing the first exercice on my Samsung S4, I have an out of memory error.
Is exist a way to increase the memory limit ?

After following all the instructions, I am getting above exception while Running the test

IdlingResourceMenuActivityTest
at com.example.android.teatime.IdlingResourceMenuActivityTest.idlingResourceTest(IdlingResourceMenuActivityTest.java:40)

And Line 40 of the code wrote exactly as you've guided or written in your sample

onData(anything()).inAdapterView(withId(R.id.tea_grid_view)).atPosition(0).perform(click());

can you guide me solve this issue?

Thanks

Update All versions and Dependencies to Latest Versions

Update dependencies by hover over them

After all these steps gradle should successfully build
And only Code Errors remains which u can easily handle by importing all the necessary imports

The first TODO here is bad.
// TODO (1) Add annotation to specify AndroidJUnitRunner class as the default test runner

It should be
// COMPLETE (1) Add annotation to specify AndroidJUnit4 class as the default test runner

This is true for both the second and third exercises.

Hi guys, just a matter of suggestion I would recommend bring steps like add resource gradle dependency to one of the first TODO steps. The reason I am saying that is because for those not familiar with the IDE or even are not that good yet at predicting problems, walking along the steps with sintax problems popping up your code is not cool.

For instance exercise 4:

https://github.com/udacity/AdvancedAndroid_TeaTime/tree/TESP.04-Exercise-AddIdlingResourceMenuActivityTest

You can't get your code compiled at step 3 and 4 until your reach the step 9.

I know that is a very silly situation, but let's think as very beginner person.

What's wrong? This is what I get when I run the solution code:
