Crema

Set of utilities to extend the espresso testing framework

Word origin: Crema is the foam that makes espresso delicious.

How to get Crema

STEP 1: Download crema.jar from Releases and paste to your lib folder.

STEP 2: Next, you need to add a test compile dependency to your app's build.gradle

dependencies {
    // Testing-only dependencies
    androidTestCompile 'com.android.support.test:runner:0.5'
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
    androidTestCompile files('libs/crema-1.0.jar')
}

STEP 3: Finally, add EspressoPlus.* matchers in your test.

import static com.checkdroid.crema.EspressoPlus.*;

What does Crema get you

With Crema, we want to bring a library of new matchers and assertions to espresso.

As of now, crema has the following:

• XPath Matchers: Crema has 2 implementations of xPath Matchers
• withXPath(String xPath)
• withXPath2(String xPath)
• Taking screenshots in tests: Saves screenshots as /sdcard/{filename}_{timestamp}.png
• takeScreenshot() - default file name is package name
• takeScreenshot(String filename)
• takeScreenshot(boolean timestamp) - timestamp is not added if false
• takeScreenshot(String file, boolean addTimestamp)
• Fetchers
• TextFetcher class to get the text contained in a particular node
• ViewTreeFetcher class to get the espresso view tree (different from UIAutomator view tree)
• More coming soon..
