TwitSplit

The product Tweeter allows users to post short messages limited to 50 characters each. Sometimes, users get excited and write messages longer than 50 characters. Instead of rejecting these messages, we would like to add a new feature that will split the message into parts and send multiple messages on the user's behalf, all of them meeting the 50 character requirement.

Android application versions:

Min SDK Version : 15 Target SDK Version: 28 Compile SDK Version: 28 Kotlin Version: 1.3.11 Gradle Version: 3.2.1

This Demo includes

1. Espresso Instrumental Test.
2. Business logic Unit Test.

#Note

Espresso doesn't work well with animations due to the visual state delays they introduce. You need to disable animations on your device. Firstly, enable developer options: Check https://developer.android.com/studio/debug/dev-options

• Open the Settings app.
• Scroll to the bottom and select About phone.
• Scroll to the bottom and tap Build number 7 times.
• Return to the previous screen to find Developer options near the bottom.

Access Developer Options from Settings app, and under the Drawing section, switch all of the following options to Animation Off:

• Window animation scale
• Transition animation scale
