Kakao
Nice and simple DSL for Espresso in Kotlin
At Agoda, we have more than 1000 automated tests to ensure our application's quality and give our best experience to the user. All of them are written with Espresso from Google. Even though Espresso is working really well with our test, the code readability is quite low. Let's look at some of the examples of how we write the test. As Agoda developers, we want to improve not just our codebase quality, but also our implementation of tests as well. This is why we are introducing Kakao. The library will make you enjoy writing automated tests like you are drinking hot chocolate. Nice and simple DSL for Espresso in Kotlin. If you have custom Views in your tests and you want to create your own KView, we have KBaseView. Just extend this class and implement as many additional Action/Assertion interfaces as you want. You also need to override the constructors that you need. -

Anko consists of several parts that make up the complete framework, which are: Anko Commons: a lightweight library full of helpers for intents, dialogs, logging and so on. Anko Layouts: a fast and type-safe way to write dynamic Android layouts. Anko SQLite: a query DSL and parser collection for Android SQLite. Anko Coroutines: utilities based on the kotlinx.coroutines library. -

FlexboxLayout
Flexbox for Android
FlexboxLayout is a library project which brings the similar capabilities of CSS Flexible Box Layout Module to Android. Starting from 1.1.0, the library is expected to use with AndroidX. You should migrate to AndroidX if you use 1.1.0 or above. There are two ways of using Flexbox in your layout. The first one is FlexboxLayout that extends the ViewGroup like LinearLayout and RelativeLayout. You can specify the attributes from a layout XML. The second one is FlexboxLayoutManager that can be used within RecyclerView. The advantage of using FlexboxLayoutManager is that it recycles the views that go off the screen for reuse for the views that are appearing as the user scrolls instead of inflating every individual view, which consumes much less memory especially when the number of items contained in the Flexbox container is large. -
