An Introduction to Paparazzi for Snapshot Testing

Snapshot testing allows you to ensure that your output continues to behave as expected. This is useful because as you revisit your code, some changes might cause something to break. When writing snapshot tests for Jetpack Compose components, you first need to have your code in a working state. Then generate a snapshot of its expected output given certain data. The snapshot tests are committed alongside the component. Paparazzi is an Android library you can use to create those snapshots for your apps in a simple and friendly way and compare them. One of the advantages this library has over its competitor <a href="https://github.com/pedrovgs/Shot" rel="noopener ugc nofollow" target="_blank">Shot</a> is that it doesn’t need an emulator to run the tests, it just runs in the unit test stage which is much faster. <h1>Set up</h1> Let’s begin the setup process for our first test! To get started, we need to make some changes to the root <code>build.gradle</code> file. First, we'll add the necessary dependency for Paparazzi and apply the plugin. The latest version available at the time of writing is 1.3.1. <a href="https://androidminded.com/an-introduction-to-paparazzi-for-snapshot-testing-b45a0be718bc">Visit Now</a>
