UI tests with Compose

By Moro

Shrek, Compose functions are the future!

Shrek, do you know something about testing?

Shrek, let’s try to test a Composable function..

Shrek, are you here?

FINE…

Let’s test a composable function.

According to the spec, we need to add the dependencies…

• libs.versions.toml

• build.gradle.kts (app module)

Sherek, before you ask, I found a composable function to test…

It is an app bar. I want to test the following behaviors:

• There is a back event, the left arrow icon appears;
• There is no back event, the left arrow icon doesn’t appear.

FINE…

�Let’s do it.

​

We need to create a class defining the compose test rule.

Shrek, it is so beautiful. Is it a dream?

First test, we need to test if our Composable function is showing the button when there is a valid event…

Second test, we need to test if our Composable function hides the button when no event is passed…
