Assertion in Appium Studio

I’ve just started using Appium and I’m trying to find a way to add an assertion in order to check that the test has worked.

In android studio when you were recording there was an ‘Add assertion’ button but that doesn’t seem to exist for Appium. (or am I blind?)

Thanks!

??

I’d just export the code to Java and use JUnit/TestNG to assert values/elements etc.?
