Use Truth to compare proto to string

Question

Is there a way to use Google Truth to compare a protobuff to a string? I am hoping to find something that looks like this:

assertThat(myProto).isEqualToString("a: 1\n b:2")

Answer 1

Truth provides an extension for protocol buffer assertions, which is probably what you should use. Asserting on a message's string format is going to be brittle, and failures will be harder to understand.

That said you certainly can do what you're asking:

assertThat(myProto.toString()).isEqualTo("a: 1\n b:2");
