Description

E.g., here:

https://github.com/uber/NullAway/blob/f1c302eea74a6535bc167af2ba79cb941858c4f2/nullaway/src/test/java/com/uber/nullaway/UnannotatedTests.java#L12-L12

We should call com.google.errorprone.CompilationTestHelper#addSourceLines instead and copy the relevant source into a text block, and then delete the separate source files. We can also remove any related @SuppressWarnings("deprecation") annotations.
