Overview

Package difftest implement test based on diffing serialized string output

User provides a function that get a input path and input string and returns a output path and output string. Content of output path and output string is compared and if there is a difference the test fails with a diff.

Test inputs are read from files matching Pattern from Path.

Note that output path can be the same as input which useful if the function implements some kind of transcript that includes both input and output.
