// The example is in Groovy but this probably works for any kind of logging for an app/test running in IDEA
// The important part is the template: "ComparisonFailure\nexpected:<{?}> but was:<{?}>"
// This works for multi-line values for each '?', which is why being able to use in-ide diff is so nice
def expected = ...
def actual = ...
// do your custom comparison, then if fails throw:
String msg = "ComparisonFailure\nexpected:<{${expected}}> but was:<{${actual}}>"
throw new AssertionError(msg)
