Features

• New operators:
  • ErrorIs to check the data is an error and matches a wrapped error (uses errors.Is behind the scene),
  • First to find the first matching item of a slice or an array then compare its content,
  • Grep to reduce a slice or an array before comparing its content,
  • Last to find the last matching item of a slice or an array then compare its content,
  • Recv to read from a channel and test value;
• rework of JSON parsing:
  • introduction of raw strings,
  • literal \n, \r & \t accepted in strings,
  • $^Operator(params...) is possible,
  • "$^Operator(params...)" is possible,
  • Operator (without parenthesis) is possible,
  • accepts json.RawMessage;
• anchoring is now possible using td.A and td.Anchor, the generic versions of td.T.A and td.T.Anchor;
• td.Flatten now accepts an optional function to filter and/or transform the items before flattening them;
• *td.T gains Assert and Require methods, to be consistent with existing td.Assert and td.Require;
• introduce td.S function, to produce strings without needing fmt, shorter to write and following the same calling convention as test names (in other words auto-detecting Printf like format);
• new TestDeepInGotOK config to allow to test go-testdeep operators (is forbidden by default, but useful when go-testdeep is used outside golang tests) including td.T.TestDeepInGotOK method;
• tdhttp package:
  • tdhttp.TestAPI can now test HTTP responses as a whole (CmpResponse) as well as HTTP trailer (CmpTrailer),
  • tdhttp.PostForm and tdhttp.TestAPI.PostForm now also accept tdhttp.Q as data.

As usual: enjoy! :)
