UNDER DEVELOPMENT REQUIRES HEAVY TESTING

Why

• generics are used where possible
• meaningful diffs instead of bunch of lines(that is git-diff(actual, expected)) somewhere from values string representations, tree diffs are used instead, so you can see exactly where values do not match
• in unequal strings unprintable characters are escaped appropriately
• less dependencies than stretchr/testify
• fixtures api: use test resources and have them destroyed automatically:
  • env vars
  • file content
  • parsed json
  • temp file
  • temp dir
  • io.Reader contents
• power assert
• no api mirroring for asserting or require-ing and failing immediately after check
• golden files support
• pretty and colourful test output
• no Expect(ACTUAL).To(Equal(EXPECTED)) nonsense rewriting of simple ACTUAL == EXPECTED, just use assert.Equal(t, ACTUAL, EXPECTED) or assert.Assert(t, ACTUAL == EXPECTED) and see values used in case of failure (dark magic inside)
