v1.11.0

New features

• JSON, SubJSONOf and SuperJSONOf operators:
  • Now:

    td.JSON(`{"foo": $1}`, td.Between(12, 34))
    td.JSON(`{"foo": Between($1, $2)}`, 12, 34)

    act the same way. Since v1.10.1 rework, the second was not working as expected.
    At the same time:

    td.JSON(`{"foo": Between(12, 34, $1)}`, td.BoundsOutIn)

    now works as expected. It was rejected before,
  • int_lit & float_lit numbers, as defined in go specification, are now accepted in JSON, allowing, for example, to embed hexadecimal numbers in expected JSON;
• Between operator accepts time.Duration as TO when FROM is a time.Time;
• Between, Gt, Gte, Lt and Lte operators:
  • now handle values implementing Compare or Less methods:
    Compare and/or Less methods signatures follow:

    func (a T) Less(b T) bool   // returns true if a < b
    func (a T) Compare(b T) int // returns -1 if a < b, 1 if a > b, 0 if a == b

    for example, the new go1.18 net/netip.Addr implements both,
  • failure reports display numbers as elsewhere,
  • some docs have been fixed;
• Smuggle can now cast values, allowing such things:

  // A string containing JSON
  got := `{ "foo": 123 }`
  td.Cmp(t, got, td.Smuggle(json.RawMessage{}, td.JSON(`{"foo":123}`))
  // or
  td.Cmp(t, got, td.Smuggle((json.RawMessage)(nil), td.JSON(`{"foo":123}`))

• in report failures, the stack trace was displayed if it contained at least 2 levels. Now it is also displayed if it contains one level BUT the source file path contains a directory. It helps to localize quickly the errors in large repositories;
• td.T gains 3 new methods to log with a stack trace: LogTrace, ErrorTrace and FatalTrace;
• handle go1.17 []T → *[n]T convertibility edge case;
• in failure reports (float64) type is now omitted (like (int) and (bool) already were), but the value always contains a "." (except if ±Inf, NaN or with exponent) to distinguish them from int.

Fixes

• Contains: slice in slice search didn't work at end of slice;
• JSON, SubJSONOf and SuperJSONOf operators panicked when using All+JSON-operator+embeddedOp+$1;
• anchoring 2 slices at the same time didn't work.

Miscellaneous

• CI build:
  • now uses install-go.pl v3.0, so tip test is very fast most of the time,
  • golangci-lint upgraded to v1.43.0,
  • uses bidichk linter;
• //go:build line added when // +build was already present, since go1.17 changes;
• //nolint: pragmas uniformized.

And happy new year!
