Declare go 1.18 in go.mod - Update make commands * Declare generic checker types * Type checker providers using Checker[T] interface * Update checker providers interfaces - Disable code generation for providers interfaces - Update providers interfaces manually * Update checker providers unit tests * Update package check examples * Update package checkconv - Type checkconv.Assert using check.Checker[T] interface - Type checkconv.Cast using check.Checker[T] interface * Update testx runners - Add type parameters to ValueRunner - Use new type check.Checker[T] - Update tests and examples * Update temporary CI config - Disable jobs: gen, lint - Disable test coverage - Add setup step: Install gotip * Replace all occurrences of interface{} -> any --- .circleci/config.yml | 169 ++++++++++---------- .golangci.yml | 6 +- Makefile | 8 +- check/README.md | 8 +- check/check.go | 14 +- check/check2.go | 36 +++++ check/checkers.go | 8 +- check/example_custom_closures_test.go | 15 +- check/example_custom_test.go | 14 +- check/example_custom_unknown_test.go | 2 +- check/example_newintchecker_test.go | 7 +- check/gen.go | 4 +- check/providers.go | 193 +++++++++++------------ check/providers_base.go | 32 ++-- check/providers_base_internal_test.go | 16 +- check/providers_bool.go | 6 +- check/providers_bool_test.go | 32 +--- check/providers_bytes.go | 62 ++++---- check/providers_bytes_test.go | 74 +++------ check/providers_context.go | 20 +-- check/providers_context_test.go | 45 ++---- check/providers_duration.go | 24 +-- check/providers_duration_test.go | 50 ++---- check/providers_float64.go | 48 +++--- check/providers_float64_test.go | 70 +++----- check/providers_httpheader.go | 34 ++-- check/providers_httpheader_test.go | 50 ++---- check/providers_httprequest.go | 46 +++--- check/providers_httprequest_test.go | 50 ++---- check/providers_httpresponse.go | 56 +++---- check/providers_httpresponse_test.go | 54 ++----- check/providers_int.go | 48 +++--- check/providers_int_test.go | 70 +++----- check/providers_map.go | 62 ++++---- check/providers_map_test.go | 82 ++++------ check/providers_slice.go | 84 +++++----- check/providers_slice_test.go | 68 +++----- check/providers_string.go | 46 +++--- check/providers_string_test.go | 56 ++----- check/providers_struct.go | 28 ++-- check/providers_struct_test.go | 36 ++--- check/providers_test.go | 50 ++++-- check/providers_value.go | 52 +++--- check/providers_value_test.go | 60 +++---- checkconv/README.md | 16 +- checkconv/assert.go | 175 ++++++++++---------- checkconv/assert_test.go | 12 +- checkconv/cast.go | 12 +- checkconv/cast_test.go | 8 +- checkconv/checkconv_test.go | 40 ++--- checkconv/gen.go | 2 +- checkconv/ischecker.go | 4 +- checkconv/ischecker_test.go | 2 +- example_httphandler_test.go | 2 +- example_table_test.go | 6 +- example_value_test.go | 11 +- go.mod | 2 +- internal/fmtexpl/fmtexpl.go | 4 +- internal/gen/gen.go | 8 +- internal/gen/templates/assert.gotmpl | 36 +++-- internal/gen/templates/check.gotmpl | 4 +- internal/gen/templates/checkers.gotmpl | 2 +- internal/gen/types.go | 2 +- internal/reflectutil/func.go | 6 +- internal/reflectutil/func_test.go | 2 +- internal/reflectutil/reflectutil.go | 14 +- internal/reflectutil/reflectutil_test.go | 16 +- internal/testutil/testutil.go | 2 +- runner.go | 6 +- runner_httphandler.go | 6 +- runner_httphandler_test.go | 6 +- runner_table.go | 22 +-- runner_table_test.go | 20 +-- runner_test.go | 6 +- runner_value.go | 36 +++-- runner_value_test.go | 12 +- testx.go | 18 +-- 77 files changed, 1164 insertions(+), 1351 deletions(-) create mode 100644 check/check2.go diff --git a/.circleci/config.yml b/.circleci/config.yml index 5ada2f0..2dce924 100644 --- a/.circleci/config.yml +++ b/.circleci/config.yml @@ -17,110 +17,115 @@ commands: name: Install dependencies command: | go mod download + -

- -Package `checkconv` provides conversion utilities to convert any typed checker to a `check.ValueChecker` - -## Table of contents - -- [Why convert checkers](#why-convert-checkers) -- [Available functions](#from-functions) - - [`From` functions](#from-functions) - - [`Assert` functions](#assert-functions) - - [`Cast` functions](#cast-functions) -- [`Assert` vs `Cast`](#assert-vs-cast) - - [Should I use `Assert` or `Cast`](#should-i-use-assert-or-cast) - -## Why convert checkers - -Some runners from `testx` have methods that require generic checkers as parameters, -such as `testx.ValueRunner.Pass`: - -```go -type ValueRunner interface { - // Pass adds checkers on the tested value. - Pass(checkers ...check.ValueChecker) ValueRunner - // ... -} -``` - -These methods theorically accept any checker, either from package `check` -or locally implemented with custom types. - -However, without a language support for generic types, -package `check` cannot provide a generic checker interface because -they have distinct signatures for method `Pass(got T) bool`. - -```go -// What we need: -type GenericChecker[T any] interface { - Pass(got T) bool - Explainer -} - -// What we have: -type IntChecker interface { - Pass(got int) bool - Explainer -} -type StringChecker interface { - Pass(got string) bool - Explainer -} -``` - -As a consequence, there is no way to combine `IntChecker` and `StringChecker` -into a generic `Checker` interface. -For that reason, we use `check.ValueChecker` checker (checker on type `any`), -because it can wrap any checker type. - -That's what this package provides: functions to wrap any typed checker -into a generic `check.ValueChecker`. - -## Available functions - -### `From` functions - -`From` functions return a generic `check.ValueChecker` that wraps -the input `check.Checker`. - -It is typically used for runners that expect a `check.ValueRunner` -when one wants to use a typed checker: - -```go -testx. - Value(42). - // Pass expects a check.ValueChecker - Pass( - // We use check.IntChecker then we convert it using checkconv.FromInt. - checkconv.FromInt(check.Int.InRange(41, 43)), - ). - Run(t) -) -``` - -### Assert functions - -- `Assert(checker any) check.ValueChecker` -- `AssertMany(checkers ...any) []check.ValueChecker` - -Assert functions basically return `From(inputChecker)` -if that `From` function exists for the input checker. -Else, it panics. - -```go -testx. - Value(42). - // Pass expects a check.ValueChecker - Pass( - // We use check.IntChecker then we convert it using checkconv.Assert. - checkconv.Assert(check.Int.InRange(41, 43)), - ). - Run(t) -) -``` - -Alternatively, `AssertMany` can be used to convert several checkers at once: - -```go -testx. - Value(42). - // Pass expects a check.ValueChecker - Pass( - // We use several check.IntChecker then we convert them - // using checkconv.AssertMany. - checkconv.AssertMany( - check.Int.InRange(41, 43), - check.Int.Not(-1), - check.Int.GTE(99), - )..., - ). - Run(t) -) -``` - -### Cast functions - -- `Cast(checker any) (check.ValueChecker, bool)` -- `CastMany(checkers ...any) []check.ValueChecker` - -Cast functions serve the same purpose as Assert functions: -they wrap the given checker in a `check.ValueChecker`. -The difference is that it works with _any_ type that implement -a checker interface (`Pass(T) bool` and `Explain(string, any string`) -while Assert functions are restricted to the types defined in package `check`. - -### `Assert` vs `Cast` - -There is a fundamental difference between `Assert` and `Cast` implementations: - -- `Assert` uses `From` functions that rely on type assertion - to wrap the input checker: - ```go - func Assert(knownChecker any) check.ValueChecker { - switch c := knownChecker.(type) { - case check.StringChecker: - return FromString(c) - // ... - default: - // Assert panics if the input checker is not defined in package check. - log.Panic("assert from unknown checker type") - return nil - } - } - - func FromString(c check.StringChecker) check.ValueChecker { - return check.NewValueChecker( - func(got any) bool { return c.Pass(got.(string)) }, - c.Explain, // ^^^^^^^^^^^^^^^^^^^ got is safely asserted - ) - } - ``` - This is faster, but requires the input checker to implement one of the native - `check.Checker` interfaces. - -- `Cast` uses **reflection** to determinate whether a checker is valid and call -its methods in the resulting checker. As a consequence it is slower than -`Assert`, however it remains the only way to wrap a `check.ValueChecker` -around a full-fledged custom checker that performs checks on types that are not -defined in package `check`. - -#### Should I use `Assert` or `Cast` - -- Use `Assert`/`From` to convert any checker from package `check`, - or custom checkers that implement any `check.Checker` interface - (see [provided checkers](../check/README.md#provided-checkers)). - - ```go - checkconv.AssertMany( - check.Int.Range(41, 43), // satisfies check.IntChecker - check.NewIntChecker(isEven, explainIsEven), // satisfies check.IntChecker - myCustomIntChecker, // satisfies check.IntChecker - ) - ``` - -- Use `Cast` to convert any checker on types that are not defined - in package `check`. - - ```go - checkconv.CastMany( - myCustomComplex128Checker, - myCustomUserChecker, - ) - ``` \ No newline at end of file diff --git a/checkconv/assert.go b/checkconv/assert.go deleted file mode 100644 index 9ba93e2..0000000 --- a/checkconv/assert.go +++ /dev/null @@ -1,169 +0,0 @@ -// Code generated by go generate ./...; DO NOT EDIT -// Last generated on 31 Oct 21 17:02 UTC - -// Package checkconv provides functions to convert typed checkers -// into generic ones. -// -// TODO: delete package checkconv -package checkconv - -import ( - "context" - "net/http" - "time" - - "github.com/drykit-go/testx/check" -) - - -// FromBool returns a check.Checker[any] that wraps the given -// check.Checker[bool], so it can be used as a generic checker. -func FromBool(c check.Checker[bool]) check.Checker[any] { - return check.NewChecker( - func(got any) bool { return c.Pass(got.(bool)) }, - c.Explain, - ) -} - - -// FromBytes returns a check.Checker[any] that wraps the given -// check.Checker[[]byte], so it can be used as a generic checker. -func FromBytes(c check.Checker[[]byte]) check.Checker[any] { - return check.NewChecker( - func(got any) bool { return c.Pass(got.([]byte)) }, - c.Explain, - ) -} - - -// FromString returns a check.Checker[any] that wraps the given -// check.Checker[string], so it can be used as a generic checker. -func FromString(c check.Checker[string]) check.Checker[any] { - return check.NewChecker( - func(got any) bool { return c.Pass(got.(string)) }, - c.Explain, - ) -} - - -// FromInt returns a check.Checker[any] that wraps the given -// check.Checker[int], so it can be used as a generic checker. -func FromInt(c check.Checker[int]) check.Checker[any] { - return check.NewChecker( - func(got any) bool { return c.Pass(got.(int)) }, - c.Explain, - ) -} - - -// FromFloat64 returns a check.Checker[any] that wraps the given -// check.Checker[float64], so it can be used as a generic checker. -func FromFloat64(c check.Checker[float64]) check.Checker[any] { - return check.NewChecker( - func(got any) bool { return c.Pass(got.(float64)) }, - c.Explain, - ) -} - - -// FromDuration returns a check.Checker[any] that wraps the given -// check.Checker[time.Duration], so it can be used as a generic checker. -func FromDuration(c check.Checker[time.Duration]) check.Checker[any] { - return check.NewChecker( - func(got any) bool { return c.Pass(got.(time.Duration)) }, - c.Explain, - ) -} - - -// FromContext returns a check.Checker[any] that wraps the given -// check.Checker[context.Context], so it can be used as a generic checker. -func FromContext(c check.Checker[context.Context]) check.Checker[any] { - return check.NewChecker( - func(got any) bool { return c.Pass(got.(context.Context)) }, - c.Explain, - ) -} - - -// FromHTTPHeader returns a check.Checker[any] that wraps the given -// check.Checker[http.Header], so it can be used as a generic checker. -func FromHTTPHeader(c check.Checker[http.Header]) check.Checker[any] { - return check.NewChecker( - func(got any) bool { return c.Pass(got.(http.Header)) }, - c.Explain, - ) -} - - -// FromHTTPRequest returns a check.Checker[any] that wraps the given -// check.Checker[*http.Request], so it can be used as a generic checker. -func FromHTTPRequest(c check.Checker[*http.Request]) check.Checker[any] { - return check.NewChecker( - func(got any) bool { return c.Pass(got.(*http.Request)) }, - c.Explain, - ) -} - - -// FromHTTPResponse returns a check.Checker[any] that wraps the given -// check.Checker[*http.Response], so it can be used as a generic checker. -func FromHTTPResponse(c check.Checker[*http.Response]) check.Checker[any] { - return check.NewChecker( - func(got any) bool { return c.Pass(got.(*http.Response)) }, - c.Explain, - ) -} - - - - -// Assert returns a check.Checker[any] that wraps the given -// check.Checker[T]. -// -// It panics if checker is not a known checker type.
