General global test utilities.

Regarding test/test_*.go and its test.With* functions

Test helpers like test.WithTestDatabase and test.WithTestServer require usage of a closure, as these functions automatically manage the setup and teardown (e.g. server shutdown, db connection drop) for your testcase.

Other pkgs don't have this requirement (e.g. the initialization code for test.NewTestMailer which covers the setup for the mailer mock), thus, please use this With* convention incl. closure only when it makes sense.

Regarding test/fixtures.go

This are your global db test fixtures, that are only available while testing. However, feel free to setup specialized fixtures per package if required (e.g. just initialize an additional IntegreSQL template).

Regarding test/helper_*.go

Please use this convention to specify test only utility functions.

Regarding snapshot testing

Golden files can be created by using the Snapshoter.Save(t TestingT, data ...interface{}) method. The snapshot can be configured to force an update, use a different replacer function or to set a different file location and suffix for the snaphot.

A snapshot can be updated by either calling the Update(true) method, or by using the global override by setting the environment variable TEST_UPDATE_GOLDEN to true. To update all snapshots the call might look like this: TEST_UPDATE_GOLDEN=true make test.

testdata and . or _ prefixed files

Note that Go will ignore directories or files that begin with "." or "_", so you have more flexibility in terms of how you name your test data directory.

Go build ignores directory named testdata. The Go tool will ignore any directory in your $GOPATH that starts with a period, an underscore, or matches the word testdata When go test runs, it sets current directory as package directory

The main definition which fixtures are available through Fixtures(). Mind the declaration order! The fields get inserted exactly in the order they are declared.

func Fixtures 

func Fixtures() FixtureMap

Fixtures returns a function wrapping our fixtures, which tests are allowed to manipulate. Each test (which may run concurrently) receives a fresh copy, preventing side effects between test runs.

type GenericArrayPayload 

type GenericArrayPayload []interface{}

func (GenericArrayPayload) Reader 

func (g GenericArrayPayload) Reader(t *testing.T) *bytes.Reader

type GenericPayload 

type GenericPayload map[string]interface{}

func (GenericPayload) Reader 

func (g GenericPayload) Reader(t *testing.T) *bytes.Reader

type Insertable 

type Insertable interface {
	Insert(ctx context.Context, exec boil.ContextExecutor, columns boil.Columns) error
}

Insertable represents a common interface for all model instances so they may be inserted via the Inserts() func

func Inserts 

func Inserts() []Insertable

Inserts defines the order in which the fixtures will be inserted into the test database

type TestingT 

type TestingT interface {
	Cleanup(func())
	Error(args ...interface{})
	Errorf(format string, args ...interface{})
	Fail()
	FailNow()
	Failed() bool
	Fatal(args ...interface{})
	Fatalf(format string, args ...interface{})
	Helper()
	Log(args ...interface{})
	Logf(format string, args ...interface{})
	Name() string
	Skip(args ...interface{})
	SkipNow()
	Skipf(format string, args ...interface{})
	Skipped() bool
	TempDir() string
}

TestingT is used to generate a mock of testing.T to enable testing of helper methods which are using assert/require Inspired by: https://github.com/uber-go/zap/blob/master/zaptest/testingt_test.go, commit 5b0fd114dcc089875ee61dfad3617c3a43c2e93e
