Documentation

Overview

Package fstests provides generic integration tests for the Fs and Object interfaces.

These tests are concerned with the basic functionality of a backend. The tests in fs/sync and fs/operations tests more cornercases that these tests don't.

Functions

func NextMultipleOf

func NextMultipleOf(m fs.SizeSuffix) func(fs.SizeSuffix) fs.SizeSuffix

NextMultipleOf returns a function that can be used as a CeilChunkSize function. This function will return the next multiple of m that is equal or bigger than i. All values less or equal 0 will return 0.

func NextPowerOfTwo

func NextPowerOfTwo(i fs.SizeSuffix) fs.SizeSuffix

NextPowerOfTwo returns the current or next bigger power of two. All values less or equal 0 will return 0

func PutTestContents

func PutTestContents(ctx context.Context, t *testing.T, f fs.Fs, file *fstest.Item, contents string, check bool) (string, fs.Object)

PutTestContents puts file with given contents to the remote and checks it but unlike TestPutLarge doesn't remove

func Run

func Run(t *testing.T, opt *Opt)

Run runs the basic integration tests for a remote using the options passed in.

They are structured in a hierarchical way so that dependencies for the tests can be created.

For example some tests require the directory to be created - these are inside the "FsMkdir" test. Some tests require some tests files - these are inside the "FsPutFiles" test.

func TestPutLarge

func TestPutLarge(ctx context.Context, t *testing.T, f fs.Fs, file *fstest.Item)

TestPutLarge puts file to the remote, checks it and removes it on success.

Types

type ChunkedUploadConfig

type ChunkedUploadConfig struct {
	// Minimum allowed chunk size
	MinChunkSize fs.SizeSuffix
	// Maximum allowed chunk size, 0 is no limit
	MaxChunkSize fs.SizeSuffix
	// Rounds the given chunk size up to the next valid value
	// nil will disable rounding
	// e.g. the next power of 2
	CeilChunkSize func(fs.SizeSuffix) fs.SizeSuffix
	// More than one chunk is required on upload
	NeedMultipleChunks bool
}

ChunkedUploadConfig contains the values used by TestFsPutChunked to determine the limits of chunked uploading

type ExtraConfigItem

type ExtraConfigItem struct{ Name, Key, Value string }

ExtraConfigItem describes a config item for the tests

type InternalTester

type InternalTester interface {
	InternalTest(*testing.T)
}

InternalTester is an optional interface for Fs which allows to execute internal tests

This interface should be implemented in 'backend'_internal_test.go and not in 'backend'.go

type Opt

type Opt struct {
	RemoteName                   string
	NilObject                    fs.Object
	ExtraConfig                  []ExtraConfigItem
	SkipBadWindowsCharacters     bool     // skips unusable characters for windows if set
	SkipFsMatch                  bool     // if set skip exact matching of Fs value
	TiersToTest                  []string // List of tiers which can be tested in setTier test
	ChunkedUpload                ChunkedUploadConfig
	UnimplementableFsMethods     []string // List of methods which can't be implemented in this wrapping Fs
	UnimplementableObjectMethods []string // List of methods which can't be implemented in this wrapping Fs
	SkipFsCheckWrap              bool     // if set skip FsCheckWrap
	SkipObjectCheckWrap          bool     // if set skip ObjectCheckWrap
	SkipInvalidUTF8              bool     // if set skip invalid UTF-8 checks
}

Opt is options for Run

type SetUploadChunkSizer

type SetUploadChunkSizer interface {
	// Change the configured UploadChunkSize.
	// Will only be called while no transfer is in progress.
	SetUploadChunkSize(fs.SizeSuffix) (fs.SizeSuffix, error)
}

SetUploadChunkSizer is a test only interface to change the upload chunk size at runtime

type SetUploadCutoffer

type SetUploadCutoffer interface {
	// Change the configured UploadCutoff.
	// Will only be called while no transfer is in progress.
	SetUploadCutoff(fs.SizeSuffix) (fs.SizeSuffix, error)
}

SetUploadCutoffer is a test only interface to change the upload cutoff size at runtime
