package testfiles

import "k8s.io/kubernetes/test/e2e/framework/testfiles"

Package testfiles provides a wrapper around various optional ways of retrieving additional files needed during a test run: - builtin bindata - filesystem access

Because it is a is self-contained package, it can be used by test/e2e/framework and test/e2e/manifest without creating a circular dependency.

Package Files ¶

testfiles.go

func AddFileSource ¶ Uses

func AddFileSource(filesource FileSource)

AddFileSource registers another provider for files that may be needed at runtime. Should be called during initialization of a test binary.

func Exists ¶ Uses

func Exists(filePath string) (bool, error)

Exists checks whether a file could be read. Unexpected errors are handled by calling the fail function, which then should abort the current test.

func Read ¶ Uses

func Read(filePath string) ([]byte, error)

Read tries to retrieve the desired file content from one of the registered file sources.

type BindataFileSource ¶ Uses

type BindataFileSource struct {
    Asset      func(string) ([]byte, error)
    AssetNames func() []string
}

BindataFileSource handles files stored in a package generated with bindata.

func (BindataFileSource) DescribeFiles ¶ Uses

func (b BindataFileSource) DescribeFiles() string

DescribeFiles explains about gobindata and then lists all available files.

func (BindataFileSource) ReadTestFile ¶ Uses

func (b BindataFileSource) ReadTestFile(filePath string) ([]byte, error)

ReadTestFile looks for an asset with the given path.

type FileSource ¶ Uses

type FileSource interface {
    // ReadTestFile retrieves the content of a file that gets maintained
    // alongside a test's source code. Files are identified by the
    // relative path inside the repository containing the tests, for
    // example "cluster/gce/upgrade.sh" inside kubernetes/kubernetes.
    //
    // When the file is not found, a nil slice is returned. An error is
    // returned for all fatal errors.
    ReadTestFile(filePath string) ([]byte, error)

    // DescribeFiles returns a multi-line description of which
    // files are available via this source. It is meant to be
    // used as part of the error message when a file cannot be
    // found.
    DescribeFiles() string
}

FileSource implements one way of retrieving test file content. For example, one file source could read from the original source code file tree, another from bindata compiled into a test executable.

type RootFileSource ¶ Uses

type RootFileSource struct {
    Root string
}

RootFileSource looks for files relative to a root directory.

func (RootFileSource) DescribeFiles ¶ Uses

func (r RootFileSource) DescribeFiles() string

DescribeFiles explains that it looks for files inside a certain root directory.

func (RootFileSource) ReadTestFile ¶ Uses

func (r RootFileSource) ReadTestFile(filePath string) ([]byte, error)

ReadTestFile looks for the file relative to the configured root directory. If the path is already absolute, for example in a test that has its own method of determining where files are, then the path will be used directly.
