Functions

func AggregateStatus added in v0.54.0 

func AggregateStatus(useCustom bool, items ...Item) string

AggregateStatus defines the aggregation rules for status according to the following rules: If only pass/fail/unknown values are found, we apply very basic rules:

  • failure + * = failure
  • unknown + [pass|unknown] = unknown
  • empty list = unknown

If we find other values (e.g. from manual results typically) then we just combine/count them:

  • foo + bar = 'foo: 1, bar:1'

useCustom is specified rather than looking for custom values because different branches of the result tree may have/not have those values. So instead, we should look down the tree initially to decide.

func ClusterHealthFilePath added in v0.56.2 

func ClusterHealthFilePath() string

ClusterHealthFilePath returns the full path of the ClusterHealthFile

func ConfigFile 

func ConfigFile(version string) string

ConfigFile returns the path to the sonobuoy config file. This is not a method as it is used to determine the version of the archive.

func DiscoverVersion 

func DiscoverVersion(reader io.Reader) (string, error)

DiscoverVersion takes a Sonobuoy archive stream and extracts just the version of the archive.

func ExtractBytes 

func ExtractBytes(file string, path string, info os.FileInfo, buf *bytes.Buffer) error

ExtractBytes pulls out bytes into a buffer for any path matching file.

func ExtractConfig 

func ExtractConfig(path string, info os.FileInfo, conf *config.Config) error

ExtractConfig populates the config object regardless of version.

func ExtractFileIntoStruct 

func ExtractFileIntoStruct(file, path string, info os.FileInfo, object interface{}) error

ExtractFileIntoStruct is a helper for a common use case of extracting the contents of one file into the object. The first parameter is the desired file to extract, the second is the path being considered (by a WalkFn).

func ExtractIntoStruct 

func ExtractIntoStruct(predicate func(string) bool, path string, info os.FileInfo, object interface{}) error

ExtractIntoStruct takes a predicate function and some file information and decodes the contents of the file that matches the predicate into the interface passed in (generally a pointer to a struct/slice).

func FileOrAny(files []string) func(fPath string, info os.FileInfo) bool

func FileOrExtension added in v0.56.4 

func FileOrExtension(files []string, exts ...string) fileSelector

FileOrExtension returns a function which will return true for files which have the exact name of the file given or the given extension (if no file is given). If the filename given is empty, it will be ignored and the extension matching will be used. If "*" is passed as the extension all files will match.

func IsFailureStatus added in v0.54.0 

func IsFailureStatus(s string) bool

IsFailureStatus returns true if the status is any one of the failure modes (e.g. StatusFailed or StatusTimeout).

func IsTimeoutErr added in v0.54.0 

func IsTimeoutErr(i Item) bool

IsTimeoutErr is the snippet of logic that determines whether or not a given Item represents a timeout error (i.e. Sonobuoy timed out waiting for results).

func JUnitErrored added in v0.17.1

Types

type Item added in v0.15.1 

type Item struct {
	Name     string                 `json:"name" yaml:"name"`

func PostProcessPlugin added in v0.15.1 

func PostProcessPlugin(p plugin.Interface, dir string) (Item, []error)

PostProcessPlugin will inspect the files in the given directory (representing the location of the results directory for a sonobuoy run, not the plugin specific results directory). Based on the type of plugin results, it will record what tests passed/failed (if junit) or record what files were produced (if raw) and return that information in an Item object. All errors encountered are returned.

func ProcessDir added in v0.56.4 

func ProcessDir(p plugin.Interface, pluginDir, dir string, processor postProcessor, shouldProcessFile fileSelector) ([]Item, error)

ProcessDir will walk the files in a given directory, using the fileSelector function to choose which files to process with the postProcessor. The plugin directory is also passed in (e.g. plugins/e2e) in order to make filepaths relative to that directory.

func RawProcessFile added in v0.56.4 

func RawProcessFile(pluginDir, currentFile string) (Item, error)

RawProcessFile will return an Item object with the File value set to the path in question. If the file is unable to be stat'd then the status of the Item is StatusFailed (StatusPassed otherwise).

func (Item) Empty added in v0.15.1 

func (i Item) Empty() bool

Empty returns true if the Item is empty.

func (*Item) GetSubTreeByName added in v0.17.1 

func (i *Item) GetSubTreeByName(root string) *Item

GetSubTreeByName traverses the tree and returns a reference to the subtree whose root has the given name.

func (*Item) IsLeaf added in v0.56.4 

func (i *Item) IsLeaf() bool

IsLeaf returns true if the item has no sub-items (children). Typically refers to individual tests whereas non-leaf nodes more commonly refer to suites, nodes, or files rolled up from the individual tests.

func (*Item) Walk added in v0.56.4 

func (i *Item) Walk(fn func(*Item) error) error

Walk will do a depth-first traversal of the Item tree calling fn on each item. If an error is returned, traversal will stop.

type JUnitResult added in v0.55.1 

type JUnitResult struct {
	Suites JUnitTestSuites
}

JUnitResult is a wrapper around the suite[s] which enable results to be either a single suite or a collection of suites. For instance, e2e tests (which use the onsi/ginkgo reporter) report a single, top-level testsuite whereas other tools report a top-level testsuites object which may have 1+ testsuite children. Only one of the fields should be set, not both.

func (*JUnitResult) UnmarshalXML added in v0.55.1 

func (j *JUnitResult) UnmarshalXML(d *xml.Decoder, start xml.StartElement) error

UnmarshalXML will unmarshal the document into either the 'Suites' field of the JUnitResult. If a single testsuite is found (instead of a testsuites object) it is unmarshalled and then added into the set of JUnitResult.Suites.Suites

type JUnitSkipMessage added in v0.15.3 

type JUnitSkipMessage struct {
	Message string `xml:"message,attr"`

	SystemErr    string               `xml:"system-err,omitempty"`
}

JUnitTestCase is a single test case with its result.

func JUnitFilter added in v0.15.3 

func JUnitFilter(predicate func(testCase JUnitTestCase) bool, testSuite JUnitTestSuite) []JUnitTestCase

JUnitFilter keeps only the tests that match the predicate function.

	Suites  []JUnitTestSuite `xml:"testsuite"`
}

JUnitTestSuites is a collection of JUnit test suites.

type Reader 

type Reader struct {
	// Embedded reader assumed to be the *.tar.gz of results. If the tarball has
	// been extracted already, set the RootDir instead.
	io.Reader

	// RootDir, if set, instructs the reader to read as if the tarball of results
	// was extracted to the given root directory.
	RootDir string

	Version string
}

Reader holds a reader and a version. It uses the version to know where to find files within the archive.

func NewReaderFromBytes 

func NewReaderFromBytes(data []byte) (*Reader, error)

NewReaderFromBytes is a helper constructor that will discover the version of the archive and return a new Reader with the correct version already populated.

Example 
package main

import (
	"fmt"
	"os"

	"github.com/vmware-tanzu/sonobuoy/pkg/client/results"
)

func main() {
	path := "testdata/results-0.8.tar.gz"
	data, err := os.ReadFile(path)
	if err != nil {
		panic(err)
	}
	results, err := results.NewReaderFromBytes(data)
	if err != nil {
		panic(err)
	}
	fmt.Println(results.Version)
}

Output:

v0.8

func NewReaderFromDir added in v0.56.3 

func NewReaderFromDir(root string) *Reader

NewReaderFromDir creates a reader that will process the directory `root`. It is assumed this directory contains the extracted results. Note: Assumes 'VersionFifteen' of results, which is current as of this writing. Older versions probably don't even need support at this point.

func NewReaderWithVersion 

func NewReaderWithVersion(reader io.Reader, version string) *Reader

NewReaderWithVersion creates a results.Reader that interprets a results archive of the version passed in. Useful if the reader can be read only once and if the version of the data to read is known.

Example 
package main

import (
	"compress/gzip"
	"fmt"
	"os"

	"github.com/vmware-tanzu/sonobuoy/pkg/client/results"
)

func main() {
	path := "testdata/results-0.9.tar.gz"
	f, err := os.Open(path)
	if err != nil {
		panic(err)
	}
	reader, err := gzip.NewReader(f)
	if err != nil {
		panic(err)
	}
	r := results.NewReaderWithVersion(reader, results.VersionNine)
	fmt.Println(r.Version)
}

Output:

v0.9

func (*Reader) FileReader added in v0.15.1 

func (r *Reader) FileReader(filename string) (io.Reader, error)

FileReader returns a reader for a file in the archive.

func (*Reader) Metadata 

func (r *Reader) Metadata() string

func (*Reader) NamespacedResources 

func (r *Reader) NamespacedResources() string

NamespacedResources returns the path to the directory that contains information about namespaced Kubernetes resources.

func (*Reader) NodesFile 

func (r *Reader) NodesFile() string

NodesFile returns the path to the file that lists the nodes of the Kubernetes cluster.

func (*Reader) NonNamespacedResources 

func (r *Reader) NonNamespacedResources() string

NonNamespacedResources returns the path to the non-namespaced directory.

func (*Reader) PluginResultsItem added in v0.15.1 

func (r *Reader) PluginResultsItem(plugin string) (*Item, error)

PluginResultsItem returns the results file from the given plugin if found, error otherwise.

func (*Reader) PluginResultsReader added in v0.15.1

PluginResultsReader returns the results file from the given plugin if found, error otherwise.

func (*Reader) ReadVersion added in v0.56.3 

func (r *Reader) ReadVersion() (string, error)

func (*Reader) RunInfoFile added in v0.16.1 

func (r *Reader) RunInfoFile() string

RunInfoFile returns the path to the Sonobuoy RunInfo file which is extra metadata about the run. This was added in v0.16.1. The function will return the same string even for earlier versions where that file does not exist.

func (*Reader) ServerGroupsFile 

func (r *Reader) ServerGroupsFile() string

ServerGroupsFile returns the path to the groups the Kubernetes API supported at the time of the run.

func (*Reader) ServerVersionFile 

func (r *Reader) ServerVersionFile() string

ServerVersionFile is the location of the file that contains the Kubernetes version Sonobuoy ran on.

func (*Reader) WalkFiles 

func (r *Reader) WalkFiles(walkfn filepath.WalkFunc) error

WalkFiles walks all of the files in the archive. Processing stops at the first error. The error is returned except in the special case of errStopWalk which will stop processing but nil will be returned. In the case where the reader is based on a directory (not a tarball) ensure the WalkFuncs realize that the root directory will be part of the path.
