Variables

var InvalidDependencies = errors.BoolTag{Key: errors.NewTagKey("invalid test dependencies")}

InvalidDependencies tag indicates that an error was caused because swarming dependencies for a task were invalid.

Functions

func ValidateDependencies

func ValidateDependencies(ctx context.Context, c trservice.Client, argsGenerator ArgsGenerator) ([]types.TaskDimKeyVal, error)

ValidateDependencies checks whether this test has dependencies satisfied by VMLab or at least one Skylab bot.

Returns nil if the dependencies are valid and satisfiable. Returns an error tagged with InvalidDependencies tag if provided dependencies are invalid. Optionally returns a map of the unsatisfiable dependencies.

Errors encountered in dependency validation are returned as generic errors.

Types

type ArgsGenerator

type ArgsGenerator interface {
	// Generate arguments for swarming task or buildbucket build.
	GenerateArgs(ctx context.Context) (request.Args, error)
	// Check the internal consistency of of the generator arguments.
	CheckConsistency() error
}

ArgsGenerator is used to generate arguments to buildbucket / swarming.

type ArgsModifier

type ArgsModifier interface {
	ModifyArgs(ctx context.Context, args request.Args) error
}

ArgsModifier is used to inject modifications to

type Build

type Build struct {
	Args request.Args

	TaskReference trservice.TaskReference
	// contains filtered or unexported fields
}

Build represents an individual test_runner build.

func NewBuild

func NewBuild(ctx context.Context, c trservice.Client, argsGenerator ArgsGenerator, argsModifier ArgsModifier) (*Build, error)

NewBuild creates a new test_runner build.

func NewBuildForTesting

func NewBuildForTesting(swarmingTaskID, url string) *Build

NewBuildForTesting allows other packages to create builds objects with arbitrary fields for testing.

func (*Build) Completed

func (b *Build) Completed() bool

Completed returns whether the current build is complete.

func (*Build) Refresh

func (b *Build) Refresh(ctx context.Context, c trservice.Client) error

Refresh fetches and updates the state of the given build from the test_runner service.

func (*Build) Result

func (b *Build) Result() *steps.ExecuteResponse_TaskResult

Result constructs a TaskResults out of the last known state of the Build.

In order to get the latest result, FetchResult needs to be called first.

func (*Build) Retry

func (b *Build) Retry(ctx context.Context, c trservice.Client, retryNumber int32) (*Build, error)

Retry creates a new build to retry the current build.

Retry does not check whether the current build is complete.

func (*Build) Running

func (b *Build) Running() bool

func (*Build) TaskURL

func (b *Build) TaskURL() string

TaskURL returns the URL to the buildbucket build for this task.
