Types

type Check

type Check struct {
	Name        string `yaml:"name"`
	Description string `yaml:"description"`

	// regex matchers
	Package    string   `yaml:"package"`
	Benchmarks []string `yaml:"benchmarks"`

	// Diff functions are written as `antonmedv/expr` expressions: https://github.com/antonmedv/expr
	//
	// Two parameters are provided:
	//
	// * `base`: bench.Benchmark
	// * `current`: bench.Benchmark
	//
	// Return a flaot64-castable value. This is then checked against your defined Thresholds
	//
	// In general, calibrate your diff to return:
	//
	// * negative value for improvement
	// * positive value for regression
	//
	DiffFunc   string     `yaml:"diff"`
	Thresholds Thresholds `yaml:"thresholds"`
}

Check describes a set of benchmarks to run a diff on and check against thresholds

type CheckResult

type CheckResult struct {
	Status Status

	Diffs      []DiffResult
	Thresholds Thresholds
}

CheckResult reports the output of a Check

type Config

type Config struct {
	Checks []Check `yaml:"checks"`
}

Config declares checks configurations

func LoadConfig

func LoadConfig(path string) (*Config, error)

LoadConfig reads configuration from the given path

type DiffResult

type DiffResult struct {
	Status Status

	Package   string
	Benchmark string

	Value float64
}

DiffResult is the result of a diff

type EnvDiffFunc

type EnvDiffFunc struct {
	Check *Check
	// contains filtered or unexported fields
}

EnvDiffFunc describes variables provided to a DiffFunc

type EvaluateOptions

type EvaluateOptions struct {
	Debug       bool
	MustFindAll bool
}

EvaluateOptions declares options for checks evaluation

type Report

type Report struct {
	Status Status

	Base    string
	Current string

	Checks map[string]*CheckResult
}

Report reports the output of Evaluate

func Evaluate

func Evaluate(checks []Check, base bench.RunHistory, current bench.RunHistory, opts *EvaluateOptions) (*Report, error)

Evaluate checks against benchmark runs

func LoadReport

func LoadReport(path string) (*Report, error)

LoadReport loads checks results from the given path

type Status

type Status string

Status describes result of a check

const (
	// StatusPass is good!
	StatusPass Status = "pass"
	// StatusFail is bad
	StatusFail Status = "fail"
	// StatusNotFound means no measurements were found
	StatusNotFound Status = "not-found"
)

type Thresholds

type Thresholds struct {
	Min *float64 `yaml:"min,omitempty"`
	Max *float64 `yaml:"max,omitempty"`
}

Thresholds declares values from ChangeFunc to fail
