PROBE





Probe is a powerful YAML-based workflow automation tool designed for testing, monitoring, and automation tasks.

GitHub Workflow Status GitHub Release Go Documentation

It is a single Go binary with no runtime to install, so the same file runs on your machine, in CI, and from a cron entry. The exit status reflects the result, and a file written as a test becomes a monitor by adding repeat. Probe uses plugin-based actions to execute workflows, making it highly flexible and extensible. Documentation: probe.linyo.ws

Architecture

Features

Similar software is usually one of two things: a test runner, or a prober that monitors. Most of them speak one protocol. Probe is both, across the protocols a web system is actually made of.

  • One file reaches the whole system. HTTP, gRPC, MySQL, PostgreSQL, SQLite, SMTP, IMAP, SSH, shell and a real browser are built in. A single run can call an endpoint, query the row it wrote, and read the mail it sent, with no glue between three tools.
  • Shared steps live in their own file. A scenario usually starts by logging in, and every scenario after the first repeats it. Put those steps in a job file with its endpoint in defaults, and any workflow runs it with uses: embedded, passing the credentials as vars and reading the token back from outputs. The job's steps appear nested under the step that called it.
  • The same file is a test and a monitor. Add repeat to a job and it runs on an interval, reporting 3/3 success (100.0%). There is no second, rewritten copy of the workflow for monitoring.
  • Jobs are a graph, not a list. needs declares only the order that matters, and everything else runs in parallel. probe dag prints that graph as ASCII or Mermaid. Scenario runners walk a file from top to bottom.
  • It behaves the same everywhere. One Go binary, nothing to install alongside it and no service to keep running, so your terminal, a CI step and a cron entry all do the same thing.
  • Actions are plugins. Each one is a separate process behind go-plugin, so a protocol Probe does not cover yet can be added without forking the binary.

Beyond that, a workflow has outputs to pass data between steps and jobs, test to assert on any response, retry, skipif, iteration, wait and timeout, defaults for settings shared across steps, and merging of several YAML files on one command line.

Understanding Probe covers how these fit together, and Comparison says where k6, Hurl, Venom, runn, Blackbox exporter or GitHub Actions is the better answer.

Quick Start

Install the binary:

go install github.com/linyows/probe/cmd/probe@latest

Write a workflow:

# health-check.yml
name: API Health Check
jobs:
- name: Check API Status
  steps:
  - name: Ping API
    uses: http
    with:
      url: https://api.example.com
      get: /health
    test: res.code == 200

Run it:

probe health-check.yml

API Health Check

⏺ Check API Status (Completed in 0.02s)
  ⎿ 0. ✓  Ping API

Total workflow time: 0.02s ✓ All jobs succeeded

Quickstart goes through this step by step, and Your First Workflow grows it into something you can leave running.

Built-in Actions

Action Use it for
http HTTP requests and their responses

Constants

const (
	// ExitOK means every job succeeded.
	ExitOK = 0
	// ExitTestFailed means a test did not hold: it evaluated to false, could
	// not be evaluated, or did not evaluate to a boolean.
	ExitTestFailed = 1
	// ExitConfigError means the workflow or the command line was wrong, or a
	// report file could not be written, so the run could not do what it was
	// asked to.
	ExitConfigError = 2
	// ExitActionError means an action returned an error, such as a refused
	// connection or a timeout, so a test could not be checked at all.
	ExitActionError = 3
)

Exit codes of a probe run. They tell apart what a caller such as CI or cron has to do about a failure: a failed test points at the system under test, a configuration error at the workflow or the command line, and an action error at the environment, such as a target that cannot be reached.

Functions

func BuildReport added in v1.12.0 

func BuildReport(name, description string, rs *Result, order []string, startedAt, finishedAt time.Time) *report.Report

BuildReport assembles a Report from the results of a run. Jobs are listed in the given order, which is the order they are declared in the workflow.

func Guide added in v1.12.0 

func Guide(topic string) (string, error)

type RunOptions struct {
	// Verbose raises the action's log level to debug.
	Verbose bool
	// Quiet silences the action's own log records. It is set for a retry
	// attempt that still has another attempt left: actions have no notion of
	// being retried, so a failure there would otherwise be reported at error
	// level even though the step goes on to succeed.
	Quiet bool
	// Masker hides the workflow's secrets in the action's log records.
	Masker *mask.Masker
}

RunOptions controls how a single action invocation is run and logged.

	// nil when the action asked not to be dumped (res.dump: false).
	Request  map[string]any
	Response map[string]any
}

StepFailure describes a failed step without terminal formatting, so that reports can serialize it.

type StepRepeatCounter struct {
	SuccessCount int
	FailureCount int
	Name         string
	LastResult   bool

StepRepeatCounter tracks the execution results of repeated steps

type StepResult added in v0.6.0 

type StepResult struct {

	EchoOutput    string
	Report        string
	HasTest       bool
	RetryAttempt  int                // Number of attempts made (0 = retry not performed, 1 = succeeded first try)
	RetryMax      int                // Maximum retry attempts configured
	RepeatCounter *StepRepeatCounter // For repeat execution information
	// The fields below feed the report files. Unlike StartedAt and RT they are
	// recorded whether or not --timing is set, and they carry no terminal styling.
	Test    string        // The test expression, empty when the step has none
	Elapsed time.Duration // Wall time from the action's start to the result
	Failure *StepFailure  // Why the step failed; nil unless Status is StatusError
}

StepResult represents the result of a step execution

type StepRetry added in v0.19.0 

type StepRetry struct {
	MaxAttempts  int      `yaml:"max_attempts" validate:"required,gte=1"`
	Interval     Interval `yaml:"interval"`
	InitialDelay Interval `yaml:"initial_delay,omitempty"`
}

StepRetry defines the retry configuration for steps until success (status 0)

func (*StepRetry) Validate added in v0.25.0 

func (s *StepRetry) Validate() error

Validate performs custom validation for StepRetry

type StreamReporter added in v1.11.0 

type StreamReporter struct {
	// contains filtered or unexported fields
}

StreamReporter prints the report incrementally.

A job block is only printed once the job is final, which keeps blocks from interleaving even though jobs run concurrently. Blocks are held back until every earlier job in workflow order has been printed, so the finished report is identical to the buffered one. Step level progress goes to stderr, which is what keeps a CI log alive while the first job is still running.

func NewStreamReporter added in v1.11.0 

func NewStreamReporter(p *Printer) *StreamReporter

NewStreamReporter creates a reporter that flushes job blocks as they finish.

func (*StreamReporter) Finish added in v1.11.0 

func (r *StreamReporter) Finish(rs *Result)

func (*StreamReporter) JobDone added in v1.11.0 

func (r *StreamReporter) JobDone(jobID string, jr *JobResult)

func (*StreamReporter) StepDone added in v1.11.0 

func (r *StreamReporter) StepDone(jobID string, sr StepResult)

func (*StreamReporter) StepStart added in v1.11.0 

func (r *StreamReporter) StepStart(jobID, stepName string)

type Workflow 

type Workflow struct {
	Name        string         `yaml:"name" validate:"required"`
	Description string         `yaml:"description,omitempty"`
	Jobs        []Job          `yaml:"jobs" validate:"required"`
	Vars        map[string]any `yaml:"vars"`
	// Secrets names environment variables whose values must not appear in
	// anything Probe prints or writes.
	Secrets []string `yaml:"secrets,omitempty"`
	// contains filtered or unexported fields
}

func (*Workflow) Env added in v0.3.0 

func (w *Workflow) Env() map[string]string

func (*Workflow) Graph added in v1.16.0 

func (w *Workflow) Graph() dag.Graph

Graph returns the jobs and steps of the workflow in the form the DAG renderers draw. The steps of an embedded job are read from its file, at the path its `with.path` names after the workflow's vars are expanded.

func (*Workflow) SetExitStatus added in v0.2.0 

func (w *Workflow) SetExitStatus(isErr bool)

func (*Workflow) Start 

func (w *Workflow) Start(c Config) error

Start executes the workflow with the given configuration
