Testing

Test framework for system tests. Starts and interacts with a (multi node) blockchain in Go. Supports

  • CLI
  • Servers
  • Events
  • RPC

Uses:

  • testify
  • gjson
  • sjson Server and client side are executed on the host machine

Developer

Test strategy

System tests cover the full stack via cli and a running (multi node) network. They are more expensive (in terms of time/ cpu) to run compared to unit or integration tests. Therefore, we focus on the critical path and do not cover every condition.

Execute a single test
go test -tags system_test -count=1 -v ./testing --run TestSmokeTest  -verbose
  • Force a binary rebuild before running the test
go test -tags system_test -count=1 -v ./testing --run TestSmokeTest  -verbose -rebuild

Test cli parameters

  • -verbose verbose output
  • -rebuild - rebuild artifacts
  • -wait-time duration - time to wait for chain events (default 30s)
  • -nodes-count int - number of nodes in the cluster (default 4)

Port ranges

With n nodes:

  • 26657 - 26657+n - RPC
  • 1317 - 1317+n - API
  • 9090 - 9090+n - GRPC
  • 16656 - 16656+n - P2P

For example Node 3 listens on 26660 for RPC calls

Functions

func RequireTxFailure

func RequireTxFailure(t *testing.T, got string, containsMsgs ...string)

Types

type CleanupFn

type CleanupFn func()

type EventConsumer

type EventConsumer func(e ctypes.ResultEvent) (more bool)

func CaptureAllEventsConsumer

func CaptureAllEventsConsumer(t *testing.T, optMaxWaitTime ...time.Duration) (c EventConsumer, done func() []ctypes.ResultEvent)

CaptureAllEventsConsumer is an `EventConsumer` that captures all events until `done()` is called to stop or timeout happens. The consumer works async in the background and returns all the captured events when `done()` is called. This can be used to verify that certain events have happened. Example usage:

	c, done := CaptureAllEventsConsumer(t)
	query := `tm.event='Tx'`
	cleanupFn := l.Subscribe(query, c)
	t.Cleanup(cleanupFn)

 // do something in your test that create events

	assert.Len(t, done(), 1) // then verify your assumption

func CaptureSingleEventConsumer

func CaptureSingleEventConsumer() (EventConsumer, *ctypes.ResultEvent)

CaptureSingleEventConsumer consumes one event. No timeout
