Overview

Package testbed allows to easily set up a test that requires running the agent and a load generator, measure and define resource consumption expectations for the agent, fail tests automatically when expectations are exceeded.

Each test case requires a agent configuration file and (optionally) load generator spec file. Test cases are defined as regular Go tests.

Agent and load generator must be pre-built and their paths must be specified in test bed config file. The config file location must be provided in TESTBED_CONFIG env variable.

	// ErrorSignal indicates an error in the test case execution, e.g. process execution
	// failure or exceeding resource consumption, etc. The actual error message is already
	// logged, this is only an indicator on which you can wait to be informed.
	ErrorSignal chan struct{}

	// Duration is the requested duration of the tests. Configured via TESTBED_DURATION
	// env variable and defaults to 15 seconds if env variable is unspecified.
	Duration time.Duration
	// contains filtered or unexported fields
}

TestCase defines a running test case.

func NewTestCase 

func NewTestCase(
	t *testing.T,

	sender DataSender,
	receiver DataReceiver,
	agentProc OtelcolRunner,
	validator TestCaseValidator,
	resultsSummary TestResultsSummary,
	opts ...TestCaseOption,
) *TestCase

NewTestCase creates a new TestCase. It expects agent-config.yaml in the specified directory.

func (*TestCase) AgentMemoryInfo 

func (tc *TestCase) AgentMemoryInfo() (uint32, uint32, error)

func (*TestCase) EnableRecording 

func (tc *TestCase) EnableRecording()

EnableRecording enables recording of all data received by MockBackend.

func (*TestCase) SetResourceLimits 

func (tc *TestCase) SetResourceLimits(resourceSpec ResourceSpec)

SetResourceLimits sets expected limits for resource consmption. Error is signaled if consumption during ResourceCheckPeriod exceeds the limits. Limits are modified only for non-zero fields of resourceSpec, all zero-value fields fo resourceSpec are ignored and their previous values remain in effect.

func (*TestCase) Sleep 

func (tc *TestCase) Sleep(d time.Duration)

Sleep for specified duration or until error is signaled.

func (*TestCase) StartAgent 

func (tc *TestCase) StartAgent(args ...string)

StartAgent starts the agent and redirects its standard output and standard error to "agent.log" file located in the test directory.

func (*TestCase) StartBackend 

func (tc *TestCase) StartBackend()

StartBackend starts the specified backend type.

func (*TestCase) StartLoad 

func (tc *TestCase) StartLoad(options LoadOptions)

StartLoad starts the load generator and redirects its standard output and standard error to "load-generator.log" file located in the test directory.

func (*TestCase) Stop 

func (tc *TestCase) Stop()

Stop stops the load generator, the agent and the backend.

func (*TestCase) StopAgent 

func (tc *TestCase) StopAgent()

StopAgent stops agent process.

func (*TestCase) StopBackend 

func (tc *TestCase) StopBackend()

StopBackend stops the backend.

func (*TestCase) StopLoad 

func (tc *TestCase) StopLoad()

StopLoad stops load generator.

func (*TestCase) ValidateData 

func (tc *TestCase) ValidateData()

ValidateData validates data received by mock backend against what was generated and sent to the collector instance(s) under test by the LoadGenerator.

func (*TestCase) WaitFor 

func (tc *TestCase) WaitFor(cond func() bool, errMsg ...interface{}) bool

WaitFor is like WaitForN but with a fixed duration of 10 seconds

func (*TestCase) WaitForN 

func (tc *TestCase) WaitForN(cond func() bool, duration time.Duration, errMsg ...interface{}) bool

WaitForN the specific condition for up to a specified duration. Records a test error if time is out and condition does not become true. If error is signaled while waiting the function will return false, but will not record additional test error (we assume that signaled error is already recorded in indicateError()).

type TestCaseOption 

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

TestCaseOption defines a TestCase option.

func WithConfigFile 

func WithConfigFile(file string) TestCaseOption

WithConfigFile allows a custom configuration file for TestCase.

func WithSkipResults 

func WithSkipResults() TestCaseOption

WithSkipResults option disables writing out results file for a TestCase.

func (TestCaseOption) Apply 

func (o TestCaseOption) Apply(t *TestCase)

Apply takes a TestCase and runs the option function on it.

type TestCaseValidator added in v0.5.0 

type TestCaseValidator interface {
	// Validate executes validation routines and test assertions.
	Validate(tc *TestCase)
	// RecordResults updates the TestResultsSummary for the test suite with results of a single test.
	RecordResults(tc *TestCase)
}

TestCaseValidator defines the interface for validating and reporting test results.

type TestResultsSummary added in v0.5.0 

type TestResultsSummary interface {
	// Create and open the file and write headers.
	Init(resultsDir string)
	// Add results for one test.
	Add(testName string, result interface{})
	// Save the total results and close the file.
	Save()
}

TestResultsSummary defines the interface to record results of one category of testing.

type TraceDataSender 

type TraceDataSender interface {
	DataSender
	SendSpans(traces pdata.Traces) error
}

TraceDataSender defines the interface that allows sending trace data. It adds ability to send a batch of Spans to the DataSender interface.

type TraceDataSenderOld 

type TraceDataSenderOld interface {
	DataSender
	SendSpans(traces consumerdata.TraceData) error
}

TraceDataSender defines the interface that allows sending trace data. It adds ability to send a batch of Spans to the DataSender interface.

type ZipkinDataReceiver 

type ZipkinDataReceiver struct {
	DataReceiverBase
	// contains filtered or unexported fields
}

ZipkinDataReceiver implements Zipkin format receiver.
