}Report holds the data for the full test
Run executes the test
report, err := runner.Run(
"helloworld.Greeter.SayHello",
"localhost:50051",
WithProtoFile("greeter.proto", []string{}),
WithDataFromFile("data.json"),
WithInsecure(true),
)
ExampleRun demonstrates how to use runner package to perform a gRPC load test programmatically. We use the printer package to print the report in pretty JSON format.
Code:
report, err := runner.Run(
"helloworld.Greeter.SayHello",
"localhost:50051",
runner.WithProtoFile("greeter.proto", []string{}),
runner.WithDataFromFile("data.json"),
runner.WithInsecure(true),
)
if err != nil {
fmt.Println(err.Error())
os.Exit(1)
}
printer := printer.ReportPrinter{
Out: os.Stdout,
Report: report,
}
printer.Print("pretty")
MarshalJSON is custom marshal for report to properly format the date
type Reporter struct {
// contains filtered or unexported fields
}Reporter gathers all the results
Finalize all the gathered data into a final report
Run runs the reporter
type Requester struct {
// contains filtered or unexported fields
}Requester is used for doing the requests
Finish finishes the test run
Run makes all the requests and returns a report of results It blocks until all work is done.
func (b *Requester) Stop(reason StopReason)
Stop stops the test
type ResultDetail struct {
Timestamp time.Time `json:"timestamp"`
Latency time.Duration `json:"latency"`
Error string `json:"error"`
Status string `json:"status"`
}ResultDetail data for each result
type RunConfig struct {
// contains filtered or unexported fields
}RunConfig represents the request Configs
StopReason is a reason why the run ended
func ReasonFromString(str string) StopReason
ReasonFromString creates a Status from a string
func (s StopReason) MarshalJSON() ([]byte, error)
MarshalJSON formats a Threshold value into a JSON string
func (s StopReason) String() string
String() is the string representation of threshold
func (s *StopReason) UnmarshalJSON(b []byte) error
UnmarshalJSON prases a Threshold value from JSON string
type Worker struct {
// contains filtered or unexported fields
}Worker is used for doing a single stream of requests in parallel
