aws-lambda-go-test

aws-lambda-go-test

A package that allows to run integration test against lambda function locally

Installing

go mod edit -require github.com/yogeshlonkar/aws-lambda-go-test@latest

or

go get -u github.com/yogeshlonkar/aws-lambda-go-test

Example usage

import (
 alt "github.com/yogeshlonkar/aws-lambda-go-test/local"
)

response, err := alt.Run(alt.Input{
    Payload: "payload",
})
if respose != expected {
  // do fail
}

Input parameters

Run function will set default values and check if the lambda is running or not if not running it will start the lambda and perform RPC API call

Util

util.Response can be used to incrementally test the response returned by lambda. This way the unmarshall is delayed and expected null field un-marshalling can be avoided

import (
  altu "github.com/yogeshlonkar/aws-lambda-go-test/util"
)

response := altu.ParseResponse(responseTxt)

if response.StatusCode != 200 {
  t.Errorf("response.StatusCode=%d, want 200", response.StatusCode)
}

actualHeaders := TestHeaderStruct{} // expected header struct
response.PaseHeaders(&actualHeaders)
if actualHeaders.ContentType == "application/json" {
	t.Errorf("actualHeaders.ContentType=%s, wanted application/json", actualHeaders.ContentType)
}

actualBody := TestBody{} // expected body struct
response.PaseBody(&actualBody)
if len(actualBody.SomeArr) != 1 {
	t.Errorf("len(actualBody.SomeArr)=%d, wanted 1", len(actualBody.SomeArr))
}
