# Lambda Loadtester

This package runs load tests against Lambda functions.

## Installation

Install using `npm`:

``` bash

npm install lambda-loadtester

```

Create a file `aws-config.json` in the project root directory,

which should contain your AWS credentials and target region:

``` json

{

    "accessKeyId": "AKIA...",

    "secretAccessKey": "...",

    "region": "eu-west-3"

}

```

## Run Test

To run your first test:

``` bash

node bin/run.js --endpoint [name] --body "{}"

```

The following options are available:

### `--endpoint [name]`

The function to invoke, mandatory.

### `--number [n]`

Number of total invocations to run, default 1.

### `--concurrency [c]`

Number of parallel invocations on the fly, default 1.

### `--body [body]`

The payload to send to the lambda function.

No default.

### `--file [path]`

Path to a file that contains a JSON document to send as the body.

## Invocation

The Lambda function is invoked as many times as the parameter `--number [n]`.

When `--concurrency c` is specified,

there will be at most `c` invocations in flight at the same time.

## Results

For every variable in the result it is shown:

total number of values, average and standard deviation.
