Easy Start

This section aims to show you how to use Ddosify without deep dive into its details easily.

Simple load test
```
 ddosify -t target_site.com
```
The above command runs a load test with the default value that is 100 requests in 10 seconds.
Using some of the features
```
 ddosify -t target_site.com -n 1000 -d 20 -p HTTPS -m PUT -T 7 -P http://proxy_server.com:80
```
Ddosify sends a total of 1000 PUT requests to https://target_site.com over proxy http://proxy_server.com:80 in 20 seconds with a timeout of 7 seconds per request.
Usage for CI/CD pipelines (JSON output)
```
 ddosify -t target_site.com -o stdout-json | jq .avg_duration
```
Ddosify outputs the result in JSON format. Then jq (or any other command-line JSON processor) fetches the avg_duration. The rest depends on your CI/CD flow logic.
Scenario based load test
```
 ddosify -config config_examples/config.json
```
Ddosify first sends HTTP/2 POST request to https://test_site1.com/endpoint_1 using basic auth credentials test_user:12345 over proxy http://proxy_host.com:proxy_port and with a timeout of 3 seconds. Once the response is received, HTTPS GET request will be sent to https://test_site1.com/endpoint_2 along with the payload included in config_examples/payload.txt file with a timeout of 2 seconds. This flow will be repeated 20 times in 5 seconds and response will be written to stdout.
Load test with Dynamic Variables (Parameterization)
```
 ddosify -t target_site.com/{{_randomInt}} -d 10 -n 100 -h 'User-Agent: {{_randomUserAgent}}' -b '{"city": "{{_randomCity}}"}'
```
Ddosify sends a total of 100 GET requests to https://target_site.com/{{_randomInt}} in 10 seconds. {{_randomInt}} path generates random integers between 1 and 1000 in every request. Dynamic variables can be used in URL, headers, payload (body) and basic authentication. In this example, Ddosify generates a random user agent in the header and a random city in the body. The full list of the dynamic variables can be found in the docs.

Details

You can configure your load test by the CLI options or a config file. Config file supports more features than the CLI. For example, you can't create a scenario-based load test with CLI options.

Config File

Config file lets you use all capabilities of Ddosify.

The features you can use by config file;

Scenario creation
Custom load type creation
Payload from a file
Multipart/form-data payload
Extra connection configuration, like keep-alive enable/disable logic
HTTP2 support

Usage;

ddosify -config <json_config_path>

There is an example config file at config_examples/config.json. This file contains all of the parameters you can use. Details of each parameter;

request_count optional

This is the equivalent of the -n flag. The difference is that if you have multiple steps in your scenario, this value represents the iteration count of the steps.
load_type optional

This is the equivalent of the -l flag.
duration optional

This is the equivalent of the -d flag.
manual_load optional

If you are looking for creating your own custom load type, you can use this feature. The example below says that Ddosify will run the scenario 5 times, 10 times, and 20 times, respectively along with the provided durations. request_count and duration will be auto-filled by Ddosify according to manual_load configuration. In this example, request_count will be 35 and the duration will be 18 seconds. Also manual_load overrides load_type if you provide both of them. As a result, you don't need to provide these 3 parameters when using manual_load.
```
"manual_load": [
    {"duration": 5, "count": 5},
    {"duration": 6, "count": 10},
    {"duration": 7, "count": 20}
]
```
proxy optional

This is the equivalent of the -P flag.
output optional

This is the equivalent of the -o flag.

steps mandatory

This parameter lets you create your scenario. Ddosify runs the provided steps, respectively. For the given example file step id: 2 will be executed immediately after the response of step id: 1 is received. The order of the execution is the same as the order of the steps in the config file.

Details of each parameter for a step;

id mandatory

Each step must have a unique integer id.
url mandatory

This is the equivalent of the -t flag.
name optional

Name of the step.
protocol optional

This is the equivalent of the -p flag.
method optional

This is the equivalent of the -m flag.
headers optional

List of headers with key:value format.
payload optional

This is the equivalent of the -b flag.
payload_file optional

If you need a long payload, we suggest using this parameter instead of payload.

payload_multipart optional

Use this for multipart/form-data Content-Type.

Accepts list of form-field objects, structured as below;

{
    "name": [field-name],
    "value": [field-value|file-path|url],
    "type": <text|file>,    // Default "text"
    "src": <local|remote>   // Default "local"
}

Example: Sending form name-value pairs;

"payload_multipart": [
    {
        "name": "[field-name]",
        "value": "[field-value]"
    }
]

Example: Sending form name-value pairs and a local file;

"payload_multipart": [
    {
        "name": "[field-name]",
        "value": "[field-value]",
    },
    {
        "name": "[field-name]",
        "value": "./test.png",
        "type": "file"
    }
]

Example: Sending form name-value pairs and a local file and a remote file;

"payload_multipart": [
    {
        "name": "[field-name]",
        "value": "[field-value]",
    },
    {
        "name": "[field-name]",
        "value": "./test.png",
        "type": "file"
    },
    {
        "name": "[field-name]",
        "value": "http://test.com/test.png",
        "type": "file",
        "src": "remote"
    }
]

Note: Ddosify adds Content-Type: multipart/form-data; boundary=[generated-boundary-value] header to the request when using payload_multipart.

timeout optional

This is the equivalent of the -T flag.

sleep optional

Sleep duration(ms) before executing the next step. Can be an exact duration or a range.

Example: Sleep 1000ms after step-1;

"steps": [
    {
        "id": 1,
        "url": "target.com/endpoint1",
        "sleep": "1000"
    },
    {
        "id": 2,
        "url": "target.com/endpoint2",
    }
]

Example: Sleep between 300ms-500ms after step-1;

"steps": [
    {
        "id": 1,
        "url": "target.com/endpoint1",
        "sleep": "300-500"
    },
    {
        "id": 2,
        "url": "target.com/endpoint2",
    }
]

auth optional

Basic authentication.

"auth": {
    "username": "test_user",
    "password": "12345"
}

others optional

This parameter accepts dynamic key: value pairs to configure connection details of the protocol in use.

"others": {
    "keep-alive": true,              // Default true
    "disable-compression": false,    // Default true
    "h2": true,                      // Enables HTTP/2. Default false.
    "disable-redirect": true         // Default false
}

Parameterization (Dynamic Variables)

Just like the Postman, Ddosify supports parameterization (dynamic variables) on URL, headers, payload (body) and basic authentication. Actually, we support all the random methods Postman supports. If you use {{$randomVariable}} on Postman you can use it as {{_randomVariable}} on Ddosify. Just change $ to _ and you will be fine. To simulate a realistic load test on your system, Ddosify can send every request with dynamic variables.

The full list of dynamic variables can be found in the Ddosify Docs.

Parameterization on URL

Ddosify sends 100 GET requests in 10 seconds with random string key parameter. This approach can be also used in cache bypass.

ddosify -t target_site.com/?key={{_randomString}} -d 10 -n 100

Parameterization on Headers

Ddosify sends 100 GET requests in 10 seconds with random Transaction-Type and Country headers.

ddosify -t target_site.com -d 10 -n 100 -h 'Transaction-Type: {{_randomTransactionType}}' -h 'Country: {{_randomCountry}}'

Parameterization on Payload (Body)

Ddosify sends 100 GET requests in 10 seconds with random latitude and longitude values in body.

ddosify -t target_site.com -d 10 -n 100 -b '{"latitude": "{{_randomLatitude}}", "longitude": "{{_randomLongitude}}"}'

Parameterization on Basic Authentication

Ddosify sends 100 GET requests in 10 seconds with random username and password with basic authentication.

ddosify -t target_site.com -d 10 -n 100 -a '{{_randomUserName}}:{{_randomPassword}}'

Parameterization on Config File

Dynamic variables can be used on config file as well. Ddosify sends 100 GET requests in 10 seconds with random string key parameter in URL and random User-Key header.

ddosify -config ddosify_config_dynamic.json

// ddosify_config_dynamic.json
{
    "request_count": 100,
    "load_type": "linear",
    "duration": 10,
    "steps": [
        {
            "id": 1,
            "url": "https://test_site1.com/?key={{_randomString}}",
            "protocol": "https",
            "method": "POST",
            "headers": {
                "User-Key": "{{_randomInt}}"
            }
        }
    ]
}
