Bombardier

Rust based HTTP load testing tool using postman collection
Bombardier can take your existing postman collection and bombard your server with those requests under specified load

Building from source

Make sure you have cargo and rust installed. Checkout the code and run below command
cargo build --release

Config json

You need to create a json file which can tell Bombardier about the load configuration.
If you do not wish to push stats to influxdb for real time monitoring you can skip that configuration. Stats would still be written to report file

{
    "environment_file": "./examples/environment.json",
    "collection_file": "./examples/collection.json",
    "data_file": "./examples/data.csv",
    "thread_count": 1,
    "iterations": 1,
    "thread_delay": 1,
    "execution_time": 1,
    "rampup_time": 1,
    "report_file": "report.csv",
    "continue_on_error": false,
    "handle_cookies": false,
    "influxdb" : {
        "url": "http://localhost:8086",
        "username": "",
        "password": "",
        "dbname": "mydb"
    }
}

For more details regarding configuration json, please check configurations doc.

Benchmarks

I would like this tool to be benchmarked with other tools to see if it needs more improvement. You can find the benchmarks here

Limitations

Bombardier currently will only parse the requests which are directly under collection folder or it's sub-folder. It will ignore requests from folders which are 2 or more levels down in hierarchy. In below example bombardier will ignore all requests under folder 2

├── collection
    ├── request1
    └── folder1
        ├── request2
        ├── request3
        └── folder2
            ├── request4
            └── request5

Bombardier currently cannot generate different loads for different folders under collection. Whole collection will be executed with same thread count
Bombardier cannot parse or execute Postman's javascript written under test tag. Due to this limitation you should explicitly tell bombardier if you wish to extract any value from response to be used in following requests. Refer postprocessor guide for the same
