Bloader is a cutting-edge load testing tool designed for simplicity and flexibility. While still in active development, it already offers robust features to execute and manage load tests effectively. We welcome contributions from the community to help shape its future. 💡

Warning

This page describes minimal documentation but does not explain the definition of a loader.

See Bloader Docs for more information.

✨ Key Features

✔️ Internal Storage: Bloader can store request data for enhanced testing capabilities.

✔️ Master-Slave Architecture: Avoid client-side bottlenecks by leveraging gRPC communication between Master and Slave nodes.

✔️ Human-Friendly Configuration: Load tests are defined using YAML, with support for Sprig's template engine (used in Helm), offering exceptional flexibility.

🛠️ Installation

Many installation methods are supported, details of which can be found at Installation for details.

📄 Configuration File Support

Bloader supports multiple formats, including YAML, JSON, and TOML, via the Viper library. Configuration items differ for Master and Slave nodes and can be overridden by environment variables prefixed with BLOADER_, which take precedence over file-based configurations.

Example: Master Configuration

version: v1
type: master
env: "production"
loader:
  base_path: "loader"
targets:
  - id: "apiServer"
    type: "http"
    values:
      - env: "local"
        url: "http://localhost:8080"
      - env: "production"
        url: "https://api.example.org"
outputs:
  - id: "localOutput"
    values:
      - env: "production"
        type: "local"
        format: "csv"
        base_path: "outputs/prod"
store:
  file:
    - env: "production"
      path: "local_store/prod_store.db"
encrypts:
  - id: "dynamicEncrypt"
    type: "dynamicCBC"
    store:
      bucket_id: "encryptBucket"
      key: "dynamicKey"
server:
  port: 9800
logging:
  output:
    - type: "stdout"
      format: "text"
      level: "warn"

Example: Slave Configuration

version: v1
type: slave
env: "production"
slave_setting:
  port: 50051
  certificate:
    enabled: true
    slave_cert: "certs/slave.crt"
    slave_key: "certs/slave.key"
logging:
  output:
    - type: "file"
      filename: "logs/slave.log"
      format: "text"
      level: "warn"
