Powerful Features for Modern Testing

LPS Tool provides everything you need to build comprehensive load testing scenarios

🔄

Structured Testing

Built on Rounds and Iterations for organized, realistic testing scenarios that simulate real user behavior.

🎛️

Realistic Traffic (Iteration Modes)

Switch Iteration Modes to mimic real users and bursts.

🌐

Distributed Testing

Scale across multiple nodes with master-slave architecture for high-volume load testing.

📊

Real-time Dashboard

Monitor essential metrics with an intuitive dashboard that updates dynamically during tests.

⚡

Declarative Methods

Dynamic value generation with built-in methods for random data, counters, timestamps, and more.

⏭️

SkipIf (Conditional Run)

Skip an iteration based on runtime expressions and variables — ideal for branching logic during a run.

✅

Failure Criteria

Post‑run quality gates (max error rate, P90/P50, etc.) to classify iterations as pass/fail for reporting.

🛑

Termination Rules

Real‑time stop conditions with grace periods (e.g., sustained high error rate) evaluated at the master node.

🛡️

Watchdog Protection

Automatic resource monitoring and test control to prevent the running machine from overload during testing.

Quick Installation

Prerequisite: .NET 8 SDK must be installed on your machine.

# 1) Verify .NET 8 is installed
dotnet --list-sdks
# 2) Install the LPS .NET global tool
dotnet tool install --global lps
# 3) Check the tool is available
lps --help

Tip: If the command isn't found, add the .NET tools path to your PATH environment variable (shown by dotnet tool list -g).

How LPS Tool Works

The LPS structure gives you full control with a simple, powerful architecture

1

Clients

Virtual users that run groups of iterations, simulating gradual user entry into the system.

2

Rounds

Testing phases that run sequentially, each with its own configuration and client count.

3

Iterations

Individual scenarios within a round that define target endpoints and execution behavior.

4

Iteration Modes

Control the pattern and timing of requests to simulate realistic user behavior.
