Apache JMeter CLI Editor

Demo

Overview

The Apache JMeter CLI Editor is a powerful command-line tool that lets you work with JMeter test plans without launching the full GUI. Perfect for quick edits, automation pipelines, and headless environments.

3 Seats Included

Your purchase includes 3 device licenses — install on your laptop, CI server, and a colleague’s machine at no extra cost.

Two Modes of Operation

Interactive TUI Mode

jmeter-edit test.jmx    # Open file in interactive terminal editor

A full terminal UI for browsing and editing your test plan visually.

Batch Mode

jmeter-edit set test.jmx "Test Plan/Thread Group" ThreadGroup.num_threads 50 --save

Script your changes for CI/CD pipelines and automation workflows.

CLI Batch Commands

In addition to the interactive TUI, JMeter CLI Editor provides batch commands for scripting and automation:

jmeter-edit list <file>                    # List tree structure
jmeter-edit get <file> <path>              # Get element properties
jmeter-edit set <file> <path> <prop> <val> # Set property value
jmeter-edit add <file> <parent> <type>     # Add new element
jmeter-edit delete <file> <path>           # Delete element
jmeter-edit enable <file> <path>           # Enable element
jmeter-edit disable <file> <path>          # Disable element
jmeter-edit export <file>                  # Export to JSON

Tree Path Format

Elements are identified by /-delimited paths using their testname:

"Test Plan"                              # Root element
"Test Plan/Thread Group"                 # Child element
"Test Plan/Thread Group/HTTP Request[0]" # First when duplicates exist
"Test Plan/Thread Group/HTTP Request[1]" # Second when duplicates exist

CLI Examples

# List tree structure
jmeter-edit list test.jmx
jmeter-edit list test.jmx --depth 2 --show-properties

# Get element properties
jmeter-edit get test.jmx "Test Plan/Thread Group"
jmeter-edit get test.jmx "Test Plan/Thread Group" -p ThreadGroup.num_threads --json

# Set property and save
jmeter-edit set test.jmx "Test Plan/Thread Group" ThreadGroup.num_threads 100 --save
jmeter-edit set test.jmx "Test Plan/Thread Group" --name "API Users" --save

# Add new element
jmeter-edit add test.jmx "Test Plan/Thread Group" HTTPSamplerProxy --name "Login Request" --save
jmeter-edit add test.jmx "Test Plan/Thread Group" ConstantTimer -p ConstantTimer.delay=1000 --save

# Enable/disable elements
jmeter-edit disable test.jmx "Test Plan/Debug PostProcessor" --save
jmeter-edit enable test.jmx "Test Plan/Debug PostProcessor" --save

# Delete element
jmeter-edit delete test.jmx "Test Plan/Thread Group/View Results Tree" --save

# Export to JSON
jmeter-edit export test.jmx --flatten --include-properties -o export.json

CI/CD Integration

Batch update multiple test files in your pipeline:

# Update thread counts across all test files
for f in *.jmx; do
  jmeter-edit set "$f" "Test Plan/Thread Group" ThreadGroup.num_threads 100 --save
done

# Disable debug samplers before production run
for f in *.jmx; do
  jmeter-edit disable "$f" "Test Plan/Debug Sampler" --save 2>/dev/null || true
done

# Export all test plans to JSON for documentation
for f in *.jmx; do
  jmeter-edit export "$f" --flatten -o "${f%.jmx}.json"
done

Key Benefits

Speed & Efficiency

Make rapid adjustments to your JMX files without waiting for the JMeter GUI to load. Ideal for CI/CD pipelines and scripted workflows.

Cross-Platform Support

Available for:

• Linux (x86_64)
• Windows (x86_64)

Lightweight

Minimal resource footprint - runs efficiently on any machine without the overhead of a graphical interface.

Why CLI Editor?

Need	Without CLI Editor	With CLI Editor
Change thread count / ramp-up	Launch full JMeter GUI (slow)	One command, <5 seconds
Batch update 20+ JMX files	Manual or fragile scripts (error-prone)	Scriptable, safe edits in loop
Edit on headless Linux server	Impossible without X forwarding	Native binary, zero GUI deps
CI/CD parameterization	Property files only (limited)	Direct JMX patching + version control

The Investment

£29 one-time for 3 seats — under £10 per user. No recurring fees like enterprise JMeter cloud platforms.

Cheaper than one hour of a senior performance engineer’s time, yet it pays for itself after a handful of batch edits or pipeline tweaks.

Use Cases

• Quick modifications to thread counts, durations, or endpoints
• Batch editing multiple JMX files in CI/CD pipelines
• Remote server management where GUI isn’t available
• Scripted test plan generation and modification
• Exporting test structure for documentation or analysis

• 3 device licenses — laptop, CI server, colleague
• CLI Editor executable for your chosen platform
• Full batch mode command reference
• Free updates within the major version
