Mock Jutsu - JMeter Plugin

Generate 5955-tested, format-valid mock test data directly inside JMeter test plans — no Python, no subprocess, no external dependencies.

Performance Verification — Benchmark

All 423 types are tested under 1 000-concurrent wave load (per-sampler SyncTimer, all 1 000 threads fire simultaneously). The test plans are publicly available so anyone can reproduce the results independently:

mock-jutsu-jmeter-plugin-benchmark — download, run against your own JMeter installation, verify the numbers yourself.

Baseline (v1.1.1, Java 25, 1 000 concurrent threads, setUp warmup applied):

Type	Tier	Avg (ms)	p95 (ms)
tckn	Fast	0.028	0.043
cardnum:visa	Fast	0.038	0.059
oidc_token_set	Slow	0.898	1.491

347 of 423 types (82%) average under 0.05 ms. Only 5 types exceed 0.15 ms (OIDC, AI, and Prometheus types) — these should be pre-generated via CSV for production load tests.

Full latency tables (avg, p50, p95, p99) and CPU/RAM profiles are available in the QA Analysis Report.

Syntax

Use pipe | to separate options inside the Function Helper — JMeter does not escape |, so the output is always clean with no backslashes.

${__mockjutsu_<category>(type[:qualifier][|locale][|varName][|mask])}

Token	Required	Description
type[:qualifier]	Yes	Data type, optionally with a qualifier after : (e.g. cardnum:visa, balance:100|5000)
locale	No	TR · DE · FR · UK · US · RU — omit for locale-agnostic types
varName	No	Any other word stores the result in a JMeter variable
mask	No	Keyword — returns a regulation-compliant masked value (PCI DSS, GDPR, KVKK…)

Backward compatible: multi-param comma style (type,locale,varName,mask) also works — JMeter treats each comma as a parameter separator, not an escaped value.

Examples

${__mockjutsu_financial(cardnum)}                     → 4532015112830366
${__mockjutsu_financial(cardnum:visa)}                → 4532015112830366  (Visa forced)
${__mockjutsu_financial(cardnum|TR)}                  → 4532015112830366  (Turkish locale)
${__mockjutsu_financial(cardnum:visa|mask)}           → 4532 01** **** 0366  (PCI DSS masked)
${__mockjutsu_financial(cardnum:visa|TR|mask)}        → 4532 01** **** 0366
${__mockjutsu_financial(cardnum:visa|TR|myCard)}      → stores result in ${myCard}
${__mockjutsu_financial(cardnum:visa|TR|myCard|mask)} → masked + stored in ${myCard}
${__mockjutsu_meta(reverse_regex:[A-Z]{3}\d{4})}      → XKM7291

Real-World Examples

HTTP Request body with dynamic TCKN + IBAN

{
  "citizenId": "${__mockjutsu_identity(tckn|TR)}",
  "iban": "${__mockjutsu_financial(iban|TR)}",
  "cardNumber": "${__mockjutsu_financial(cardnum|TR|card)}",
  "requestId": "${__mockjutsu_meta(uuid|rid)}"
}

Regulation-compliant masked output

{
  "maskedCard": "${__mockjutsu_financial(cardnum:visa|TR|mask)}",
  "maskedTckn": "${__mockjutsu_identity(tckn|TR|mask)}",
  "maskedIban": "${__mockjutsu_financial(iban|TR|mask)}"
}

Storing and reusing values

// Generate once, reuse everywhere
${__mockjutsu_identity(tckn|TR|myTckn)}

// Later in the same request or another sampler:
${myTckn}

Reverse Regex — generate any pattern

${__mockjutsu_meta(reverse_regex:[A-Z]{3}\d{4})}     → XKM7291
${__mockjutsu_meta(reverse_regex:\d{2}/\d{2}/\d{4})} → 14/07/2026
${__mockjutsu_meta(reverse_regex:[A-Fa-f0-9]{8})}    → 3f8a1c2d

Multi-locale load test

${__mockjutsu_identity(ssn|US)}     // US Social Security Number
${__mockjutsu_identity(nin|UK)}     // UK National Insurance Number
${__mockjutsu_identity(tckn|TR)}    // Turkish Citizen ID
${__mockjutsu_financial(iban|DE)}   // German IBAN (MOD-97 valid)

International ID load test

${__mockjutsu_intl_ids(br_cpf)}     // Brazil CPF
${__mockjutsu_intl_ids(in_aadhaar)} // India Aadhaar
${__mockjutsu_intl_ids(cn_ric)}     // China Resident ID
${__mockjutsu_intl_ids(kr_rrn)}     // South Korea RRN

Groovy / JSR223 Sampler — Direct Java

All 390 types are also callable directly from a JSR223 Sampler (Groovy) without the ${__mockjutsu_xxx} expression syntax, using MockJutsuRegistry as the single entry point:

import com.mockjutsu.jmeter.MockJutsuRegistry
import com.mockjutsu.jmeter.MaskerUtil

// Basic: type + locale
def citizenId = MockJutsuRegistry.generate("tckn",    "TR")
def iban      = MockJutsuRegistry.generate("iban",    "TR")
def cardNum   = MockJutsuRegistry.generate("cardnum", "TR", "visa")  // with qualifier
def requestId = MockJutsuRegistry.generate("uuid",    "")

// Store in JMeter variables for use in downstream samplers
vars.put("citizenId", citizenId)
vars.put("iban",      iban)
vars.put("cardNumber", cardNum)
vars.put("requestId", requestId)

// Build inline JSON body
def body = """{
  "citizenId":  "${citizenId}",
  "iban":       "${iban}",
  "cardNumber": "${cardNum}",
  "requestId":  "${requestId}"
}"""
vars.put("requestBody", body)

// Masking (PCI / GDPR)
def maskedIban = MaskerUtil.mask("iban", iban)
vars.put("ibanMasked", maskedIban)

Use the Java API when you need runtime flexibility — loops, conditionals, or dynamic type selection — that the expression syntax cannot provide. For all available type names, see the HOW-TO documentation.

Note: Groovy JSR223 requires Java 17 or Java 21 LTS. Java 25 is not yet supported by Groovy 3.x (Unsupported class file major version 69). Use BeanShell as a drop-in alternative on Java 25 — syntax is identical except semicolons are required.

Pre-generating CSV test data

import com.mockjutsu.jmeter.MockJutsuRegistry
import java.io.*

int N = 1000
String D = "C:/load-test-data/"
new File(D).mkdirs()

PrintWriter pw = new PrintWriter(new OutputStreamWriter(
    new FileOutputStream(D + "identity.csv"), "UTF-8"))
pw.println("tckn,iban")
for (int i = 0; i < N; i++) {
    pw.println(MockJutsuRegistry.generate("tckn", "TR") + "," +
               MockJutsuRegistry.generate("iban", "TR"))
}
pw.close()
log.info("[mock-jutsu] identity.csv (" + N + " satır)")

SampleResult.setResponseData("Done → " + D, "UTF-8")
SampleResult.setSuccessful(true)
