Integracija API za obremenilno testiranje

Ta vodnik pojasnjuje, kako uporabiti odjemalca API LoadFocus, tako prek vmesnika ukazne vrstice (CLI) kot z neposredno uporabo knjižnice JavaScript v vaših aplikacijah.

Kazalo vsebine

Namestitev

Globalna namestitev

npm install -g @loadfocus/loadfocus-api-client

Namestitev v lokalni projekt

npm install @loadfocus/loadfocus-api-client

Konfiguracija

Pred uporabo odjemalca API LoadFocus morate konfigurirati svoje poverilnice API.

Konfiguracija CLI

# Set API key and team ID
loadfocus-api config set apikey YOUR_API_KEY
loadfocus-api config set teamid YOUR_TEAM_ID
# Verify configuration
loadfocus-api config show

Konfiguracija JavaScript

const { configManager } = require('@loadfocus/loadfocus-api-client');
// Set configuration
configManager.set('apikey', 'YOUR_API_KEY');
configManager.set('teamid', 'YOUR_TEAM_ID');
// Verify configuration
console.log(configManager.get('apikey')); // Should print your API key
console.log(configManager.isConfigured()); // Should print true if all required config is set

Vmesnik ukazne vrstice (CLI)

Odjemalec API LoadFocus zagotavlja celovit CLI za interakcijo z API LoadFocus.

Izvedba testa JMeter

Izvedba testa

# Execute a test by name
loadfocus-api jmeter execute --name "My JMeter Test"
# Execute a test with specific parameters
loadfocus-api jmeter execute --name "My JMeter Test" --threads 50 --rampup 30 --duration 300

Zagon testa in čakanje na dokončanje

# Run a test and wait for completion
loadfocus-api jmeter run-test --name "My JMeter Test"
# Run a test with thresholds
loadfocus-api jmeter run-test --name "My JMeter Test" --thresholds "avgresponse<=200,errors==0,p95<=250"
# Run a test with custom timeout and polling interval
loadfocus-api jmeter run-test --name "My JMeter Test" --waitTimeout 1800 --pollInterval 15

Spremljanje statusa testa

# Check status of a test by name and ID
loadfocus-api jmeter status --name "My JMeter Test" --id 12345
# Get a list of recent test runs
loadfocus-api jmeter runs --limit 10

Pridobivanje rezultatov

# Get results for a specific test
loadfocus-api jmeter results --name "My JMeter Test" --id 12345
# Get results with specific metrics
loadfocus-api jmeter results --name "My JMeter Test" --id 12345 --include samples,avgresponse,errors

Delo s pragovi

Ukaz run-test podpira vrednotenje pragov za samodejno določanje, ali test uspe ali ne uspe na podlagi metrik zmogljivosti.

# Run a test with multiple thresholds
loadfocus-api jmeter run-test --name "My JMeter Test" --thresholds "avgresponse<=200,errors==0,p95<=250,hitspersec>=10"

Podprti operatorji pragov:

  • <= - Manjše ali enako
  • < - Manjše od
  • >= - Večje ali enako
  • > - Večje od
  • == - Enako
  • != - Ni enako

Oblike izhodnih podatkov

# Get results in JSON format
loadfocus-api jmeter run-test --name "My JMeter Test" --format json > results.json
# Default pretty-printed output
loadfocus-api jmeter run-test --name "My JMeter Test"

Uporaba knjižnice JavaScript

Odjemalec API LoadFocus se lahko uporablja tudi neposredno kot knjižnica JavaScript v vaših aplikacijah.

Osnovna nastavitev

// Import the LoadFocus API Client
const loadfocus = require('@loadfocus/loadfocus-api-client');
// Access specific components
const { JMeterClient, configManager } = loadfocus;

Odjemalec JMeter

// Create a JMeter client
const jmeterClient = new loadfocus.JMeterClient();
// Or with explicit configuration
const jmeterClient = new loadfocus.JMeterClient({
apikey: 'YOUR_API_KEY',
teamid: 'YOUR_TEAM_ID'
});

Izvedba testov

async function executeTest() {
try {
const result = await jmeterClient.execute({
testrunname: 'My JMeter Test',
threads: 50,
rampup: 30,
duration: 300
});
console.log('Test execution started:', result);
return result.testrunid; // Return the test ID for later use
} catch (error) {
console.error('Error executing test:', error);
}
}

Spremljanje statusa testa

async function checkTestStatus(testName, testId) {
try {
const status = await jmeterClient.getStatus({
testrunname: testName,
testrunid: testId
});
console.log('Test status:', status);
return status.state; // Return the current state
} catch (error) {
console.error('Error checking test status:', error);
}
}

Pridobivanje rezultatov

async function getTestResults(testName, testId) {
try {
// Get available labels for the test
const labels = await jmeterClient.getLabels({
testrunname: testName,
testrunid: testId
});
console.log('Test labels:', labels);
// Get results for each label
const allResults = [];
for (const label of labels) {
const labelResults = await jmeterClient.getResults({
testrunname: testName,
testrunid: testId,
filter: label
});
allResults.push({
label,
results: labelResults
});
}
console.log('Test results:', allResults);
return allResults;
} catch (error) {
console.error('Error retrieving test results:', error);
}
}

Celoten primer

Tukaj je celoten primer, ki izvede test, počaka na dokončanje in pridobi rezultate:

const { JMeterClient, configManager } = require('@loadfocus/loadfocus-api-client');
// Set up configuration
configManager.set('apikey', 'YOUR_API_KEY');
configManager.set('teamid', 'YOUR_TEAM_ID');
// Create client
const jmeterClient = new JMeterClient();
async function runCompleteTest() {
try {
// Execute the test
console.log('Executing test...');
const executeResult = await jmeterClient.execute({
testrunname: 'My JMeter Test'
});
const testId = executeResult.testrunid;
console.log(`Test execution started with ID: ${testId}`);
// Wait for completion
console.log('Waiting for test to complete...');
let completed = false;
while (!completed) {
const status = await jmeterClient.getStatus({
testrunname: 'My JMeter Test',
testrunid: testId
});
console.log(`Current state: ${status.state}`);
if (status.state === 'finished') {
completed = true;
} else if (status.state === 'failed' || status.state === 'error') {
throw new Error(`Test failed with state: ${status.state}`);
} else {
// Wait before checking again
await new Promise(resolve => setTimeout(resolve, 10000));
}
}
// Get results
console.log('Getting test results...');
const labels = await jmeterClient.getLabels({
testrunname: 'My JMeter Test',
testrunid: testId
});
const allResults = [];
for (const label of labels) {
const labelResults = await jmeterClient.getResults({
testrunname: 'My JMeter Test',
testrunid: testId,
filter: label
});
allResults.push({
label,
results: labelResults
});
}
console.log('Test results:', JSON.stringify(allResults, null, 2));
return allResults;
} catch (error) {
console.error('Error running test:', error);
}
}
// Run the test
runCompleteTest();

Napredna uporaba

Prilagojena konfiguracija HTTP

Prilagodite lahko odjemalca HTTP, ki ga uporablja odjemalec API LoadFocus:

const { JMeterClient } = require('@loadfocus/loadfocus-api-client');
// Create client with custom HTTP options
const jmeterClient = new JMeterClient({
apikey: 'YOUR_API_KEY',
teamid: 'YOUR_TEAM_ID',
httpOptions: {
timeout: 30000, // 30 seconds
retries: 3,
headers: {
'User-Agent': 'My Custom Application'
}
}
});

Obravnavanje napak

Odjemalec API LoadFocus zagotavlja podrobne informacije o napakah:

try {
const result = await jmeterClient.execute({
testrunname: 'My JMeter Test'
});
} catch (error) {
if (error.response) {
// The request was made and the server responded with a status code
// that falls out of the range of 2xx
console.error('API Error:', error.response.status, error.response.data);
} else if (error.request) {
// The request was made but no response was received
console.error('Network Error:', error.request);
} else {
// Something happened in setting up the request that triggered an Error
console.error('Request Error:', error.message);
}
}

Odpravljanje težav

Pogoste težave

  1. Napake pri avtentikaciji:

    • Prepričajte se, da sta vaš API ključ in ID ekipe pravilno konfigurirana
    • Preverite, da ima vaš API ključ potrebna dovoljenja
  2. Neuspeh pri izvedbi testa:

    • Preverite, da ime testa obstaja v vašem računu LoadFocus
    • Preverite, ali ste dosegli omejitev sočasnih testov vašega računa
  3. Težave s časovno omejitvijo:

    • Za dolgotrajne teste povečajte parameter waitTimeout
    • Razmislite o implementaciji mehanizma za periodično preverjanje namesto sinhronega čakanja
  4. Težave pri pridobivanju rezultatov:

    • Prepričajte se, da je test končan, preden pridobivate rezultate
    • Preverite, ali je ID testa pravilen

Odpravljanje napak

Omogočite podrobno beleženje za več informacij:

// In your JavaScript code
process.env.DEBUG = 'true';
// Or when using the CLI
DEBUG=true loadfocus-api jmeter run-test --name "My JMeter Test"
