What all four can do

✓Report a bug: form with screenshot and annotation, voice, quick actions
✓General feedback
✓Retest after a fix, with a verdict per step
✓Earnings in the tester menu, guided tour, German and English

✓Checklist "What to test": testers tick the steps off in the app

AI runs (auto test, AI retest after a fix) work with Flutter and Expo only.

Quick examples

Flutter Initialize and wrap your app

import 'package:flutter/material.dart';
import 'package:testerpaykit/testerpaykit.dart';

final _navigatorKey = GlobalKey<NavigatorState>();

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  final tpk = await TesterPayKit.initialize(
    config: TesterPayKitConfig(
      projectId: '<project-uuid>',
      apiBaseUrl: 'https://api.testerpaykit.com',
      enableTesterMode: true,
    ),
  );
  runApp(MaterialApp(
    navigatorKey: _navigatorKey,
    navigatorObservers: [tpk.navigatorObserver],
    builder: (context, child) => TesterPayKitWrapper(
      sdk: tpk,
      navigatorKey: _navigatorKey,
      child: child ?? const SizedBox.shrink(),
    ),
    home: const HomeScreen(),
  ));
}

Expo Initialize and report on shake

import { TpkExpo, useShake } from '@testerpaykit/expo';
import { useEffect, useState } from 'react';

export function App() {
  const [tpk, setTpk] = useState<TpkExpo | null>(null);

  useEffect(() => {
    TpkExpo.init({
      projectId: '<project-uuid>',
      testerCode: '<tester-invite-code>',
    }).then(setTpk);
  }, []);

  useShake({
    enabled: !!tpk,
    onShake: () => {
      tpk?.submitBug({
        title: 'Shake-reported bug',
        description: 'Reported by shaking the device.',
        currentScreen: 'HomeScreen',
        severity: 'medium',
      });
    },
  });

  return null;
}

Web / React Mount the tester hub

import { useEffect, useState } from 'react';
import { TesterPayKit } from '@testerpaykit/sdk';
import { TesterPayKitApiClient } from '@testerpaykit/api-client';
import { IndexedDBAdapter } from '@testerpaykit/storage-browser';
import { TpkTesterHub } from '@testerpaykit/react';

export function Tpk({ screen }: { screen: string }) {
  const [sdk, setSdk] = useState<TesterPayKit | null>(null);
  useEffect(() => {
    const instance = new TesterPayKit({
      apiKey: '',
      projectId: '<project-uuid>',
      testerId: '<tester-invite-code>',
      deviceId: crypto.randomUUID(),
      storage: new IndexedDBAdapter(),
      apiClient: new TesterPayKitApiClient({ apiKey: '' }),
      deviceMetadata: { os: 'Web', osVersion: navigator.userAgent, deviceModel: 'browser', appVersion: '1.0.0', sdkVersion: '2.0.0', timezoneOffset: -new Date().getTimezoneOffset() },
      appMetadata: { bundleId: 'com.example.web', version: '1.0.0', buildNumber: '1' },
      autoStartSession: true,
    });
    void instance.init().then(() => setSdk(instance));
  }, []);
  return sdk ? <TpkTesterHub sdk={sdk} currentScreen={screen} /> : null;
}

The example also imports @testerpaykit/sdk, @testerpaykit/api-client and @testerpaykit/storage-browser; with pnpm, add them explicitly.

Swift Start a session, wrap your view

import SwiftUI
import TesterPayKit

let sdk = try await TesterPayKit.initialize(
    config: TesterPayKitConfig(
        projectId: "<project-uuid>",
        testerCode: "<tester-invite-code>",
        apiBaseURL: URL(string: "https://api.testerpaykit.com")!
    )
)
try await sdk.startSession()

ContentView()
    .tpkFeedbackOverlay()
