Cypress + CaptchaAI: E2E Testing with CAPTCHA Handling

CAPTCHAs block automated E2E tests. Disabling them in staging introduces environment drift — bugs that only appear in production where CAPTCHAs are active. CaptchaAI lets your Cypress tests interact with real CAPTCHAs, keeping test environments identical to production.


Why Not Just Disable CAPTCHAs in Tests?

Approach Risk
Disable CAPTCHA in staging Misses integration bugs, form flow differences
Use test keys (always-pass) Doesn't test token injection, callback handling
Solve with CaptchaAI Full production-parity testing

Setup

npm install cypress --save-dev

Cypress Config

// cypress.config.js
const { defineConfig } = require("cypress");

module.exports = defineConfig({
  e2e: {
    baseUrl: "https://your-app.com",
    defaultCommandTimeout: 120000,
    responseTimeout: 120000,
    setupNodeEvents(on, config) {
      on("task", {
        solveCaptcha({ siteUrl, sitekey, type }) {
          return solveCaptchaTask(siteUrl, sitekey, type);
        },
      });
      return config;
    },
  },
  env: {
    CAPTCHAAI_KEY: "YOUR_API_KEY",
  },
});

CaptchaAI Task Handler

// cypress/plugins/captcha-solver.js
const https = require("https");

function httpPost(url, data) {
  return new Promise((resolve, reject) => {
    const params = new URLSearchParams(data).toString();
    const options = {
      method: "POST",
      headers: { "Content-Type": "application/x-www-form-urlencoded" },
    };
    const req = https.request(url, options, (res) => {
      let body = "";
      res.on("data", (c) => (body += c));
      res.on("end", () => resolve(JSON.parse(body)));
    });
    req.on("error", reject);
    req.write(params);
    req.end();
  });
}

function httpGet(url) {
  return new Promise((resolve, reject) => {
    https.get(url, (res) => {
      let body = "";
      res.on("data", (c) => (body += c));
      res.on("end", () => resolve(JSON.parse(body)));
    }).on("error", reject);
  });
}

async function solveCaptchaTask(siteUrl, sitekey, type = "recaptcha_v2") {
  const API = "https://ocr.captchaai.com";
  const key = process.env.CAPTCHAAI_KEY || "YOUR_API_KEY";

  const submitData = {
    key,
    pageurl: siteUrl,
    json: "1",
  };

  if (type === "turnstile") {
    submitData.method = "turnstile";
    submitData.sitekey = sitekey;
  } else {
    submitData.method = "userrecaptcha";
    submitData.googlekey = sitekey;
  }

  const submitResp = await httpPost(`${API}/in.php`, submitData);

  if (submitResp.status !== 1) {
    throw new Error(`Submit failed: ${submitResp.request}`);
  }

  const taskId = submitResp.request;

  // Poll for result
  for (let i = 0; i < 60; i++) {
    await new Promise((r) => setTimeout(r, 5000));

    const params = new URLSearchParams({
      key,
      action: "get",
      id: taskId,
      json: "1",
    });

    const result = await httpGet(`${API}/res.php?${params}`);

    if (result.request === "CAPCHA_NOT_READY") continue;
    if (result.status !== 1) throw new Error(`Solve failed: ${result.request}`);

    return result.request; // The CAPTCHA token
  }

  throw new Error("CAPTCHA solve timeout");
}

module.exports = { solveCaptchaTask };

Wire into cypress.config.js

// cypress.config.js
const { solveCaptchaTask } = require("./cypress/plugins/captcha-solver");

module.exports = defineConfig({
  e2e: {
    setupNodeEvents(on, config) {
      on("task", {
        solveCaptcha({ siteUrl, sitekey, type }) {
          return solveCaptchaTask(siteUrl, sitekey, type);
        },
      });
    },
  },
});

Custom Commands

// cypress/support/commands.js

Cypress.Commands.add("solveCaptcha", (options = {}) => {
  cy.get("[data-sitekey]", { timeout: 10000 }).then(($el) => {
    const sitekey = options.sitekey || $el.attr("data-sitekey");
    const siteUrl = options.siteUrl || cy.url();

    cy.url().then((url) => {
      cy.task("solveCaptcha", {
        siteUrl: url,
        sitekey,
        type: options.type || "recaptcha_v2",
      }).then((token) => {
        // Inject token
        cy.window().then((win) => {
          const responseEl = win.document.querySelector(
            "#g-recaptcha-response"
          );
          if (responseEl) {
            responseEl.value = token;
          }

          // Set all hidden response fields
          win.document
            .querySelectorAll('[name="g-recaptcha-response"]')
            .forEach((el) => {
              el.value = token;
            });

          // Trigger callback if exists
          if (win.___grecaptcha_cfg) {
            const clients = win.___grecaptcha_cfg.clients;
            for (const key in clients) {
              const client = clients[key];
              if (client && typeof client.callback === "function") {
                client.callback(token);
              }
            }
          }
        });
      });
    });
  });
});

Cypress.Commands.add("solveTurnstile", (options = {}) => {
  cy.get("[data-sitekey]", { timeout: 10000 }).then(($el) => {
    const sitekey = options.sitekey || $el.attr("data-sitekey");

    cy.url().then((url) => {
      cy.task("solveCaptcha", {
        siteUrl: url,
        sitekey,
        type: "turnstile",
      }).then((token) => {
        cy.window().then((win) => {
          const input = win.document.querySelector(
            'input[name="cf-turnstile-response"]'
          );
          if (input) input.value = token;
        });
      });
    });
  });
});

E2E Test Examples

Login Flow with reCAPTCHA

// cypress/e2e/login.cy.js
describe("Login with reCAPTCHA", () => {
  it("should log in through a CAPTCHA-protected form", () => {
    cy.visit("/login");

    cy.get("#username").type("testuser");
    cy.get("#password").type("securepassword123");

    // Solve the CAPTCHA
    cy.solveCaptcha();

    // Submit
    cy.get('button[type="submit"]').click();

    // Verify login success
    cy.url().should("include", "/dashboard");
    cy.get(".welcome-message").should("contain", "Welcome, testuser");
  });
});

Registration Flow

// cypress/e2e/register.cy.js
describe("Registration with CAPTCHA", () => {
  it("completes registration with all fields + CAPTCHA", () => {
    cy.visit("/register");

    cy.get("#first-name").type("Test");
    cy.get("#last-name").type("User");
    cy.get("#email").type("test@example.com");
    cy.get("#password").type("StrongPass!123");
    cy.get("#confirm-password").type("StrongPass!123");

    cy.solveCaptcha();

    cy.get("#register-btn").click();
    cy.url().should("include", "/verify-email");
  });
});

Turnstile-Protected Checkout

describe("Checkout with Turnstile", () => {
  it("processes payment through Turnstile-protected checkout", () => {
    cy.visit("/cart");

    cy.get(".checkout-btn").click();
    cy.get("#card-number").type("4242424242424242");
    cy.get("#expiry").type("12/26");
    cy.get("#cvc").type("123");

    cy.solveTurnstile();

  });
});

Retry and Error Handling

// cypress/support/commands.js

Cypress.Commands.add("solveCaptchaWithRetry", (options = {}) => {
  const maxRetries = options.retries || 3;

  function attempt(retryCount) {
    return cy.task("solveCaptcha", {
      siteUrl: options.siteUrl,
      sitekey: options.sitekey,
      type: options.type || "recaptcha_v2",
    }).then((token) => {
      if (!token && retryCount < maxRetries) {
        cy.log(`CAPTCHA retry ${retryCount + 1}/${maxRetries}`);
        cy.wait(2000);
        return attempt(retryCount + 1);
      }
      return token;
    });
  }

  return attempt(0);
});

Jest Integration Test

// For teams that also use Jest for API-level CAPTCHA tests
const { solveCaptchaTask } = require("../cypress/plugins/captcha-solver");

test("CaptchaAI solves reCAPTCHA v2", async () => {
  const token = await solveCaptchaTask(
    "https://www.google.com/recaptcha/api2/demo",
    "6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_mJ-",
    "recaptcha_v2"
  );

  expect(token).toBeDefined();
  expect(token.length).toBeGreaterThan(50);
}, 120000);

Troubleshooting

Issue Cause Fix
cy.task timed out CAPTCHA solve took too long Increase taskTimeout in config
Token rejected Expired before injection Reduce delay between solve and submit
data-sitekey not found CAPTCHA loads dynamically Add explicit cy.wait() or intercept
Callback not triggered Custom callback name Inspect ___grecaptcha_cfg in DevTools
CI fails, local passes Missing env variable Add CAPTCHAAI_KEY to CI secrets

FAQ

Will this slow down my test suite?

Each CAPTCHA solve adds 15-30 seconds. Run CAPTCHA tests in a separate suite or parallelize with Cypress Cloud.

Can I use this with Cypress component testing?

No — component tests don't load real pages. Use this only for E2E tests that hit full page URLs with real CAPTCHAs.

Should I test with real CAPTCHAs or mock them?

Test with real CAPTCHAs in staging E2E. Use mocks in unit tests. This ensures full production parity.

Does CaptchaAI work with Cypress Cloud parallelization?

Yes. Each parallel machine calls the same API key. CaptchaAI handles concurrent requests.



Run E2E tests against production-parity CAPTCHA flows — get your CaptchaAI key and integrate with Cypress.
