Why Engineering Teams Love DeploySentinel

Joe Gaudet

Director of Software Development

Debugging flaky tests using DeploySentinel has been a game changer for our team, allowing us to ship features quickly and confidently. The difference between simple videos is night & day.

Christopher Jamison

Lead QA Software Automation Engineer

Before working with you guys, I would run Cypress tests locally until I got tests to fail because the Cypress Dashboard didn't give enough information. With DeploySentinel, I no longer have to do that.

Get started in less than 2 minutes

Add our plugin with just 2 lines of code. Fully compatible with your existing Cypress test suite, no test changes necessary.

Cypress Framework

Playwright Test Framework

1. Install via NPM or Yarn

2. Import Support & Plugin File to Cypress

Cypress 10 and Above

Cypress 9 and Below

cypress.config.js
// Cypress Config File (cypress.config.js)
const { defineConfig } = require("cypress");
module.exports = defineConfig({
  e2e: {
    setupNodeEvents(on, config) {
      // ❗ Must be declared at the top of the function to prevent conflicts
      [on, config] = require("@deploysentinel/cypress-debugger/plugin")(on, config);
    },
  },
});

cypress/support/e2e.js
1	1		`// Cypress Support File (cypress/support/e2e.js)`
	2	+	`import '@deploysentinel/cypress-debugger/support'; // ❗ Must be imported top of file`
2	3		`import './commands';`

3. Run Cypress with an API Key

Cypress Browser Type

Chrome / Chromium

Electron (Default)

Firefox / Edge (Coming Soon)

4. Parallelize Tests in CI (Optional)

For more parallelization configuration details, check out the parallelization docs.
