Checksum

Overview of Checksum - AI Powered End-to-End Test Generation

Checksum is an AI-powered testing tool that automatically generates and maintains end-to-end tests for web applications based on real user sessions. This allows developers to ship code faster without worrying about breaking existing functionality.

How Does It Work?

Checksum works by training machine learning models on your actual user sessions in production. The models learn how real users interact with your app and the various flows they take. This allows Checksum to generate comprehensive tests that cover typical usage as well as edge cases.

The generated tests use open source testing frameworks like Cypress and Playwright so you have full control. The tests automatically adapt as your code changes so they stay maintained over time without any extra work.

Key Features and Benefits

Auto-Generated Tests

• Save months of development time with AI generated tests based on real user sessions
• Focus engineering efforts on building features instead of writing tests

Comprehensive Coverage

• ML models trained on your users provide full test coverage of typical and edge cases
• No more worrying about missing critical paths in your app

No Maintenance Required

• Tests automatically adapt to code changes and flakiness
• Get tests that always stay up to date without any extra work

Bug Detection

• Find issues early while coding and save hours of firefighting bugs in production
• Shift left on catching bugs makes developers more productive

Open Source Frameworks

• Generated tests use Cypress and Playwright code so you stay in control
• Integrate into your existing frameworks and workflows

Quick Integration

• Privacy focused data collection and automatic SDK setup
• Start generating tests in minutes with minimal integration work

Use Cases and Applications

Checksum is useful for any web application that wants to ship features faster without sacrificing quality. Some examples include:

• Ecommerce sites - test checkout flows, promotions, user accounts
• SaaS dashboards - test settings, workflows, permissions
• Banking portals - test forms, transactions, edge cases
• Media sites - test video playback, comments, responsiveness

For any app with end users, Checksum can generate relevant test scenarios based on real usage. This provides safety for rapid iterations and frequent deployments.

Who Is It For?

Checksum is designed for engineering and quality assurance teams at technology companies. Specific roles that can benefit include:

• Software engineers - focus on building instead of manual test writing
• QA engineers - get automated tests without any maintenance
• DevOps engineers - gain confidence for frequent deployments
• Product managers - safeguard against regressions when shipping new features
• CTOs/VP Engineering - enable feature velocity without sacrificing quality

Support and Documentation

• Get onboarding, support, and maintenance from Checksum's team
• Documentation covers integration, usage, and troubleshooting
• Email and chat support during business hours
• Slack community for discussions with other users

Integrations

• CI/CD platforms: GitHub Actions, CircleCI, Jenkins, etc.
• Test runners: Jest, Mocha
• Alerting: Slack, PagerDuty
• Dashboards: Datadog, New Relic, Splunk

API and Customization

Checksum provides a REST API that allows generating additional tests, retrieving test results, and configuring the system programmatically.

Teams can customize tests by providing scripts that get compiled into the final tests. This allows modeling very specific scenarios.

Testimonials and Reviews

"Having a testing suite that provides instant feedback and tests every flow of my app makes my team faster. Less firefighting, faster code reviews, and frequent deployments." - CTO, Ketch

Checksum has over a 4.5 star average on G2, with praise for the automated maintenance and comprehensive coverage.

Frequently Asked Questions

How does Checksum generate tests without access to new code?

Our models can extrapolate from existing production sessions to generate relevant test flows even for new features. By learning UI conventions, we can generate robust tests without any user sessions.

What kind of tests are generated?

End-to-end UI tests using the Cypress and Playwright testing frameworks. The tests run like a real user navigating your application.

What data does Checksum collect?

User sessions are recorded like FullStory and Peek, then hashed to protect privacy. Sensitive elements can be masked during collection.

What is the impact on app performance?

Checksum uses battle-tested open source tools with minimal overhead. There is no discernible impact on production app performance.

How long does integration take?

Integration can be completed in minutes by installing the Checksum SDK and providing a test account. Start generating tests in less than an hour.
