About
ZeroStep is an AI-driven extension designed for the Playwright testing framework, aimed at changing how developers and QA teams approach end-to-end (E2E) automation. At its core, the tool introduces a unique ai() function that utilizes the reasoning capabilities of large language models like GPT-3.5 and GPT-4. This approach allows testers to move away from creating and maintaining CSS selectors or XPath locators. By using natural language instructions, ZeroStep interprets the intent of a test case at runtime, identifying the elements and actions needed to fulfill the request. The integration process requires an npm installation to include the library in a project. Once configured, the ai() function can be utilized within any standard Playwright test script. It handles a variety of interactions, from filling out multi-step forms with realistic data to navigating menu systems and performing content assertions. Because the AI evaluates the page content in real-time, it can manage variations in UI layout that typically cause traditional scripts to fail. This makes the resulting test suites more resilient, potentially reducing the time spent updating tests due to minor styling changes or DOM restructuring. ZeroStep is designed for software engineering teams and QA professionals seeking to implement a more flexible testing strategy. By abstracting the technical implementation details of a web page, it supports a Test-Driven Development (TDD) approach for E2E testing. Teams can write tests based on requirements before the front-end code is finalized, as the system relies on the intent of the action rather than the specific markup. This allows different stakeholders to understand test definitions without needing to read complex code, bridging the gap between human requirements and automated execution. What distinguishes ZeroStep from other automation tools is its specific integration with the Playwright library and its focus on a selector-free workflow. Unlike standalone platforms, ZeroStep functions within the existing development environment and CI/CD pipeline. It enables developers to maintain their current tools while using AI to simplify complex scenarios, such as interacting with CRM platforms or verifying search results. With both free and paid tiers, it provides a scalable option for teams ranging from individual developers to larger organizations managing extensive automation suites.
Pros & Cons
Eliminates brittle CSS and XPath selectors by using AI to interpret intent at runtime.
Dramatically reduces test maintenance by making scripts resilient to UI changes and markup updates.
Allows for natural language test writing, enabling faster creation of complex end-to-end scenarios.
Integrates seamlessly into existing Playwright setups via a standard npm package.
Offers a free tier with 500 function calls per month for individual developers or small projects.
Introduction of AI processing at runtime may lead to slower test execution speeds compared to native selectors.
Dependency on external LLM providers requires an active internet connection for all tests.
High-volume enterprise test suites may quickly exceed the 2,000-call limit on the base Team plan.
Functionality is currently tied specifically to the Playwright ecosystem, limiting use with other frameworks.
Use Cases
QA Engineers can automate legacy applications with messy or dynamic DOM structures without spending hours debugging selectors.
Agile Developers can write E2E tests for new features during the planning phase, ensuring requirements are met before the UI is finished.
DevOps Teams can implement more stable regression tests that do not fail due to minor CSS or layout shifts in the production environment.
Product Managers can define executable user journeys in plain text to verify that the final product meets specific business logic.

FAQs
What is the primary benefit of using ZeroStep over standard Playwright?
ZeroStep removes the reliance on CSS selectors or XPath locators, which are often the primary cause of test flakiness. By using AI to interpret plain-text commands at runtime, tests remain functional even when the underlying website markup or design changes.
How do I get started with ZeroStep in my current project?
You can install the library using the command 'npm i @zerostep/playwright -D' and then import the ai function into your Playwright test files. From there, simply pass your natural language instructions to the function alongside the page and test objects.
Which AI models does ZeroStep use to process instructions?
The tool utilizes GPT-3.5 and GPT-4 to power its ai() function. This allows for high-level reasoning and the ability to handle complex web interactions that standard automation tools struggle with.
Is there a limit to how many people can use a single account?
Both the Free and Team plans offer support for unlimited users. The primary difference between the tiers is the number of ai() function calls allowed per month, ranging from 500 in the Free tier to 2,000 in the Team tier.
Can I use ZeroStep for asserting page content?
Yes, the ai() function can be used for both actions and assertions. For example, you can command it to 'Verify that a calendar is displayed' or 'Verify the number of labels in a repo' within your test script.
