[01] Facts

At a glance

Cypress Cloud plans and included test results sit on cypress.io/pricing. The docs at docs.cypress.io cover browser support, trade-offs, and component testing, and the license sits in the GitHub repository.

[02] Authoring

The same test, both ways

Both panels describe one guest checkout. The Cypress spec holds twelve cy.get() calls and one hand-tuned timeout. The TesterArmy version holds seven sentences and no selector.

[03] Differences

Where they differ

Cypress executes cy.* commands inside the browser against selectors your team maintains. TesterArmy's agent reads each plain-English step, looks at the page, and does what a user would do.

Selectors you keep current

Cypress finds elements through cy.get() selectors and cy.contains() text you write and update after markup changes. TesterArmy reads the rendered screen and needs no selector.

Waiting and retries

Cypress retries queries and assertions for four seconds by default, and teams tune timeouts per command. TesterArmy's agent waits on its own.

Coverage beyond the browser

Cypress runs inside a browser, and its docs list native and mobile events as unsupported. TesterArmy also runs on iOS simulators and Android emulators.

Environment stops kept apart

Cypress marks a test failed whether staging was down or the product broke. TesterArmy separates environment stops from product failures, with the reason attached.

[04] Comparison

Side by side

Cypress gives engineers time travel snapshots for every command, automatic retries, and a large plugin ecosystem. The rows below weigh those against selector upkeep and mobile coverage.

Who should pick which

Both tools can share a repository. Cypress keeps the component tests and stubbed flows, and TesterArmy takes the end-to-end journeys and native mobile.

[07] FAQ

Questions

Cypress is a JavaScript framework. Your team writes cy.* command chains with selectors and the runner executes them inside a browser. TesterArmy is a service whose agent takes plain-English steps and operates a browser or mobile simulator itself.

On the end-to-end layer it is. TesterArmy covers the same user journeys without selectors and adds native iOS and Android. Component tests with cy.mount and cy.intercept() stubbing have no equivalent, so those stay in Cypress.

The Cypress app costs nothing under MIT. Cypress Cloud is free to 500 results a month, Team starts at $67 a month billed annually, and Enterprise is quoted. TesterArmy starts free; Hobby is $99 a month and includes 250 runs.

It does not. Cypress runs inside a browser, and its trade-offs page says there is no native or mobile event support, so a native app needs a second tool. TesterArmy runs those same sentences on iOS simulators and Android emulators.

Debugging and scope are where Cypress wins. Time travel shows a snapshot for every command, Developer Tools work in the same window, and cy.intercept() stubs any network call. Component tests for React, Angular, and Vue live in the same runner.

One prompt in your coding agent covers most of the move. It reads cypress.config and the specs, turns each it() into act, assert, and login steps, and verifies each with the CLI. The /migrate/cypress playbook lists what stays behind.
