Cypress’s EZ-USB® FX2LP™ (CY7C68013A/14/15/16A) is a low power, highly integrated USB 2.0 microcontroller. FX2LP has a fully configurable General Programmable Interface (GPIF™) and master/slave endpoint FIFO (8-bit or 16-bit data bus), which provides an easy and glueless connection to popular interfaces such as ATA, UTOPIA, EPP, PCMCIA, DSP, and most processors. Cypress Enables Portable Device Connectivity in Cars with Two Automotive-Qualified USB Devices Last Updated: SAN JOSE, Calif., September 21, 2009 – Cypress Semiconductor Corp. (NYSE: CY), the market leader in USB, today announced it has expanded its automotive-grade portfolio with two USB devices—the EZ-USB®-HX2LP 4-port high. A mobile phone, known as a cell phone in North America, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN).

Is Cypress free and open source?

The Test Runner is a free, downloadable and open source (MIT license) application. This is always free to use. Our Dashboard Service is a web application that offers a variety of billing plans (including a free, open source plan) for when you want to record your test runs in CI.

Please see our Pricing Page for more details.

What operating systems do you support?

You can install Cypress on Mac, Linux, and Windows. For additional information, please see our System requirements.

Do you support native mobile apps?

Cypress will never be able to run on a native mobile app, but we can test some functionality of mobile web browsers and test mobile applications that are developed in a browser, such as with the Ionic framework.

Currently you can control the viewport with the cy.viewport() command to test responsive, mobile views in a website or web application. You can also mimic certain behaviors like swiping using custom commands.

You can read about testing mobile applications with Ionic and Cypress here and see how we manage testing the mobile viewport in the Cypress Real World App.

How is this different from ‘X’ testing tool?

The Cypress Test Runner is a hybrid application/framework/service all rolled into one. It takes a little bit of other testing tools, brings them together and improves on them.

Mocha

Mocha is a testing framework for JavaScript. Mocha gives you the it, describe, beforeEach methods. Cypress isn’t different from Mocha, it actually uses Mocha under the hood. All of your tests will be written on top of Mocha’s bdd interface.

Karma

A unit testing runner for JavaScript, Karma, works with either Jasmine, Mocha, or any other JavaScript testing framework.

Karma also watches your JavaScript files, live reloads when they change, and is also the reporter for your tests failing / passing. It runs from the command line.

Cypress essentially replaces Karma because it does all of this already and much more.

Capybara

The Ruby specific tool that allows you to write integration tests for your web application is Capybara. In the Rails world, this is the go-to tool for testing your application. It uses Sauce Labs (or another headless driver) to interact with browsers. Its API consists of commands that query for DOM elements, perform user actions, navigate around, etc.

Cypress essentially replaces Capybara because it does all of these things and much more. The difference is that instead of testing your application in a GUI-less console, you would see your application at all times. You’d never have to take a screenshot to debug because all commands instantly provide you the state of your application while they run. Upon any command failing, you’ll get a human-readable error explaining why it failed. There’s no “guessing” when debugging.

Oftentimes Capybara begins to not work as well in complex JavaScript applications. Additionally, trying to TDD your application is often difficult. You often have to resort to writing your application code first (typically manually refreshing your browser after changes) until you get it working. From there you write tests, but lose the entire value of TDD.

Protractor

Using Protractor provides a nice Promise-based interface on top of Selenium, which makes it less complicated to deal with asynchronous code. Protractor comes with all of the features of Capybara and essentially suffers from the same problems.

Cypress replaces Protractor because it does all of these things and much more. One major difference is that Cypress enables you to write your unit tests and integration tests in the same tool, as opposed to splitting up this work across both Karma and Protractor.

Also, Protractor is very much focused on AngularJS, whereas Cypress is designed to work with any JavaScript framework. Protractor, because it’s based on Selenium, is still pretty slow, and is prohibitive when trying to TDD your application. Cypress, on the other hand, runs at the speed your browser and application are capable of serving and rendering; there is no additional bloat.

Do you support X language or X framework?

Any and all. Ruby, Node, C#, PHP - none of that matters. Cypress tests anything that runs in the context of a browser. It is back end, front end, language and framework agnostic.

You’ll write your tests in JavaScript, but beyond that Cypress works everywhere.

Can I run Cypress on another browser other than Chrome?

You can read about our currently available browsers here.

Will Cypress work in my CI provider?

Cypress works in any CI provider.

Does Cypress require me to change any of my existing code?

No. But if you’re wanting to test parts of your application that are not easily testable, you’ll want to refactor those situations (as you would for any testing).

Does Cypress use Selenium / Webdriver?

No. In fact Cypress’ architecture is very different from Selenium in a few critical ways:

Cypress runs in the context of the browser. With Cypress it’s easier to inspect what is running in the browser, but harder to talk to the outside world. In Selenium it’s the exact opposite. Selenium runs outside of the browser where your application is running (though Cypress is adding more commands every day that give you access to the outside world - like cy.request(), cy.exec(), and cy.task()).
With Selenium you get either 100% simulated events (with Selenium RC) or 100% native events (with Selenium WebDriver). With Cypress, you get both. For the most part we use simulated events. However we do use automation APIs for things like Cookies where we extend outside of the JavaScript sandbox and interact with the underlying browser APIs. This gives us flexibility to determine which type of event to use in specific situations. Native event support is on our roadmap.

If Cypress runs in the browser, doesn’t that mean it’s sandboxed?

Yes, technically; it’s sandboxed and has to follow the same rules as every other browser. That’s actually a good thing because it doesn’t require a browser extension, and it naturally will work across all browsers (which enables cross browser testing).

But Cypress is actually way beyond a basic JavaScript application running in the browser. It is also a desktop application and communicates with back end web services.

All of these technologies together are coordinated and enable Cypress to work, which extends its capabilities far outside of the browser sandbox. Without these, Cypress would not work at all. For the vast majority of your web development, Cypress will work fine, and already does work.

We use WebSockets; will Cypress work with that?

Yes.

We have the most complex most outrageous authentication system ever; will Cypress work with that?

If you’re using some complex thumb-print, retinal-scan, time-based, key-changing, microphone, audial, decoding mechanism to log in your users, then no, Cypress won’t work with that. But seriously, Cypress is a development tool, which helps you test your web applications. If your application is doing 100x things to make it extremely difficult to access, Cypress won’t magically make it any easier.

Because Cypress is a development tool, you can always make your application more accessible while in your development environment. If you want, disable complex steps in your authentication systems while you’re in your testing environment. After all, that’s why we have different environments! Normally you already have a development environment, a testing environment, a staging environment, and a production environment. So expose the parts of your system you want accessible in each appropriate environment.

In doing so, Cypress may not be able to give you 100% coverage without you changing anything, but that’s okay. Use different tools to test the less accessible parts of your application, and let Cypress test the other 99%.

Remember, Cypress won’t make a non-testable application suddenly testable. It’s on your shoulders to architect your code in an accessible manner.

Is it possible to use cypress on `.jspa`?

Yes. Cypress works on anything rendered to a browser.

Can I use Cypress to script user-actions on an external site like `gmail.com`?

No. There are already lots of tools to do that. Using Cypress to test against a 3rd party application is not its intended use. It may work but will defeat the purpose of why it was created. You use Cypress while you develop your application, it helps you write your tests.

Is there code coverage?

There is a plugin and detailed documentation on how to get end-to-end, unit and full stack code coverage.

Read our Code Coverage guide
Use the @cypress/code-coverage plugin

You may also find the following resources helpful when writing end-to-end tests:

Are there driver bindings in my language?

Cypress does not utilize WebDriver for testing, so it does not use or have any notion of driver bindings. If your language can be somehow transpiled to JavaScript, then you can configure Cypress webpack preprocessor or Cypress Browserify preprocessor to transpile your tests to JavaScript that Cypress can run.

What resources do you recommend to learn JavaScript before writing Cypress tests?

We hope that Cypress makes test writing simple and fun, even for people with a minimal knowledge of JavaScript. If you would like to develop your JS skills, we recommend the following free online resources:

Online tutorial Learn Javascript with small exercises
Book Eloquent JavaScript
Book Human JavaScript
an entire collection of free JavaScript books at the Free Frontend site
The Modern JavaScript Tutorial teaches you both JavaScript and HTML programming, and is available in several translations

So what benefits would one get for converting one’s unit tests from Karma or Jest to Cypress?

Unit tests are not something we are really trying to solve right now. Most of the cy API commands are useless in unit tests. The biggest benefit of writing unit tests in Cypress is that they run in a browser, which has debugger support built in.

We have internally experimented at doing DOM based component unit testing in Cypress - and that has the possibility of being an excellent “sweet spot” for unit tests. You’d get full DOM support, screenshot support, snapshot testing, and you could then use other cy commands (if need be). But as I mentioned this isn’t something we’re actively pushing; it remains a thing that’s possible if we wanted to go down that route.

With that said - we actually believe the best form of testing in Cypress is a combination of a “unit test” mixed with an “e2e test”. We don’t believe in a “hands off” approach. We want you to modify the state of your application, take shortcuts as much as possible (because you have native access to all objects including your app). In other words, we want you to think in unit tests while you write integration tests.

When should I write a unit test and when should I write an end-to-end test?

We believe unit tests and end-to-end tests have differences that should guide your choice.

Unit tests	End-to-end tests
Focus on code	Focus on the features
Should be kept short	Can be long
Examine the returned result of actions	Examine side effect of actions: DOM, storage, network, file system, database
Important to developer workflow	Important to end user’s workflow

In addition to the above differences, below are a few rules of thumb to decide when to write a unit test and when to write an end-to-end test.

If the code you are trying to test is called from other code, use a unit test.
If the code is going be called from the external system, like a browser, use an end-to-end test.
If a unit test requires a lot of mocking and you have to bring tools like jsdom, enzyme, or sinon.js to simulate a real world environment, you may want to rewrite it as an end-to-end test.
If an end-to-end test does not go through the browser and instead calls the code directly, you probably want to rewrite it as a unit test

Finally, unit and end-to-end tests are not that different and have common features. Good tests:

Focus on and test only one thing.
Are flake-free and do not fail randomly.
Give you confidence to refactor code and add new features.
Are able to run both locally and on a continuous integration server.

Certainly, unit and end-to-end tests are NOT in opposition to each other and are complementary tools in your toolbox.

How do I convince my company to use Cypress?

First, be honest with yourself - is Cypress the right tool for your company and your project? We believe that the best approach is a “bottoms up” approach, where you can demonstrate how Cypress solves your company’s particular needs. Implement a prototype with your project to see how it feels. Test a couple of common user stories. Identify if there are any technical blockers. Show the prototype to others before proceeding any further. If you can demonstrate the benefits of using Cypress as a developer tool for your project to other engineers, then Cypress will likely be more quickly adopted.

How can I find out about new versions of Cypress?

We publish our releases at GitHub and Npm, together with the releases we also publish a changelog with the principal changes, fixes, and updates.
You can follow through these links:

How often are Cypress Test Runner versions released?

We schedule releases of the Test Runner on Monday every two weeks. This new version includes any bugfixes and/or features that have been completed by that time.

We schedule major releases with breaking changes approximately every 3 months.

If there is a significant bug outside of our release schedule then we release a patch as soon as possible.

Windows versions

Windows 10 for desktop editions (Home, Pro, Enterprise, and Education)
Windows 10 Mobile

Common points of discussion for OEMs who want to build Windows systems with USB Type-C connectors.

USB Type-C connector features

Symmetric and reversible design

The connector is symmetric. The cable has a USB Type-C connector on each end allowing the host and function device to use USB Type-C connectors. Here is an image that compares the connectors:
The connector is designed to be reversible. Traditional connectors had to be connected the 'right-side-up'. With the reversible design, the connector can be flipped.

Supports all USB device speeds

The connector can support USB devices that are low-speed, full-speed, high-speed, SuperSpeed (including SS+).

Alternate modes

The connector can support alternate modes. The alternate mode feature allows non-USB protocols to run over the USB cable, while simultaneously preserving USB 2.0 and charging functionality. Currently, the most popular alternate modes are DisplayPort/DockPort and MHL.

DisplayPort / DockPort

This alternate mode allows the user to project audio/video to external DisplayPort displays over a USB connector.

MHL

The MHL alternate mode is allows the user to project video/audio to external displays that support MHL.

Billboard error messages

If a user connects a USB Type-C alternate mode device or adapter that is not supported by the attached PC or phone, the device or adapter can expose a Billboard device that contains information about the error condition to help the user troubleshoot issues.

Increased power limits

A system with USB Type-C connectors has higher power limits, it can support up to 5V, 3A, 15W.

In addition, the connector can optionally support the power delivery feature as defined by the USB Power Delivery OEM . If the connector supports power delivery, a USB Type-C system can be a power source provider or a consumer and support up to 100W.

Supports USB dual roles

Peripheral devices can connect to a mobile system with USB Type-C connectors, changing the traditional role of a mobile system from function to host. When the same system is connected to a PC, the system resumes the role of a function and PC becomes the host.

Operating system input into which alternate mode needs to be negotiated, such as DP 2-lane vs. DP 4-lane

No. The operating system (or any Microsoft-provided software component) plays no part in selecting an alternate mode. The decision is made by the driver for the connector, specifically the USB connector manager (UCM) client driver. The driver does so by communicating with the connector's firmware by using hardware interfaces.

Pre-OS charging with Type-C and PD

Enabling pre-OS charging is owned by the OEM. You can choose to not implement USB Power Delivery, and charge at USB Type-C power levels until you boot into the operating system.

Charging the phone when it is a USB host to enable docking scenarios like Continuum

Here are a few things to consider:

You must to implement USB Power Delivery, so that power and data roles can be swapped independently.
Your dock’s upstream port should be implemented as a Charging UFP, defined in the USB Type-C specification. For details, see section 4.8.4, version 1.1.
Your dock should request a DR_Swap if it resolved to a DFP, or a PR_Swap if it resolved to a UFP.
The initial DFP is the power source, so you must change the data role. The initial UFP is the power sink, so you must change the power role. You can perform those operations in your implementation of these callback functions:

Windows 10 Mobile support of USB billboard devices

Yes, if you connect the phone to a device that supports a USB Billboard, as per the USB Device Class Definition for Billboard Devices specification, the user is notified. Your USB connector manager (UCM) client driver is not required to handle the notification. If your system does not recognize the alternate mode, do not enter the mode.

Support for USB Type-C on earlier versions of Windows

USB Type-C is not supported on versions of Windows prior to Windows 10.

UCSI support on earlier versions of Windows

UCSI is not supported on versions of Windows prior to Windows 10.

How to test an implementation of UCSI

To test your implementation, follow the guidelines given in USB Type-C manual interoperability test procedures. We recommend running USB tests in Windows Hardware Lab Kit (HLK) for Windows 10. These tests are listed in Windows Hardware Certification Kit Tests for USB.

Conditions and UI for the different errors

Windows 10 can show a set of USB Type-C error messages to help educate users about the limitations with different combinations of USB Type-C hardware and software. For example, the user might get 'Device is charging slowly' message if the charger connected to the USB Type-C connector is not powerful enough, not compatible with the system, or is connected to a non-charging port. For more information, see Troubleshoot messages for a USB Type-C Windows system.

Connecting a non-PD port to a PD provider and a PD consumer to a system that is not a PD provider

The non-PD port attempts to charge the system by using USB Type-C current levels. For more information, see USB 3.1 and USB Type-C specifications.

Connecting Thunderbolt, SuperMHL, or PCI express to a PC that does not support those capabilities

The alternate mode feature allows non-USB protocols (such as Thunderbolt, SuperMHL) to run over the USB cable, while simultaneously preserving USB 2.0 and charging functionality. If a user connects a USB Type-C alternate mode device or adapter that is not supported by the attached PC or phone running Windows 10, an error condition is detected and a message is shown to the user.

If the device or adapter exposes a Billboard device, the user sees information about the error condition to help the troubleshoot issues. Windows 10 provides an in-box driver for a Billboard device and notifies the user that an error has occurred.
The user might see an error notification, 'Try improving the USB connection'. For more information, see Fix USB-C Problems.

For the best results, make sure that the alternate mode device or adapter’s requirements are met by PC or phone or cable.

Support and limitations for MTP over USB Type-C in Windows

Windows 10 for desktop editions supports MTP in the initiator role; Windows 10 Mobile supports MTP in the responder role.

How downstream devices and hubs connect and communicate with USB Connector Manager (UCM)

UCM is its own device stack (see Architecture: USB Type-C design for a Windows system). Windows 10 support for USB Type-C includes the required plumbing to make sure that the different class drivers know how to communicate with the different USB Type-C connectors. In order to get Windows 10 support for USB Type-C, you must plug into the UCM device stack.

USB Type-C MUTT requirements for HLK tests

The Windows HLK for Windows 10 contains tests for USB host and function controllers. To test your system, use a USB C-A adapter. These tests are listed in Windows Hardware Certification Kit Tests for USB.

Microsoft support for P2P data transfer between the same Windows 10 SKU

This is not a valid connection.

You cannot connect two PCs running Windows 10 for desktop editions.
You cannot connect two mobile devices running Windows 10 Mobile.

If the user attempts to make such a connection, Windows shows an error message. For more information, see Error messages for a USB Type-C Windows system.

The only valid connection is between a Windows Mobile device and Windows desktop device.

UCM class extension (UcmCx) communication with PMIC or battery driver to get/set charging status

On software-assisted charging platforms, UcmCx communicates with PMIC and the battery subsystem. The client driver may determine the charging levels by communicating with the hardware through hardware interfaces. On hardware-assisted platforms, the embedded controller is responsible for charging. UcmCx takes no part in the process.

HLK support for USB Type-C

In Windows HLK for Windows 10, there are no USB Type-C specific tests. We recommend running USB tests in Windows HLK for Windows 10. These tests are listed in Windows Hardware Certification Kit Tests for USB.

UCSI

USB Type-C Connector System Software Interface (UCSI) Specification describes the capabilities of the USB Type-C Connector System software Interface (UCSI), and explains the registers and data structures, for hardware component designers, system builders, and device driver developers.

Microsoft provides an in-box driver with Windows, UcmUcsi.sys, that implements the features defined by the specification. This driver is intended for systems with embedded controllers.

Test a UCSI implementation running on Windows 10

We recommend running USB tests in Windows HLK for Windows 10. These tests are listed in Windows Hardware Certification Kit Tests for USB.

Test a UCMCx client driver on Windows 10

We recommend running USB tests in Windows HLK for Windows 10. These tests are listed in Windows Hardware Certification Kit Tests for USB.
