Cypress v4.6.0 Release Notes

Release Date: 2020-05-20 // 6 days ago
  • 🚀 Released 5/20/2020

    🔋 Features:

    • Errors in the Test Runner now display a code frame to preview where the failure occurred with the relevant file, line number, and column number highlighted. Clicking on the file link will open the file in your preferred file opener and highlight the line and column in editors that support it. Addresses #3762.
    • ⬆️ Cypress now utilizes source maps to enhance the error experience. Stack traces are translated so that your source files are shown instead of the generated file that is loaded by the browser. Cypress will include an inline source map in your spec file. If you modify the preprocessor, ensure that inline source maps are enabled to get the same experience. Users of @cypress/webpack-preprocessor should upgrade to v5.4.1 or later of the package which will correctly inline source maps. Addresses #881, #1761 and #3966.
    • 🔧 Cypress now enables AST-based JS/HTML rewriting when setting the experimentalSourceRewriting configuration option to true. Addresses #5273.
    • Number arguments passed to have.text, have.id, have.data, have.value, and have.attr assertions chainers are now automatically cast to strings for comparison. Addresses #7314.

    🛠 Bugfixes:

    • 0️⃣ Default TypeScript options are now set to module: commonJS which Node.js and the browser expect. This fixes a situation where setting a different module in a tsconfig.json would cause errors to throw if you had export, import or async keywords in your code. Fixes #7005, #7011, #7043, and #7151.
    • 🛠 When experimentalSourceRewriting is enabled, setting location or location.href to a relative href, or using location.replace or location.assign with a relative href will no longer navigate the AUT to the wrong URL. Fixes #3975 and #3994.
    • 🛠 When experimentalSourceRewriting is enabled, the use of window.top and window.parent will no longer cause the AUT to break out of the Cypress iframe. Fixes #5271 and #1467.
    • 🛠 When experimentalSourceRewriting is enabled, calls to window.frames, window.parent.frames, and other frames will no longer point to the wrong reference after being proxied through Cypress. Fixes #2664.
    • 🛠 When experimentalSourceRewriting is enabled, scripts using the integrity attribute for sub-resource integrity (SRI) will now load after being proxied through Cypress. Fixes #2393.
    • 🛠 When experimentalSourceRewriting is enabled, the use of document.location to set the URL will no longer navigate the AUT to the wrong URL. Fixes #7402.
    • 🛠 Type definitions will no longer conflict when running Cypress in a project with Jest. Fixes #3536.
    • 🛠 We increased the timeout for launching Firefox from 2.5 seconds to 50 seconds. Previously, users hitting this limit would encounter a "cannot open socket" error; now, the error will be wrapped. Fixes #7159.
    • 🛠 .click will now click in the correct coordinates when either x or y coordinate options are zero. Fixes #7319.
    • 💻 Cypress no longer displays onError is not a function when a browser can't connect. Fixes #7217.
    • You can now pass the force: true option to .select() to select options within a disabled <select>. Addresses #107.
    • 🛠 We now throw an error when attempting to .select() an <option> within a disabled <optgroup>. Fixes #7226.
    • 🛠 We fixed a regression in 4.3.0 where the message output during errors were not formatted correctly. Fixes #6924.
    • Using Cypress._.capitalize now correctly behaves the same as Lodash's capitalize method. Fixes #7222.
    • ✅ When experimentalComponentTesting is enabled, clicking on a component spec now watches the correct file without assuming it is an integration file. Fixes #7244.
    • 🛠 Firefox video recording no longer crashes Cypress when running very short spec files. Fixes #6408.
    • 🛠 Applications containing a DOM element with an id attribute containing 'jquery' will no longer throw an error during cy.visit(). Fixes #6193.
    • ✅ Long errors generated when compiling or bundling the test file are now horizontally scrollable. Fixes #6898.

    Misc:

    • ⚠ Cypress no longer requires write access to the root of the project, it instead will display a warning when no write access is given. Addresses #1281.
    • ⏱ We increased the timeout for launching Chrome from 20 seconds to 50 seconds. Addressed in #7372.
    • 🍎 We increased the timeout for macOS or Linux to exit from a --version command when looking for available browsers from 5 seconds to 30 seconds. Addressed in #7366.
    • 💻 We improved error handling when Cypress launches Chromium-family browsers. Addresses #6518.
    • We now export Cypress.ConfigOptions types as a partial of the full options interface. Addresses #7238.
    • We're continuing to make progress in converting our codebase from CoffeeScript to JavaScript. Addresses #2690 in #7162, #7216, #7227, #7320, #7232, and #7345.
