Мы стремимся сохранить кодовое покрытие Electron высоким. We ask that all pull request not only pass all existing tests, but ideally also add new tests to cover changed code and new scenarios. https://crowdin.com/translate/electron/159/en-ru#13105.
To ensure that your changes are in compliance with the Electron coding style, run
npm run lint, which will run a variety of linting checks against your changes depending on which areas of the code they touch.
Many of these checks are included as precommit hooks, so it's likely you error would be caught at commit time.
If you are not using build-tools, ensure that the name you have configured for your local build of Electron is one of
Default, or you have set
process.env.ELECTRON_OUT_DIR. Without these set, Electron will fail to perform some pre-testing steps.
To run all unit tests, run
npm run test. The unit tests are an Electron app (surprise!) that can be found in the
spec folder. Note that it has its own
package.json and that its dependencies are therefore not defined in the top-level
To run only specific tests matching a pattern, run
npm run test --
-g=PATTERN, replacing the
PATTERN with a regex that matches the tests you would like to run. As an example: If you want to run only IPC tests, you would run
npm run test -- -g ipc.
Node.js Smoke Tests
If you've made changes that might affect the way Node.js is embedded into Electron, we have a test runner that runs all of the tests from Node.js, using Electron's custom fork of Node.js.
To run all of the Node.js tests:
$ node script/node-spec-runner.js
To run a single Node.js test:
$ node script/node-spec-runner.js parallel/test-crypto-keygen
where the argument passed to the runner is the path to the test in the Node.js source tree.
Проверка на устройствах Windows 10
Extra steps to run the unit test:
Visual Studio 2019 must be installed.
Node headers have to be compiled for your configuration.
ninja -C out\Testing third_party\electron_node:headers
The electron.lib has to be copied as node.lib.
copy electron.lib gen\node_headers\Release\node.lib
На некоторых устройства на Windows 10 может быть не установлен шрифт Meriyo, что может привести к провалу fallback теста. Для того чтобы установить шрифт Meiryo:
- Нажмите кнопку Windows и найдите Управление дополнительными функциями.
- Нажмите Добавить функцию.
- Выберите Японские дополнительные шрифты и нажмите Установить.
Some tests which rely on precise pixel measurements may not work correctly on devices with Hi-DPI screen settings due to floating point precision errors. To run these tests correctly, make sure the device is set to 100% scaling.
To configure display scaling:
- Push the Windows key and search for Display settings.
- Under Scale and layout, make sure that the device is set to 100%.
