Taking Screenshots

It is possible to take screenshots when testing Visual Studio Code extensions. Screenshot can be captured by calling:

VSBrowser.instance.takeScreenshot(basename: string)

Captured screenshots will be saved in screenshots folder which can be found in a test storage folder ($TMPDIR/test-resources by default). File name will be generated from given basename in the following format: ${basename}.png.

Mocha integration

Tester takes screenshots on all failed test cases. Screenshot name is determined by calling this.currentTest.fullTitle(). This feature does not apply to Mocha hooks by default. In order to capture screenshots on failed hooks, one must import vscode-extension-tester hook.

// Supported hooks: before, beforeEach, after and afterEach
import { before } from "vscode-extension-tester";
