This page is for testing the Promises returned from adding keyboards. See Specification #5044.
This test page is best used with Developer mode, as output for both successes and failures will be logged to the JS console.
Visible alert-style feedback will only occur for invalid search terms, such as using "foobar" for any of the three keyboard-adding options at the bottom of the page.
You are currently testing under the internal alerts mode. Two alert modes are available: Disabled or Enabled (Default)
This will only affect whether or not KeymanWeb's alert modal is displayed. A native browser alert and dev-console error log will occur regardless of this setting when stub fetch errors occur.
This verifies adding a keyboard stub with languages Object and no filename
