Detox _ Failed to type string because keyboard was

Question

I'm trying to test my react-native app using detox, waiting for a text input to be visible and typing text in it. My spec JS file looks like this:

describe('FiestTest', () => {
  beforeEach(async () => {
    await device.reloadReactNative()
  })

  it('Login to a test account', async () => {
    // LoginPage: entering phone number moving to next page
    await expect(element(by.id('LoginPage-phoneInput'))).toBeVisible()
    await element(by.id('LoginPage-phoneInput')).typeText('<someNumber>')
  })
})

And the error I get is:

FiestTest
    1) Enter phone number and tap on button


  0 passing (15s)
  1 failing

  1) FiestTest Enter phone number and tap on button:
     Error: An action failed. Please refer to the error trace below.
Exception with Action: {
  "Action Name" : "Type '6219'",
  "Element Matcher" : "(((respondsToSelector(accessibilityIdentifier) && accessibilityID('ValidatePage-txtField')) && !(kindOfClass('RCTScrollView'))) || (kindOfClass('UIScrollView') && ((kindOfClass('UIView') || respondsToSelector(accessibilityContainer)) && ancestorThatMatches(((respondsToSelector(accessibilityIdentifier) && accessibilityID('ValidatePage-txtField')) && kindOfClass('RCTScrollView'))))))"
}

  }
]

I'm using the following tools:

And this is my podfile:

# Uncomment this line to define a global platform for your project
# platform :ios, '9.0'

target '<appName>' do
  # Uncomment this line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!

  # Pods for <appName>

  pod 'Firebase'
  pod 'Firebase/Core'
  pod 'Firebase/Analytics'
  pod 'Firebase/Messaging'

  pod 'Yoga', :path => '../node_modules/react-native/ReactCommon/yoga'
  pod 'React', :path => '../node_modules/react-native', :subspecs => [
    'RCTText',
    'RCTImage',
    'RCTNetwork',
    'RCTWebSocket',
  ]

  #target '<appName>-tvOSTests' do
  #  inherit! :search_paths
    # Pods for testing
  #end

  #target '<appName>Tests' do
  #  inherit! :search_paths
    # Pods for testing
  #end

end

#target '<appName>-tvOS' do
  # Uncomment this line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!

  # Pods for <appName>-tvOS

#  target '<appName>-tvOSTests' do
#    inherit! :search_paths
    # Pods for testing
#  end

#end

For now I'm just using a sleep command like bellow in order to give me time to manually insert the string. However, this should not be a permanent solution...

function sleep (ms) {
return new Promise(resolve => setTimeout(resolve, ms))
}

await sleep(milliseconds)
// what needs to happen after I manually enter the code

I've also commented in a Detox issue on GitHub, but was wondering if anyone has had the same experience and has found a solution here.

Thanks for your assistance in advance!

Answer 1

please checkout here: https://github.com/wix/detox/blob/master/docs/APIRef.ActionsOnElement.md

on typeText() method

Note: Make sure hardware keyboard is disconnected. Otherwise, Detox may fail when attempting to type text.

To make sure hardware keyboard is disconnected, open the simulator from Xcode and make sure Hardware -> Keyboard -> Connect Hardware Keyboard is deselected (or press ⇧⌘K).

Answer 2

You should run

await element(by.id('LoginPage-phoneInput')).tap();

before

await element(by.id('LoginPage-phoneInput')).typeText('<someNumber>')

Answer 3

I wasn't able to get get the software keyboard work consistently but .replaceText() did work pretty well for me. waitFor() was also very useful.
