A little help trying to set text on a react native TextInput


I’m trying to set text on a react-native TextInput but everytime Appium gives me a null object reference.

The react-native component:

My tests are in nightwatch js: browser.elementIdValue(‘Email’, ‘test’);

Appium server log:

[HTTP] → POST /wd/hub/session/71a7fab0-09dc-4a0b-9ad9-9965cc904e60/element/Ema
il/value {“value”:[“t”,“e”,“s”,“t”]}

I was thinking that maybe appium could not be finding the element ID but then why would this command: browser…expect.element(‘Email’, ‘id’).to.be.present; works 100%?

Thank you for the help.

Assuming that u are trying to input something into your inputBox, my 2 cents:

  1. Use uiautomator (and take a snapshot of screen containg the input box)
  2. Now u can find xpath of your inputbox
    In my case, this is what helped me
    browser.elementByXPath(<your inputBox’s xpath>).type(‘some text’)
    BTW, M using nodejs . Make suitable changes for ur case
