.fillInTextarea(propValue, eventTargetValue[, options]) => Page

Fill in a textarea

Default Checked Props: id, name, and placeholder

Arguments

The propValue and options arguments are passed to .findWrapperForFillInTextarea to find a ReactWrapper. The ReactWrapper will be used to simulate events.

1. propValue (String): Value is compared with the values of the checked props to assert a match.
2. eventTargetValue (String): Value which will equal event.target.value in onChange event handlers triggered by the simulated change event.
3. options (Object): Optional.

• propToCheck (String): Name of prop to check against instead of the default checked props.

Returns

Page object which invoked the method. This allow the method to be chained with another Page object method.

Simulated Events

If a ReactWrapper is found by .findWrapperForFillInTextarea, then the following events will be simulated on the ReactWrapper's React element:

1. blur event on the React element which is focused. This will occur if there is a focused React element and it is not the same as the ReactWrapper's React element.
2. focus event on the ReactWrapper's React element unless it is already in focus.
3. change event on the ReactWrapper's React element. For onChange event handlers triggered by this simulated change event, event.target.value will equal eventTargetValue.

If no ReactWrapper is found, then an error is thrown.

Example in Jest

import React, { Component } from 'react'
import Page from 'react-page-object'

class App extends Component {
  state = { text: '' }

  onChange = event => this.setState({ text: event.target.value })

  render() {
    return (
      <div>
        {this.state.text}
        <textarea id="textarea-id" onChange={this.onChange} />
        <textarea name="textarea-name" onChange={this.onChange} />
        <textarea placeholder="textarea-placeholder" onChange={this.onChange} />
        <textarea className="textarea-class" onChange={this.onChange} />
      </div>
    )
  }
