提交表单后，编写 Ember Octane 组件测试以检查 state 是否正确？

Question

I want to write a test such that when I submit a string, then a @tracked array =[0,0,0] field will change. I have a simple <Textarea @value={{ input0 }} ></Textarea> for hbs.
if input is 1 then the tracked array becomes [0,1,0] . How do I do this?? So far I have the following code that DOESN'T work:

import { module, test } from 'qunit';
import { setupRenderingTest } from 'ember-qunit';
import { click, render } from '@ember/test-helpers';
import hbs from 'htmlbars-inline-precompile';

module('Integration | Component | array', function(hooks) {
    setupRenderingTest(hooks);



    test('Textarea should display PLACE [0,1,0]"', async function(assert) {

        await render(hbs`<Array />`);
        assert.equal(find('textarea').value, 'testing"')
      });

});

Welcome to Stack Overflow!

It looks like you are being trolled by window.find , which isn't what you want, you need find from @ember/test-helpers .

Replace:

import { click, render } from '@ember/test-helpers';

with:

import { click, find, render } from '@ember/test-helpers';

Good Luck!
