Why does my Ember component integration test pass when I run it in isolation, but fail when I run the full suite?


I have a simple, bare-bones integration test for a component which depends on an i18n service (which the test injects). The component itself is a simple select dropdown from ember-select-list, with a default value of Select Language. Here's the test:

import { moduleForComponent, test } from 'ember-qunit';
import hbs from 'htmlbars-inline-precompile';

moduleForComponent('language-select', 'Integration | Component | language select', {
  integration: true,
  beforeEach() {
    this.inject.service('i18n');
  }
});

test('it renders', function(assert) {
  this.render(hbs`{{language-select}}`);

  assert.equal(this.$().text().trim().includes('Select Language'), true);
});

When I attempt to just run this one test file (i.e. ember test -f "language-select"), the output I see indicates that only linting tests were performed:

[ hospitalrun-frontend ] $ ember test -f "language-select"

However when I run a plain ember test, I see that this test fails because I am apparently injecting the i18n service incorrectly:

I don't see anything in the documentation here about the filter flag affecting the type of tests that are run (i.e. lint vs non-lint tests).

I'm happy to post a separate question about how to properly inject the i18n service, but my question here is:

Why does adding the filter flag result in only filtering tests being run?


Solution

  • It filters module names, not file names. You have dash inside a filter string. Remove it and use space instead:

    ember test -f "language select"
