Tests throw an exception #432

expilu · 2020-07-23T08:39:24Z

🐛 Bug Report

The plugin throws an exception when doing tests with testWidgets. The tests don't fail as the exception is thrown after it completes. But it leaves a lot of console spam like this:

`══╡ EXCEPTION CAUGHT BY FLUTTER TEST FRAMEWORK ╞════════════════════════════════════════════════════
The following MissingPluginException was thrown running a test (but after the test had completed):
MissingPluginException(No implementation found for method getDatabasesPath on channel
com.tekartik.sqflite)

When the exception was thrown, this was the stack:

Expected behavior

To not throw an exception when used on tests.

Reproduction steps

Just add a CachedNetworkImage to a widget and write a test for it with testWidgets.

In my case, the test fails.

Maybe because I'm doing golden testing.

await expectLater(
  find.byType(MyWidgetUsingCachedNetWorkImage),
  matchesGoldenFile('main.png'),
);

kjuchnowicz · 2020-08-12T13:26:18Z

I have exact same problem with widget tests while using CachedNetworkImage widget.

followed that blog post but still getting issue, seems base class is trying to create http client.

  Tried calling: printOnFailure("Warning: At least one test in this suite creates an HttpClient. When\nrunning a test suite that uses TestWidgetsFlutterBinding, all HTTP\nrequests will return status code 400, and no network request will\nactually be made. Any test expecting a real network connection and\nstatus code will fail.\nTo test code that needs an HttpClient, provide your own HttpClient\nimplementation to the code under test, so that your test can\nconsistently provide a testable response to the code under test.")
  package:test_api                                                            printOnFailure
  package:flutter_test/src/_binding_io.dart 83:7                              _MockHttpOverrides.createHttpClient
  dart:_http                                                                  new HttpClient
  package:http/src/io_client.dart 23:52                                       new IOClient
  package:http/src/io_client.dart 16:30                                       createClient
  package:http/src/client.dart 35:23                                          new Client
  package:flutter_cache_manager/src/web/file_service.dart 24:38               new HttpFileService
  package:flutter_cache_manager/src/web/web_helper.dart 24:39                 new WebHelper
  package:flutter_cache_manager/src/cache_manager.dart 91:31                  new BaseCacheManager
  custom_cache_manager.dart 9:9                                               new TestCacheManager

hmm seems to work if add the GetIt call inside a setUpAll method in the test. Still having test hang however but suspect that is probably due to using it with golden_toolkit.

I have exact same problem with widget tests while using CachedNetworkImage widget.

me too.

naresh2052 · 2022-07-13T10:10:48Z

Because cached_network_image >=3.2.0 depends on flutter_cache_manager ^3.3.0 which depends on sqflite ^2.0.0+3, cached_network_image >=3.2.0 requires sqflite from hosted.
So, because app depends on both cached_network_image ^3.2.1 and sqflite from git, version solving failed.

i faced this error plz any one help me
