I am using play framework activator and my tests are mostly running fake application with in memoory database (EBean ORM).
The tests are failing once to ~5 times with attached error which does not explain the reason and specific test name.
anyone familiar with this issue?
Failing test case:
public class ApplicationTest {
#Test
public void renderTemplate() {
Content html = views.html.index.render("Your new application is ready.");
assertEquals("text/html", contentType(html));
assertTrue(contentAsString(html).contains("Your new application is ready."));
}
}

I am using aspnetboilerplate 5.1.0.
In the ProjectName.Web.Tests I have run into a situation that I cannot solve.
I have set up web tests for my controller using [Fact] or [Theory].
When I attempt to run the tests using GetResponseAsString(string url, HttpStatusCode expectedStatusCode = HttpStatusCode.OK) found in the webtestbase class. All the tests fail.
Here is an example of my Test:
[Fact]
public async Task Index_Test()
{
//Act
var response = await GetResponseAsStringAsync(
GetUrl<HomeController>(nameof(HomeController.Index))
);
//Assert
response.ShouldNotBeNullOrEmpty();
}
The Tests all fail on this:
Message:
Shouldly.ShouldAssertException : response.StatusCode
should be
HttpStatusCode.OK
but was
HttpStatusCode.NotFound
I have other aspnetboilerplate projects in version 3.8.3 and 4.2.1 and the web tests work just fine. So I'm not sure why the server is not able to find the action methods on my controllers.
The service tests found in the ProjectName.Tests project run just fine.
I found the culprit. The problem I was experiencing was due to attempting to copy a project for web unit tests from one of the aspnetboilerplate project template repositories and updating all of the references and class names to match the names and namespaces in the destination VS solution.
I submitted a similar question on the aspnetboilerplate github account.
https://github.com/aspnetboilerplate/aspnetboilerplate/issues/5463.
Ultimately, here is what happened.
After going through the same process with a newer project. I found that In the
class file that would by default be named AbpProjectNameWebTestBase.cs in the method
protected override IWebHostBuilder CreateWebHostBuilder()
{
return base
.CreateWebHostBuilder()
.UseContentRoot(ContentRootFolder.Value)
.UseSetting(WebHostDefaults.ApplicationKey, typeof(AbpProjectNameWebModule).Assembly.FullName);
}
I mistakenly replaced AbpProjectNameWebModule with AbpProjectNameTestModule instead of AbpProjectNameWebMvcModule. This was trying to use the Application Service Unit test project as the web project. Therefore it could not find any of the referenced URI's and therefore returned httpStatusCode.NotFound.
After fixing this reference. I started getting exceptions that pertained to the public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory) method.
These were things like adding app.UseAuthentication() and app.UseAuthorization() as well as needing to add a Middleware to provide a ClaimsIdentity and ClaimsPrincipal for the context.User (i.e. app.UserMiddleware<TestAuthenticationMiddleware>())
Now, I am able to get my web unit tests to run as I had in previous versions.
Now, I am trying to develop a testing tool, which can make unit testing. I mean I want to use JUnit in my testing tool to test other projects. But I don't know how to insert JUnit into my testing tool. Is it possible to do that and how? And is there any other open-source testing tool can be inserted into my testing tool?
To use Junit API make sure you got the jar in the classpath
To use Junit tests you need the testing class to extend SystemTestCase4
and your function to have #Test annotation above it
if you want code to run before your test so use function with #Before
and if you want after use function with #After
public class BaseTest extends SystemTestCase4 {
#Before
public void beforeEachTest() throws Exception {
}
#Test
#TestProperties(name = "test test ")
public void testTest() throws Exception {
//run your tested code
}
#After
public void afterEachTest() throws Exception {
}
as for how to test your projects it depend what tests you want to do?
For unit testing just add your own tests inside the projects
Integration, Functional or other tests need you to understand how to "Attack" it, meaning if it's UI tests for web so use tools for that (Selenium for example) if it's for checking network so use JMeter
I'm trying to use the build-test-data plugin (v. 2.0.4) to build test data in a unit test of a Grails 2.1.4 application.
The app has the following domain classes
class Brochure {
static constraints = {}
static hasMany = [pageTags: PageTag]
}
class PageTag {
static constraints = {
}
static belongsTo = [brochure: Brochure]
}
Then in my unit test I try to build an instance of PageTag with
#Build([Brochure, PageTag])
class BrochureTests {
void testSomething() {
PageTag pageTag = PageTag.build()
}
}
But it fails with the error
groovy.lang.MissingMethodException: No signature of method:
btd.bug.Brochure.addToPageTags() is applicable for argument types:
(btd.bug.PageTag) values: [btd.bug.PageTag : (unsaved)] Possible
solutions: getPageTags()
My example looks exactly the same as that shown in the plugin's docs, so I've no idea why this isn't working. A sample app that demonstrates the issue is available here.
Fixed in version 2.0.5
I commented on the linked github issue, but this is because of a perf "fix" in how grails #Mock annotation works.
This change pretty much removes all of the linking code that made it possible for BTD to work in unit tests.
The only way around it currently is to also add an explict #Mock annotation for all of the domain objects in the part of the domain graph that's required to build a valid object.
The test code will be quicker with this change, which is great, but it puts a larger burden on the developer to know and maintain these relationships in their tests (which is what BTD was trying to avoid :).
I am currently building a web application using GWT, GWTP.
And I have some questions about testings:
Is there a Lint-like tool for GWTP or GWT?
How to test presenters? (GWTP with Mockito)
How to test views?
Thanks.
Presenters can be easily unit-tested using Jukito. Here's a quick example of a Presenter being tested using Jukito.
#RunWith(JukitoRunner.class)
public class ShowCommentsPresenterTest {
#Inject
private ShowCommentsPresenter showCommentsPresenter;
#Inject
private PlaceManager placeManager;
#Test
public void onReset_PlaceRequestHasNoShowId_ShouldHideView() {
//given
when(placeManager.getCurrentPlaceRequest()).thenReturn(new PlaceRequest());
//when
showCommentsPresenter.onReset();
//then
verify(showCommentsPresenter.getView()).hide();
}
#Test
public void onReset_PlaceRequestHasAShowId_ShouldDisplayView() {
//given
String someShowId = "12345";
when(placeManager.getCurrentPlaceRequest()).thenReturn(new PlaceRequest()
.with(ParameterTokens.getShowId(), someShowId));
//when
showCommentsPresenter.onReset();
//then
verify(showCommentsPresenter.getView()).display();
}
}
In GWTP's philosophy, Views should not be unit-tested directly. Using a dumb View that is a slave to the Presenter, most of the logic can be tested through unit tests on the Presenters. Tools like Selenium are a better fit for testing UI interactivity.
Google put out a great article about using different testing methodologies with GWT. Definitely check it out. Personally, I use JUnit when I'm testing back-end stuff like business logic, and Selenium for testing the UI and application as a whole from the browser's perspective.
I'm a .NET developer and I'm writing tests for my data access layer. I have tests that use fake repository - I have achieved that by using Moq and Ninject.
I'm getting my head around EntityFramework 4.1 Code First model and I'd like to create a prototype for CRUD routines. It's an MVC app, so my entities won't be tracked by a context.
To me it feels wrong that I'm writing tests that will make changes to the database. I will then have to clear the database each time I want to run these tests. Is this the only way to test CRUD routines?
Thank you
How do you expect to test data access if you don't access the data? Yes data access should be tested against real database. There is very simple workaround for your problem. Make your test transactional and rollback changes at the end of the test. You can use base class like this (NUnit):
[TestFixture]
public abstract class BaseTransactionalTest
{
private TransactionalScope _scope = null;
[SetUp]
public void Initialize()
{
_scope = new TransactionalScope(...);
}
[TearDown]
public void CleanUp()
{
if (_scope != null)
{
_scope.Dispose();
_scope = null;
}
}
}
