To use .net 6 you need to update the Omnisharp setting to use the 'modern' way

the setting you need to toggle is omnisharp.useModernNet. it is described in the reads of the C# extension.

Deps File Missing for Dotnet 6 Integration Tests

Asked 2022-Feb-17 at 21:19

Before I start, I've tried all suggestions from the following and none work:

Integration testing ASP.NET Core with .NET Framework - can't find deps.json

https://zimmergren.net/unable-to-find-deps-json-dotnet-azure-devops/

So I'm trying to write some integration tests for dotnet 6. However, my WebApplicationFactory throws the following error:

System.InvalidOperationException: Can't find '/repos/subscription-info-api/tests/SubscriptionInfoApi.Tests.Integration/bin/Debug/net6.0/...

System.InvalidOperationException Can't find '/repos/subscription-info-api/tests/SubscriptionInfoApi.Tests.Integration/bin/Debug/net6.0/testhost.deps.json'. This file is required for functional tests to run properly. There should be a copy of the file on your source project bin folder. If that is not the case, make sure that the property PreserveCompilationContext is set to true on your project file. E.g 'true'. For functional tests to work they need to either run from the build output folder or the testhost.deps.json file from your application's output directory must be copied to the folder where the tests are running on. A common cause for this error is having shadow copying enabled when the tests run. at Microsoft.AspNetCore.Mvc.Testing.WebApplicationFactory1.EnsureDepsFile() at Microsoft.AspNetCore.Mvc.Testing.WebApplicationFactory1.EnsureServer() at Microsoft.AspNetCore.Mvc.Testing.WebApplicationFactory1.CreateDefaultClient(DelegatingHandler[] handlers) at Microsoft.AspNetCore.Mvc.Testing.WebApplicationFactory1.CreateDefaultClient(Uri baseAddress, DelegatingHandler[] handlers) at Microsoft.AspNetCore.Mvc.Testing.WebApplicationFactory1.CreateClient(WebApplicationFactoryClientOptions options) at Microsoft.AspNetCore.Mvc.Testing.WebApplicationFactory1.CreateClient() at SubscriptionInfoApi.Tests.Integration.UnitTest1.Test1() in /repos/subscription-info-api/tests/SubscriptionInfoApi.Tests.Integration/UnitTest1.cs:line 14 at SubscriptionInfoApi.Tests.Integration.UnitTest1.Test1() in /repos/subscription-info-api/tests/SubscriptionInfoApi.Tests.Integration/UnitTest1.cs:line 16 at Xunit.Sdk.TestInvoker1.<>c__DisplayClass48_0.<b__1>d.MoveNext() in /_/src/xunit.execution/Sdk/Frameworks/Runners/TestInvoker.cs:line 264 --- End of stack trace from previous location --- at Xunit.Sdk.ExecutionTimer.AggregateAsync(Func1 asyncAction) in //src/xunit.execution/Sdk/Frameworks/ExecutionTimer.cs:line 48 at Xunit.Sdk.ExceptionAggregator.RunAsync(Func`1 code) in //src/xunit.core/Sdk/ExceptionAggregator.cs:line 90

QUESTION

Observable with backpressure in C#

Asked 2022-Jan-13 at 12:01

Is there a way in C# rx to handle backpressure? I'm trying to call a web api from the results of a paged query. This web api is very fragile and I need to not have more than say 3 concurrent calls, so, the program should be something like:

Feth a page from db
Call the web api with a maximum of three concurrent calls per each record on the page
Save the results back to db
Fetch another page and repeat until there are no more results.

I'm not really getting the sequence that I'm after, basically the db gets all the records regardless of whether they can be processed or not.

I've tried a variety of things including tweaking at the ObserveOn operator, implementing a semaphore, and a few other things. Could I get a little bit of guidance to implement something like this?

...

ANSWER

Answered 2022-Jan-13 at 12:01

The Rx does not support backpressure, so there is no easy way to fetch the records from the DB at the same tempo that the records are processed. Maybe you could use a Subject as a signaling mechanism, push a value every time a record is processed, and devise a way to use these signals at the producing site to fetch a new record from the DB when a signal is received. But it will be a messy and idiomatic solution. The TPL Dataflow is a more suitable tool than the Rx for doing this kind of work. It supports natively the BoundedCapacity configuration option.

Some comments regarding the code you've posted, that are not directly related to the backpressure issue:

The Merge operator with a maxConcurrent parameter imposes a limit on the concurrent subscriptions to the inner sequences, but this will have no effect in case the inner sequences are already up and running. So you have to ensure that the inner sequences are cold, and a handy way to do this is the Defer operator:

QUESTION

How to compare file paths from JsonConfigurationSources and Directory.GetFiles properly?

Asked 2021-Dec-20 at 04:22

I created an extension method to add all JSON configuration files to the IConfigurationBuilder

...

ANSWER

Answered 2021-Dec-19 at 09:24

The logic of comparing files seems alright, I don't find any outstanding problem with it, it is ok to prepend the "/" to match what you need. Could be even better if you could use the System.IO.Path.DirectorySeparatorChar for the directory root path as well, so if you run on windows or Linux you will have no issues.

But there may be a conceptual problem with what you are doing. To my understanding you aim to verify existence of specific configuration files required for your program to work right, if those files are missing than the program should fail. But that kind of failure due to missing configuration files, is an expected and valid result of your code. Yet, you unit-test this as if missing files should fail the test, as if missing files are an indication that something wrong with your code, this is wrong.

Missing files are not indication of your code not working correct and Unit-test should not be used as a validator to make sure the files exist prior executing the program, you will likely agree that unit-test is not part of the actual process and it should only aim to test your code and not preconditions, the test should compare an expected result (mock result of your code) vs. actual result and certainly not meant to become part of the code. That unit test looks like a validator that should be in the code.

So unless those files are produced by your specific code (and not the deployment) there is no sense testing that. In such case you need to create a configuration validator code - and your unit test could test that instead. So it will test that the validator expected result with a mock input you provide. But the thing here is that you would know that you only testing the validation logic and not the actual existence of the files.

Problem parsing through multiple elements in the XUnit XML file using XElement

ANSWER

Answered 2021-Nov-20 at 22:35

Your code has a couple problems:

The elements are not direct children of the root element, so xelement.Elements().Where(e => e.Name.LocalName == "test") does not select anything. You need to descend deeper into the hierarchy, e.g. with Descendants().
The message text is contained in an indirect child element of the node, specifically failure/message. You need to select this element to get the message.

result.Attribute("message").Value will not work because the XElement.Attribute(XName) method selects an XML attribute rather than an element.

See: XML attribute vs XML element.

Putting those two points together, your code should look like:
