Describe the bug
Compared to the use cases for IHostBuilder and IWebHostBuilder, WebApplicationFactory<T> does not set the default environment for the application under test to Development when the code path for minimal hosting is used.
|
hostBuilder?.UseEnvironment(Environments.Development); |
|
return builder.UseEnvironment(Environments.Development); |
|
var hostBuilder = CreateHostBuilder(); |
|
if (hostBuilder is not null) |
|
{ |
|
ConfigureHostBuilder(hostBuilder); |
|
return; |
|
} |
|
|
|
var builder = CreateWebHostBuilder(); |
|
if (builder is null) |
|
{ |
|
var deferredHostBuilder = new DeferredHostBuilder(); |
|
// This helper call does the hard work to determine if we can fallback to diagnostic source events to get the host instance |
|
var factory = HostFactoryResolver.ResolveHostFactory( |
|
typeof(TEntryPoint).Assembly, |
|
stopApplication: false, |
|
configureHostBuilder: deferredHostBuilder.ConfigureHostBuilder, |
|
entrypointCompleted: deferredHostBuilder.EntryPointCompleted); |
|
|
|
if (factory is not null) |
|
{ |
|
// If we have a valid factory it means the specified entry point's assembly can potentially resolve the IHost |
|
// so we set the factory on the DeferredHostBuilder so we can invoke it on the call to IHostBuilder.Build. |
|
deferredHostBuilder.SetHostFactory(factory); |
|
|
|
ConfigureHostBuilder(deferredHostBuilder); |
|
return; |
|
} |
Adding the missing line itself does not seem to work though, possibly related to #33876 - I've got some tests from debugging this locally I'll push up into a PR shortly see #33890.
To Reproduce
Inspect the IHostEnvironment.EnvironmentName property in, for example, the HelloWorld test.
|
[Fact] |
|
public async Task HelloWorld() |
|
{ |
|
// Arrange |
|
var expected = "Hello World"; |
|
|
|
// Act |
|
var content = await Client.GetStringAsync("http://localhost/"); |
|
|
|
// Assert |
|
Assert.Equal(expected, content); |
|
} |
