Methods

Adds a function class that can be resolved from the test host.

public AzureFunctionTestHostBuilder AddFunction<TFunction>() where TFunction : class

TFunction: The reference-type function class registered with transient lifetime.

Creates the configured function test host.

public AzureFunctionTestHost Build()

AzureFunctionTestHost: A new host that owns its service provider and must be disposed. Registered singleton and scoped disposable services are released with the host or invocation scope respectively.

Configures dependencies used by function instances and invocation contexts.

public AzureFunctionTestHostBuilder ConfigureServices(Action<IServiceCollection> configure)

configure Action<IServiceCollection>: A non-null callback invoked synchronously once with the builder-owned mutable service collection. It may add, remove, or replace registrations but must not retain the collection.

Adds inline middleware to the test invocation pipeline.

public AzureFunctionTestHostBuilder UseMiddleware(Func<FunctionContext, FunctionExecutionDelegate, Task> middleware)

middleware Func<FunctionContext, FunctionExecutionDelegate, Task>: A non-null asynchronous delegate retained by the host and invoked once per invocation in registration order. It may short-circuit by not invoking the supplied next delegate.

Adds isolated-worker middleware to the test invocation pipeline.

public AzureFunctionTestHostBuilder UseMiddleware<TMiddleware>() where TMiddleware : class, IFunctionsWorkerMiddleware

AzureFunctionTestHostBuilder: This builder, for chaining. Middleware executes in registration order.

TMiddleware: The middleware class registered transiently and resolved once per invocation from its scope.
