Class AbstractAcceptanceTest

A class that can be used as a basis for running acceptance tests with Function Monkey at the command dispatch level designed for use with test frameworks that take a constructor approach to

One of the advantages of the pattern used by Function Monkey is that the host function triggers are separated cleanly from business logic and compiled with pre-tested templates allowing for comprehensive acceptance tests to be run just below this level which can often provide a high level of value with a lower level of complexity than also testing the Function triggers.

Typically the none-generic version of this class is more useful but this version allows for a custom IFunctionHostBuilder to be used if additional functionality is required over and above that baked into the supplied TestFunctionHostBuilder which solely handles command registration and dependency injection management.

BeforeServiceProviderBuild(IServiceCollection, ICommandRegistry)

This method can be used to modify dependency and command setup before the service provider has been built from the service collection.

This must not access members (and should not need to) as it is invoked from the constructor to support test frameworks such as XUnit that construct test cases this way.

Declaration
public virtual void BeforeServiceProviderBuild(IServiceCollection serviceCollection, ICommandRegistry commandRegistry)
Parameters
Type Name Description
IServiceCollection serviceCollection
ICommandRegistry commandRegistry

BeforeSetup()

Called during construction before setup is called (overriding methods cannot use member data)

Declaration
protected virtual void BeforeSetup()

ExecuteHttpAsync(ICommand, HttpMethod)

Runs a command through the IActionResult ASP.Net pathways and returns a HTTP response. This is useful for testing end to end HTTP triggered functions without having to actually host the function app. A method only needs specifying in the function supports multiple methods.

Declaration
public Task<HttpResponse> ExecuteHttpAsync(ICommand command, HttpMethod method = null)
Parameters
Type Name Description
ICommand command
HttpMethod method
Returns
Type Description
Task<HttpResponse>

ExecuteHttpAsync<TResult>(ICommand<TResult>, HttpMethod)

Runs a command through the IActionResult ASP.Net pathways and returns a HTTP response. This is useful for testing end to end HTTP triggered functions without having to actually host the function app. A method only needs specifying in the function supports multiple methods.

Declaration
public Task<HttpResponse> ExecuteHttpAsync<TResult>(ICommand<TResult> command, HttpMethod method = null)
Parameters
Type Name Description
ICommand<TResult> command
HttpMethod method
Returns
Type Description
Task<HttpResponse>
Type Parameters
Name Description
TResult
