Fluent assertion for OR condition

Question

I am trying to set up the fluent assertion for the below condition. But couldnt find a method with expression or an ObjectAssertion with Or().

I got to check the status of my service is of enum value Pending or Active

services.Should().HaveCount(totalServices).And.BeOfType<Service>().Which.ServiceStatusKey.Should().Be(Status.Pending); 

I want something like,

.Be(Status.Pending).Or().Be(Status.Active) 

Could someone please help me achieving this.

Answer 1

You can use Match for this case.

ServiceStatusKey.Should().Match<Status>(p=>p==Status.Pending || p == Status.Active); 

FluentAssertions does not support an Or()-statement. Use Match() for general purpose assertions.

Answer 2

Try this way:

(services.Status == Status.Pending || services.Status == Status.Active).Should().BeTrue("Message when it is false.");
