FluentSpecifications
A simple fluent API for writing tests in the given/when/then format.
Access the API using the FluentSpecBuilder class and use the Given, When and Then methods to define your tests.
Each method accepts a free-text label description and an Action delegate, which represents the code that will be executed.
Each method has a corresponding overload that accepts a free-text label description and a Func<Task> delegate. These are used when the delegates are called asynchronously.
You can download the NuGet package from NuGet.org
Examples
int x = default, y = default, result = default;
new FluentSpecBuilder()
.Given("The initial value of x is 1", () => x = 1)
.And("The initial value of y is 3", () => y = 3)
.When("I add x and y together", () => result = x + y)
.Then("The result will be 4", () => result.Should().Be(4));The same as above, but using async delegates:
int x = default, y = default, result = default;
new FluentSpecBuilder()
.Given("The initial value of x is 1", async () => await Task.Run(() => x = 1))
.And("The initial value of y is 3", async () => await Task.Run(() => y = 3))
.When("I add x and y together", async () => await Task.Run(() => result = x + y))
.Then("The result will be 4", async () => await Task.Run(() => result.Should().Be(4)));
