Fluent Asserts

Build Status DUB Version DUB Installs

Writing unit tests is easy with Dlang. The unittest block allows you to start writing tests and to be productive with no special setup.

Unfortunately the assert expresion does not help you to write expressive asserts, and in case of a failure it's hard to find why an assert failed. The fluent-assert allows you to more naturally specify the expected outcome of a TDD or BDD-style test.

To begin

  1. Add the DUB dependency: https://code.dlang.org/packages/fluent-asserts
  2. Import it:
import fluent.asserts;
  1. Use it:
    unittest {
        true.should.equal(false);
    }
  1. Run the tests:
➜  dub test --compiler=ldc2

API Docs

The library uses the should template in combination with Uniform Function Call Syntax (UFCS)

auto should(T)(lazy const T testData);

So the following statements are equivalent

exepectedValue.should.equal(42);
should(expectedValue).equal(42);

In addition, the library provides a not modifier that negates the assert condition:

exepectedValue.should.not.equal(42);
