Equivalent of NUnit or Jasmine statements for Python?

Question

Using the Python unittest, I found that I lacked clean, descriptive ways to write unit test statements, such as those made in NUnit or Jasmine :

# NUnit Expect(collection, Has.None.EqualTo(DateTime.Now).Within(3).Hours); # Jasmine expect(pi).not.toBeCloseTo(e, 2); 

Is there an existing Python library that provides such assertion methods, preferably compatible with the Python unittest library?

Answer 1

What about PyHamcrest ?

 assert_that(biscuit, equal_to(biscuit)) assert_that(biscuit, instance_of(Biscuit)) assert_that(biscuit, is_in(jar))
