Mocking (spying and stubbing functions)
Mock function generation
Myrtle has a sister project called Tyrtle which you might also like!
Tyrtle has been designed for simplicity and legibility, with minimal pollution of the global namespace.
Here's an example of how you can write an assertion:
assert.that(Math.sqrt(49)).is(7).since("The square root of 49 should be 7");
If that's too much typing for you, it's good to know that Tyrtle gives you a fine heaping of syntactic sugar:
since are all completely optional! If you prefer a terser syntax, the exact same assertion can be written like this:
assert(Math.sqrt(49))(7)("The square root of 49 should be 7");
