How to get Mocha to fail a test

Question

I have the following test:

it.only(\'validation should fail\', function(done) {
    var body = {
        title: \"dffdasfsdfsdafddfsadsa\",
        description:          


        

Answer 1

You can call assert.fail:

it("should return empty set of tags", function()
{
    assert.fail("actual", "expected", "Error message");
});

Also, Mocha considers the test has failed if you call the done() function with a parameter.

For example:

it("should return empty set of tags", function(done)
{
    done(new Error("Some error message here"));
});

Though the first one looks clearer to me.
