One common - * mistake is to accidentally invoke the function yourself instead of letting - * the `throw` assertion invoke the function for you. For example, when - * testing if a function named `fn` throws, provide `fn` instead of `fn()` as - * the target for the assertion. - * - * expect(fn).to.throw(); // Good! Tests `fn` as desired - * expect(fn()).to.throw(); // Bad! Tests result of `fn()`, not `fn` - * - * If you need to assert that your function `fn` throws when passed certain - * arguments, then wrap a call to `fn` inside of another function. - * - * expect(function () { fn(42); }).to.throw(); // Function expression - * expect(() => fn(42)).to.throw(); // ES6 arrow function - * - * Another common mistake is to provide an object method (or any stand-alone - * function that relies on `this`) as the target of the assertion. Doing so is - * problematic because the `this` context will be lost when the function is - * invoked by `.throw`; there's no way for it to know what `this` is supposed - * to be. There are two ways around this problem. One solution is to wrap the - * method or function call inside of another function. Another solution is to - * use `bind`. - * - * expect(function () { cat.meow(); }).to.throw(); // Function expression - * expect(() => cat.meow()).to.throw(); // ES6 arrow function - * expect(cat.meow.bind(cat)).to.throw(); // Bind - * - * Finally, it's worth mentioning that it's a best practice in JavaScript to - * only throw `Error` and derivatives of `Error` such as `ReferenceError`, - * `TypeError`, and user-defined objects that extend `Error`.
