qunit/no-throws-string

📝 Disallow assert.throws() with block, string, and message args.

💼 This rule is enabled in the ✅ recommended config.

QUnit 2.0 has deprecated the assert.throws(block, string, message) form of assert.throws(). This rule can be used to flag uses of the deprecated form and convert them to use a regular expression or some other predicate.

Rule Details

The following patterns are considered warnings:

QUnit.test('test', function (assert) {
    assert.throws(function () {
        // code
    }, "error message", "An error should have been thrown");
});

The following patterns are not warnings:

QUnit.test('test', function (assert) {
    assert.throws(function () {
        // code
    }, /error message/, "An error should have been thrown");
});

QUnit.test('test', function (assert) {
    assert.throws(function () {
        // code
    }, "An error should have been thrown");
});

QUnit.test('test', function (assert) {
    assert.throws(function () {
        // code
    }, function (err) { return true; }, "An error should have been thrown");
});

When Not To Use It

This rule can be safely disabled if you are not using QUnit 2.0.
