What is @types/qunit?
@types/qunit provides TypeScript type definitions for the QUnit JavaScript testing framework. It allows developers to write QUnit tests in TypeScript, ensuring type safety and better development experience.
What are @types/qunit's main functionalities?
Defining Test Modules
This feature allows you to define a test module with setup and teardown hooks. The hooks object provides beforeEach and afterEach methods to run code before and after each test in the module.
QUnit.module('Module Name', hooks => {
hooks.beforeEach(() => {
// setup code
});
hooks.afterEach(() => {
// teardown code
});
});
Writing Test Cases
This feature allows you to write individual test cases. The assert object provides various assertion methods to validate the test conditions.
QUnit.test('Test Name', assert => {
assert.ok(true, 'This test will pass.');
assert.equal(1 + 1, 2, '1 + 1 equals 2');
});
Asynchronous Testing
This feature allows you to write asynchronous tests. The assert.async() method returns a callback that you can call when the asynchronous operation is complete.
QUnit.test('Asynchronous Test', assert => {
const done = assert.async();
setTimeout(() => {
assert.ok(true, 'Async test passed.');
done();
}, 1000);
});
