What is @types/jasminewd2?
@types/jasminewd2 provides TypeScript definitions for jasminewd2, which is a library that integrates Jasmine with WebDriver for end-to-end testing in Angular applications.
What are @types/jasminewd2's main functionalities?
Asynchronous Testing
This feature allows you to write asynchronous tests using async/await syntax, making it easier to handle promises and asynchronous operations in your tests.
describe('Async Test', () => {
it('should wait for async operation', async () => {
await browser.get('http://example.com');
const title = await browser.getTitle();
expect(title).toBe('Example Domain');
});
});
Custom Matchers
This feature allows you to define custom matchers to extend Jasmine's built-in matchers, providing more flexibility in your test assertions.
describe('Custom Matcher', () => {
beforeEach(() => {
jasmine.addMatchers({
toBeValid: () => ({
compare: (actual) => ({
pass: actual !== null && actual !== undefined,
message: 'Expected value to be valid'
})
})
});
});
it('should validate custom matcher', () => {
expect('some value').toBeValid();
});
});
Handling Promises
This feature allows you to handle promises directly in your tests, making it easier to work with asynchronous operations without using async/await.
describe('Promise Handling', () => {
it('should handle promises', (done) => {
browser.get('http://example.com').then(() => {
return browser.getTitle();
}).then((title) => {
expect(title).toBe('Example Domain');
done();
});
});
});
Other packages similar to @types/jasminewd2
@types/jasmine
@types/jasmine provides TypeScript definitions for Jasmine, a popular testing framework for JavaScript. While @types/jasminewd2 is specifically designed for integration with WebDriver, @types/jasmine is more general-purpose and does not include WebDriver-specific features.
@types/protractor
@types/protractor provides TypeScript definitions for Protractor, an end-to-end test framework for Angular applications. Protractor itself integrates with Jasmine and WebDriver, making it a more comprehensive solution compared to @types/jasminewd2, which focuses solely on the Jasmine-WebDriver integration.
@types/selenium-webdriver
@types/selenium-webdriver provides TypeScript definitions for Selenium WebDriver, a tool for automating web application testing. While @types/jasminewd2 focuses on integrating Jasmine with WebDriver, @types/selenium-webdriver provides a broader set of definitions for working directly with WebDriver.
