Frontend test skeletons

Frontend tests are done in Cypress. Code is located at cypress. The test cases are in cypress/testcases. The way that they are organized are in describe and it blocks. Cypress uses Mocha to do BDD. An it block is a test case, and a describe block it a suite of tests with it blocks inside of it.

The test skeleton is just a stub method with JSDoc comments that add steps. Here's an example of a test skeleton for logging in. You would put this in the appropriate test spec in cypress/testcases. For login it would be login.spec.ts. Since it's not implemented you will also add the notImplemented tag.

/**
* 1. Load login page
* 2. Enter in username and password
* 3. Click Login
* 4. Verify that the dashboard loads
* @notImplemented
*/
export function loginTest() {}

It's worth noting that this function and docs can't be inside of a describe or it block for them to show correctly in our static site generator.

The test skel does not include the describe or it block, but here's an example of a fully implemented test spec with just an it block from settings.spec.ts

/**
 * 1. Login
 * 2. Navigate to the Advanced Settings Page via the sidebar
 */
export function navigateAdvanceSettingsPage() {};
it('should navigate to the Advanced Settings Page', () => {
    login.login();
    sidebar.advancedSettings();
});

Here's an example with a describe block from login.spec.ts

/**
 * This is the login spec
 * 1. Login for first time
 * 2. Login with already set password
 */
describe('login page for harvester', () => {
    it('should login the first time', () => {
        const login = new LoginPage();
        login.firstLogin();
    });
    
    it('should login successfully', () => {
        const login = new LoginPage();
        login.login();
    });
});

Here's an example with both a describe and an it block from support.spec.ts

/**
 * 1. Login
 * 2. Navigate to the support page
 * 3. Validate the URL
 */
export function checkSupportPage() {}
describe('Support Page', () => {
    it('Check suport page', () => {
        login.login();
        support.visitSupportPage();
    });
});

/**
 * 1. Login
 * 2. Navigate to the support page
 * 3. Click Generate Support Bundle
 * 4. Input Description
 * 5. Click Generate
 * 6. Wait for download
 * 7. Verify Downlaod
 * @notImplementedFully
 */
export function generateSupportBundle() {}
it('Generate Support Bundle', () => {
    login.login();
    support.generateSupportBundle('this ia a test description');
});

View the test result

The docker image will automatically run cypress test and upload the test result to the minio server. The default bucket name is cypress-test-report, and the default dir path is cypress/results/.

You can view the test result by clicking here for or using the following command:

./scripts/list-reporters
