CSV and table recipe

Loads CSV file and checks HTML table to have the text content matching the loaded CSV records

Uses neat-csv to parse the loaded CSV text into records.

Tests

• spec.cy.js loads the CSV file using cy.readFile, parses the text into list of objects, then goes through the rows of the table element comparing cell text content to the records.

Speed

The spec file has 4 tests. The slowest wraps every access to the table's row and cell in a Cypress alias variable. While convenient, unless the cell's values are changing and need to retry assertions, it introduces performance overhead.

The spec includes a few additional tests that avoid aliases and run much faster:

• access every row then use the DOM to access and check each child cell
• access every row, extract innerText from every cell and compare the entire list at once
• access the entire table, extract innerText from every cell and compare the entire list of values at once

We can get the test duration by subscribing to the test:after:run event.

Cypress.on('test:after:run', (attributes) => {
  console.log('Test "%s" has finished in %dms', attributes.title, attributes.duration)
})
