Cappadonna
Headless browser testing for tap with coverage reporting.
Cappadonna merges several tools together for integrated testing.
Example:
const path = require('path')
const cappadonna = require('cappadonna')
const test = cappadonna(path.join(__dirname, 'bundle-entry-point.js'))
test('basic test', async (page, t) => {
t.plan(1)
let str = '<test-element>pass</test-element>'
await page.appendAndWait(str, 'test-element')
await page.evaluate(() => {
t.same('pass', document.querySelector('test-element').textContent)
})
})
$ tap tests/test-*.js --coverage
When coverage is enabled all code, including what gets bundled and sent to the browser, will be instrumented and included in coverage.
The test function and t variable are part of tap and document here.
The page object is part of puppeteer and documented here.
page.appendAndWait(htmlString, selector)
Appends the htmlString to the page's body and waits for the selector to
return true.
