file upload and download

Attaching files #

You can use the attach API to upload files in your test scripts as follows

const { goto, fileField, button, above, attach, click, text } = require('taiko'),

(async () => { try { await openBrowser(); await goto('http://example.org/upload'); await attach(path.join(__dirname, 'data', 'foo.txt'), fileField(above(button('Upload')))); await click('Upload'); } catch (e) { console.error(e); } finally { await closeBrowser(); } })();

The code above attaches the file data/foo.txt from the current folder to a file field near a button with the name 'Upload'. You can also use the fileField API with other selectors.

Downloading files #

The following code shows how to configure a Taiko test to download files

const { goto, client, click } = require('taiko'), path = require('path'), fs = require('fs'), assert = require('assert')

(async () => { var downloadPath = path.resolve(__dirname, 'data', 'downloaded'); try { await openBrowser(); await client().send('Page.setDownloadBehavior', { behavior: 'allow', downloadPath: downloadPath, }); await goto('http://example.org/download');

// ensure that file_upload.js is run before this, // to allow the file to be available for download await click('foo.txt'); sleep(1000); expect(path.join(downloadPath, 'foo.txt')).to.exist;

assert.ok(fs.existsSync(path.join(downloadPath, 'foo.txt'))) } catch (e) { console.error(e); } finally { await closeBrowser(); if (fs.existsSync(path.join(downloadPath, 'foo.txt'))) { fs.unlinkSync(path.join(downloadPath, 'foo.txt')); } } })();

You can also use node's fs API to read the contents of the file and use it in your assertions.
