Testing

import Tabs from '@theme/Tabs'; import TabItem from '@theme/TabItem';

make test will run the node-based tests. By default it runs tests on files in every supported format. To test a specific file type, set FMTS to the format you want to test. Feature-specific tests are available with make test_misc

$ make test_misc   # run core tests
$ make test        # run full tests

To enable all errors, set the environment variable WTF=1:

$ make test        # run full tests
$ WTF=1 make test  # enable all error messages

flow and eslint checks are available:

$ make lint        # eslint checks
$ make tslint      # check TS definitions

The core in-browser tests are available at tests/index.html within this repo. Start a local server and navigate to that directory to run the tests. make ctestserv will start a server on port 8000.

make ctest will generate the browser fixtures. To add more files, edit the tests/fixtures.lst file and add the paths.

make test-bun will run the full Bun test suite and make test-bun_misc will run the smaller feature-specific tests.

make test-deno will run the full Deno test suite and make test-deno_misc will run the smaller feature-specific tests.

make dist will build xlsx.extendscript.js.

The script estk.jsx at the root of the project is configured to run in ExtendScript Toolkit. It will read sheetjs.xlsx and attempt to write test files in a number of file formats.

ExtendScript Toolkit 3.5 is available as a standalone download for Windows.

Tested Environments

(click to show)

Browsers

  • IE 6/7/8/9/10/11 (IE 6-9 require shims)
  • Chrome 26+ (including Android 6.0+)
  • Safari 8+ (Desktop) and Safari 10+ (iOS)
  • Edge 13-18 and 79+
  • FF Latest

The automated browser tests seek to test the latest patch version of each major release of Chromium ending in 0 (starting from Chrome 30).

Edge originally was an independent browser, becoming a Chromium fork in version 79. Since the new releases should be nearly identical to the Chrome counterpart, the Edge tests are run on major releases ending in 5 (starting from Edge 85).

Server Platforms

  • NodeJS 0.8, 0.10, 0.12, and every major version starting from 4
  • io.js 1/2/3
  • Deno latest

The test suite also includes tests for various time zones. To change the timezone locally, set the TZ environment variable:

$ env TZ="Asia/Kolkata" WTF=1 make test_misc

Test Files

Test files are housed in another repo.

Running make init will refresh the test_files submodule and get the files. The "OS-Specific Setup" includes notes for installing the required dependencies.
